1. This value can vary depending on how the stove
is operated, the type and moisture content of the fuel
used, as well as the design, construction and climatic
location of your home. Figures shown are based on
maximum fuel consumption obtained under laboratory
conditions and on average efficiencies.

2. These values are based on operation in building
code-conforming homes under typical winter climate
conditions in New England. If your home is of nonstan­dard construction (e.g., unusually well insulated, not in­sulated, built underground, etc.) or if you live in a more
severe or more temperate climate, these figures may
not apply. Since so many variables affect performance,
consult your Vermont Castings Authorized Dealer to
determine realistic expectations for your home.

SAFETY NOTICE: IF YOUR STOVE IS NOT PROP­ERLY INSTALLED, A HOUSE FIRE MAY RESULT. TO
REDUCE THE RISK OF FIRE, FOLLOW THE INSTAL­LATION INSTRUCTIONS. CONTACT LOCAL BUILD­ING OR FIRE OFFICIALS ABOUT RESTRICTIONS
AND INSTALLATION INSPECTION REQUIREMENTS
IN YOUR AREA.

Before you begin an installation, review your plans to
see that:

• Your stove and chimney connector will be far

enough from combustible material to meet all
clearance requirements.

• The floor protector is large enough and is con-

structed properly to meet all requirements.

• You have all necessary permits from local author-

ities.
Your local building official is the final authority for ap­proving your installation as safe and determining that it
meets local and state codes.

The metal label permanently attached to the back of
every Vermont Castings stove indicates the stove has
been tested to current ULC standards, by Canadian
Standards Association (CSA). The test standards are
ANSI/UL-1482 and ANSI/UL-737 for the United States
and ULCS627 and CAN/CSA-B366.2 for Canada.
Clearance and installation information also is printed
on the label. When the stove is installed according to
the information both on the label and in this manual,
local authorities in most cases will accept the label as
evidence that the installation meets codes and can be
approved.

However, codes vary in different areas. Before starting
the installation, review your plans with the local building
authority. You local dealer can provide any additional
information needed.

For any unresolved installation issues, refer to CSA
CAN-B365 Installation Code for Solid Fuel Burning Ap­pliances and Equipment. These standards are the basis
for many national codes. They are nationally recog­nized and are accepted by most local authorities. Your
local dealer or your local building official may have a
copy of these regulations.

IMPORTANT: FAILURE TO FOLLOW THESE IN­STALLATION INSTRUCTIONS MAY RESULT IN A
DANGEROUS SITUATION, INCLUDING A CHIMNEY
OR HOUSE FIRE. FOLLOW ALL INSTRUCTIONS
EXACTLY, AND DO NOT ALLOW MAKESHIFT COM­PROMISES TO ENDANGER PROPERTY AND PER­SONAL SAFETY.

Outside Air

In some modern, super-insulated homes, there is not
enough air for combustion because of insufficient air
infiltration into the building. Such air enters a home
through unsealed cracks and openings. Kitchen or bath
exhaust fans can compete with the stove for available
air and compound the problem.

When poor draft is caused by a low infiltration rate,
opening a ground floor window on the windward side
of the house and in the vicinity of the stove will usually
alleviate the problem.

Another solution is to install a permanent outside air
supply to the stove and/or room. In some areas, in
fact, bringing air for combustion from outside the home
directly to the air inlet of the stove is required for new
construction.

An outside air supply is not affected by pressure varia
tions within the house, and improved stove perfor­mance often results. An Outside Air Adaptor Kit for the
Intrepid II is available from your local Vermont Castings
dealer.

What Kind of Chimney to Use

Your Intrepid II must be connected to a code-approved
masonry chimney with a flue liner, to a relined masonry
chimney that meets local codes, or to a prefabricated
metal chimney that complies with the requirements
for Type HT chimneys in the Standard for Chimneys,
Factory-Built, Residential Type and Building Heating
Appliance, UL 103, or the High Temperature (650°C)
Standard ULC S-629 for Canada. Whatever kind you
use, the chimney and chimney connector must be in
good condition and kept clean. Figure 2 shows the two
chimney types.

If you use an existing masonry chimney, it must be
inspected to ensure safe condition before the stove is
installed. Your local professional chimney sweep, build­ing inspector, or fire department official will be able to
inspect the chimney or provide a referral to someone
who can.

The chimney must extend at least 3’ (914mm) above
the highest point where it passes through a roof, and at
least 2’ (610mm) higher than any portion of a building
within 10’ (3m). (Fig. 3)

For proper draft and good performance, any chimney
used with an Intrepid II should extend at least 16’ (5m)
above the flue collar of the stove.

Reference Point

Fig. 3 The 2’-3’-10’ Chimney Rule.

AC617

Masonry Chimneys

An inspection of the chimney must confirm that it has
a lining. Do not use an unlined chimney. The chimney
should have no cracks, loose mortar, other signs of
deterioration, or blockage. Repair any defects before
using the chimney with your stove.

Seal any unused openings in an existing masonry chim
ney with masonry to the thickness of the chimney wall,
and repair the chimney liner. Openings sealed with pie
plates or wallpaper are a hazard; seal them with mortar
or refractory cement. In the event of a chimney fire,
flames and smoke may be forced out of these unused
thimbles.

The chimney should be thoroughly cleaned before use.

A newly-built masonry chimney must conform to the
standards of your local building code or, in the absence
of a local code, to a recognized national code. Masonry
chimneys must be lined, either with code-approved ma­sonry or pre-cast refractory tiles, stainless steel pipe, or
a code-approved, “poured-in-place” liner. The chimney’s
clean-out door must seal tightly.

Prefabricated Chimneys

A prefabricated metal chimney must be one tested and
listed for use with solid-fuel burning appliances to the
High Temperature (650°C) Standard ULC S-629 for
Canada.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.

Chimney Size

An Intrepid II is approved for venting into a masonry
chimney with a maximum flue size of 8” x 8” (200 x
200mm), and into a round flue size of 6” (150mm).

It may not be vented into larger chimneys without a liner
to reduce the effective flue size to 6”(150mm) diam
eter. Larger chimneys must have their flues relined for
proper stove performance.

Accessories to make the connection between stainless
steel chimney liners and your Intrepid II are available
through your local dealer.

Chimney Connector Guidelines

Chimney connector is the double-wall or single-wall
pipe that connects the stove to the chimney. The chim­ney is a masonry or prefabricated structure that enclos­es the flue. Chimney connectors are used only to make
the connection from the stove to the chimney.

Double-wall chimney connectors must be tested and
listed for use with solid-fuel burning appliances. Sin­gle-wall chimney connectors should be made of 24
gauge or heavier steel, and should be 6” (150 mm) in
diameter. Do not use galvanized connector; it cannot
withstand the high temperatures that can be reached by

-

smoke and gases, and may release toxic fumes under
high heat.

If possible, do not pass the chimney connector through
a combustible wall or ceiling. If passage through a com­bustible wall is unavoidable, refer to the section follow­ing on Wall Pass-Throughs. Do not pass the chimney
connector through an attic, a closet, or any similar con­cealed space. The whole connector should be exposed
and accessible for inspection and cleaning.

In horizontal runs of single-wall chimney connector
without protective shields, maintain a clearance of at
least 26” (660mm) from the ceiling. For information on
reduced clearances using shields on single-wall chim­ney connector or using double-wall connectors, see the
clearance chart on Page 10.

-

2000966

Intrepid II Woodburning Stove

Keep the horizontal run of chimney connector as short
and direct as possible, with no more than two 90° turns.
Slope horizontal runs of connector upward 1/4” per foot
(20mm per m) going from the stove toward the chim­ney. The recommended maximum length of a horizontal
run is 3’ (914mm). The recommended total length of
chimney connector is 8’ (2.4m).

In cathedral ceiling installations, extend the prefabri­cated chimney down to within 8’ (2.4m) of the stove.

SAFETY NOTE: ALWAYS WEAR GLOVES AND PRO
TECTIVE EYEWEAR WHEN DRILLING, CUTTING OR
JOINING SECTIONS OF CHIMNEY CONNECTOR.

Double-wall Chimney Connector

The listing for the Intrepid II for the U.S. and Canada
includes use of double-wall chimney connectors that
have been tested and listed for use with solid-fuel burn­ing appliances by a recognized testing laboratory.

Information on assembling and installing double-wall
connector is provided by the manufacturer of the
double-wall pipe. Follow the manufacturer’s instructions
exactly as you assemble the connector and attach it to
the stove and chimney. Using connectors and chim­neys from the same manufacturer makes the assembly
and installation straightforward.

NOTE: For installations using double-wall con­nectors, minimum clearances must conform to the
listed clearances in the clearance chart on Page 14.

• Be sure the installed stove and chimney connector

are correct distances from nearby combustible material.

NOTE: Special slip pipes and thimble sleeves that form
telescoping joints between sections of chimney con­nector are available to simplify installations. They often
eliminate the need to cut individual connector sections.
Consult your local dealer about these special pieces.

Securing the Single-wall Connector to a

-

For prefabricated chimneys, follow the installation
instructions of the chimney maker exactly as you install
the chimney. The maker of the chimney will supply the
accessories to support the chimney, either from the roof
of the house, at the ceiling of the room where the stove
is installed, or from an exterior wall.

