Installation
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 standards. The test standard
is EN13240:2001 + A2:2004 for Europe. 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 countries. Before
starting the installation, review your plans with the local
building authority. You local dealer can provide any additional information needed.
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.
All local regulations, including those referring to
national and European standards, need to be complied with when installing this stove.
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. Whatever kind you use, the chimney
and chimney connector must be in good condition and
kept clean. Figure 2 shows the two chimney types.
A prefabricated
double-wall insulated chimney
A tile-lined ma
sonry chimney
Fig. 2 Standard 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 flue and chimney design must meet requirement
J2, Part J of the building regulations 2000 (Combustion
Appliances and Fuel Storage Systems).

Intrepid II Woodburning Stove
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 chimney 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
These should be an internal diameter of 150 mm (6”)
and be of the twin wall insulated construction that has
been approved for solid fuel use (e.g. Rite Vent ICS of
ICID Lite Chimney Systems). Diameters over 200 mm
(8”) are not recommended due to the large cross-section causing excessive cooling of the flue gases.
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 200 x 200 mm (8”
x 8”), and into a round flue size of 150 mm (6”).
It may not be vented into larger chimneys without a liner
to reduce the effective flue size to 150 mm (6”) 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.
Connecting Flue Pipes
Connector pipes should meet the requirements of the
building regulations. This can be achieved by the use
connecting fluepipes included in the following categories:
a) Vitreous enamelled steel pipe complying with BS
6999: 1989 (1996);
b) Pipes made from stainless steel as descirbed in BS
EN 1008-1:1995 grades 1.4401, 1.4404, 1.4432 or
1.4436 with flue wall thickness of at least 1 mm;
c) Mild steel fluepipes complying with BS 1449: Part 1:
1991, with a flue wall thickness of at least 3 mm;
d) Cast iron fluepipes complying with BS 41: 1973
(1998).
Flue Pipes with a spigot and socket joint should be
fitted with the socket facing upwards, to contain condensates and moisture within the flue. Joints should be
made gas tight using proprietary jointing accessories,
or, where appropriate, by packing joint with noncombustible rope and fire cement.
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 150 mm (6”) 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 660 mm (26”) from the ceiling.
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 20 mm per
m (1/4” per foot) going from the stove toward the chimney. The recommended maximum length of a horizontal
run is 914 mm (36”). The recommended total length of
chimney connector is 2.4 m (8’).
In cathedral ceiling installations, extend the prefabricated chimney down to within 2.4 m (8’) of the stove.
SAFETY NOTE: ALWAYS WEAR GLOVES AND PROTECTIVE EYEWEAR WHEN DRILLING, CUTTING OR
JOINING SECTIONS OF CHIMNEY CONNECTOR.

Double-wall Chimney Connector
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 on Page 9.
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
3 mm (1/8”) 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 telscoping joints, with at least
three sheet metal screws.
Fig. 3 The crimped end of
the connector points toward
stove.
The pre-drilled holes in
the top of each section of
chimney connector serve as guides when you drill 3 mm
(1/8”) holes in the bottom of the next section.
• Secure the chimney connector to the chimney. In-
structions 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 installations. They often
eliminate the need to cut individual connector sections.
Consult your local dealer about these special pieces.
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 fall
ing from the inner walls of the chimney will stay inside
the chimney connector.
Securing the Single-wall Connector to a
Masonry Chimney
For masonry chimneys, both freestanding and fireplace
chimneys may be used for installation of your Intrepid II.
Freestanding Chimney Installations
If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations in the Wall Pass-through section that follows.
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. 4)

Securing the Single-wall Connector to a
Prefabricated Chimney
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.

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.

