For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY A FIRE OR EXPLOSION MAY
RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OF LOSS OF LIFE.
PILOT LIGHTING INSTRUCTIONS:
Operating Instructions
PILOT LIGHT:
1. Turn off the gas to the fireplace. If not recently done, remove the glass and let the unit air
out for at least five (5) minutes to clear out any gas. Turn on gas to the heater. Leak test all joints
with soapy water. NEVER USE OPEN FLAME FOR LEAK TESTING.
2. Start the pilot by pressing the gas control knob and turning it to PILOT.
While holding the gas control knob in, press the piezo ignitor several times
until the pilot light starts. Hold the gas control knob in for 30 seconds.
Check that the pilot has fully engulfed the thermocouple assembly (see
Figure 4).
����������
������������
3. Start the main burner by turning the gas control knob to ON and then
turn the rocker switch to ON. Check that all burner ports have flame.
4. Leak test all gas joints again.
Figure 4. Pilot Flame
AIR SHUTTER:
The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in
Figure 5.
The air shutter allows the amount of air coming into the fireplace to be adjusted in order to accommodate
different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot
flame is burning normally and none of the burner ports are plugged. Let the fireplace burn for roughly
fifteen minutes and then examine the flames, compare the flames to Figure 55.
The ideal flame will be blue at the base and light
orange above. The flames should be of medium
height. If the flames look like this, no venturi
adjustment is needed. If the flames are fairly
short and mostly blue, the fireplace is getting
too much air. Therefore, the air shutter should
be closed slightly until the correct flames are
achieved. Flames that are very orange, with
tall, dark, stringy tips, are not getting enough air.
Open the venturi until the flames clean up. If the
venturi is opened, or closed all the way, and the
correct flames cannot be attained, turn off the
gas and contact the dealer.

Maintenance And Service
ROUTINE MAINTENANCE:
At least once a year, run through the following procedures to ensure the system is clean and working
properly. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not
blocked by anything. The pilot flame should be blue with little or no yellow on the tips.
Warning: Clearances must be sufficient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specifically approved with this appliance may result in property damage or personal injury.
The venting system must be periodically examined; it is recommended the examination is done by a
qualified agency.
CLEANING THE GLASS:
When the fireplace has cooled, remove the face of the fireplace along with the glass. See MAINTENANCE
AND SERVICE - GLASS DOOR REMOVAL. Check the gasket material on the back of the glass, making sure that it
is attached and intact.
During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all
fireplaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint
curing of the appliance can leave a slight film behind the glass, a temporary problem. The glass will need
cleaning about two weeks after installation. Use a mild glass cleaner and a soft cloth; abrasive
cleaners will damage the glass and plated surfaces. Depending on the amount of use, the glass
should require cleaning no more than two or three times a season. Do not clean the glass when it is
hot.
CLEANING THE FIREBOX:
Remove the logs carefully, as they are very fragile. Gently remove all the embers and rock wool and
place on a paper towel. Vacuum the bottom of the firebox thoroughly. Carefully clean any dust off the
logs and remove any lint from the burner and pilot. At this time, inspect the burner pan for cracking or
severe warping. If a problem is suspected, contact the dealer. Check the logs for deterioration or large
amounts of soot; a small amount on the bottom side of the logs is normal. Replace the logs and embers
as in the LOG SET AND EMBER INSTALLATION section. If new/more embers and rock wool are required, contact
your nearest ENVIRO dealer.
CHANGE BATTERY IN IGNITION MODULE:
If the unit does not spark when lighting, the battery in the
electronic ignition could need replacing.
Located on the left hand rear corner of the unit is a small
rectangular hole. Located here is the electronic ignition module
(see Figure 6). Remove the battery cover, located on the left side
of the module, and replace the AA battery.
Reinstall the battery cover and check for spark by depressing the
pilot knob located on the control panel.