Special adapters are available from your local dealer to
make the connection between the prefabricated chim­ney and the chimney connector. The top of such adapt­ers attaches directly to the chimney or to the chimney’s
ceiling support package, while the bottom of the adap­tor is screwed to the chimney connector.

These adapters are designed so the top end will fit
outside the inner wall of the chimney, and the bottom
end will fit inside the first section of chimney connector.
When assembled in this way, any soot or creosote fall­ing from the inner walls of the chimney will stay inside
the chimney connector.

Prefabricated Chimney

Single-wall Chimney Connector

• Beginning at the flue collar of the stove, assemble the

chimney connector. Insert the first crimped end into the
stove’s flue collar, and keep each crimped end pointing
toward the stove. Using the holes in the flue collar as
guides, drill 1/8” (3mm) holes in the bottom of the first
section of chimney connector and secure it to the flue
collar with three #10 x 1/2”
sheet metal screws.

• Secure each joint be-

tween sections of chimney
connector, including tele­scoping joints, with at least
three sheet metal screws.
The pre-drilled holes in
the top of each section of
chimney connector serve as
guides when you drill 1/8”
(3mm) holes in the bottom
of the next section.

• Secure the chimney

connector to the chimney.

The opening through the chimney wall to the flue (the
“breach”) must be lined with either a ceramic or metal
cylinder, called the “thimble”, which is cemented firmly
in place. The fit must be snug and the joint between the
thimble and the chimney wall must be cemented. (Fig.

A special piece called the “thimble sleeve,” slightly
smaller in diameter than standard connector and most
thimbles, will facilitate the removal of the chimney con­nector system for inspection and cleaning. Thimble
sleeves should be available from your local dealer. (Fig.

positioned on the hearth in front of the fireplace and the
chimney connector rises from the stove top and then
angles ninety degrees back into the chimney. (Fig. 7)

To install a thimble sleeve, slide it into the breach until
it is flush with the inner flue wall. Do not extend it into
the actual flue passage, as this could interfere with the
draft.

The thimble sleeve should protrude 1-2” (25-50mm) into
the room. Use furnace cement and thin gasketing to
seal the sleeve in place in the thimble. Secure the chim­ney connector to the outer end of the sleeve with sheet
metal screws.

Without a thimble, a suitable length of chimney con­nector can be extended through the breach to the inner
face of the flue liner, and cemented securely in place.
Additional pieces of connector are then attached with
sheet metal screws.

If the chimney connector from your installation enters
the chimney above a fireplace, follow all the guidelines
mentioned above for freestanding installations. In addi­tion, give special consideration to the following points:

• Check the clearance between the stove and the

chimney connector, and any combustible trim or the
mantel. Use the necessary combination of mantel, trim,
and connector heat shields to achieve the required
clearances.

• Check the clearance between the chimney con-

nector and the ceiling. If no heat shields are used, the
clearance should be at least 26” (660mm). To find out
how much this clearance may be reduced with heat
shields, see the clearance chart on Page 14.

• The fireplace damper must be sealed to prevent

room air from escaping up the flue. However, it must be
possible to re-open the damper to inspect or clean the
chimney.

Fireplace Chimney Installations -

Through a Fireplace

If your fireplace height is at least 25” (635mm), you
may install an Intrepid II with standard legs through
the fireplace opening using a “positive connection” kit
available from your local dealer. These positive connec­tion kits ensure a tight fit between the stove flue collar
and the chimney flue. (Fig. 8) Fireplace installations,
whether connected to the flue above or through the
fireplace opening, have special clearance requirements
to adjacent trim and the mantel. You’ll find the required
clearances for the Intrepid II fireplace installations on
Page 14.

Floor protection requirements also apply to fireplace
installations. Floor protection information is on Page 9.

In the United States, the National Fire Protection As­sociation (NFPA) has established guidelines for passing
chimney connectors through combustible walls. Many
building code inspectors follow these guidelines when
approving installations.

Figure 9 shows one NFPA-recommended method.
All combustible material in the wall is cut away from
the single-wall connector to provide the required 12”
(305mm) clearance. Any material used to close up the
opening must be noncombustible.

Three other methods are also recommended by NFPA:

• Using a section of double-wall chimney with a 9”

(230mm) clearance to combustibles.

• Placing a section of chimney connector inside a ven-

tilated thimble, which in turn is separated from combus­tibles by 6” (150mm) of fiberglass insulating material.

• Placing a section of chimney connector inside a

section of 9” (230mm) diameter, solid-insulated, factory­built chimney, with 2” (50mm) of air space between the
chimney section and combustibles.

Wall Pass-Throughs

Whenever possible, design your installation so the con­nector does not pass through a combustible wall. If you
are considering a wall pass-through in your installation,
check with your building inspector before you begin.
Also, check with the chimney connector manufacturer
for any specific requirements.

Accessories are available for use as wall pass­throughs. If using one of these, make sure it has been
tested and listed for use as a wall pass-through.

material in the wall is cut away to provide the required
18” (460 mm) clearance for the connector. The resulting
space must remain empty. A flush-mounted sheet metal
cover may be used on one side only. If covers must be
used on both sides, each cover must be mounted on
noncombustible spacers at least 1” (25 mm) clear of the
wall.

Your local dealer or your local building inspector can
provide details for other approved methods of passing

Most installations will require that the bottom heat
shield be attached. Only when the stove is placed
on a completely noncombustible surface, such as
unpainted concrete over earth, may it be used with­out the bottom heat shield.

Even with the bottom heat shield installed, you must
also use a floor protector.

In the United States, the floor protector required under
the stove must extend at least 16” from the front of the
stove - not from the ashlip - (Labeled ‘E’ in Fig. 11), and
at least 6” from the sides and rear (‘D’, Fig. 11).

To meet the requirement in the United States, a floor
protector must be at least 34” wide and 40” deep.

In Canada, the floor protector required under the stove
must extend 18” (460mm) to the front (labeled ‘E’, Fig.

11), and 8” (200mm) from the sides and rear. (‘D’ ,Fig. 11)

To meet Canadian requirements, a floor protector must
be at least 38” (965 mm) wide and 44” (1118 mm) deep.

Floor protection also must extend under the chimney
connector and 2” (51 mm) to either side. (‘C’, Fig. 11)
For 6” (152 mm) connector used with the Intrepid II, the
protector must be a minimum of 10” (254 mm) wide,
centered under the connector.

NOTE: Do not vent your Intrepid II into a factory-built
(zero-clearance) fireplace. These appliances and their
chimneys are specifically designed as a unit for use as
fireplaces. It may void the listing or be hazardous to
adapt them for any other use.

DO NOT CONNECT AN INTREPID II TO ANY AIR
DISTRIBUTION DUCT OR SYSTEM.

Floor Protection

A tremendous amount of heat radiates from the bottom
plate of an Intrepid II, and the floor beneath requires
two kinds of special protection.

Heat protection is provided by a Bottom Heat Shield,
part #0307.

Spark and ember protection is provided by a floor pro
tector, which may be any noncombustible material.

For a new hearth, we recommend a noncombustible
floor protector such as 1/4” non-asbestos mineral board
or its equivalent, or 24 gauge sheet metal. If carpeting
is present, it must be removed before installation of the
floor protector. The floor protector may be covered with
a noncombustible decorative material if desired. When
using brick, tile, or stone, individual pieces must be
mortared so sparks cannot fall through.

Floor Protection for Fireplace Installations

Do not assume your fireplace hearth is completely
noncombustible.

Many fireplace hearths do not satisfy the “completely
noncombustible” requirement because the brick or
concrete in front of the fireplace opening is supported
by heavy wood framing as in Figure 12. Because heat
passes through brick or concrete readily, it can easily
pass through to the wood. As a result, such fireplace
hearths can be a fire hazard and are considered a com­bustible floor.

Wood framing requires
protection from radiant heat

Fig. 12 Supporting timbers under fireplace hearth are consid­ered to be combustible.

Keep in mind that many raised hearths will extend
less than the required clearance from the front of the
heater when it is installed. In such cases, sufficient floor
protection as described above must be added in front
of the hearth to satisfy the minimum floor protector re­quirement from the front of the stove: 18” (460mm) from
the front in Canada. Fireplace hearths must also offer
the required protection of 8” (203 mm) on either side.

Optional 3” (76 mm) short legs may be used only on
such hearths that meet the width and depth require­ments outlined previously under “floor protection.”

Hearth rugs do not satisfy the requirements for floor
protection.

Fireplace installations also have special clearance
requirements to the side walls, side decorative trim, and
fireplace mantle. Refer to the information on fireplace
and mantel trim shields in this section.

ST247a

Keep the Stove and Connector a

Safe Distance from

Surrounding Materials

Both a stove and its chimney connector radiate heat in
all directions when operating, and dangerous overheat­ing of nearby combustible materials can occur if they
are too close to the heat. A safe installation requires
that adequate clearance be maintained between the
hot stove and its connector and nearby combustibles.

