OWNER’S MANUAL
CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burners, and cir-
culating air passageways of
heater clean. Inspect these areas
of heater before each use. Have
heater inspected yearly by a quali-
fied service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,
bedding material, pet hair, etc.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If front burner flame
pattern shows yellow tipping, fol-
low instructions at bottom of this
page. Yellow flame on rear burner
is normal.
FRONT BURNER FLAME
PATTERN
Figure 26 shows correct front burner flame
pattern. Figure 27 shows incorrect front
burner flame pattern. The incorrect burner
flame pattern shows yellow tipping at top of
blue flame.
If front burner flame pattern is incorrect, as
shown in Figure 27
• turn heater off (see To Turn Off Gas to
Appliance [Thermostat-Controlled Mod-
els] page 15 or [Variable Manually-Con-
trolled Models] page 16)
• see Troubleshooting, pages 18 through 20
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles are burned
by heater, causing brief patches
of orange flame.

Installing Logs, page 13, to properly re-
place logs.
• Replace log(s) if broken or chipped
(dime-sized or larger).
CLEANING 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, and lint. Clean these
air inlet holes prior to each heating season.
Blocked air holes will create soot. We rec-
ommend that you clean the unit every 2,500
hours of operation or every three months.
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 28).
3. Blow air through the ports/slots and
holes in the burner.

Burner Tube
4. Check the injector holder located at the
end of the burner tube again. Remove any
large particles of dust, dirt, lint, or pet hairs
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 assembly. There is a small pilot air
inlet hole about two inches from where the
pilot flame comes out of the pilot assembly
(see Figure 29). 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.
