When planning the installation, consider the location of the
vent terminal and clearances. Some of the most common
clearances to keep in mind are shown in Figure 11.

Important: All vent clearances must be maintained.
Check your vent termination clearances against Fig­ures 11 and 12.

The vent should be placed so that people cannot be burned
by accidentally touching the vent surfaces when the stove
is operating.

The vent termination should be located where it cannot be
damaged by such things as automobile doors, lawn mowers
or snowblowers and it should be located away from areas
where it could become blocked by snow, etc.

Some considerations are:

• Obstructions or impediments to venting.

• Nearby combustible materials that could come into

contact with combustion exhaust gases.

• Other nearby openings {within 9” (230 mm)} through

which exhaust gas could reenter the building.

• All vegetation within 3’ (914 mm) that may interfere with

the draft.

Other factors that inuence where the installation will be

sited include the location of outside walls, where additional
heat may be desired in the home, where the family mem­bers gather most regularly, and perhaps most importantly,
the distance limitations of the venting system.

Your stove is approved to be vented either through the side
wall, or vertical through the roof.

• Vermont Castings Group does not require any open-

ing for inspection of vent pipe.

• Only venting components specically approved and

labelled for this stove may be used.

• Minimum clearances between vent pipes and com-

bustible materials is one (1”) inch (25mm), except
where stated otherwise.

• Venting terminals shall not be recessed into a wall or

siding.

• Horizontal venting must be installed on a level plane

without an inclining or declining slope.

There must not be any obstruction such as bushes, garden
sheds, fences, decks or utility buildings within 24” from the
front of the termination hood.

Do not locate termination hood where excessive snow or ice
build up may occur. Be sure to check vent termination area
after snow falls, and clear to prevent accidental blockage
of venting system. When using snow blowers, make sure
snow is not directed towards vent termination area.

Location of Vent Termination

It is imperative the vent termination be located observing
the minimum clearances as shown in Figure 11.

IMPORTANT

• The horizontal termination must not be recessed

into the exterior wall or siding.

• Horizontal vent runs must be level toward the vent

termination.

• Clearances around the vent termination must be

maintained.

Intrepid® Direct Vent - Rear Vent Gas Heater

Venting System Assembly

General Information

The Intrepid is approved for installation only with the Dura
Vent components listed on page 14. Follow these and the
vent component instructions exactly.

For U.S. installations: The venting system must conform
with local codes and/or the current National Fuel Gas Code,
ANSI Z223.1/NFPA 54

For Canadian installations: The venting system must
conform to the current CSA B149.1 installation code.

Options

The DuraVent Direct Vent Pro offers a complete line of
component parts for both horizontal and vertical installa­tion. Many items are offered in decorative black as well

as galvanized nish. The galvanized pipe and ttings may

be used for concealed locations such as attics, or spaces

where corrosion is a factor, such as above the rooine.

Decorative black painted sections are recommended for
use on visible interior runs. Decorative brass trim kits are
available for both Wall Thimbles and Ceiling Support Box­es. Snorkel Terminations are available for applications
which may require vertical rise on the building exterior.

Planning Your Installation

There are two basic types of Direct Vent Pro installa­tions:

Horizontal Termination (Figs. 18 and 19)
Vertical Terminations (Fig. 20)

When planning your installation, it will be necessary to
select the proper length of vent pipe for your particular
requirement. For horizontal installations, check these in­structions to determine the minimum clearance from the
rear of the appliance to the wall. It is also important to note
the wall thickness. Select the amount of vertical rise de­sired or required, for “vertical-to-horizontal” installations
(verify that it is within the minimum and maximum limits.
Refer to page 8). To determine the length of vent pipe re­quired for vertical installations, measure the distance from
the appliance ue outlet to the ceiling, the ceiling thick­ness, the vertical rise in an attic or second story, and allow

for sufcient vent height above the rooine. For multi-sto­ry applications, restops are required at each oor/ceiling

level. If an offset is needed in the attic, additional pipe and
elbows will be required.

Use components listed on page 14 under ‘Basic Straight
through-the-Wall Installation’ for an installation where the
heater is parallel to the wall and the vent system extends
straight back through that wall.