Clearance is the distance between either your stove
(measured from the back edge of the stove’s top plate)
or chimney connector, and nearby walls, floors, the
ceiling, and any other fixed combustible surface. Your
stove has special clearance requirements that have
been established after careful research and testing to
UL and ULC standards. These clearance requirements
must be strictly observed.

In addition, furnishings and other combustible materials
must be kept away from the stove as well. In general, a
distance of 48” (1220 mm) must be maintained between
the stove and moveable combustible items such as dry­ing clothes, furniture, newspapers, firewood, etc. Keep­ing those clearance areas empty assures that nearby
surfaces and objects will not overheat.

Reducing Clearances

Stove clearances may be reduced by using heat shields
attached to the stove. Chimney connector clearances
may be reduced by using heat shields on single-wall
connector, or by using double-wall connector. Clear­ances may also be reduced by using wall shields. All
shielding used to reduce clearances must be listed by a
recognized testing laboratory and approved by the local
regulatory body.

Clearance requirements are established for many dif­ferent installations. In general, the greatest clearance is
required when you are placing a stove and its connec­tor with no heat shields near a wall with no heat shield.

For example, when the Intrepid II is installed parallel
to the rear wall and no shielding is used, it must be at
least 30” (760 mm) from the wall behind it and at least
24” (610 mm) from walls on either side.

If the Intrepid II is installed in a corner and no shields
are used, the corners of the stove must be at least 20”
(510 mm) from nearby walls.

The least clearance is required when both the stove
and its connector, as well as the wall, have heat
shields.

When shields are attached to the stove or chimney
connector, they are mounted 1” - 2” (25-51 mm) away
from the stove or connector surface on non-combustible
spacers. Air flowing between the stove (and/or chimney

10

connector) and nearby shields carries away heat. Do
not block the air flow by filling this empty space with any
insulating material.

The shiny shield surface facing the heat source must be
left unpainted, enabling it to reflect heat back towards
the stove or connector and away from the wall.

Shields are never used on double-wall connectors.

Clearances may be reduced only by means approved
by the regulatory authority, and in accordance with the
clearances listed in this manual.

NOTE: ALCOVE INSTALLATION OF THE INTREPID
II IS NOT PERMITTED IN CANADA.

Stove Heat Shields

The Intrepid II Rear Heat Shield is one way to reduce
the clearance to the rear wall. The rear heat shield may
be installed on either rear- or top-exiting stoves. How­ever, since the chimney connector also radiates heat
toward the wall in top-exiting installations, either single­wall connector with connector heat shields, or listed and
approved double-wall chimney connector should be
used whenever the rear heat shield is used on top-exit­ing stoves.

Clearance reductions with the rear heat shield apply
only to the wall to the rear in parallel installations. Nei­ther the side clearance requirement nor the clearance
requirement in corner installations may be reduced.

Wall Shields

Clearances may be reduced by using a wall shield
constructed of 24 gauge or heavier sheet metal, or of
another non-combustible material such as 1/2” (13 mm)
insulation board or common brick “laid on flat,” with the
3¹⁄₂" (90 mm) side down. Figure 13 shows such a wall
shield.

Shields must be spaced out from the combustible
surface 1" (25mm) on noncombustible spacers. The
spacers should not be directly behind the stove or chim­ney connector.

Air must be able to flow between the wall and the
shield. At least 50% of the bottom 1" (25 mm) of the
shield should be open and the shield must be open at
the top. (Fig. 13)

The wall shield for a stove must extend 10” (254 mm)
above the top of the stove, or a height of 35” (890 mm).
The wall shield for the chimney connector must be 36”
(914 mm) wide, centered behind the connector; for
installations that use an approved prefabricated chim­ney to pass through the ceiling, the chimney connector
shield used with single-wall connector must stop 1”
(25mm) below the ceiling.

Chimney Connector Clearance Reductions

Chimney connector clearances may be reduced by
using heat shields on single-wall connector or by using
double-wall connector. One of these methods should be
used whenever the rear heat shield is used in top-exit
installations, or in any other situation when it is neces­sary to protect nearby combustibles from the heat of the
chimney connector. The ceiling above horizontal runs
of chimney connector must be protected as well if the
clearance is inadequate. Refer to the Clearance Charts.

In top-exiting installations in which the single-wall
connector extends to the ceiling and connects to a
prefabricated insulated metal chimney, the connector
shield must extend to within an inch of the ceiling. A
ceiling heat shield must be installed that is 22” (560mm)
in diameter and, as explained above, that extends 1”
(25mm) below the ceiling. The ceiling shield must be
constructed of 24 gauge or heavier sheet metal, must
be centered on the chimney, and must meet any wall
protector that is also a part of the installation.

For double-wall connector the tested and listed
clearances given in this manual must be used.

Fireplace and Mantel Trim Shields

A fireplace installation requires special clearance be­tween the side of the stove and the right and left walls,
between the side of the stove and the decorative side
trim on the fireplace face, and between the top of the
stove and the mantel.

Fig. 14 A custom-formed mantel shield.

To protect a mantel from the heat of an Intrepid II in a
fireplace installation, the ventilated mantel shield must
be at least 48” (1220 mm) long, and it must be centered
over the stove. Ventilated shields for side trim must
extend the full length of the trim.

An unprotected mantel (‘A’, Fig. 15) cannot be more
than 9” (230 mm) deep and must have a minimum
clearance of 30” (760 mm), measured from the stove’s
top plate. With a ventilated shield, this clearance may
be reduced safely to 14” (360 mm).

Unprotected top trim (B) protruding 2” (50mm) or less
from the face of the fireplace must be a minimum of 24”
(610 mm) from the stove’s top surface. With a venti­lated trim shield, this clearance may be reduced safely
to 14” (360 mm).

Unprotected side trim (C) that protrudes 2” (50mm) or
less from the face of a fireplace must have a minimum
clearance of 15” (380mm), measured from the stove’s
top side edge. With a ventilated trim shield, the clear­ance may be reduced safely to 10” (254 mm). If the trim
extends more than 2” (51 mm), wall clearance require­ments apply.

Assembly

Clean the Griddle Before Use

At the factory the griddle is coated with vegetable oil to
prevent rusting while the stove is in transit and storage.
Remove the oil with a dry rag or paper towel before you
use the stove.

Set Up the Stove

Remove any loose parts from inside the stove. Place a
protective pad on the floor, arrange some sections of 4
x 4 lumber on the pad for support, and carefully tip the
stove onto them, on its back.

Remove and discard the four large slot-head screws
from the stove bottom (Fig. 27) and install the stove
legs, using the hex head bolts from the parts bag. Use
3/8” washers with three of the legs; the door/damper
handle holder installs in place of a washer on the right
front leg. Position the holder so the hole to accept the
handle nub faces out from the right side of the stove.
Tighten the bolts firmly.

ST512

Fig. 28 Attach bottom heat shield.

Storing the Handle

Use the removable handle to open or close the front
doors, or to change the position of the damper. After
using it, remove it so it won’t get hot, and store it in the
handle holder installed behind the right front leg. (Fig.

29)

A bottom heat shield must be used unless the stove is
to be situated on a completely noncombustible hearth,
such as unpainted concrete over earth. To install the
bottom heat shield, loosen the leg bolts, and slip the
bottom heat shield C-clips onto the bolts. Attach the
bottom heat shield to the C-clips with the wing nuts, and
tighten the leg bolts. Align the shield as shown in Figure

Install the handle on the griddle. Place the griddle
upside down at the edge of a flat surface and assemble
the handle as shown. (Fig. 31)

With the handle pointing 45° from its final position,
tighten the nut as far as possible with pliers. Move the
handle to its final position while still holding the nut with
the pliers. Take care not to overtighten, as tab may
snap.

Operation

Your Intrepid II’s Controls and

What They Do

The stove has two controls to regulate performance: a

primary air control supplies oxygen for the fire, and a
damper directs air flow within the stove to activate and

deactivate the catalytic combustor.

Additional air for catalytic combustion is regulated auto­matically, and does not require operator control.

Symbols cast into the stove are reminders of the correct
directions for opening and closing the controls. In these
directions, ‘left’ and ‘right’ assume that you are facing
the front of the stove.

A Single Air Control Regulates the

Amount of Heat the Fire Will Produce and

How Long it Will Burn

The primary air control lever, located at the right rear
corner of the stove, controls the amount of incoming air
for starting, maintaining, and reviving a fire. More air
entering the stove makes the fire burn hotter and faster,
while less air prolongs the burn at a lower heat level.

For the greatest air supply and maximum heat output
(but the shortest burn time), move the lever to the left.
For a fire that will last longer with less heat, move the
lever to the right. You can set the lever anywhere in
between the left and right extremes. (Fig. 33)

The Intrepid II features an automatic thermostat to en­sure an even heat output at any setting you select. The
thermostat senses the heating and cooling of the stove
surface and adjusts the air shutter accordingly.

A Damper Directs Air Flow

Within the Stove

The damper handle opens and closes the damper to
direct air flow within the stove, and is next to, and to the
right of, the primary air control lever on the right side of
the stove. (Fig. 34)

When the handle points to the floor, the damper is
open, letting smoke pass directly into the chimney. The
damper must be open when starting or reviving a fire,
and whenever the griddle or doors are opened.

