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.
Clean the pilot assembly also. A yellow tip on the
pilot ame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet hole about
two inches from where the pilot ame comes out
of the pilot assembly (see Figure 40). 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.

CLEANING AND
MAINTENANCE
WARNING: Turn off replace
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and cir-
culating air passageways of
replace clean. Inspect these
areas of replace before each
use. Have replace inspected
yearly by a qualied service
person. Fireplace may need
more frequent cleaning due to
excessive lint from carpeting,
bedding material, pet hair, 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 ame. 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 qualied 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 Figures
39 and 40).
3. Blow air through the ports/slots and holes in
the burner.