Maintenance And Service
REPLACING THE GLASS:
The glass in the fireplace is a high temperature ceramic. If the glass is damaged in any way, a factory
replacement is required (see PARTS LIST - COMPONENTS). Wear gloves when handling damaged glass door
assembly to prevent personal injury. When the glass door assembly is being transported, it must be
wrapped in newsprint and tape and/or a strong plastic bag. Do not operate with the glass front removed,
cracked or broken. Removal and replacement of the glass from the door must be done by a licensed or
qualified service person. The glass must be purchased from an ENVIRO dealer. No substitute
materials are allowed.
To Replace:
• Open door, and remove the glass carefully.
• Install the new piece of glass with the large bulb in the gasket tape against the unit. Place the joint in
the tape in a bottom corner. Close door.
OPENING THE DOOR:
Turn unit off and wait until the appliance has cooled down. Remove the cast iron top from the unit by lifting
straight up. Lift the two door handles located on either side of the door and lift the glass door assembly
straight up and out (see Figure 7 and 8). Carefully open the two doors and remove if necessary.
Ensure the door is properly fastened after cleaning before attempting to re-light the appliance.

This fireplace have been tested and certified for use with SIMPSON DURAVENT TYPE GS PIPE FOR GAS
STOVES. SELKIRK DIRECT-TEMP SYSTEM SECURITY CHIMNEY’S “SECURE VENT DIRECT VENT SYSTEM”
and SELKIRK “METALBESTOS MDV VENT SYSTEM” kits are available for horizontal venting. When using
Simpson Duravent, it is recommended that, before installation, a bead of RTV High Temperature Silicone
should be applied to each outer vent joint, and Mil-Pac to each inner joint. When planning an installation,
it will be necessary to select the proper length of vent pipe for the particular requirements.
A MINIMUM VERTICAL LENGTH OF 24” (61 cm) TO THE FIRST 90° ELBOW IS REQUIRED.
WITH THIS MINIMUM VERTICAL RISE, HORIZONTAL RUNS OF FROM 1 FT (30.5 cm) to 3 FT (91.5 cm)
ARE PERMITTED TO REACH THE OUTSIDE VENT TERMINATION.
BEFORE BEGINNING THE INSTALLATION TAKE CARE TO ENSURE AN APPROPRIATE OUTSIDE LOCATION
FOR THE VENT TERMINATION CAN BE ACCOMMODATED. FOLLOW THE VENT LENGTH DIAGRAM
PRECISELY.
VENTING TERMINALS CANNOT BE RECESSED INTO A WALL OR SIDING.
If extra elbows are being used, overall allowable length will be reduced by 3 ft (91.5 cm) per
additional elbow.
WARNING: Do not mix parts from different vent manufacturers’s systems.
EXCEPTION TO WARNING: This product has been evaluated by Intertek for using a Direct Vent GS
starting collar in conjunction with Secure Vent, Direct-Temp, and Ameri Vent Direct venting systems. Use
of these systems with the Direct Vent GS starting collar is deemed acceptable and does not affect the
Intertek WH listing of the appliance.
VENT CONFIGURATIONS AND RESTRICTOR SETTINGS:
Figures 12 shows the range of venting options, it shows possible vent configurations if the unit is top
vented, for vertical and horizontal terminations, any layout that remains within the shaded area is
acceptable. Having the fewest number of elbows is ideal, as they tend to disrupt air movement. Using
45˚ elbows is preferable to using 90˚ elbows. Also, a shorter vent system will perform better than a
longer one.
The ENVIRO WESTPORT has been designed with a built in restrictor plate. The restrictor is designed to
enhance flame appearance when installing this unit with vertical chimneys as well as installations with
longer horizontal vent applications. It does this by controlling the amount of air moving through the vent
pipe.
Figure 12 shows the vent restrictor position required,
relative to the length of vent pipe. Longer vertical
vent lengths necessitate greater restriction; position
1 is open and position 5 is maximum restriction (refer
to Figure 11). To avoid injury, it is best to make this
adjustment when the fireplace is cool or use welder’s
gloves or oven mitts.
To access vent restrictor remove the valve cover plate
from the right rear corner of the unit by undoing the
two fastening screws.
Loosen the 1⁄4” hex head bolt and adjust to the correct
setting.