When the handle points to the front, the damper is
closed. Smoke from the fire travels through the catalytic
combustion system where it can burn further for greater
efficiency, before passing up the chimney.

The damper has no intermediate positions. Figure 28
shows the handle’s open and closed positions.

When closing the damper, push firmly and snap it
into the locked position to ensure that the stove
remains in the catalytic mode.

(Updraft Mode)

Andirons

Your stove has andirons to keep logs away from the
glass panels. The andirons are important to maintain
clear fireviewing and should be removed only while
reloading through the front doors.

Wear heavy stove gloves when removing the andirons,
and place them on a noncombustible surface until you
replace them in the stove. Most stove owners will prefer
the convenience of top loading through the griddle, and
will leave the andirons in place permanently.

Fig. 35 Remove the andirons for front loading.

Closed

(Catalytic Mode)

Fig. 34 The damper is either open or closed. There are no
intermediate positions.

ST519

Glass Door Panels

The glass panels in the doors have a heat-reflective
coating on the outside surface. Heat reflected back to
the inside of the glass helps keep the inner surface at
a higher temperature than the outside. In combination
with pre-heated primary combustion air ‘washing’ over
the inside of the glass, this helps provide clear fire­viewing at most operating levels.

Two Ways to Add Fuel

The Intrepid II’s griddle lifts for convenient top-loading
of logs, and is the easiest way of regularly adding fuel.
However, the front doors open as well for adding an oc­casional log to a fire. (Fig. 36)

You can open (or even remove) the front doors and
place the optional Intrepid II spark screen in the front
opening for open-fire viewing.

ST521

Fig. 36 Top loading is the best way to add fuel during regular
use. Front loading is useful for kindling a fire.

Intrepid II Woodburning Stove

WARNING: For safety and greatest efficiency, oper­ate your stove only with all doors/griddles fully
closed. The test standard for your stove when it is
operated in this mode is UL 1482.

Your stove may be used as a fireplace with the front
doors open or removed only when the spark screen
is placed correctly in the opening to protect against
the possibility of sparks and embers leaving your
stove. The test standard for your stove when it is
operated in this mode is UL 737.

Use only the Intrepid II spark screen, part #0136,
with your Intrepid II.

Intrepid II spark screens are available from your
Vermont Castings’ Authorized Dealer.

To open the front doors, insert the handle into the door
latch stub and turn it to the left and up. To close them,
always close the left door first. Turn the handle in the
right door to the left and up (to the open position) and
close the door. Push on the door as you turn the handle
to the right and down. The doors will draw in slightly,
and the handle should offer some resistance as you
turn it to the closed position. (Fig. 37)

Avoid striking the glass or slamming the doors to re­duce the risk of breaking the glass.

When you’re not using the door handle, store it in the
holder behind the right front leg of the stove.

Open
Position

Closed
Position

For areas that do not have a supply of hardwood, com­monly burned softwoods include tamarack, yellow pine,
white pine, Eastern red cedar, fir, and redwood. These
too should be properly dried.

Store firewood under cover to keep it dry. Dry, well-sea
soned wood is best for heating and fire-viewing. How­ever, avoid wood dried more than two years. This wood
burns very quickly, reducing burn time.

Even for short-term storage, keep wood a safe distance
from the heater and keep it out of the areas around the
heater used for refueling and ash removal.

A Surface Thermometer is a Valuable

Guide to Operation

An optional surface thermometer tells you when to
adjust the air control, when to refuel, and helps to tell
when your catalyst is operating properly.

For example, when the thermometer registers at least
450°F (230°C) after start-up you know the stove is hot
enough to begin catalytic combustion and it may be
time to close the damper.

Place the thermometer in the center of the griddle, as in
Figure 38, and use the following temperature ranges as
a guide to operation:

When thermometer readings drop below 350°F (175°C)
it’s time to adjust the air control for a higher burn rate or
to reload the stove.

• A temperature reading over 750°F (400°C) is a sign

to cut back on the air supply to slow the burn rate.

• Readings in the 300-400°F (150-200°C) range indi-

cate low to medium heat output.

• Readings of 500-650°F (260-340°C) indicate high

heat output. Operating your Intrepid II continuously
at griddle temperatures of 750°F (400°C) or higher
may damage inner parts or the enamel finish.

Burn Only High-Quality Wood

The Intrepid II is designed to burn natural wood only; do
not burn fuels other than that for which it was designed.

You’ll enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned. The wood
should be 16” (410mm) in length.

The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and air­dried outside under cover for at least one year.

Intrepid II Woodburning Stove

Use the Air Control Settings

that Work Best for You

No single air control setting will fit every situation. Set­tings will differ depending on the quality of the fuel, the
amount of heat desired, and how long you wish the fire
to burn.

The control setting also depends on your particular
installation’s “draft,” or the force that moves air from the
stove up through the chimney. Draft is affected by such
things as the length, type, and location of the chimney,
local geography, nearby obstructions, and other factors.

Too much draft may cause excessive temperatures in
the Intrepid II, and could even damage the combustor.
On the other hand, too little draft can cause backpuffing
into the room and/or the “plugging” of the chimney or
combustor.

How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrol­lable burn or a glowing-red stove part. A sign of inad­equate draft is smoke leaking into the room through the
stove or chimney connector joints, low heat, and dirty
glass.

In some newer homes that are well-insulated and
weather-tight, poor draft may result from insufficient air
in the house. In such instances, an open window near
the stove on the windward side of the house will provide
the fresh air needed.

Another option for getting more combustion air to the
stove is to duct air directly from outdoors to the stove.
In fact, in some areas provisions for outside combustion
air are required in all new construction.

Your Intrepid II will accept a duct carrying outside air for
combustion.

When first using the stove, keep track of the air control
settings. You will quickly find that a specific setting will
give you a fixed amount of heat. It may take some time
to determine the amount of heat and the length of burn
you should expect from various settings. Please read
the Draft Management section beginning on Page 25
for more information on how installation features affect
draft.

Most installations do not require a large amount of com­bustion air, especially if adequate draft is available.

Do not for any reason attempt to increase the firing
of your heater by altering the air control adjustment
range outlined in these directions.

Use the following air control settings as a starting point
to help determine the best settings for your installation.
Each is described as a fraction of the total distance the
lever may be moved from right to left.

Intrepid II Control Settings

Burn Rate Primary Air Control

Low From far right to 1/3 the
distance to left

Medium From 1/3 to 2/3
the distance to left
High From 2/3 the distance

Before you start using the stove, please read the Draft
Management section starting on Page 25 to see how
the features of your installation will affect the stove’s
performance. You and the stove are parts of a system,
and other parts of the system have a strong effect on
operation; you may need to vary your firing technique to
get the performance you want.

How to Build a Wood Fire

and Keep it Going

An Intrepid II leaves the factory with the combustor
installed.

In the United States, it is against the law to operate this
wood heater in a manner inconsistent with operating
instructions in this manual, or if the catalytic combustor
is deactivated or removed.

High-Efficiency Wood Burning

with Catalytic Combustion

The catalytic combustion system in your Intrepid II
produces the best conditions for secondary combustion.

When the stove damper is closed, smoke goes through
the catalytic element, burning at temperatures of
500-600°F (260-315°C), half the temperature normally
needed for unaided secondary combustion.

The catalytic element is a ceramic “honeycomb” coated
with a noble metal, usually platinum. The element is in
the secondary combustion chamber, made of a spe­cial high-temperature insulating refractory material.
The chamber provides the correct environment neces­sary for secondary combustion of the fuel (smoke).

Closing the damper may also reduce draft. Closing the
damper too soon may put out the fire or deactivate the
combustor. Close the damper only when the fire is well
established. When starting a fire, wait until there is an
ember bed of at least 3-4” (76-102mm) before closing
the damper.

Never kindle a fire with colored paper or paper that
has colored ink or a glossy surface, and never burn
treated wood, garbage, solvents, or trash. All of these
may poison the catalyst and prevent it from operating
properly. Never burn cardboard or loose paper except
for kindling purposes. Never burn coal; doing so can

22

2000966

produce soot or large flakes of char or fly ash that can
coat the combustor and cause smoke to spill into the
room. Coal smoke also can poison the catalyst so that it
won’t operate properly.

In general, the fire must be sufficiently well-established
to ensure catalytic activity is initiated. When first starting
a fire, maintain a medium- to high- firing rate for at least
twenty minutes. This ensures the stove, catalyst, and
fuel are all stabilized at the proper operating tempera­tures. This may be long enough to warm the chimney
well enough to support a good draft; some installations
may need more time. Please read the Draft Manage­ment information starting on Page 25 to see if your
installation has features that may require more time to
warm up.

Even though it is possible for the fire to get quite hot
within a few minutes, the combustor may stop working
or the fire may go out if the fire is allowed to die down
immediately as a result of closing the damper. Once the
combustor starts working, heat generated by burning
the smoke will keep it working.

To determine whether the combustor is operating, ob­serve the amount of smoke leaving the chimney when
the damper is activated and when it is not. This proce­dure is described on Page 29.

Conditioning Your Stove

Cast iron is extremely strong, but it can be broken with
a sharp blow from a hammer or from the thermal shock
of rapid and extreme temperature change.

