CLEANING AND MAINTENANCE
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 person. Heater may need more frequent cleaning due to excessive lint from
carpeting, pet hair, bedding material, etc.
CAUTION
Turn off heater and let cool before
cleaning.
WARNING
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 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 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 injec-
tor holder for dust and dirt (see Figure 24).
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 ame
indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot ame
comes out of the pilot assembly (see Figure 25). 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.
