Introduction
Thank you for choosing a Vermont Castings Intrepid to meet your heating needs. We’re confident you will find the
Intrepid to be an effective wood-burning heater incorporating modern, non-catalytic combustion technology with the
classic aesthetic appeal of its Vermont Castings lineage.
The Intrepid achieves high-efficiency through precisely calibrated delivery of primary and secondary air into a refrac-
tory-insulated firebox. Properly operated and maintained according to the guidelines in this manual, your Intrepid will
provide safe, dependable, and economical heating for years to come.
The Intrepid Model 1640 series has been tested and is listed by the Canadian Standards Associa-
tion (CSA). The test standards are ANSI/UL-1482 for the United States and ULC S627 and CAN/CSA
B366.2 for Canada.
The Intrepid Model 1640 is listed for burning wood fuel only. Do not burn other fuels.
The Intrepid Model 1640 is approved for installation in manufactured (mobile) homes in the United
States only using the optional Mobile Home Kit #1881 in accordance with the instructions in that kit
and any local codes.
The Intrepid Model 1640 complies with the standards set forth by the Federal Environmental Protection Agency, 40
CFR Part 60.532(b)(2), as stated on the permanent label attached to each stove.
We recommend that you hire a professional, solid-fuel stove technician to install your Intrepid, or to advise you on the
installation should you attempt to install it yourself. Consult the authority having local jurisdiction (such as a municipal
building department, fire department, fire prevention bureau, etc.) before installation to determine the need for a build-
ing permit. Also, consult your insurance agent to be sure your installation complies with specific requirements that may
vary locally.
In addition to directions on installation and operation, this manual includes directions on maintenance and assembly.

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 efficien-
cies.
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 construc-
tion (e.g., unusually well insulated, not insulated, built under
ground, 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 PROP-
ERLY INSTALLED, OPERATED AND MAINTAINED, A
HOUSE FIRE MAY RESULT. FOR SAFETY, FOLLOW
ALL INSTALLATION, OPERATION AND MAINTE-
NANCE DIRECTIONS. CONTACT LOCAL BUILDING
OFFICIALS ABOUT RESTRICTIONS AND IN�.
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 clear-
ance requirements.
• The floor protector is large enough and is construct-
ed properly to meet all requirements.
• You have all necessary permits from local authori-
ties.
Your local building official is the final authority for ap-
proving 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. Clear-
ance 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, Fire-
places, Vents and Solid Fuel Burning Appliances. In
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.

Reference Point AC617
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 connec-
tor 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, build-
ing 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 con-
firm 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 wallpa-
per 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. Ma-
sonry chimneys must be lined, either with code-ap-
proved masonry or precast refractory tiles, stainless
steel pipe, or a code-approved, “poured-in-place”
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 test-
ed 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 chim-
ney 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. How-
ever, 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 insu-
lated or have the flue relined for proper stove perfor-
mance.
Ask your dealer about components available for con-
necting 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 chim-
ney 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 con-
nectors 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 recommen-
dations 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 con-
nectors 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 prefabricat-
ed chimney downward to within 8’ (2.4m) of the stove.
SAFETY NOTE: ALWAYS WEAR GLOVES AND PRO-
TECTIVE EYEWEAR WHEN DRILLING, CUTTING OR
JOINING CHIMNEY CONNECTOR SECTIONS .

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 connec-
tors, 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 bot-
tom 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 mate-
rial.
Note: Special slip pipes and thimble sleeves that form
telescoping joints between sections of chimney con-
nector 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 chim-
ney and the chimney connector. The top of such adap-
tors 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 combus-
tible wall to reach the chimney, follow the recommenda-
tions 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 con-
nector 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 chim-
ney connector to the outer end of the sleeve with sheet
metal screws.