1. Locate the vent opening on the wall. Refer to Figures
20 & 21 to determine the top of the opening centerline.

It may be necessary to rst position the stove and mea­sure to nd the hole location. Depending on whether the

wall is made of combustible materials, cut the opening to
the size shown in Figure 21. Combustible wall openings
must be framed as shown in Figure 21.

2. Measure the wall thickness and cut the zero clearance

sleeve sections to proper length (MAXIMUM 12”).
Assemble the sleeve with the #8 sheet metal screws

supplied. Attach the restop plate to the sleeve end with

the holes. (Fig. 22) NOTE: The zero clearance sleeve
is required in combustible walls only.

4. Slip the wall cover over the interior end of the horizontal
pipe and install into the zero clearance sleeve. Seal the
joint inside the wall plate if needed to keep cold air from
being drawn into the home.

5. Install the vent terminal. (Fig. 22) Guide the inner and
outer vent termination collars into the adjacent pipes.
Double check that the vent pipes overlap the collars by
2”. Fasten the termination to the outside wall with the
screws provided, and caulk the joint with weatherproof
sealant.

6. Use wall straps to support vertical pipe runs at 4’ (1219
mm) intervals.

Horizontal Installation

Step 1. Set the gas appliance in its desired location.

Check to determine if wall studs or roof rafters are in the
way once the venting system is attached. If this is the
case, you may want to adjust the location of the appli­ance.

Step 2. DirectVent Pro pipe and ttings are designed with

special twist-lock connections. To connect the venting

system to the appliance ue outlet, a twist-lock appliance

adaptor is built into the appliance at the factory. Assemble
the desired combinations of black pipe sections and el­bows to the appliance adapter with pipe seams oriented

towards the wall or oor, as much out of view as possible.

(Fig. 24)

Figure 24

Intrepid® Direct Vent - Rear Vent Gas Heater

Figure 25

ST977

2. Horizontal vent runs of vent pipe must be supported
to prevent any downward sags. Horizontal pipe sec­tions should be supported at least every 4’ (1.2 m).
Wall straps can be used for this purpose. Alternatively,
plumbers tape or other suitable noncombustible mate­rial can be used to support the vent pipe.

3. DirectVent Pro venting requires no sealant.

Step 3. With the appliance adapter and pipe section at­tached, slide the stove into its correct location. Mark the
wall for a square hole that measures 10” x 10” (254 x
254 mm). The centerline of the pipe should line up with
the center of the square hole. (Fig. 26) Cut and frame
the square hole in the exterior wall where the vent will be
terminated. If the wall being penetrated is constructed of
noncombustible material only, i.e. masonry block, brick or
concrete only, a hole with zero clearance is acceptable.

NOTES:

ST976

NOTES:

1. Twist-lock procedure: Line up locking lugs on male
and female ends of pipe sections. Insert the male end
of pipe into the female end until the locking lugs are
covered. Twist the female end clockwise an eighth of a
turn to lock sections together. (Fig. 25) Screws are not
required to secure the joint, but are acceptable pro­vided they do not penetrate the inner wall of the vent
pipe.

1. The horizontal run of venting must be level, or have a
1/4” (6 mm) rise for every 1’ (305 mm) of run toward
the termination. Never allow the vent to run downward.
A downward slope can trap heat and become a pos-

sible re hazard.

20306761

Intrepid® Direct Vent - Rear Vent Gas Heater

2. The location of the horizontal vent termination on an
exterior wall must meet all local and national building
codes, and must not be easily blocked or obstructed.
Refer to Pages 10 and 11 for proper Termination Clear­ances.

For installations requiring a vertical rise on the exterior
of the building, 14” (356 mm) and 36” (914 mm) tall snor­kel terminations are available. (Fig. 27) Follow the same
installation procedures as used for standard horizontal
terminations. If the snorkel termination must be installed
below grade level, (i.e. basement application), proper
drainage must be provided to prevent water from enter­ing the snorkel termination. (Fig. 28) Do not attempt to
enclose the snorkel within the wall or any other type of
enclosure.