The cast plates expand and contract with changes in
temperature. When you first begin using your Intrepid II,
minimize thermal stress by allowing the plates to adjust
gradually during three or four initial break-in fires follow­ing Steps 1-3 below.

Starting and Maintaining a Wood Fire

Burn solid wood fuel only in the Intrepid II, and burn it
directly on the grate. Do not elevate the fuel. Do not
burn coal or other fuels.

The damper must be open when starting a fire or
when refueling.

1. Open the stove damper, and open the primary air
control fully.

2. Place several sheets of crumpled newspaper in the
stove. Do NOT use glossy advertisements or colored
paper, as they can poison the catalyst. Place on the
paper six or eight pieces of dry kindling split to a
finger-width size, and on the kindling lay two or three
larger sticks of split dry wood approximately 1-2”
(25-50mm) in diameter. (Fig. 39)

Intrepid II Woodburning Stove

ST263

Fig. 39 Start the fire with newspaper and dry kindling.

DO NOT USE CHEMICALS OR FLUIDS TO START
THE FIRE. DO NOT BURN GARBAGE OR FLAMMA­BLE FLUIDS SUCH AS GASOLINE, NAPHTHA, OR
ENGINE OIL. Also, never use gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen up” a fire. Keep all such
liquids well away from the Intrepid II while it is in
use.

3. Light the newspaper and close the door. Gradu­ally build up the fire by adding a few 3-5” (76-127
mm) diameter splits. If this is one of the first few

“break-in” fires, let the fire burn brightly, and
then let it die out.

During the break-in fires, don’t let the stove get hotter
than 500°F (260°C) as measured on an optional stove­top thermometer. Adjust the air control lever as neces­sary to control the fire. Some odor from the stove’s hot
metal, the paint, and the cement is normal for the first
few fires.

NOTE: Some chimneys need to be “primed,” or
warmed up, before they will draw sufficiently to start
a fire. To correct this situation, roll up a couple pieces
of newspaper, place them on top of the kindling and
toward the back of the stove, light them, and close the
doors. This should heat the chimney enough to initiate
a draft.

Once the draft is established, open the front door and
light the rest of the fuel from the bottom. Do not light the
main bed of fuel until the chimney begins drawing, and
repeat the procedure as often as necessary if the initial
attempt is unsuccessful.

4. If your Intrepid II has been broken-in previously
using Steps 1-3, continue to build the fire gradually.
Add larger wood with a diameter of 3-4” (76-102
mm). (Fig. 40)

2000966

23

Intrepid II Woodburning Stove

ST264

Fig. 40 Add larger pieces of wood as the fire begins to burn
well.

Continue adding split logs of this size to the briskly-

burning fire until there is a glowing ember bed at
least 3” (75mm) deep. A good ember bed is neces­sary for proper functioning of the catalytic system
and may take an hour or more to establish.

5. Close the damper when the griddle temperature
reaches 450° F (230°C).

6. Adjust the air control for your desired heat output.

Refuel While the Embers are Still Hot

Reload the Intrepid II while it is still hot and there are
plenty of glowing embers to re-kindle the fire. Include
some smaller pieces of wood in the new load of fuel to
help the stove rebuild its operating temperature quickly.

Wear stove gloves, and follow this procedure when you
reload your stove:

1. Open the thermostat lever.

2. Open the damper.

3. Check the ash level in the ash pan; empty, if neces
sary, and replace the pan.

4. Open the griddle.

5. Position the charcoal in the middle of the firebox
(Fig. 41)then load wood — smaller, split pieces first.
Increase the amount of fuel you load into the stove
as you become familiar with your stove and the
heating needs of your home.

NOTE: If the remaining charcoal bed is relatively thick
and if your fuel is well seasoned, it is possible to add
fresh fuel (smaller pieces first), close the door and
damper, and reset the primary air thermostat for the
desired heat output.

Do not break the charcoal into very small pieces or
pound or compress the charcoal bed.

It is important that air can circulate under the wood for
the fire to be quickly revived.

WARNING: Operate your Intrepid II only with the
doors either fully open or fully closed.

-

ST264a

Fig. 41 Add full size logs when the ember bed is 3” (75mm)
deep.

CAUTION: The Intrepid II will be hot while in opera­tion. Keep children, clothing and furniture away.
Contact may cause skin burns.

DO NOT OVERFIRE THIS HEATER. Overfiring may

cause a house fire, or can result in permanent damage
to the stove and to the catalytic combustor. If any part
of the Intrepid II glows, you are overfiring.

Ash Disposal

Remove ash before it reaches the top of the ash pan.
Check the level at least once a day, and before each
re-fueling. If the ash is close to the top edge of the pan,
empty it according to this procedure:

1. Open the damper.

2. Open the front doors fully.

3. Using stove gloves, pull the ash pan out of the stove
by its handle.

4. Remove the ash pan and properly dispose of the
ashes. Be sure to keep the pan level during dispos­al.

5. Return the ash pan to the stove.

Empty the ash pan regularly, typically every one to
three days. The frequency will vary depending on how
you operate your Intrepid II; if you burn more wood at
higher heat output settings, ash will accumulate rapidly.

Remove ash frequently and place it outdoors in a metal
container with a tight-fitting lid. Put the closed container
of ash on a noncombustible floor or on the ground,
well away from all combustible materials, pending final
disposal. If the ash is disposed of by burial in soil or
otherwise locally dispersed, keep it in the closed con­tainer until all cinders have thoroughly cooled. You can
use wood ash as a garden fertilizer.

CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the stove; always remove
and dispose of the ash properly.

Draft Management

A stove is part of a system, which includes the chimney,
the operator, the fuel, and the home. The other parts of
the system will affect how well the stove works. When
there is a good match between all the parts, the system
works well.

Wood stove operation depends on natural (unforced)
draft. Natural draft occurs when the smoke is hotter
(and therefore lighter) than the outdoor air at the top of
the chimney. The bigger the temperature difference, the
stronger the draft. As the smoke rises from the chimney
it provides suction or ‘draw’ that pulls air into the stove
for combustion. A slow, lazy fire with the stove’s air inlet
fully open indicates a weak draft. A brisk fire, supported
only by air entering the stove through the normal inlet,
indicates a good draft. The stove’s air inlet is passive;
it regulates how much air can enter the stove, but it
doesn’t move air into it.

Depending on the features of your installation - steel or
masonry chimney, inside or outside the house, matched
to the stove’s outlet or oversized - your system may
warm up quickly, or it may take a while to warm up and
operate well. With an ‘airtight’ stove, one which restricts
the amount of air getting into the firebox, the chimney
must keep the smoke warm all the way to the outdoors.
Some chimneys do this better than others. Here’s a list
of features and their effects.

Masonry Chimney

Masonry is a traditional material for chimneys, but it
can perform poorly when it serves an ‘airtight’ stove.
Masonry is a very effective ‘heat sink’ - it absorbs a lot
of heat. It can cool the smoke enough to diminish draft.
The bigger the chimney, the longer it takes to warm up.
It’s often very difficult to warm up an outdoor masonry
chimney, especially an oversized one, and keep it warm
enough to maintain an adequate draft.

Steel Chimney

Most factory-made steel chimneys have a layer of in­sulation around the inner flue. This insulation keeps the
smoke warm. The insulation is less dense than mason­ry, so the inner steel liner warms up more quickly than a
masonry chimney. Steel doesn’t have the good looks of
masonry, but it performs much better.

Indoor/Outdoor location

Because the chimney must keep the smoke warm, it’s
best to locate it inside the house. This uses the house
as insulation for the flue and allows a little heat release
into the home. An indoor chimney won’t lose its heat to
the outdoors, so it takes less heat from the stove to get
it warm and keep it warm.

Intrepid II Woodburning Stove

Flue sizing

The inside size of a chimney for an ‘airtight’ stove
should match the size of the stove’s flue outlet. When
a chimney serves an airtight, more is not better; in fact,
it can be a disadvantage. Hot gases cool off through
expansion; if we vent a stove with a six-inch flue collar
(28 square inch area) into a 10 x 10” flue, the gases
expand to over three times their original size. This cools
the gases, which weakens draft strength. If an over­sized flue is also outside the house, the heat it absorbs
gets transferred to the outdoor air and the flue usually
stays cool.

It’s common for a masonry flue, especially one built for
a fireplace, to be oversized for an airtight stove. It can
take quite a while to warm up such a flue, and the re­sults can be disappointing. The best solution to an over­sized flue is an insulated steel chimney liner, the same
diameter as the stove or insert’s flue outlet; the liner
keeps the smoke at its original volume, and the result is
a stronger draft. An uninsulated liner is a second choice

- the liner keeps the smoke restricted to its original size,
but the smoke still must warm up the air around the
liner. This makes the warm-up process take longer.

Pipe & Chimney Layout

Every turn the smoke must take in its travel from the
stove to the chimney top will slow it down. The ideal
pipe and chimney layout is straight up from the stove,
to a completely straight chimney. If you’re starting
from scratch, use this layout if possible. If the stove­pipe must elbow to enter a chimney, locate the thimble
about midway between the stove top and the ceiling.
This achieves several goals: it lets the smoke speed up
before it must turn, it leaves some pipe in the room for
heat transfer, and it gives you long-term flexibility for
installing a taller stove without relocating the thimble.

