CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burners and
circulating 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,
bedding material, pet hair, etc.
BURNER INjECTOR HOLDER
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 heater
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 compressed 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
53).
3. Blow air through the ports/slots and holes in
the burner.
4. Check the injector holder located at the end
of the 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 the primary air holes on the
injector holder.
6. In case any large clumps of dust have now been
pushed into the burner repeat steps 3 and 4.
PILOT AIR INLET HOLE
Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet hole about
2" from where the pilot flame comes out of the
pilot assembly (see Figure 54). With the unit off,
lightly blow air through the air inlet hole. You
may blow through a drinking straw if compressed
air is not available. You may also clean the pilot
air inlet hole by pushing a common pipe cleaner
completely through the air inlet hole once.
