CLEANING AND MAINTENANCE
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 in
-
let 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. If using compressed air in a can, please
follow the directions on the can. If you don’t
follow directions on the can, you could dam
-
age the pilot assembly.
1. Shut off unit, including pilot. Allow 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 47).
3. Blow air through ports/slots and holes in
burner.
4. Check injector holder located at end of
burner tube again. Remove any large
particles of dust, dirt, lint, or pet hair with
a soft cloth or vacuum cleaner nozzle.
5. Blow air into primary air holes on injector
holder.
6. In case any large clumps of dust have now
been pushed into burner repeat steps 3
and 4.
Clean pilot assembly also. A yellow tip on pilot
flame indicates dust and dirt in pilot assembly.
There is a small pilot air inlet hole about 2" from
where pilot flame comes out of pilot assembly
(see Figures 48 or 49 depending on model).
With unit off, lightly blow air through air inlet
hole. You may blow through a drinking straw
if compressed air is not available.
