WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and cir-
culating air passageways of
fireplace clean. Inspect these
areas of fireplace before each
use. Have fireplace inspected
yearly by a qualified service
person. Fireplace may need
more frequent cleaning due to
excessive lint from carpeting,
pet hair, bedding material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
BURNER INjECTOR HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides
a clean burning flame. Keep these holes clear of
dust, dirt, lint, and pet hair. Clean these air inlet
holes prior to each heating season. Blocked air
holes will create soot. We recommend that you
clean the unit every three months during operation
and have fireplace inspected yearly by a qualified
service person.
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust and
dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store, or home center
may carry compressed air in a can. You can use a
vacuum cleaner in the blow position. If using com-
pressed air in a can, please follow the directions on
the can. If you don't follow directions on the can,
you could damage the pilot assembly.
1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet
holes on injector holder for dust and dirt (see
Figure 56, page 29).