Step 4. Position the horizontal termination cap in the cen­ter of the square framed hole, and attach to the exterior
wall with the four (4) wood screws provided. Before at­taching the vent termination cap to the exterior wall, run
a bead of non-hardening silicone sealant around the
outside edges to make a seal between the cap and the
wall. The arrow on the vent cap should be pointing up.
Ensure proper clearances to combustible materials are
maintained. (Fig. 29)

IMPORTANT: You must attach the four (4) pieces of the
new vinyl siding standoff to the horizontal termination cap
in specic order to ensure a weather tight t. Loosely as­semble the four parts, in order, around the base of the hor-

izontal termination cap. Place the rst of four pieces along

the upper edge of the cap, then using two (2) screws per
side, secure each piece to the pre-drilled holes along both
sides of the cap, nally, attach the nal piece to the bot­tom edge of the cap. Tighten all screws and mount cap,
with all four (4) pieces attached, directly onto the wall with
the four (4) 21⁄2" (64 mm) screws provided. (Fig. 30)

3. When penetrating through stucco wall, install the

counter ashing. The counter ashing allows stucco,
or other materials, to be nished directly to the sides
of the termination cap. First attach the counter ash-

ing to the base of the horizontal termination cap with
the small screws provided, then mount entire assem­bly onto the wall with the four (4) 2

1

⁄2" (64 mm) wood

screws provided.

4. If the optional copper version of the horizontal termina­tion cap is installed, use an appropriate noncombusti­ble material to avoid direct contact between the galva­nized and copper metals to prevent possible galvanic
reaction.

Step 5. Before connecting your horizontal pipe sections
to the horizontal termination cap, slide the wall thimble
cover over the pipe section nearest the interior side of
wall. (Fig. 31)

Step 6. Slide the appliance and vent assembly towards
the wall, carefully inserting the pipe section into the cap
assembly. It is important the pipe section extends into the
back of the termination cap with a minimum overlap of
11⁄4" (32 mm). Use the two (2) sheet metal screws pro-
vided to secure the pipe section to the back of the termi­nation cap. The wall thimble cover will cover the screw
heads. (Fig. 31)

Step 1. Check these installation instructions for required

clearances (air spaces) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters or
other nearby combustible surfaces. Do not pack air spac­es with insulation. Check these instructions for maximum
vertical rise of the venting system and any maximum hori­zontal offset limitations.

in the desire location. Drop a
plumb bob down from the ceil­ing to the position of the ap-

pliance ue exit, and mark the

location where the vent will
penetrate the ceiling. Drill a
small hole at this point. Next,
drop a plumb bob from the roof
to the hole previously drilled in

may wish to relocate the appli­ance or to offset, to avoid cut­ting load-bearing members.

Step 3. To install the round ceil­ing support/wall thimble cover

in a at ceiling, cut a 10” x 10”

(254 x 254 mm) square hole in
the ceiling (unless otherwise

specied) centered on the hole

drilled in Step 2. Frame the hole
as shown in Figure 34.

Step 4. If the twist-lock appliance adapter has not been
installed on the stove, do so now.

Step 5. Assemble the desired pipe sections and elbows
necessary to reach from the appliance adapter up through
the round ceiling cover or support box. Ensure that all
pipe and elbow connections are in their fully twist-locked
position.

Step 6. Cut a hole in the roof centered on the small drill
hole placed in the roof in Step 2. The opening should be

of sufcient size to meet the minimum requirements for
clearance to combustibles, as specied. Continue to as-

straps or plumber tape
may be used for this pur­pose. (Fig. 36)

3. Wherever possible, use 45° elbows instead of 90° el-

bows. The 45° elbow offers less restriction to the ow
of ue gases and intake air.

Step 7. Slip the roof ashing over the pipe section(s) pro-
truding through the roof. Use a non-hardening sealant be-

tween the roof ashing and the roong to prevent water
leakage. Secure the base of the roof ashing to the roof
with roong nails. Ensure the roong material overlaps

the top edge of the roof ashing. (Fig. 38) Verify that you

have at least the minimum clearances to combustibles at

the rooine and in the attic.