Connection Above the Fireplace
In this installation, the chimney connector enters the
fireplace flue though a thimble located above the fire-
place. 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 install-
ing 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 neces-
sary, use a combination of mantel, trim, and connec-
tor 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 instal-
lation, check with your building inspector before you
begin. Also check with the chimney connector manu-
facturer 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 com-
bustible 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 pass-
though 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 dealer or
your local building inspector can provide details of other
approved methods of passing a chimney connector
through a combustible wall.
In Canada, this type of installation must conform to
CAN/CSA-B365, Installation Code for Solid Fuel Burn-
ing Appliances and Equipment.
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 Vermont Castings Bot-
tom 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.
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 with-
out 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.
fire-parts.com

9
Intrepid 1640 Woodburning Stove
30000830
In Canada, the floor protector required under the stove
must extend 18” (457mm) to the front (‘E’, Fig. 14), and
8” (203mm) from the sides and rear. (‘D’ ,Fig. 14)
To meet Canadian requirements, a floor protector must
be at least 43” (1092mm) wide and 48” (1219mm)
deep.
Floor protection also must extend under the chimney
connector and 2 inches to either side. (‘C’, Fig. 14)
For 6” (152mm) connector used with the Intrepid II, the
protector must be a minimum of 10” (254mm) wide,
centered under the connector.
Fig. 14 These dimensions are minimum requirements only.
Use greater dimensions whenever possible.

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 com-
bustible 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” (416 mm)
from the front in the United States and 18” (457 mm)
from the front in Canada.
The optional 3” (75 mm) legs may be used only on
hearths that meet the width and depth requirements.
Hearth rugs do not satisfy the requirements for floor
protection as they are only fire-retardant, not fire proof.
Mobile Home Installation
The Intrepid is approved for use in manufactured
(mobile) homes when installed with the optional Ver-
mont 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’ (914 mm) above the part
of the roof through which it passes. The top of the
chimney must extend at least 2’ (610 mm) above the
highest point of any part of the mobile home struc-
ture within 10’ (3 m) of the chimney.

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 connec-
tor itself, to the adjacent combustible surface. Do not
measure from the heat shields of the stove or connector
to the combustible surface.

6. If the chimney exits the mobile home through a wall
at a point 7’ (2.1 m) 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 trans-
portation 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 main-
tained.
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 over-
heat.
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 stove has no listed heat shield in-
stalled.
• When the stove does have a listed heat shield
mounted on it.
• When the wall has no listed heat shield installed.
• When the wall does have a listed heat shield
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.
Wall Shields
Wall shields should be constructed of 24 gauge or
heavier sheet metal, or another noncombustible mate-
rial 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 sur-
face 1" (25mm) on noncombustible spacers. The spac-
ers 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.
The following examples of wall shield construction illus-
trate common designs used to safely achieve reduced
clearances to combustible wall materials.

Fireplace Clearances and
Mantel Trim Shields
A fireplace installation requires special clearance be-
tween 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.
Noncombustible shields installed 1” (25mm) away from
the combustible surface on noncombustible spacers,
called ventilated shields, may be used to reduce clear-
ances.
To protect a mantel from the heat of an Intrepid II in a
fireplace installation, the ventilated mantel shield must
be at least 48” (1219mm) 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. 20. ) cannot be more
than 9” (229mm) deep and must have a minimum clear-
ance of 30” (762mm), measured from the stove’s top
plate. With a ventilated shield, this clearance may be
reduced safely to 14” (357mm).
Unprotected top trim (B) protruding 2” (51mm) or less
from the face of the fireplace must be a minimum of 24”
(610 mm) from the stove’s top surface. With a venti-
lated trim shield, this clearance may be reduced safely
to 14” (357mm).
Unprotected side trim (C) that protrudes 2” (51mm) or
less from the face of a fireplace must have a minimum
clearance of 15” (381mm), measured from the stove’s
top side edge. With a ventilated trim shield, the clear-
ance may be reduced safely to 10” (254mm). If the trim
extends more than 2” (51mm), wall clearance require-
ments apply.

