aiR shutteRs:
Behind the valve access door is the air shutter adjustment levers on the right hand side of the venturi box
(see Figure 4) above the control panel. The air shutters allow the amount of air coming into the replace
to be adjusted in order to accommodate different climates and venting arrangements. The left shutter
adjusts the rear burner and the right shutter adjusts the front burner. 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 44, page 35.
Thermocouple
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,
Rear Burner
Less Air

the replace is getting too much air. Therefore, the air shutter should be closed (pushed in) slightly until
the correct ames are achieved. Flames that are very orange, with tall, dark, stringy tips, are not getting
enough air. Open (pull out) the venturi until the ames clean up. If the shut is opened, or closed all the
way, and the correct ames cannot be attained, turn off the gas and contact the dealer.
Warning: Incorrect shutter 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 sufcient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specically 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
qualied agency.
cLeaning DecoRative suRfaces:
Painted, powder coated, or porcelain enameled surfaces should be wiped with a damp cloth periodically.
Never clean the face when it is hot. Do not use other cleaners as they may leave a residue, which can
become permanently etched into the surface.
10
Maintenance And Service
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 painted 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. Carefully clean any dust off the logs and remove
any lint from the burner and pilot. At this time, inspect the ceramic burner for cracking. 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 as shown in the seconDary InstallatIon - log
set InstallatIon section. If any logs are damaged, contact your nearest ENVIRO dealer.
RePLacingthe 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). Wear gloves when handling damaged glass door assembly
to prevent personal injury. 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 qualied service person.
The glass must be purchased from an ENVIRO dealer. No substitute materials are allowed.
Remove the door (see page 12). The replacement glass will come with a new gasket installed. Remove
any silicone remnants from the door. Apply high temperature silicone to the two vertical faces of the
door and install the new piece of glass with gasket (be sure to maintain edge clearances). Apply even
pressure to the glass to allow the silicone to adhere to the gasket material.