Step 8. Continue to add pipe sections until the height of
the system (before adding the cap) meets the minimum
building codes require­ments as described
in Table 2, Figure 37.
Note that for steep

height must be in­creased. In high wind
conditions, nearby

the vent height or switching to the high wind termination
cap may help to solve the problem.

Step 9. Slip the storm collar over the pipe section, and

push it down to the top of the roof ashing. (Fig. 38) Use

non-hardening sealant between the storm collar and the
pipe section

Step 10. Holding the bottom of the termination cap only,
twist lock the cap onto the last pipe section protruding

above the rooine.

NOTES:

1. For multi-story vertical installations, a ceiling restop
is required at the second oor, and any subsequent
oors. (Fig. 39) Cut and frame a 9” x 9” (229 x 229 mm)
square opening for installation of the ceiling restop.

2. If vent passes through any occupied areas above the

rst oor, including closets and storage spaces, it must

be enclosed. The enclosure may be framed and cov­ered with sheet rock with standard construction materi­als, but required clearances to combustibles must be
maintained. Consult these installation instructions for
the minimum allowable clearances between the out-

3. If venting system passes through an attic space an at­tic insulation shield must be installed to prevent con­tact between pipe sections and the insulation. Nail the

base to oor of attic and adjust shield for appropriate

insulation level, then attach the collar at the top of as­sembly. (Fig. 39) For vaulted ceilings, the attic insu­lation shield cannot be installed. To prevent building
insulation and other debris from entering the support
box or contacting the pipe, a chase enclosure can be
constructed around the support box. Ensure proper
clearance to combustibles are maintained.

Cathedral Ceiling Installation

Step 1. Follow installation Step 1 and 2 under Vertical

Termination.

Step 2. Using the plumb bob, mark the centerline of the
venting system on the ceiling and drill a small hole through
the ceiling and roof at this point. From the roof, locate the
drill hole and mark the outline of the Cathedral Ceiling
Support Box.

Step 3. Remove shingles or other roof covering as neces­sary to cut the rectangular hole for the support box. Cut
the hole 1/8” (3 mm) larger than the support box outline.

Step 4. Lower the support box through the hole in the roof
until each side of the bottom of the support box protrudes
at least 2” (51 mm) below the ceiling. (Fig. 40) Align the
support box both vertically and horizontally with a level.

Temporarily tack the support box in place through the in­side walls and into the roof sheathing.

Step 5. Using tin snips, cut the support box from the top

corners down to the rooine, and fold the resulting aps
over the roof sheathing. The aps may be trimmed as

needed. (Fig. 41) Before nailing it to the roof, run a bead
of non-hardening sealant around the support box to make
a seal between the support box and the roof. Clean out
any combustible material from inside the support box.

Step 6. Follow Steps 4 and 5 of the Vertical Installation
instructions.

Step 7. Place the support clamp (provided with the sup­port box) inside the support box (at the bottom), and se­cure to the pipe section. The clamp allows the support
box to support the weight of the pipe sections. Continue to

add pipe sections until you are above the rooine.

General Maintenance

Conduct an inspection of the venting system annually.
Recommended areas to inspect are as follows:

1. Check areas of the venting system which are exposed
to the elements for corrosion. These will appear as rust
spots or streaks, and in extreme cases, holes. These
components should be immediately replaced.

2. Remove the vertical terminations cap and shine a

ashlight down the vent. Remove any bird nests, or

other foreign material.

3. Check for evidence of excessive condensation, such
as water droplets forming in the inner liner, and subse­quently dripping out at joints. Continuous condensate

can cause corrosion of caps, pipe and ttings. It may

be caused by having excessive lateral runs, too many
elbow and exterior portions of the system being ex­posed to cold weather.

4. Inspect joints to verify that no pipe sections or ttings

have been disturbed or loosened. Also check mechan­ical supports such as wall straps or plumbers tape for
rigidity.

Supplemental Canadian Instructions

When installing DirectVent Pro on appliances in Canada,
a 2-piece decorative wall thimble is required in order to
comply with IR #41. (Fig. 18 and 20) Install galvanized
exterior wall thimble plate on exterior of building and black
decorative wall thimble plate on the interior side of wall.
Install wall thimble centered through a square framed
opening in wall. Be sure to maintain all minimum clear­ances. When installing DirectVent Pro vertically through

oors, a ceiling restop is required at every oor/ceiling

level.

