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
seconDary InstallatIon - log set anD ember InstallatIon section. If new/more embers and rock wool are
required, contact your nearest ENVIRO dealer.

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). 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 qualied
service person. The glass must be purchased from an ENVIRO dealer. No substitute materials
are allowed.
