Intrepid® Direct Vent - Rear Vent Gas Heater
Vent Termination Clearances
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 influence 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 opening for inspection of vent pipe.
• Only venting components specifically approved and
labelled for this stove may be used.
• Minimum clearances between vent pipes and combustible 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.

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 finish. The galvanized pipe and fittings may
be used for concealed locations such as attics, or spaces
where corrosion is a factor, such as above the roofline.
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.

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 7). To determine the length of vent
pipe required for vertical installations, measure the distance from the appliance flue outlet to the ceiling, the ceiling thickness, the vertical rise in an attic or second story,
and allow for sufficient vent height above the roofline. For
multi-story applications, firestops are required at each
floor/ceiling level. If an offset is needed in the attic, additional pipe and elbows will be required.

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 first position the stove and measure to find 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 firestop plate to the sleeve end with
the holes. (Fig. 22) NOTE: The zero clearance sleeve

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 fittings are designed with
special twist-lock connections. To connect the venting
system to the appliance flue 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 floor, as much out of view as possible.
(Fig. 24)
Figure 24
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).
34
Wall straps can be usedSIMPTWISTLOCK
for this purpose. Alternatively,
plumbers tape or other suitable
noncombustible mate
rial 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.

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 trap3T
heat and become a posSIMPSONFRAMING
sible fire hazard.
17
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.

cap. Place the first 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, finally, attach the final 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) 2Z\x” (64 mm) screws provided. (Fig. 30)

3. When penetrating through stucco wall, install the
counter flashing. The counter flashing allows stucco,
or other materials, to be finished directly to the sides
of the termination cap. First attach the counter flashing to the base of the horizontal termination cap with
the small screws provided, then mount entire assembly onto the wall with the four (4) 2Z\x” (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 1Z\
v” (32 mm). Use the two (2) sheet metal screws provided
to secure the pipe section to the back of the termination
cap. The wall thimble cover will cover the screw heads.

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.

General Maintenance
Conduct an 34
inspection of the venting system annually.
Recommended areas to inspect are as follows:
TRIMCOLLAR
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
flashlight 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 fittings. It may
be caused by having excessive lateral runs, too many
elbow and exterior portions of the system being exposed to cold weather.
22
Vertical Through Existing Chimney
The heater must be vented to the outdoors through an existing masonry or prefabricated fireplace chimney system
through the roof.
The heater is approved to be vented to the outdoors through
any solid-fuel fireplace 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
Cathedral Ceiling Support Box
ST994
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
floors, a ceiling firestop is required at every floor/ceiling
level.
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 instruction manual to confirm that a DuraVent Direct Vent Chimney
Conversion system is approved for use on the brand name
appliance you have selected.
IMPORTANT
Read all instructions carefully before starting the installation. Failure to follow these instructions may create a
fire or other safety hazard, and will void the warranty.
Be sure to check the appliance manufacturer’s installation instructions for specific venting and clearance
to combustible requirements, which may vary from
one appliance to another.

be voided, and serious fire, health or other safety hazards
may result from any of the following actions:
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 Underwriters Laboratories listed 4” diameter aluminum flex pipe
(DuraVent’s DuraFlex is an example of a UL listed flex
pipe). The flex is then passed down through the center of
the existing metal chimney system. Three sizes of termination caps are available which should fit most sizes and
makes of metal chimney systems. The Retro Connector
(909B) is then attached to the bottom of the flex 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
flashing 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.

KIT 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
qualified 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
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.

Installation Instructions for Converting a Masonry Chimney
IMPORTANT: The existing masonry flue opening need to
have an area of at least 35 square inches (226 square mm)
to insure proper intake/exhaust flow.
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 flashing (705C) to the top of the masonry
chimney using a bead of non-hardening sealant-adhesive. If the flashing is larger than the top of the chimney,
then cut and fold flashing as needed to fit chimney. (Fig.
50)
4.To determine the length of flex required, measure from 3”
(76 mm) above the top of the flashing 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) flex to this length (the flex
should already be extended to its nominal length).
5. Connect the 4” flex liner to the cap adapter (985K) using
three sheet metal screws. (Fig. 46)
6. Feed the 4” flex liner through the flashing into the chimney.
26

problem
20012761
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.
A. Defective pilot generator (thermocouple), remote wall switch
Check pilot flame. 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 flame impingement on
thermopile and thermocouple.
B. Defective automatic valve
Turn valve knob to “Pilot”. Maintain flow 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.
A. Wall switch or wires defective
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.
B. Thermopile may not be generating sufficient millivoltage
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 fireplace 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 specified minimum.
C. Plugged burner orifice
Check burner orifices for debris and remove.
D. Defective automatic valve operator
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.
A. Pilot flame may be too low or
blowing (high) causing the pilot
safety to drop out
Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.

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 film 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 fireplace 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 first two weeks of operation.
Glass Replacement
Replace glass only with Vermont Castings Group approved
parts. Refer to Page 40 for Replacement Parts. Refer to
Figure 82 and previous instructions for removal of the
damaged glass frame.
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.
CAUTION
TURN THE PILOT OFF BEFORE PAINTING. ALLOW
THE HEATER TO COOL COMPLETELY BEFORE
PAINTING.

Inspect the Vent System Annually
NOTE: Shown without top for clarity.
Have the vent system inspected annually by a qualified
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 confirm that
they are unblocked and in good condition.
Check the Gas Flame Regularly
ST391a
Fig. 82 Release the latches to release the glass frame.
Gasket Replacement
To ensure the stove is operating properly, check the flames
periodically to confirm they match Page 31, Figure 65. The
flames will be blue during the first 15-20 minutes of operation, and will gradually turn to yellow after that.
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.
Do not use your stove if the flame pattern differs from that
shown here. Contact your Vermont Castings dealer or a
qualified technician for help.
Shut off the gas supply and allow the stove to cool. Wear
safety goggles and a dust mask.
If there is ever a need to remove the firebox assembly from
the stove shell, support the firebox with solid stands about
6” (152 mm) tall under the left and right outer edges of the
firebox base. Do not set the firebox assembly directly on
the floor; this can damage the control valve and/or the gas
lines from the valve to the firebox.
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.

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.
Stove Disassembly
Before removing the firebox 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 qualified gas service technician.
Upon reinstallation, the vent system must be sealed to the
firebox as discussed in the venting section. Also be sure
the logs are placed in the firebox correctly, as shown on
Page 29, Figures 58-61.

attach the shelf loosely to the stove, leaving the screws
loose enough to allow final adjustments. Then, position
the shelf and adjust the brackets so the shelf fits correctly.
Finally, tighten the screws.

or workmanship during the period the product is owned by the

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.

chemicals or down draft conditions.