Vertical Through Existing Chimney

The heater must be vented to the outdoors through an ex-

isting masonry or prefabricated replace chimney system

through the roof.

The heater is approved to be vented to the outdoors through

any solid-fuel replace chimney that has been constructed

or installed in accordance with the national, Provincial/State
and local building codes and is constructed of noncombus­tible materials. For Venting Requirements, refer to page

10. Refer to Venting Components on page 14.

Converting a Class-A Metal Chimney or Ma­sonry Chimney to a Direct Vent System

Application

These instructions apply to the DuraVent Direct Vent Con­version kits for factory-built Class-A metal chimneys and
masonry chimneys. These venting systems, in combination
with the gas appliance, have been tested and listed by a
major testing agency such as UL, AGA, Omni or Warnock
Hersey. Check the manufacturer’s rating plate and instruc-

tion manual to conrm that a DuraVent Direct Vent Chimney

Conversion system is approved for use on the brand name

Installation Precautions

The DuraVent Direct Vent System is an engineered product
that has been designed and tested for use with an approved
list of direct vent gas appliances. The DuraVent warranty will

be voided, and serious re, health or other safety hazards

may result from any of the following actions:

to factory-built metal ceiling-supported type systems
and masonry through-the-wall type systems. NOTE:
You cannot install a Conversion Kit in a through-the­wall type factory-built metal chimney.

General Installation

Two different types of direct vent conversion systems are
described here. One is through an existing factory-built
metal chimney going through the ceiling. The other is
through the wall of an existing masonry chimney. Follow
the appropriate directions for your situation.

A typical direct vent conversion of a factory-built metal
chimney is shown in Figure 43. The concept of the direct
vent conversion is to connect an adapter to an Underwrit-

ers Laboratories listed 4” diameter aluminum ex pipe
(DuraVent’s DuraFlex is an example of a UL listed ex
pipe). The ex is then passed down through the center of

the existing metal chimney system. Three sizes of termi-

nation caps are available which should t most sizes and

makes of metal chimney systems. The Retro Connector

(909B) is then attached to the bottom of the ex pipe. Both

the cap adapter and retro connector are attached to the
existing chimney with sheet metal screws. The appliance
is then connected to the chimney with appropriate black
direct vent pipe and an adjustable length section.

A typical conversion of an existing masonry chimney is
shown in Figure 45. For installation through the wall of
an existing masonry chimney, a cap adapter (985K) and

ashing are used at the top of the masonry chimney. The 4”

aluminum liner is connected to the adapter and is passed
down the chimney and out through the masonry wall. This
is attached to the retro connector (909B) which is in turn,
attached to the masonry wall and is then connected to the
direct vent pipe leading to the appliance.

• Installation of any damaged Direct Vent compo-

nent.

• Unauthorized modication of the Direct Vent Sys-

tem.

• Installation of any component part not manufactured

or approved by DuraVent.

• Installation other than as instructed by DuraVent and

the appliance manufacturer.

Consult your local building codes before beginning the
installation. Have the existing installation inspected by a

qualied chimney sweep or professional installer, prior to

converting to direct vent. The existing chimney system must
be in serviceable condition, and functionally sound. The

direct vent conversion described herein applies only

1. Remove the existing chimney cap.

2. Measure the distance from the top end of the chimney
to the bottom of the ceiling support box, add 3” to this

measurement and cut a section of 4” ex pipe to that
length (the ex should already be extended to its nominal

length).

3. Connect the end of the ex pipe section to the underside

of the cap adapter you have selected using three (3)
sheet metal screws. (Fig. 46)

4. Pass the ex pipe down through the center of the chim­ney system, and center the adapter on the top of the
chimney pipe. Drill four (4) 1/8” diameter holes through
the adapter and into the chimney top. Insure that you are
in fact, drilling into the metal on the chimney. Twist-lock
the termination cap (980, 991 or 930) onto the adapter.

center the retro connector and attach it to the support
box or decorative sleeve for double wall solid packed
pipe, with the sheet metal screws furnished. The holes
in the retro connector are pre-punched. (Fig. 49)

7. The connection between the appliance and the retro
connector may be completed with sections of black
direct vent pipe, together with an adjustable length.