Attach the Chimney Connector
1. Insert the crimped end of the first section of chimney
connector into the flue collar.
2. Using the holes in the collar as guides, drill 1/8”
(3mm) holes through the connector pipe.
3. Use the three #10 x 1/2” sheet metal screws pro-
vided to secure the chimney connection to the flue
collar.
If applicable, attach Chimney Connector Heat Shields
following the instructions included with those parts.
Flue Collar Reversal
The Intrepid is shipped with the Flue Collar in the Top
Exit position. Follow these steps to orient th collar for a
Rear Exit installation.
1. Remove the Flue Collar Heat Shield, (used for top-
exit installations only).
2. Remove the two screws that attach the flue collar to
the stove and turn the collar upside-down to face the
rear.
3. Confirm that the gasket is seated properly and rese-
cure the screws.
Install the Outside Air Adaptor
The optional #1878 Outside Air Adaptor provides a col-
lar to which a 3 inch diameter air duct may be attached
directly to the air inlet area at the back of the stove.
Use the four sheet metal screws provided in the kit to
attach the adaptor to the center mounting flange at the
bottom of the Rear Shroud.
Install Smokeshelf / Firebricks
Look inside the firebox and locate the position for the
Smokeshelf. It will seat against the upper Back, directly
under the Flue Collar. It is supported by ribs cast into
the air manifolds on either side and along the back
plate. (Fig. 29)
1. Orient the Smokeshelf Plate as illustrated and apply
a bead of furnace cement along the rib at the back
edge.
2. Apply a bead of cement along the top of each Side
Rib on which the Smokeshelf will rest. (Fig. 29)
3. Position the Smokeshelf above the #3 Air Tube so
that it seats against the Back wall and upon the Side
Ribs.
4. Insert the three Upper Firebricks into position above
the Secondary Air Tubes as shown in Figure 30. In-
sert the bricks up betweeen the #1 and #2 Air Tubes.
The firebricks do not need cement - they simply rest
directly upon the air tubes. Push each firebrick fully
back against the Smokeshelf plate.

Intrepid 1640 Woodburning Stove
30000830
Operation
You will 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 no longer than 16” (410 mm) in length,
however, you will find that shorter wood lengths ease
refueling and promote the most efficient combustion.
The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and air-
dried outside under cover for at least one year.
For areas that do not have a supply of hardwood, com-
monly burned softwoods include tamarack, yellow pine,
white pine, Eastern red cedar, fir, and redwood. These
too should be properly dried.
Keep wood a safe distance from the heater and keep
it out of the areas around the heater used for refueling
and ash removal.
Use the Air Control Setting that Works
Best for You
No single air control setting will be appropriate for
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, and could even damage it. On the other
hand, too little draft can cause backpuffing into the
room and/or the “plugging” of the chimney.
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncon-
trollable burn or a glowing-red stove part. A sign of in-
adequate draft is smoke leaking into the room through
the stove or chimney connector joints, low heat, and
dirty glass.
In newer homes that are well-insulated and weather-
tight, poor draft may result from insufficient air in the
house. In such cases, a slightly opened window near
the stove on the windward side of the house will pro-
vide the fresh air needed.
Do not use chemicals or fluids to start the fire.
Do not burn garbage or flammable fluids such
as gasoline, naptha, or engine oil. Also, never
use gasoline-type lantern fuel, kerosene, char-
coal lighter fluid, or similar liquids to start or
“freshen up” a fire. Keep all such liquids well
away from the Intrepid while it is in use.
Caution: The Intrepid will be hot while in op-
eration. 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. If any part of the stove
glows, you are overfiring.
How the Intrepid Works
Combustion control is achieved in the Intrepid through
two separate air delivery systems.
The Primary Air Control Lever, located at the left rear
corner of the stove, controls the amount of incoming pri-
mary air for starting, maintaining, and reviving the 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), place the lever all the way
to the LEFT at the HIGH position. For a fire that will
last longer with less heat, move the lever to the RIGHT
toward the LOW position. You can set the lever any-
where in between the upper and lower extremes to
moderate the fire intensity. (Fig. 27)
Another separate supply of oxygen is delivered to the
upper area of the firebox to support combustion of
gases released from the main fuel bed. This Second-
ary Air enters the stove through two, unrestricted inlets
and is heated while passing through separate channels
before being delivered through three stainless steel
multi-ported tubes located at the top of the firebox.
Burn Only High-Quality Wood
The Intrepid is designed to burn natural wood only;
do not burn any other fuels.
fire-parts.com