PLANNING YOUR INSTALLATION:
When planning your installation, it will be necessary to select the proper length of vent pipe for your
particular requirements. It is important to note when passing through a wall, the maximum allowable
wall thickness is 10 inches (25.4 cm), 11⁄2 inches (3.8 cm) clearance to combustibles must be maintained.
Select the amount of vertical rise desired for “vertical-to-horizontal” type installations. 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 through the attic or second story, and allow
for sufficient vent height above the roof line. For two story applications, a fire stop is required at each
floor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the
venting system to the appliance flue outlet, a twist-lock adapter is built into the appliance at the factory.
Refer to ‘Vent Configuration and Restrictor Settings’ for venting parameters.

HORIZONTAL INSTALLATION:
STEP 1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are
in the way when the venting system is attached. If this is the case, you may want to adjust the
location of the appliance.
STEP 2. Direct vent pipe and fittings are designed with special twist-lock connections. Assemble the
desired combination of black pipe and elbows to the appliance adapter with pipe seams oriented
towards the wall or floor, as much out of view as possible.
Place a bead of Mil-Pac on the outer edge of the inner exhaust pipe (non-flared end). Place a
bead of high temperature silicone on the male edge of the outer pipe. Push the pipe sections
completely together, then twist-lock one section clockwise approximately 1⁄4 turn, until the two
sections are fully locked. The female locking lugs will not be visible from the outside, on black
pipe. They may be located by examining the inside of the
female ends as shown in Figure 16.

every 36 inches (915 mm). Wall straps are available for this purpose, also when running horizontal pipe
minimum clearances to combustibles must be maintained; 2 inches (51 mm) at top, 11⁄2 inches (38
mm) at sides, 11⁄2 inches (38 mm) at bottom.
STEP 3. With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4 cm) x
10” (25.4 cm) square hole (refer to Figure 17). The center of the square hole should match the
center line of the horizontal pipe. Cut and frame the 10” (25.4 cm) x 10” (25.4 cm) hole in the
exterior wall where the vent will be terminated. Refer to Figure 8. If the wall being penetrated
is constructed of non-combustible material i.e. masonry or concrete, a 7 inches (17.8 cm) hole
is acceptable.
STEP 4. Position the horizontal vent termination in the center of the 10” (25.4 cm) x 10” (25.4 cm) hole,
and attach to the exterior wall with the
four screws provided. Before attaching

STEP 5. Before connecting the horizontal run of
the vent pipe to the vent termination,
slide the black decorative wall thimble
cover over the vent pipe.
STEP 6. Slide the appliance and vent assembly
towards the wall, carefully inserting the
vent pipe into the cap assembly. It is
important that the vent pipe extend into
the vent cap a sufficient distance with a
minimum of 11⁄4” (3.2 cm) overlap. Secure
the connection between the vent cap pipe
and the vent cap by attaching the two
sheet metal straps extending from the
vent cap assembly into the outer wall of
the vent pipe. Use the two sheet metal
screws provided to connect the straps
to the vent pipe. Bend any remaining
portion of the sheet metal straps back
towards the vent cap, so the decorative
wall thimble will conceal it (see left image
in Figure 18).
STEP 7. Slide the decorative wall thimble up
to the wall surface and attach with the
screws provided. Apply decorative brass
or chrome trim if desired (see right image
in Figure 18).

QUALIFIED INSTALLERS ONLY
NOTES:
(1) The four (4) wood screws provided should be replaced with the appropriate fasteners for stucco,
brick, concrete, or other types of siding.
(2) For buildings with vinyl siding, a vinyl siding standoff, should be installed between the vent cap and
the exterior wall (see Figure 19). Attach the vinyl siding standoff to the horizontal termination. The
vinyl siding standoff prevents excessive heat from possibly melting the vinyl siding material. Note
that the horizontal vent termination bolts onto the flat portion of the vinyl siding standoff (shaded
area in Figure 20), so that an air space will exist between the wall and the vent termination.
NOTES:
(1) The horizontal run of vent pipe must be level and should have a 1⁄4 inch rise for every one foot
of run towards the termination. Never allow the vent to run downward. This could cause high
temperature and may present the possibility of a fire.
(2) The location of the horizontal vent termination on the exterior wall must not be easily blocked or
obstructed. Refer to INITIAL INSTALLATION - VENT CONFIGURATIONS AND RESTRICTOR SETTINGS.
(3) When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).
(4) Maintain manufacturer’s clearances to combustibles with venting.
CORNER INSTALLATIONS:
Do not interfere with the structural integrity of the walls.
When rear venting if a 90° bend is used the maximum horizontal vent that can be used is 6” (152mm)
and if a 45° bend is used the maximum horizontal vent that can be used is 12” (305mm). For installations
with a 36” (915 mm) snorkel refer to Figure 21 and ‘Initial Installation - Installation of Rear Vented’.