Installation Instructions for Converting a Ma­sonry Chimney

IMPORTANT: The existing masonry ue opening need to

have an area of at least 35 square inches (226 square mm)

to insure proper intake/exhaust ow.

1. Before cutting any holes, assemble the desired sections
of black direct vent pipe to determine the center of the
masonry penetration.

2. Once the center point of the penetration has been deter­mined, cut a 6” (152 mm) diameter hole in the masonry.
Be careful, if the hole is too large, the retro connector
might not mount properly. If the hole is too small, then
the appliance might starve for intake air. If there is a
frame wall in front of the masonry wall, cut and frame a
10” (254 mm) clear square opening in the wall (centered
around the 6” (152 mm) masonry opening). If there is
sheet rock only (no studs) in front of the masonry, the
10” (254 mm) clear opening is still needed, but does not
need to be framed. This allows the retro connector to
mount directly on the masonry and provide clearance
to the combustibles. (Fig. 54)

3. Secure the ashing (705C) to the top of the masonry

chimney using a bead of non-hardening sealant-adhe-

sive. If the ashing is larger than the top of the chimney,
then cut and fold ashing as needed to t chimney. (Fig.

50)

4. To determine the length of ex required, measure from 3”
(76 mm) above the top of the ashing down to the level

of the opening. Add to this measurement the distance
from the center of the chimney to out through the wall.

Cut a piece of 4” (102 mm) ex to this length (the ex

should already be extended to its nominal length).

5. Connect the 4” ex liner to the cap adapter (985K) using

three sheet metal screws. (Fig. 46)

6. Feed the 4” ex liner through the ashing into the chim-

ney. Continue to feed the liner out through the opening
in the masonry wall.

7. Secure the cap adapter to the ashing. Use three (3)

sheet metal screws through the side of the adapter

into the ange on the ashing as shown in Figure 51.

Twist-lock the termination cap (980,991, 930) on to the

(Fig. 52) Mount the retro connector to the masonry wall
using masonry bolts. Re-drill larger holes on connector
as needed. Be careful to insure that the connector is
centered in the opening and the mounting holes line up
with the masonry wall.

9. Slide the wall thimble cover (940) over the retro connector
and secure the with masonry bolts as shown in Figure

53. If you have a framed wall in front of the masonry,
use wood screws to mount the wall thimble cover to the
framed wall, over the retro connector and the 10” (254
mm) square framed opening as shown in Figure 54. If
needed, add a section of direct vent pipe to the retro
connector in order to extend through the opening in the
wall thimble cover.

A. Pilot ame may be too low or

blowing (high) causing the pilot
safety to drop out

B. Possible blockage of the vent

terminal

Corrective Action

Using a match, light pilot. If pilot lights, turn off pilot and
push the red button again. If pilot will not light - check
gap at electrode and pilot-should be 1/8” to have a
strong spark.

With the control knob in the pilot position, push the
control knob all the way and hold. Check for spark at
electrode and pilot. If no spark to pilot, and electrode
wire is properly connected, replace the battery in the
ignitor module and try again. Refer to Maintenance
Section. If the problem still exists, replace the ignitor
module box.

Check pilot ame. Must impinge on thermocouple/ther­mopile. NOTE: This pilot burner assembly utilizes both
a thermocouple and a thermopile. The thermocouple
operates the main valve operation (On and Off). Clean

and or adjust pilot for maximum ame impingement on

thermopile and thermocouple.

Turn valve knob to “Pilot”. Maintain ow to pilot; millivolt

meter should read greater than 10mV. If the reading
is okay and the pilot does not stay on, replace the gas
valve. NOTE: An interrupter block (not supplied) must
be used to conduct this test.

Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch.. If okay,
jumper wires across wall switch wires at valve, if burner
comes on, wires are faulty or connections are bad.

