Operating Instructions
PiLot Light:
1. Turn off the gas to the replace. If not recently done, remove the glass and let the unit air out
for at least ve (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.
aiR shutteR:
The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in
Figure 4.
The air shutter allows the amount of air coming into the replace to be adjusted in order to accommodate
different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot
ame is burning normally and none of the burner ports are plugged. Let the replace burn for roughly
fteen (15) minutes and then examine the ames, compare the ames to Figure 61.

Figure 4: Gas Valve In Place on Unit.
The ideal ame will be blue at the base and light
orange above. The ames should be of medium
height. If the ames look like this, no venturi
adjustment is needed. If the ames are fairly
short and mostly blue, the replace is getting
too much air. Therefore, the air shutter should
be closed slightly until the correct ames are
achieved. Flames that are very orange, with tall,
dark, stringy tips, are not getting enough air.
Open the venturi until the ames clean up. If the
venturi is opened, or closed all the way, and the
correct ames cannot be attained, turn off the
gas and contact the dealer.
Warning: Incorrect venturi adjustment may lead
to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the
venturi adjustment.

Remote contRoLs (oPtionaL):
This replace can use an optional remote control or an optional cordless wall thermostat. If either of
these are to be used to control the replace for the majority of the time, leave the ON/OFF switch (on the
control panel) in the remote/thermostat position. Consult the instructions included with the remote/wall
thermostat for operation guidelines.
bLoweR sPeeD (oPtionaL):
The blower will come on only when the replace is up to temperature (approximately 20 minutes). The
speed of the fan can be changed by turning the fan control knob. To turn the blower off, turn the knob
COUNTER CLOCKWISE until it “clicks” off.
It is advisable not to operate the blower below 1/3 speed as it puts a strain on the windings of the blower
and running the blower at lower speeds could also cause premature fan failure.

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 ame should be blue with little or no yellow on the tips.
Warning: Clearances must be sufcient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specically 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
qualied agency.
cLeaning the gLass:
When the replace has cooled, remove the face of the replace 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
replaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint
curing of the appliance can leave a slight lm 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 rebox 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 5). 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. Figure 5: Electronic Ignition Module

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), 1½ 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 ue
outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow
for sufcient vent height above the roof line. For two story applications, a re stop is required at each
oor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the
venting system to the appliance ue outlet, a twist-lock adapter is built into the appliance at the factory.
Refer to initial inStallation - vent confiGuration and reStrictor SettinGS for venting parameters.

Figure 22: Restrictor plate settings.
The ENVIRO WESTPORT has been designed with a built in restrictor
plate. The restrictor is designed to enhance ame 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 23 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 22). To avoid injury, it is best to make this adjustment
when the replace is cool or use welder’s gloves or oven mitts.

vent conFiguRations anD RestRictoR settings:
Figures 23 & 24 show the range of venting options, they show possible vent congurations if the unit is
top vented (see Figure 23) or rear vented (see Figure 24), 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 appliance.
2. Direct vent pipe and ttings 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 oor, as much out of view as possible.
Place a bead of Mil-Pac on the outer edge of the inner exhaust pipe
(non-ared 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 ¼
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 25.
Notes:
(a) Twist-lock procedure: four (4) indentations, located on the female
end of the pipes and ttings, are designed to slide straight onto the
male ends of adjacent pipes and ttings, by orienting the four pipe
indentations so they match and slide into the four entry slots on the
male end.
(b) Horizontal runs of vent pipe must be supported every 36” (915mm).
Wall straps are available for this purpose, also when running horizontal
pipe minimum clearances to combustibles must be maintained;
2” (51mm) at top, 1½” (38mm) at sides, 1½” (38mm) at
bottom.
3. With the pipe attached to the stove in the correct location, mark the
wall for a 10” (25.4cm) x 10” (25.4 cm) square hole (refer to Figure
26). The center of the square hole should match the center line of
the horizontal pipe. Cut and frame the 10” (25.4cm) x 10” (25.4cm)
hole in the exterior wall where the vent will be terminated. Refer to
20
Figure 18. If the wall being
penetrated is constructed of
non-combustible material i.e.
masonry or concrete, a 7”
(17.8cm) hole is acceptable.
4. Position the horizontal vent
termination in the center
of the 10” (25.4cm) x 10”
(25.4cm) hole, and attach
to the exterior wall with
the four screws provided.