Fig. 5 The thimble, made of either ceramic or metal, must be
cemented securely in place.
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 25 - 50 mm (1-2”)
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.
Fireplace Chimney Installations -
Above a Fireplace
The Intrepid II may be connected to a chimney above a
fireplace opening also. In such installations, the stove is
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. 6)
The chimney liner should extend to the point at which
the chimney connector enters the chimney.
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
These Clearances

ST244
• Check the clearance between the chimney con-
nector and the ceiling. If no heat shields are used, the
clearance should be at least 660 mm (26”). 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 635 mm (25”), 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. 7) Fireplace installations,
whether connected to the flue above or through the fireplace opening, have special clearance requirements to
adjacent trim and the mantel. You will find the required
clearances for the Intrepid II fireplace installations on
Page 9.
Floor protection requirements also apply to fireplace
installations. Floor protection information is on Page 8.

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.
The following illustration shows one method of passing a connector througha wall. All combustible material
in the wall is cut away to provide the required 460 mm
(
18”) 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 25 mm (1”) clear of the wall.
Your local dealer or your local building inspector can
provide details for other approved methods of passing
a chimney connector through a combustible wall in your
area.
DO NOT CONNECT AN INTREPID II TO ANY AIR
DISTRIBUTION DUCT OR SYSTEM.

Hearths
This appliance must be installed on to hearth that
meets the requirements of Part J of the Building Regulations 2000 (Combustion Appliances and Fuel Storage
Systems). This can be achieved by ensuring that the
hearth is constructed and sized in accordance with the
guidelines included in section 2 of approved document
‘J’. The size and clearances of the hearth are as follows:
The constructed hearth should be constructed in accordance with the recommendations in document J,
and should be of minimum width 840 mm and minimum
depth 840 mm (if a free standing hearth b) above) or
a minimum projection of 150 mm from the jamb (if a
recessed hearth a) above).

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 9. 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.
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: 406 mm (16”)
from the front. Fireplace hearths must also offer the
required protection of 152 mm (6”) on either side.
Optional 76 mm (3”) 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.
Keep the Stove 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
Appliance
Doors
Perimeter should be
clearly marked e.g.
edge of superimposed
hearth
ST912
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 surfaces. In
addition, furnishings and other combustible materials
must be kept away from the stove as well. In general, a
distance of 1220 mm (48”) 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.
Clearances
As with any solid fuel heating stove, extremely high
surface temperatures can occur, particularly in the
event of uncontrolled operation, e.g. if the doors
are inadvertently left open. It is crucial that sufficient clearances are allowed to any combustible
surfaces, e.g. wooden mantels or lintels, and to
timber framed (studded) walls even if they are faced
with noncombustible board. Detailed information
on fireplace and hearth construction is provided
in section 2 of Document J, all installations must
comply with these requirements or with the relevant
National or local building standards.
Clearances to timber framed (studded) walls are included below. There are no specific minimum clearances
to solid noncombustible surfaces (e.g. the sides and
rear of Inglenook fire openings constructed from solid
masonry) other than to allow safe access to the controls
of the stove. For this reason minimum side clearances
of 125 mm, and a minimum rear clearance of 50 mm
are recommended.

Summary of Clearances
Minimum recommended side clearances to noncombustible surfaces 125 mm (5”).
Minimum recommended rear clearance to noncombustible surfaces 50 mm (2”).
NOTE: The minimum thickness of solid noncombus-
tible materials is specified in section 2 of Document ‘J’,
in relation to the clearance of the appliance from the
surface. As a general rule, the thickness of solid noncombustible material forming the recess of a fireplace is
a minimum of 200 mm.
Minimum rear clearance from combustible walls
(e.g. timber framed or studded walls) 610 mm (24”)
measured from the rear edge of the stove top. (Fig.

Connecting Flue Pipe - Clearances
Single wall connecting fluepipes can reach extremely
high temperatures; therefore, clearances from the connecting fluepipe (chimney connector) must comply with
the requirements of Part J of Building Regulations 2000
(Combustion Appliances and Fuel Storage Systems).
This can be achieved by following the recommendations of Approved Document ‘J’. These are as shown in
Figure 12.