1. Be sure wire connections form thermopile at gas
valve terminals are tight and thermopile is fully
inserted into pilot bracket.

2. One of the wall switch wires may be grounded. Re­move wall switch wires form valve terminals if pilot
now stays lit, trace wall switch wiring for ground.

May be grounded to replace or gas supply.

3. Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
250-300 millivolts (minimum 150) while holding
valve knob depressed in pilot position and wall
switch “Off”. Replace faulty thermopile if reading is

below specied minimum.

Check burner orices for debris and remove.

Turn valve knob to “On”, place wall switch to “On”
millivolt meter should read greater than 150mV. If the
reading is okay and the burner does not come on,
replace the gas valve.

Clean and/or adjust pilot ame for maximum ame

impingement on thermopile and thermocouple.

Check the vent terminal for blockage (recycling the ue

gases).

Your Intrepid Gas Heater will provide years of service with
minimal upkeep. The following procedures will help ensure

that your stove continues to function properly.

Annual System Inspection

Have the entire heater and venting system inspected an-

nually by a qualied gas technician. Replace any worn or

broken parts.

Logset and Burner

Cleaning and Inspection

Cleanliness is critical to the proper function of the heater.
The logset and burner must all be kept free of dust and
unobstructed by debris. Inspect these areas before each
use and clean as necessary.

1. Turn the burner OFF and let the heater cool completely
before cleaning.

2. Remove the safety barrier and lift the stove front up, then
swing the bottom out to disengage it from the heater
shell. (Fig. 82)

3. Carefully remove the glass and frame assembly and

place it out of the way on a at, padded surface such

as a counter protected by a towel.

4. Carefully inspect the Logs for damage. Contact your
local dealer if any damage is evident. DO NOT OPER-

ATE THE HEATER WITH DAMAGED LOGS.

5. Use a soft bristled brush to sweep dust or debris from
the Logs, Pilot and Burner. Use care as the logs are
fragile and susceptible to damage.

6. Replace the glass panel and frame assembly.

7. Replace the Stove Front.

Intrepid® Direct Vent - Rear Vent Gas Heater

Cleaning the Glass

WARNING: Let the glass cool completely before
attempting to clean.

It will be necessary to clean the glass periodically. During
start-up, condensation, which is normal, forms on the in­side of the glass and causes lint, dust and other airborne
particles to cling to the glass surface. Also initial paint

curing may deposit a slight lm on the glass. It is therefore

recommended that the glass be cleaned two or three times
with a non-ammonia household cleaner and warm water

(we recommend gas replace glass cleaner). After that the

glass should be cleaned two or three times during each
heating season depending on the circumstances present.

Clean glass after rst two weeks of operation.

Glass Replacement

Care of Cast Iron

An occasional dusting with a dry rag will help keep the
painted surfaces looking new. Use high-temperature stove
paints, available through your local dealer, to touch-up ar­eas as needed. Clean areas to be painted with a wire brush
and be sure to cover the logs, burner and valve assembly,
glass and frame assembly. Apply the paint sparingly; two
light coats of paint will give better results than a single
heavy coat.

Clean porcelain enamel surfaces with a soft, damp cloth.
Do not use abrasive cleaning agents. If necessary, use only
a cleaning agent formulated especially for use on porcelain

enamel surfaces.

20306761

CAUTION

TURN THE PILOT OFF BEFORE PAINTING. ALLOW
THE HEATER TO COOL COMPLETELY BEFORE

PAINTING.

Replace glass only with Vermont Castings Group approved
parts. Refer to page 41 for replacement parts. Refer to
Figures 82 and 83 for removal of the damaged glass frame.

1. Remove the safety barrier by pulling gently on the

edges until the spring ngers release.

2. Open the swiveling latches (cams) on the top left
and right corners of the glass frame. Figure 82

3. Position the glass and frame against the rebox

by placing the bottom edge on the brackets on the

bottom face of the rebox.

4. Swing the assembly against the rebox, and close
the latches rmly against the pins protruding from
the rebox top.

37

Intrepid® Direct Vent - Rear Vent Gas Heater

Fig. 82 Remove the safety barrier and stove front.

Fig. 84 Wrap the gasket material around the outside edge of

the glass.

