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,
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 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 com-
pressed air in a can, please follow the directions on
the can. If you donʼt 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 43 and 44).

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.

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 two inches from where the pilot flame comes out of the pilot assembly (see Figure 44). 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.
