CLEANING AND
MAINTENANCE
WARNING: Turn off heater and let cool before
cleaning.
CAUTION: You must keep control areas, burner,
and circulating air passageways of heater clean. In-
spect these areas of heater before each use. Have
heater inspected yearly by a qualified service person.
Heater may need more frequent cleaning due to exces-
sive lint from carpeting, pet hair, bedding material, etc.
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, 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.
Note:
Removing the
rear panel and top grates of your stove will make cleaning easier.
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 26).
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 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 27). 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.

LOGS
• If you remove logs for cleaning, refer to Installing Gas Log
Heater Into Stove, page 10, to properly replace logs.
• Replace log(s) if broken or chipped (dime-sized or larger).
MAIN BURNER
Periodically inspect all burner flame holes with the heater running.
All slotted burner flame holes should be open with yellow flame
present. All round burner flame holes should be open with a small
blue flame present. Some burner flame holes may become blocked
by debris or rust, with no flame present. If so, turn off heater and let
cool. Remove blockage. Blocked burner flame holes will create
soot.