4. Apply a thin bead of high temperature silicone rubber
sealant along the inside corner of the glass frame, all

around the perimeter. Place the at gasketed side of

the glass panel back into the steel frame. Pinch the
rounded inside-facing gasket material to bulk it up.

5. Replace the glass frame and front panel as previously
described.

Inspect the Vent System Annually

Have the vent system inspected annually by a qualied

technician. Shut off the main gas supply before inspect­ing the system. Both the inner exhaust pipe and the outer

combustion supply pipe must be checked to conrm that

they are unblocked and in good condition.

NOTE: Shown without top for clarity.

Fig. 83 Release the latches to release the glass frame.

Gasket Replacement

The Intrepid Gas Heater uses a ‘tadpole’ type gasket to
seal between the glass panel and the frame. In time, this
gasket can become brittle and compressed and should be
replaced. New gasket is available from your dealer.

Shut off the gas supply and allow the stove to cool. Wear
safety goggles and a dust mask.

1. Remove the Front, Glass Frame and Glass Panel. (Figs.
81, 82) Remove the old gasket. Use a razor blade to
separate the glass and gasket from the frame, and
to clean the glass of any remaining cement or bits of
gasket. Use a cold chisel if necessary.

2. Determine the correct length of gasket by laying it out
around the edge of the glass. Allow an extra 1 - 2” (25­50 mm). Mark the spot to be cut. Use a utility knife.

3. Starting on a long edge, remove about 6” of the pro-

tective paper strip and apply the at adhesive face of

the gasket around the outside-facing edge of the panel.
Continue around the panel, applying about 6” at a time
and being careful to not stretch the material. Do not
overlap the gasket ends. (Fig. 84)

Check the Gas Flame Regularly

To ensure the stove is operating properly, check the ames
periodically to conrm they match page 31, Figure 66. The
ames will be blue during the rst 15-20 minutes of opera-

tion, and will gradually turn to yellow after that.

Do not use your stove if the ame pattern differs from that

shown here. Contact your Vermont Castings dealer or a

qualied technician for help.

Stove Disassembly

If there is eve r a n eed to remove the  reb ox as semb ly fr om
the stove shell, support the rebox with solid stands about

6” (152 mm) tall under the left and right outer edges of the

rebox base. Do not set the rebox assembly directly on
the oor; this can damage the control valve and/or the gas
lines from the valve to the rebox.

Before removing the rebox from the shell, disconnect the

on/off switch wires from the valve. If the assembly includes
the optional fan, disconnect the fan rheostat. If the installa­tion includes a wall thermostat, disconnect the thermostat
leads from valve.

Disconnection and reconnection to the gas line should only

be done by a qualied gas service technician.

Upon reinstallation, the vent system must be sealed to the

rebox as discussed in the venting section. Also be sure
the logs are placed in the rebox correctly, as shown on

page 29, Figures 58-61.

LIMITED LIFETIME WARRANTY

PRODUCT COVERED BY THIS WARRANTY
All Vermont Castings brand gas stoves, gas inserts, and gas replaces installed in the United States of America
or Canada.

LIMITED LIFETIME WARRANTY
Vermont Castings Group warrants that all cast iron parts, the

combustion chamber, ceramic burner, and heat exchanger of every
Vermont Castings gas product will be free of defective material
or workmanship during the period the product is owned by the
original owner subject to proof of purchase and the conditions and
limitations listed on this warranty document.

BASIC ONE-YEAR WARRANTY
Vermont Castings Group warrants to the original owner that your

COMPONENT WARRANTY LIMITATATIONS
PORCELAIN ENAMEL FINISHED PARTS: Vermont Castings Group

offers no warranty on chipping of enamel surfaces. Inspect all
products prior to accepting them for any damage to the enamel.

are not covered by warranty.

Glass is not covered for discoloration or stains due to environmental
issues, or improper cleaning and maintenance.

PLATED PARTS AND ACCESSORIES: Brass, nickel, and gold parts

should be cleaned with Lemon oil only. Commercial cleaners cannot

chemicals or down draft conditions.

supplied accessories are covered for a period of one year.
