Installation
SAFETY NOTICE: IF YOUR STOVE IS NOT PROPERLY INSTALLED, OPERATED AND MAINTAINED,
A HOUSE FIRE MAY RESULT. FOR SAFETY,
FOLLOW ALL INSTALLATION, OPERATION AND
MAINTENANCE DIRECTIONS. CONTACT LOCAL
BUILDING OFFICIALS ABOUT RESTRICTIONS AND
INµ.
Before you begin an installation, review your plans to
be certain 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 authori-
ties.
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
the stove indicates that the Intrepid has been tested to
current UL and ULC standards by CSA. Clearance and
installation information is also printed on the label.
Local authorities generally will accept the label as
evidence that, when the stove is installed according to
the information on the label and in this manual, the
installation meets codes and can be approved. Codes,
however, vary in different areas. Before starting the
installation, review your plans with the local building
authority. Your local dealer can provide any additional
information needed.
For any unresolved questions about installation, refer to
the National Fire Protection Association’s publication
ANSI/NFPA 211–1988 Standard for Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances
Canada, the equivalent publication is
CSA CAN-B365,
Installation Code for Solid Fuel Burning Appliances and
Equipment.
These standards are the bases 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.

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.
. In
Chimneys
Your stove must be connected either to a sound
masonry chimney that meets local codes, to a relined
masonry chimney that meets local codes, or to an
approved prefabricated metal chimney. Whichever of
those types you use, the chimney and chimney connector must be in good condition and kept clean.
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 make the inspection or direct you to someone who
can.
The chimney should 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).
To assure proper draft and good performance, any
chimney used with this stove should extend at least 16'
(5 m) above the flue collar of the stove.

Masonry Chimneys
An existing masonry chimney must be inspected to
confirm that it has a lining. Do not use an unlined
chimney. The chimney also should be examined for
cracks, loose mortar, other signs of deterioration, and
blockage. Repair any defects before the chimney is
used with your stove.

Masonry Chimneys, cont'd.
• Unused openings in an existing masonry chimney
must be sealed with masonry to the thickness of the
chimney wall, and the chimney liner should be
repaired. Openings sealed with pie plates or wallpaper are a hazard and should be sealed 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 local building code, or, in the absence
of a local code, to a recognized national code.
Masonry chimneys must be lined, either with codeapproved masonry or precast refractory tiles, stainless steel pipe, or a code-approved, "poured-inplace" liner. The chimney clean-out door must seal
tightly to ensure a good draft.
Prefabricated Chimneys
A prefabricated metal chimney must be one that is
tested and listed for use with solid-fuel burning appliances to the High-Temperature (H.T.) Chimney Standard UL-103-1985 (2100°F.) for the United States, and
High Temperature (650°C) Standard ULC S-629 for
Canada.
Chimney Size
This stove is approved for venting into a masonry chimney with a nominal flue size of 8" x 8" (203 x 203mm),
and into a round flue size of 8" (203mm) or 6" (152mm).
It may be vented into larger chimneys as well. However, chimneys with liners larger than 8" x 12" (203 x
305mm) may experience rapid cooling of smoke and
reduction in draft, especially if they are located outside
the home. Such large chimneys may need to be
insulated or have the flue relined for proper stove
performance.
Do not connect this unit to a chimney flue
serving another appliance.
Note: Do not vent this stove into a factory-built
(zero-clearance) fireplace. This stove has not
been tested and listed for that type of installation. Factory-built fireplaces 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 the STOVE to any air distribution duct or system.
Ask your dealer about components available for connecting the stove to a steel chimney liner.
Chimney Connector Guidelines
A chimney connector is the double-wall or single-wall
pipe that connects the stove to the chimney. The
chimney itself 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. They are for interior use only.
Double-wall connectors must be tested and listed for
use with solid-fuel burning appliances. Single-wall
connectors should be made of 24 gauge or heavier
steel, and should be 6" (152mm) in diameter. Do not
use galvanized chimney connector; it cannot withstand
the high temperatures that can be reached by smoke
and exhaust 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 recommendations
in the section following
on Wall Pass-throughs.
Do not pass the
connector through an
attic, a closet or any
similar concealed
space. The whole
chimney connector should be exposed and accessible
for inspection and cleaning.
Install the single wall chimney connector not less than
18" (457mm) from the ceiling. Keep it as short and
direct as possible, with no more than two 90° turns. If
possible, use 45° elbows. Slope horizontal runs of
connectors upward 1/4" per foot (20 mm per meter)
going from the stove toward the chimney. The recommended maximum length of a horizontal run is 3 feet (1
meter), and the total length of chimney connector
should be no longer than 8’ (2.4meters).
In cathedral ceiling installations, extend the prefabricated chimney downward to within 8’ (2.4m) of the
stove.
SAFETY NOTE: ALWAYS WEAR GLOVES AND
PROTECTIVE EYEWEAR WHEN DRILLING,