19
Intrepid 1640 Woodburning Stove
30000830
A more effective option for delivering ample 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. The
optional Intrepid Outside Air Adaptor is available from
your dealer.
When you first begin using the stove, pay attention
to the effects of different 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.
Do not for any reason attempt to increase the firing
of your heater by altering the air control adjustment
range outlined in these directions.
Before you start using the stove, please read the Ap-
pendix on Draft Management starting on Page 24 to
learn how the characteristics 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.
Starting and Maintaining a Fire
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 tempera-
ture. When you first begin using your Intrepid, minimize
thermal stress by allowing the plates to adjust gradually
during three or four initial break-in fires following Steps
1- 3.
Burn solid wood fuel only, and burn it directly on
the grate. Do not elevate the fuel. Do not burn coal
or other fuels.
WARNING: operate this stove only with the door
fully closed.
The Primary Air Inlet must be open when starting a
fire or when refueling.
1. Open the primary air control fully by placing the Con-
trol Lever all the way to the LEFT (HIGH).
2. Place several sheets of crumpled newspaper in the
stove. Avoid using glossy or colored paper, as these
burn poorly. At the front of the firebox, 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-
50 mm) in diameter. (Fig. 28)
3. Light the newspaper and close the door. Gradually
build up the fire by adding a few 3-5” (80-120 mm)
diameter splits. (Fig. 29) 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 op-
tional stove-top 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
sustain a fire. Roll up a couple pieces of newspa-
per, place them on top of the kindling and toward
the front of the stove, light them, and close the door.
This should heat the chimney enough to initiate
strong draft.
Once the draft is established, open the front door
and light the rest of the fuel bed at the bottom. Do
not light the main bed of fuel until the chimney be-
gins drawing.
4. Afer the stove has been broken-in using Steps 1-3,
continue to build the fire gradually. Add larger wood
with a diameter of 3-4” (76-102mm).
Continue adding split logs of this size to the briskly-
burning fire until there is a glowing ember bed at
least 2” (51mm) deep. A good ember bed is neces-
sary for proper functioning and may take up to an
hour to establish.
5. Adjust the Air Control Lever to maintain the desired
heat output.
Refuel While the Embers Are Still Hot
WARNING: For safety and greatest efficiency, oper-
ate your stove only with all doors fully closed. The
test standard for your stove when it is operated in this
mode is UL 1482 for the United States and ULC S627
for Canada.
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 for the United States and CAN/
CSA-B366.2 for Canada.
Use only the Intrepid Spark Screen, #0136 with your
Intrepid. Intrepid Spark Screens are available from your
Vermont Castings’ Authorized Dealer.
Reload the Intrepid 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 return to its operating temperature
quickly. Wear stove gloves, and follow this procedure
when you reload your stove:

1. Place the Air Control Lever to the fully open (HIGH)
position
2. Open the door and check the ash level in the ash
pan. If necessary, dispose of the ashes and replace
the pan.
3. Use a fireplace tool to break up the charcoal and
direct ash through the grate. Pull the charcoal from
the back to the front. (Fig. 30) This will encourage
efficient combustion as the fuel burns from front to
rear.
4. Load wood — smaller, split pieces first. Close the
door. Ideal performance will be achieved by oper-
ating with the air control set at HIGH for several
minutes after refueling. Adjust the Air Control Lever
for the desired heat output after the fire is re-estab-
lished.
Fig. 33 Gradually add larger pieces of wood until all the wood
is burning well.