There should be no more than eight feet of single-wall
stove pipe between the stove and a chimney; longer
runs can cool the smoke enough to cause draft and
creosote problems. Use double-wall stove pipe for long
runs.

Single Venting

Each ‘airtight’ stove requires its own flue. If an airtight
stove is vented to a flue that also serves an open fire­place, or a leakier stove, it’s easier for the chimney draft
to pull air in through those channels than it is to pull air
through the airtight, and performance suffers. Imagine
a vacuum cleaner with a hole in the hose to see the ef­fect here. In some cases the other appliance can even
cause a negative draft through the airtight, and result in
a dangerous draft reversal.

2000966

25

Intrepid II Woodburning Stove

Creosote

Creosote is a by-product of slow wood-burning. It’s an
organic tar that can condense in the flue if it’s dense
in the smoke, and slow-moving, and cools off to less
than 290°F. Condensed creosote is volatile, and can
generate chimney fires if it gets hot enough. All the
features that affect chimney draft also affect creosote
condensation - so use whatever combination of installa­tion features and operational steps will encourage good
draft and minimize creosote production.

Because letting the smoke cool off and slow down is
one of the keys to creosote production, it makes sense
to line a chimney to match the stove’s outlet size, for
safety reasons as well as performance. Canadian law
requires a matching liner to serve any stove or insert
vented through a fireplace chimney; in the US, the
National Fire Protection Association recommends one if
the flue is more than three times bigger (in square area)
than the outlet on the stove or insert. Some localities
enforce the NFPA guidelines as part of their building
codes.

Fuel

Even the best stove installation will not perform well
with poor fuel. The best fuel is hardwood that has air­dried 12-18 months. Softwood burns, but not as long as
hardwood. Fairly ‘green’ wood has a good amount of
moisture in it; it will burn, but some of the heat potential
is used to drive the remaining moisture off the wood.
This reduces the amount that reaches your home and
can contribute to a creosote problem. There are mois­ture meters available for firewood; you can also judge
your wood by its appearance and weight. If you get it
green, lift a piece and get a sense of its weight; it can
lose a third or more of its weight as it dries. Also look at
the ends of a log; as it dries it shrinks and often cracks.
The more weathered and cracked a piece is, the drier
it is.

Dry wood burns readily with a good chimney draft. But
with modern stoves, especially catalytic ones, the wood
can be too dry. While extra-dry wood has little creosote
in it, the remainder can ‘gas out’ from the wood quickly
and densely enough to overload the catalytic burner.
If you hear a rumbling or roaring noise, like a propane
torch, from the stove, that is a sign that the catalyst is
seriously overfiring. The catalyst is a platinum film on a
ceramic base; the metal can get to higher temperatures
than the ceramic can take, and overfiring the catalyst
can break it. Dry wood can also burn out faster than
you want. If your dry wood burns out too quickly or
overloads the catalyst you can mix in greener wood to
slow the fire down.

Back-puffing

Back-puffing results when the fire produces volatile
gases faster than the chimney draft pulls them out of
the firebox. The gases back up in the firebox till they’re
dense enough and hot enough to ignite. If your stove
back-puffs, you should open up the damper to let the
smoke rise to the flue more quickly, let more air into
the firebox, and avoid big loads of firewood. Run your
stove with enough primary air so that you always see
lively, dancing flames in the firebox; a lazy, smoky fire is
inefficient and can contribute to creosote buildup in the
chimney.

Draft Testing

An easy way to test your chimney draft is to close the
stove’s damper, wait a few minutes to let the airflow
stabilize, then see whether you can vary the strength of
the fire by swinging the air control open and closed. Re­sults are not always instant; you may need to wait a few
minutes for a change in the air control setting to have
an effect on the fire. If there’s no change, then the draft
isn’t strong enough yet to let you close the damper, and
you’ll need to open it for a while longer and manage the
fire with the air inlet until the draft strengthens. If you
keep track of your burning habits and relate them to
their effects on the stove’s operation, you’ll be rewarded
with good performance and a safe system.

Negative Pressure

Good draft also depends on a supply of air to the stove;
a chimney can’t pull in more air than is available to it.
Sluggish draft results when a house is tight enough to
prevent the ready flow of air to the stove, or by competi­tion between the stove and other equipment that sends
indoor air outside - especially power-driven equipment
like range hoods, clothes dryers, etc. If the chimney
draws well with all other equipment turned off (or
sealed, in the case of fireplaces and/or other stoves),
then you simply need to be careful with timing the use
of the other equipment. If you need to crack a nearby
window or door to enable the chimney to draw well,
that’s a sign that you should install an outside-air intake
to bring combustion air directly to the stove. Vermont
Castings dealers carry adapters to attach to the stove
to connect an air duct for outdoor combustion air.

Conclusion

Wood-burning is an art rather than a science. Once the
stove and chimney system are in place, the stove user
can only vary technique, mostly your timing, to achieve
good results. If you keep track of your burning habits
and relate them to their effects on the stove’s operation,
you’ll be rewarded with good performance and a safe
system.

Maintenance

Intrepid II Woodburning Stove

Let the fire in the stove go out and allow the stove to
cool completely before beginning any maintenance
procedure.

Care of the Cast Iron Surface

An occasional dusting with a dry rag will keep the
painted cast iron of your Intrepid looking new.
The stove’s paint can be touched up as needed. First,
clean the areas to be painted with a wire brush. Then,
touch up the stove with high temperature stove paint.
Apply the paint sparingly, and keep in mind that two
light coats of paint are better than a single heavy one.

Care of Porcelain Enamel Finish

Use a dry or slightly damp rag or a soft brush to remove
spills or stains. For difficult jobs that require a cleaning
agent, use only a kitchen appliance cleaner or polish
recommended for use on enamel surfaces.

Cleaning the Glass

Most of the carbon deposits on the glass will burn off
during hot fires. However, the ash residue that accumu­lates on the glass surface should be removed regularly
to prevent etching. Follow this procedure to clean the
glass:

• Be sure the glass is completely cool.

• Clean the glass with water or a cleaner made

especially for this purpose. Do not use abrasive
cleaners.

• Rinse the glass thoroughly.

• Dry the glass completely.

Glass Replacement

Replace glass only with Part no. 140-1156 right side
and 140-1157 left side glass panels. The glass panel
rests on a cushion provided by a rope gasket part no
1203556, and is held in place by clips. (Fig. 42) The
glass is IR coated on one side which is marked “THIS
SIDE OUT”.

1. Remove the door from the stove and place it on a
sturdy, level work surface. Use a towel to protect
the porcelain enamel finish.

2. Remove the retainer clips. (Two phillips head
screws on each clip.)

3. Inspect the gasket. If the window gasket is in good
condition, you can leave it in place. If you replace
it, use only Part No. 1203556. Be sure the channel
around the window opening is clean, and free of
dust.

4. Install the glass. Lay the glass on the inner gasket
with the coated side down (toward the outside of
the door). Tighten the screws snugly, but loose
enough to allow for a little movement of the glass
when the stove is in operation. Overtightening can
crack the glass immediately or cause it to crack if it
is unable to expand when hot.

Check the Operation of the

Primary Air Shutter

The primary air shutter is visible from the back of the
stove. The shutter must open and close freely when
you move the thermostat lever. If it does not, check for
any obstruction, or for a bound or stretched chain need­ing adjustment. (Fig. 43)

On a cold stove the shutter should be open no more
than 1/8” (3mm) when the primary air control lever is
pushed completely to the left (closed), as seen from the
back of the stove. When the lever is pushed completely
to the right (open), the shutter should be open to an
angle of approximately 70° from the stove back.

The ball chain should measure 8¹⁄₂” (216mm) from
connection to the thermostat coil to connection on the
primary air flap.

If setting is incorrect, the thermostat coil may be bent or
broken. Call your Vermont Castings Dealer for assis­tance.

How to Adjust the Door Latch

Over time, the gasketing around the doors will com­press, and the latch may need adjustment. To adjust
the latch, loosen the small locking nut, extend the
striker screw one turn while keeping the striker screw
from turning. (Fig. 44) Keep making adjustments a little
at a time until the setting is right.

The front doors of the stove should close securely and
tightly, when the handle is in the closed position. When
the latch is properly adjusted there should be a slight
resistance as the doors are moved to the completely
closed position.

Tighten the Damper Handle as Needed

The damper handle is attached to the damper rod
with a set screw bearing against a flat spot on the rod.
Check the set screw periodically for tightness; tighten
as needed.

Damper Adjustment

When the stove damper is closed, the pressure of the
rod against the damper plate assures a good seal be­tween the damper and the damper housing. Adjustment
may be needed after a period of time to retain adequate
pressure.

To make this adjustment, start with the damper in the
closed and locked position. (Fig. 45) Loosen the 7/16”
locking nut in the center of the damper. Use a 1/8” Allen
wrench to turn the Allen screw a full turn clockwise. Test
the damper for snugness, and continue adjusting the
Allen screw as needed. Tighten the 7/16” locking nut
when the damper operates smoothly but firmly.

