Operating Instructions
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
dierent 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 73.
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 o 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.

cLeaning the gLass
When the replace has cooled, remove the face of the replace along with the glass. See section “Glass
Door Removal” on page 18. 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.

Turn the unit o and wait for it to fully cool down before proceeding. Both the safety screen and outer glass
are attached using four hooks. To remove, lift up to disengage the hooks from their attachment points and
pull away from the unit. See Figure 18 and Figure 19.
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 o 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 shown in section
“Installation of Log Set and Embers” on page 41. If new/more embers and rock wool are required, contact
your nearest ENVIRO dealer.
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 section “Parts List” on page 47). 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. See section “Glass Door Removal” on page 18
• 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.