Double-wall Chimney Connectors
The Intrepid is approved for installation in the U.S. and
Canada with double-wall chimney connectors that have
been tested and listed for use with solid-fuel burning
appliances by a recognized testing laboratory.
Follow the instructions for assembling and installing
double-wall connectors provided by the manufacturer of
the double-wall chimney. To ease assembly and help
assure safety, use chimney components manufactured
by a single source.
NOTE: For installations using double-wall
connectors, minimum clearances must conform to
those listed in the clearance chart on Page 14.

Single-wall Chimney Connectors
• 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 between sections of chimney
connector, including telescoping joints, with at least
three sheet metal screws. The predrilled 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.
Instructions for various installations follow.
• 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 assembly. Slip pipes
eliminate the need to cut individual connector sections.
Consult your local dealer about these special connector
sections.
Securing the Single-wall Connector to a
Prefabricated Chimney
Follow the installation instructions of the chimney
manufacturer exactly.
Special adaptors are available from your local dealer to
make the connection between the prefabricated chimney and the chimney connector. The top of such
adaptors attach directly to the chimney or to the
chimney’s ceiling support package. The bottom of the
adaptor is secured to the chimney connector.
The adapter forms a union between the chimney and
chimney connector that ensures any soot or creosote
falling from the inner walls of the chimney will stay
inside the chimney connector.
Securing the Single-wall Connector to a
Masonry Chimney
The Intrepid may be connected to either a freestanding
masonry chimney or to a fireplace masonry chimney.
Freestanding Installations
If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations for Wall Pass-Through construction on Pages
7-8.
The opening through the chimney wall to the flue - the
"breech" – must be lined with a ceramic or metal
thimble which is securely cemented in place.
A metal pipe section called the “thimble sleeve,” slightly
smaller in diameter than standard connector and the
thimbles, will allow the removal of the chimney connector system for inspection and cleaning. Thimble
sleeves are available from your local dealer.
To install a thimble sleeve, slide it into the breech until it
is flush with the inner flue wall. Be sure that it does not
extend into the flue passage where it 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.

INTREPID II
Connection Above the Fireplace
In this installation, the chimney connector enters the
fireplace flue though a thimble located above the
fireplace. The liner of the fireplace chimney should
extend at least to the point at which the chimney
connector enters the chimney. Follow all the guidelines
for installing a chimney connector into a freestanding
masonry chimney, and pay special attention to these
additional points:
• Check the stove and chimney connector clearances
to combustible mantel and trim materials. If necessary, use a combination of mantel, trim, and connector heat shields to provide the required clearances.
Refer to Page 12.
• Double-check connector clearance to the ceiling.
• The fireplace damper must be closed and sealed to
prevent room air from being drawn up the flue which
could reduce performance. However, it must be
possible to reopen the damper to inspect or clean
the chimney.
• Floor protection requirements also apply to fireplace
installations. Refer to Page 8.
Wall Pass-throughs
Whenever possible, design the installation so that the
connector does not pass through a combustible wall. If
you must include 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.
Consult with your dealer regarding special connection
components available for use as wall pass-throughs.
Use only parts that have been tested and listed for use
as a wall pass-through. Refer to Figures 9 - 12 for
further details.
U.S. Requirements:
The National Fire Protection Association (NFPA) has
established guidelines for use in the United States for
passing chimney connectors through combustible walls.
Many building code inspectors follow these guidelines.
Figure 9 shows one NFPA-approved method. All
combustible material in the wall is cut away to provide
12" (305mm) clearance to the connector. Brick and
mortar are used to enclose the clearance area.

