Figure 3. Pilot Flame
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.
Gas valve
regulator
Gas valve
Primary air
adjustment rod
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.

Operating Instructions
For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
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.
NORMAL SOUNDS DURING OPERATION:
Table 2: Normal Sounds
Component Sound & Reason
Westport Creaking when heating up or cooling down.
Burner Light pop or poof when turned off; this is more common with LP units.
Temperature Sensor Clinking when it senses to turn the blower on or off.
Pilot Flame Quiet whisper while the pilot ame in on.
Blower / Fan Air movement that increase and decreases with the speed of the blower. The
blower is pushing the heat from the replace into the room.

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
Location.