Intrepid II Woodburning Stove

The Catalytic Combustion System

Inspection and Cleaning

This wood heater includes a catalytic combustor, which
needs periodic inspection and replacement for proper
operation. In the United States, it is against the law to
operate this wood heater in a manner inconsistent with
the operating instructions in this manual, or if the cata­lytic element is deactivated or removed.

Under normal operating conditions the catalytic element
should remain active for two to six years (depending on
the amount of wood burned). However, it is important
to monitor the combustor periodically to ensure that it
is functioning properly as well as to determine when it
needs to be replaced.

A probe thermostat, passing through the back of the
stove into the catalytic combustion chamber, automati
cally regulates the catalytic combustion air supply.
Deterioration of the probe may result in decreased
catalytic combustor performance.

A poorly-functioning catalytic combustion system will
result in a loss of heating efficiency, and an increase in
creosote and emissions.

The combustor should be visually inspected in place for
fly ash accumulation and physical damage three times
per year. Do not remove the combustor unless a more
detailed inspection is warranted because of diminished
performance as outlined below, or to inspect the probe
thermostat.

The refractory package that houses the catalytic com­bustor should be inspected annually for a buildup of flay
ash, and cleaned if necessary. This may be done during
examination of the combustor.

The probe thermostat should be inspected annually, or
more often if decreased catalytic combustion perfor­mance is not due to a defective combustor.

-

When to Suspect a Combustion

System Problem

The best way to evaluate the performance of your In­trepid II’s combustion system is to watch the amount of
smoke leaving the chimney - both when the combustor
has achieved “light-off” and when it has not. Follow this
procedure:

With a fire going and the combustor activated, with the
damper closed to send smoke through the combustor
as described in the Operation Section, go outside and
watch the smoke leaving the chimney.

Then, open the stove damper and again watch the
smoke leaving the chimney.

You should see significantly more smoke after the sec
ond step, when the stove damper is open and smoke
does not go through the combustor. However, do not
confuse smoke with steam form wet wood; steam dis­appears rapidly in the air, smoke does not.

If this test indicates a problem, consider other possible
factors as well, such as the time of year or a change
in the quality of your fuel. In spring and fall, draft is
weaker than it is during colder winter weather, and fires
can burn sluggishly. Small, hot fires are a good solution
under these conditions.

“Green” (insufficiently seasoned) wood will burn more
poorly than properly seasoned fuel. You may have to
run your stove hotter (with more primary air) to achieve
good performance if you are burning green or wet
wood.

Also, consider any changes in your burning routine.

Once you have ruled out any other possible causes for
decline in performance, you may inspect the combus­tor and probe. Wear a dust mask, safety glasses, and
gloves. Refer to Figure 46 as a guide.

1. Remove the andirons.

2. Reach inside the stove with a pair of pliers and turn

the two clamps that hold the fireback 90°. Turn the
left clamp clockwise, and the right clamp counter­clockwise.

3. Grasp the fireback by its vertical ribs and remove it,

together with the attached throat hood. Pull the left
side out first.

4. Carefully clean the left and right exhaust pockets of

the refractory package. Use a shop vacuum, ideally
one with a very fine filter, and be careful to avoid
damaging the refractory material. This material can
stand high temperatures, but it is somewhat brittle
physically.

5. Carefully remove the refractory access panel in front

of the catalytic element.

6. Gently slide the catalytic element out of the refrac

tory chamber. Check the element and the bottom of
the chamber for a buildup of fly ash.

7. If the catalytic element is clogged, take it outdoors

for cleaning. Blow gently through the honeycomb. A
large amount of fly ash may come out of the ele
ment.

8. Inspect the element. Although small hairline cracks

will not affect performance, the element should be
largely intact. If the element is broken in pieces or
has large sections missing, replace it. Call your
dealer for a replacement element, part no. 160-

2521.

9. Use a flashlight and a mirror, inserted into one of
the exhaust pockets of the refractory chamber, to in­spect the probe. The end of the probe should extend
about 1” into the combustion chamber, and should
not show any signs of deterioration.

Use the stove in your usual manner for two weeks,
inspecting the chimney and the chimney connector
frequently.

If creosote does not build up as quickly as before, it is
likely that the performance change was caused by fly
ash deposits on the catalytic element. However, moni­tor the chimney system for a few weeks to ensure that
proper performance continues.

If you continue to find a significant creosote buildup or if
you continue to see excessive smoke from the chimney,
the catalytic element will need to be replaced. Call your
dealer for information about a replacement.

NOTE: Use only replacement catalyst, part no. 160-

2521.

Replace Refractory Package

Refer to Figure 46.

1. Remove andirons.

2. Reach inside the stove with pair of pliers and turn
the two clamps that hold the fireback 90°. Turn the
let clamp clockwise and the right clamp counter­clockwise. The bolts that hold these clamps are
tapped into the back as well as capped by chrome
acorn nuts in the back.

3. Grasp the upper fireback by its vertical ribs and re
move it, together with the attached throat hood. Pull
the left side out first.

4. Carefully remove the refractory access panel in front
of the catalytic block.

5. Gently slide the catalytic block out of the refractory
chamber.

6. Remove the damper housing. It is held in place by
two weld screws and two chrome acorn nuts in the
back of the stove. Loosen the chrome acorn nuts
and rotate the tabs to release the damper housing.
You may find it necessary to remove or loosen the
thermostat cover to access the one of acorn nuts
installed behind the cover.

7. Remove the rear airtube in the back of the stove
which is held in place with two phillips screws.

8. Take out the secondary probe by removing the upper
phillips screw and sliding the probe out of the hole.

9. Lift the damaged refractory chamber up and out of
the firebox.

10. Reverse the procedure for installing the new refrac­tory chamber.

Replace the Stove Gaskets as Needed

The Intrepid uses fiberglass rope gaskets to make a
tight seal between some parts. With use, particularly on
those parts that move, gaskets can become brittle and
compressed, and can begin to lose their effectiveness.
These will need periodic replacement.

The sizes of replaceable gasket are listed below, along
with their applications.

Gasket Diameter ... And the Parts it Seals
5/16” wire gasket The griddle to the stove top
5/16” The damper to the upper fire
back; the front doors to the
stove front; and the door
halves to each other

There is a flat, die-cut gasket between each glass panel
and its door. See page 24 for information on replacing
the glass panel or its gasket.

If you need to change a gasket, first obtain an appropri
ate replacement from your Vermont Castings, Dealer.

Wait until the fire is out and the stove has cooled. Be
sure to follow the standard safety procedure for working
with dusty materials: Wear safety goggles and a dust
mask.

The procedure for replacing the gaskets is the same,
regardless of the gasket location.

1. Remove the existing gasket by grasping an end and
pulling firmly.

2. Use a wire brush or a screwdriver to clean the chan
nel of any remaining cement or bits of gasket. Re-

-

move stubborn deposits of cement with a cold chisel
if necessary.

3. Determine the correct length of the appropriate-sized
gasket by laying it out in the channel. Allow an extra
1-2” (25-50mm) and mark the spot to be cut.

4. Remove the gasket from the channel, place it on a
wood cutting surface, and cut it at the marked spot
with a utility knife. Twist the ends slightly to keep the
gasket from unraveling.

5. Lay an unbroken 1/8” (3mm) bead of gasket cement
in the newly-cleaned channel. Starting at one end,
press the gasket into the channel. Ensure a good
joint where the gasket meets before trimming any
excess. Do not overlap the gasket ends or leave
ends with ragged edges.

6. Press the gasketed part firmly against its normal
mating surface to seat the gasket evenly in its chan­nel.

7. For doors, replace the doors and close them on
a piece of waxed paper to keep the cement from
migrating onto the stove front, or tap other parts with
the rubber mallet (or hammer/block of wood).

8. Clean excess cement from around the channel. Let
the cement that holds the new gasket dry thoroughly.

Adjust the Door if Necessary

The door latch or damper mechanism may need adjust­ment after you have regasketed them. Initially, it may
require loosening to accommodate the new gasket; af­ter a few weeks, it may need tightening to compensate
for compression of the new gasket. The directions for
adjusting the latch and damper are on Page 27.

Permanent Gaskets

Other gaskets seal between non-moving parts, but
these are not subject to the same wear and deteriora­tion as gaskets on moving parts. It is unlikely that you
will ever need to replace these gaskets unless the
involved parts are disassembled and then put back
together. If this is the case, the job should be done only
by a qualified service technician. The diameter of the
gasket that seals these non-moving parts is 5/16”, and
the areas sealed are the flue collar to the stove back;
and the lower fireback to the sides. The glass panels
use a special die-cut flat gasket; refer to Page 24 for
information on these.

The Chimney System

Creosote

Your Intrepid II is designed to reduce creosote buildup
significantly. However, regular chimney inspection and
maintenance must still be performed. For safety, good
stove performance, and to protect your chimney and
chimney connector, inspect the chimney and chimney
connector on a regular schedule. Clean the system if
necessary. Failure to keep the chimney and connector
system clean can result in a serious chimney fire.

When wood is burned slowly, it produces tar, organic
vapors and moisture that combine to form creosote.
The creosote vapors condense in the relatively cool
chimney flue. As a result, creosote residue accumulates
on the flue lining. When ignited, this creosote makes an

extremely hot fire within the flue system that can dam
age the chimney and overheat adjacent combustible
material.