VERTICAL INSTALLATION:
STEP 1. Check the 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.
STEP 2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to
the position of the appliance flue 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 the ceiling, mark the spot where the vent will penetrate the roof. Determine
if ceiling joists, roof rafters, or other framing will obstruct the venting system. You may wish to
relocate the appliance, or to offset, to avoid cutting load bearing members.
STEP 3. To install the Round Support Box/Wall
Thimble in a flat ceiling, cut a 10” square
hole in the ceiling, centered in the hole
drilled in Step 2. Frame the hole as shown
in Figure 23.

STEP 4. Assemble the desired lengths of black pipe
and elbows necessary to reach from the
appliance adapter up through the Round
Support Box. Insure that all pipe and
elbow connections are in their fully twistlocked position.
STEP 5. Cut hole in the roof centered on the small
hole placed in the roof from Step 2. The
hole should be of sufficient size to meet
minimum requirements for Clearance
to Combustibles, as specified. Continue
to assemble lengths of pipe and elbows

down to the roof level, as shown in Figure 24. Tighten the clamp around the pipe section. Use
a level to make sure the pipe is truly vertical. With roofing nails, secure the support straps to
the roof. Seal the nails holes heads with non-hardening mastic. Trim the excess length of the
support straps that extend out beyond the edge of the flashing.
STEP 7. Slip the flashing over the pipe section protruding through the roof. Secure the base of the
flashing to the roof with roofing nails. Use a non-hardening sealant between the uphill edge
of the flashing and the roof. Insure the roofing material overlaps the top edge of the flashing
as shown in Figure 24. Verify that you have at least the minimum clearance to combustibles at
the roof line.
STEP 8. Continue to add pipe sections until the height of the vent cap meets the minimum code
requirements. Refer to Figure 25 and Table 5. Note that for steep roof pitches, the vent height
must be increased. In high wind conditions, nearby trees, adjoining roof lines, steep pitched
roofs, and other similar factors can result in poor draft, or down drafting. In these cases,
increasing the vent height may solve the problem.
STEP 9. Slip the storm collar over the pipe, and push it down to the top of the roof flashing as shown
in Figure 24. Use the non-hardening sealant around the joint between the pipe and the storm
collar.

(1) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe
every 3 feet (91 cm), to avoid excessive stress on the elbows, and possible separation. Wall straps
are available for this purpose (see Figure 26).
(2) When ever possible, use 45° degree elbows instead of 90° degree elbows. The 45° degree elbow
offers less restriction to the flow of flue gases and intake air.
NOTES:
(1) For multi story installations. A ceiling firestop is required at the second floor, and any subsequent
floors (see Figure 27). The opening should be framed to 10” (25.4 cm) x 10” (25.4 cm) inside

CATHEDRAL CEILING INSTALLATION:
STEP 1. Follow installation steps 1 & 2 under INITIAL INSTALLATION - VERTICAL INSTALLATION.
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 coverings as necessary to cut the rectangular hole for the
“Support Box”. Cut the hole 1⁄8” larger than the “Support Box” outline.
STEP 4. Lower the “Support Box” through the hole in the roof until the bottom of the “Support Box”
protrudes at least 2 inches (5 cm) below the ceiling. Align the “Support Box” both vertically and
horizontally with a level as shown in Figure 28. Temporarily tack the “Support Box” in the 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 roof line, and fold the
resulting flaps over the roof sheathing (Figure 29). Before nailing it in to the roof, run a bead of
non-hardening mastic around the top edges of the “Support Box”, to make a seal between the
box and the roof. Clean out any combustible material from the inside of the “Support Box”.

