CLEANING
AND
MAINTENANCE
Clean the ceramic glass periodically. Condensation will some-
times form on the glass during a cold startup. This is normal for
all gas fireplaces and inserts. This condensation often attracts
dust and lint to the surface of the glass. The initial paint curing
of the appliance can also leave a slight film on the glass. This
is a temporary problem.
Your should clean the glass after the first two weeks of use. After that, you should clean the glass no more than two or
three times a season. Use a mild glass cleaner to clean the door. Do not use abrasive cleaners. They will damage the glass
surface.
Let glass cool before cleaning. Do not
clean glass when it is hot. Damage
could occur.
CAUTION
Make sure the gas valve knob is in the “OFF” position. Wait at least five (5) minutes before start-
ing maintenance.
VENTING SYSTEM
A qualified agency should examine the venting system annually.
