CARE 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. Inspect
these areas of heater before each use. Have heater inspected yearly by a qualified service technician.
Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
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 recommend that you clean the unit every 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, or you can use a vacuum cleaner in the blow posi-
tion. If using compressed air in a can, please follow the directions or on the can, or you could damage the pilot
assembly.
. Shut off the unit, including the pilot. Allow the unit to cool for at
least thirty minutes.
. Inspect burner, pilot, and primary air inlet holes on injector
holder for dust and dirt (see Figure 38).
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 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 indi-
cates 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 39). 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 Logs (page
6) to properly replace logs.
• Replace log(s) if broken or chipped (dime-size or larger).
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. All slot 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. Either remove the
blockage or replace the burner. Blocked burner flame holes will create soot.