Canadian Requirements:
In Canada, the Canadian Standards Association has
established specific guidelines regarding wall passthough design. Figure 13 shows one approved method
in which all combustible material in the wall is cut away
to provide the required 18" (457mm) clearance around
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" (25mm) clear of the wall. Your local

protector, 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.
When the optional 3” (75mm) short legs are used, the
bottom heat shield must be used.
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 - ( ‘E’ in Fig. 14), and
at least 6” from the sides and rear (‘D’, Fig. 14).
To meet the requirement in the United States, a floor
protector must be at least 34” wide and 40” deep.

Fireplace Hearth Protection
Do not assume that 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. Because heat is
readily conducted by brick or concrete, 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.
For all fireplace installations, follow the floor protection
guidelines described above.
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: 16" (416mm)
30000830
Mobile Home Installation
The Intrepid is approved for use in manufactured
(mobile) homes when installed with the optional
Vermont Castings Mobile Home Kit #1881 in
accordance with the instructions provided with that kit
and any local codes. This approval applies only in the
United States.
In addition to the standard installation requirements
described in this manual, the following guidelines apply
to mobile home installations:
1. The stove must be permanently secured to the floor
using the leg clamps and fasteners provided in the
kit.
2. The stove must have a permanent connection to the
outside to supply combustion air.
3. The stove must be grounded to the steel chassis of
the mobile home.
4. A listed chimney system, including roof thimble,
spark arrestor, chimney supports, roof flashing and
any other components suitable for use in mobile
homes must be used. The chimney system must
comply with the standard for Chimneys Factory-Built
Residential Type and Building Heating Appliances
UL 103.
5. The chimney must be attached directly to the stove
and must extend at least 3’ (914mm) above the part
of the roof through which it passes. The top of the
chimney must extend at least 2’ (610mm) above the
highest point of any part of the mobile home structure within 10’ (3m) of the chimney.
9
Intrepid 1640 Woodburning Stove
6. If the chimney exits the mobile home through a wall
at a point 7’ (2.1m) or less above the ground level on
which the mobile home is located, a guard or other
noncombustible enclosure must be fitted at the point
of exit and extend up to a height of 7’ (2.1m). Any
openings in this guard must be smaller than 3/4”
(19mm).
7. Check all local building codes, specifically those
related to mobile homes. Other requirements may
be applicable to chimney system removal for transportation of the mobile home.
WARNING: Do not install the Intrepid in a sleeping
room or hallway.
CAUTION: The structural integrity of the mobile
home roof, floor, walls and ceiling must be maintained.
Clearance to Surrounding
Combustible Materials
When the stove is operating, both the stoveplate and
the chimney connector radiate heat in all directions. A
safe installation requires that adequate clearance be
maintained between the stove and nearby combustible
materials to ensure that those materials do not
overheat.
Clearance is the distance between either your stove or
chimney connector, and nearby walls, floors, the
ceiling, and any other fixed combustible surface. Keep
furnishings and other combustible materials away
from the stove as well. In general, a distance of 48"
(1219mm) must be maintained between the stove and
moveable combustible items such as drying clothes,
furniture, newspapers, firewood, etc. Keep this area
empty of any combustible material.
Safe Ways To Reduce Clearances
The Intrepid clearance requirements, listed and
diagramed on Pages 14-15, have been established
through testing to UL and ULC standards to meet most
installation configurations. These involve four basic
variables:
• When the
stalled.
• When the
mounted on it.
• When the
• When the
mounted on it.
In general, the greatest clearance is required when the
stove will be positioned with no heat shield near a wall
with no heat shield. The least clearance is required
when both the stove and the wall have heat shields.

Reducing a stove clearance may require installation of
a listed heat shield on the chimney connector as well.
Clearances may be reduced only by means approved
by the regulatory authority, or in accordance with the
clearances listed in this manual.
When determining clearance, always measure from the
top plate of the stove, or, from the chimney connector
itself, to the adjacent combustible surface. Do not
measure from the heat shields of the stove or connector to the combustible surface.
Wall Shields
Wall shields should be constructed of 24 gauge or
heavier sheet metal, or another noncombustible material such as 1/2" (13mm) insulation board or common
brick "laid on flat," with the 3¹⁄₂" (89mm) side down.
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. (Fig. 16)
Air must be able to flow between the wall and the
shield. At least 50% of the bottom 1" (25mm) of the
shield should be open and the shield must be open at
the top.