GENERAL VENTING INFORMATION:
Canadian Installations
The venting system must be installed in accordance with the current CSA B149 installation code and/or
local codes having jurisdiction.
U.S.A. Installations
The venting system must be installed in accordance with the current National Fuel Gas Code, ANSI
Z223.1, and/or local codes having jurisdiction.
The minimum clearance to combustibles is 6” (150 mm) when using single wall venting and 1” (25 mm)
when using “B-vent” venting.
We strongly recommend installing an approved chimney liner in an existing brick chimney. This will
maximize the potential draft of the chimney and lessen the effects of slow chimney start-up.
VENTING OF A FIREPLACE FITTED WITH THE DRAFTHOOD ADAPTOR:
Note: Please refer to the chimney manufacturer’s installation instructions prior to commencing the
installation.
This unit may be vented to an existing masonry chimney, or where no masonry chimney is available, an
approved “B-vent” chimney, or any other approved constructed chimney/vent system (see Figure 40 & 41).
In either case, the fireplace may be connected to
the chimney/vent using a 4” (10 cm) single wall vent
connector.
�� ������
��������
����������
�����
�� ������
����
When an existing masonry chimney
is utilized for the venting, we
recommend the vent connector be
connected to an approved 4” (10
cm) diameter flue liner running the
full height of the chimney. In many
jurisdictions this flue liner may be
mandatory.
If 4” (10 cm) single wall vent is
used, a minimum of 6” (15 cm) must
be maintained between the vent
connector and any combustibles.
Figure 40: Unit top venting styles.
If 4” (10 cm) “B-vent” is used a minimum of 1” (25 mm) must be
maintained between the vent connector and any combustibles.
CAUTION: A minimum vent height of 12’ (3.6 m) from the floor is
required to effectively vent this fireplace.
Figure 41: Unit rear
venting style.

�� ��� ��� ��� ��
��������
SPILLAGE TEST:
A spillage test must be performed prior to leaving the installed fireplace
with the customer. Perform this test in the following manner:
1. Close all windows and doors in the room.
2. Start all exhaust fans in the house and the furnace blower.
3. Light the fireplace and set to maximum flame adjustment.
30
Figure 42: Draft test place.
Initial Installation
4. After a minimum of 10 minutes operation, test the chimney draft with a smoke match at the top row
of the pattern to confirm that there is adequate draft or ‘pull’ at the openings around the body of the
Drafthood Adaptor, as shown in Figure 42.
AUTOMATIC SAFETY SHUT DOWN:
If the spill switch is activated and shuts off the main burner the following procedure should be
followed.
• Is the pilot flame still on? If not, the reason for the fireplace shut down is not the spill
switch.
• Turn off the pilot flame and turn off all controls. Let fireplace to cool down.
• Check for blockages or restrictions in the flue and venting components.
• Restart the fireplace and check for vent draft as described earlier.
• Operate the fireplace in a normal manner.
• If the main burner shuts down again after a period of operation, turn off the fireplace and contact your
service technician.
SPILL SWITCH REPLACEMENT:
Use the following instructions to replace the
Safety Spill Switch.
1. Turn the unit off and allow it to cool.
2. Disconnect the spill switch wires from the
valve and on/off/remote rocker switch wire
(see Figure 40).
3. Remove the four mounting screws holding the
spill switch bracket and remove the bracket
(see Figure 43).
4. Remove and replace the spill switch with a
50-885 Spill Switch Assembly using a T-20
torx type driver.
5. Follow the reverse of the previous steps.
Figure 43: Spill switch installation.
OPTIONAL FINISHING:
In installations where the flue connector is running from the drafthood into a non-combustible chimney
the following optional finishing technique can be used.
CAUTION: Installations where the flue connector or venting connects to, or passes through,
combustible walls or ceilings, the inner vent components must be ‘B-vent’. It is not allowable
in these applications to use single wall inner vent components.
For decorative purposes a 6” (15 cm) single wall black stove pipe may be installed over the 4” (10 cm)
single wall or ‘B-Vent’.
Note: The use of these components is for aesthetic purposes only and does not effect the
fact that the fireplace, when fitted with the Drafthood Adaptor, is a Natural Vent appliance
and therefore draws air in through the Drafthood Adaptor intake ports.
