Figure 4. 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 5.
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 minutes and then examine the ames, compare the ames to Figure 55.
Gas valve
regulator
Gas valve
Primary air
adjustment rod
Figure 5: 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.

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 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. Figure 6: Electronic Ignition Module
Location.

Figure 8: Removing of Door.
Maintenance And Service
REPLACING THE GLASS:
The glass in the replace 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
qualied 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