If you do have a chimney fire, act promptly to:

-

• Close the damper and thermostat lever.

• Get everyone out of the house.

• Call the Fire department.

You should inspect the system every two weeks during
the heating season as part of a regular maintenance
schedule. To inspect the chimney, let the stove cool
completely. Then, using a mirror and a strong light,
sight up through the flue collar into the chimney flue. If it
is not possible to inspect the flue system in this fashion
the stove must be disconnected to provide better view­ing access.

If a significant layer of creosote has accumulated - 1/8”
(3mm) or more - remove it to reduce the risk of a chim­ney fire.

Clean the chimney using a brush the same size and
shape as the flue liner. Flexible fiberglass rods are used
to run the brush up and down the liner, causing any
deposits to fall to the bottom of the chimney where they
can be removed through the clean out door.

The chimney connector should be cleaned by discon­necting the sections, taking them outside, and removing
any deposits with a stiff wire brush. Reinstall the con­nector sections after cleaning, being sure to secure the
individual sections with sheet metal screws.

If you cannot inspect or clean the chimney yourself,
contact your local Vermont Castings authorized dealer
or hire a professional chimney sweep.

Annual Maintenance

Perform a thorough cleaning, inspection and repair
each spring, at the end of the heating season.

• Thoroughly clean the chimney and chimney connec-

tor.

• Inspect the chimney for damage and deterioration.

Replace weak sections of prefabricated chimney.
Have a mason make repairs to a masonry chimney.

• Inspect the chimney connector and replace any

damaged sections.

• Check gasketing for wear or compression, and

replace if necessary. A ‘paper test’ will guide you on
this. Close and lock the door or damper on a slip of
paper and then try to pull the paper out. If the paper
pulls out with little or no resistance, the gasket is not
snug enough at that spot. If adjusting the damper or
latch does not result in a seal that makes it hard to
pull the paper out, replace the gasketing.

Intrepid II Woodburning Stove

• Inspect and clean the catalytic block, and vacuum

out the ash at the bottom of the back plate after
removing the lower fireback. Lightly clean the refrac­tory assembly that houses the element. Be careful
not to damage the refractory material, which is very
fragile.

• Inspect the secondary probe thermometer; refer to

Page 30.

• Check door and damper handles for tightness. Ad-

just if needed.

• Check heat shield screws. Tighten as necessary.

• Clean dust from the inner sides of bottom, rear and

connector heat shields.

• Remove ashes from the ash pan and replace with

moisture absorbing material (such as cat litter) to
keep the stove interior dry. Close the stove door to
keep cats from using the litter.

• Touch up the paint on black stoves.

Appendix: Catalytic Combustor

In any chemical reaction, including the combustion
process, there are certain conditions which must be
met before the reaction can take place. For example, a
reaction may require a certain temperature, or a certain
concentration of the reactants (the combustion gases
and oxygen), or a certain amount of time. Catalysts,
though not changed themselves during the reaction,
have the ability to act at a molecular level to change
these requirements. In the Intrepid II’s secondary
combustion chamber the catalyst reduces the tempera­ture at which secondary combustion can start from the
1000 - 1200°F (540 - 650°C) range to the 500 - 600°F
(260 - 315°C) range, increasing efficiency, and reducing
creosote and emissions.

The catalytic reaction, though advantageous, does
have some limitations of its own. Primary among these
it that the reactants (the gases) come into close physi­cal contact with the catalyst itself.

To ensure the necessary contact, the catalytic element
in your Intrepid II is composed of a ceramic base in the
shape of a honeycomb. On each of the honeycomb’s
many surfaces a coating of the catalyst (usually a
noble metal such as platinum or palladium) is applied.
The large surface area exposed in this configuration
ensures that the combustion gases have the greatest
opportunity to come in contact with the catalyst.

Loss of catalytic activity will be apparent in several
ways. First you may notice an increase in fuel con­sumption. Second, there will be a visible increase in the
rate at which creosote builds up in your chimney con­nector system. You may also notice a heavy discharge
of smoke from the chimney. A number of catalytic
problems which can cause loss of activity are described

below:

Blockage

While the honeycomb pattern ensures good contact, it
also increases the resistance to flow of the combustion
gases, and, because of the many surfaces, provides
more places for creosote and fly ash to deposit. It is
important to follow the operating instructions in order
to minimize these deposits, and to periodically inspect
your catalyst for signs of blockage.

Masking and Poisoning

While the catalyst itself does not enter into the combus­tion process, it is possible for certain elements, such
as lead and sulfur, to attach to the active sites on the
surface of the honeycomb. Though the catalyst is still
there, it is covered, or masked, by the contaminant, and
cannot function. To avoid this situation, it is important
not to burn anything in your Intrepid II that is a source
of these contaminants. Particularly avoid painted or
treated wood, coal, household trash, colored papers,
metal foils, or plastics. Chemical chimney cleaners may
also contain harmful elements. The safest approach is
to burn only untreated, natural wood.

Flame Impingement

The catalytic element is not designed for exposure to
direct flame. If you continually overfire your Intrepid
II, the chemistry of the catalyst coating may be altered,
inhibiting the combustion process. A glowing stove part
at the back of the firebox is a sign of over-firing.

Thermal degradation of the ceramic base may also oc­cur, causing the element to disintegrate. Stay within the

recommended guidelines of the Operation section.

Mechanical Damage

If the element is mishandled, damage may occur.
Always treat the element carefully. Remember the
catalyst is made of a ceramic material; treat it as you
would fine china. Hairline cracks will not affect the
performance of the catalyst, as long as the steel sleeve
holds the element in the proper position.

Peeling

Peeling of the surface coat may occur if the catalytic
element is frequently subjected to excessive tempera­tures. Follow the operating instructions carefully to
avoid this type of damage.

Every CFM Corporation product is equipped with either
a Corning “Long-Life”® or a Technical Glass Products
“Honeycomb”®. The products are equivalent. If for any
reason you must ship your catalytic element, remem­ber its fragile nature. Place the element in a plastic
bag, and package it with a generous amount of shock

absorbing material.

Exclusions & Limitations

1. This warranty is transferable; however, proof of original retail pur­chase is required.

2. This warranty does not cover misuse of the stove. Misuse includes
overfiring which will result if the stove is used in such a manner as
to cause one or more of the plates to glow red. Overfiring can be
identified later by warped plates and areas where the paint pigment
has burned off. Overfiring in enamel fireplaces is identified by bub­bling, cracking, chipping and discoloration of the porcelain enamel
finish. CFM Corporation offers no warranty on chipping of enamel
surfaces. Inspect your woodburning stove prior to accepting it for
any damage to the enamel.

3. This warranty does not cover misuse of the stove as described
in the Owner’s Guide, nor does it cover an stove which has been
modified unless authorized by a CFM Corporation representative in
writing. This warranty does not cover damage to the stove caused
by burning salt saturated wood, chemically treated wood, or any fuel
not recommended in the Owner’s Guide.

4. This warranty does not cover a stove repaired by someone other
than a Vermont Castings Authorized Dealer.

5. Damage to the unit while in transit is not covered by this warranty
but is subject to a claim against the common carrier. Contact
Vermont Castings Authorized Dealer from whom you purchased
your stove or CFM Corporation if the purchase was direct. (Do not
operate the stove as this may negate the ability to process the claim
with the carrier.)

6. Claims are not valid where the installation does not conform to local
building and fire codes or, in their absence, to the recommendations
in our Owner’s Guide.

7. The salt air environment of coastal areas, or a high-humidity en
vironment, can be corrosive to the porcelain enamel finish. These
conditions can cause rusting of the cast iron beneath the porcelain
enamel finish, which will cause the porcelain enamel finish to flake
off. This warranty does not cover damage caused by a salt air or
high-humidity environment.

8. CFM Corporation shall have no obligation to enhance or update any
unit once manufactured.

IN NO EVENT SHALL CFM CORPORATION BE LIABLE FOR INCI­DENTAL AND CONSEQUENTIAL DAMAGES. ALL IMPLIED WAR­RANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANT
ABILITY AND FITNESS, ARE LIMITED TO THE DURATION OF
THIS WRITTEN WARRANTY. THIS WARRANTY SUPERCEDES ALL
OTHER ORAL OR WRITTEN WARRANTIES.

Some states do not allow the exclusion or limitations of incidential and
consequential damages or limitations on how long an implied warranty
lasts, so the above limitations may not apply to you. This warranty gives
you specific rights and you may have other rights which vary from state
to state.

How to Obtain Service

If a defect is noted within the warranty period, the customer should
contact a Vermont Castings Authorized Dealer or CFM Corporation if
the purchase was direct with the following information:

1. Name, address, and telephone number of the purchaser.

2. Date of purchase.

3. Serial number from the label on the back.

4. Nature of the defect or damage.

5. Any relevant information or circumstances, e.g., installation,

mode of operation when defect was noted.

A warranty claim will then start in process. CFM Corporation reserves
the right to withhold final approval of a warranty claim pending a visual
inspection of the defect by authorized representatives.
