natural gas supplier.
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 cre-
ate soot. We recommend that you clean the
unit every three months during operation
and have heater inspected yearly by a quali-
fied 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 recom-
mend using compressed air no greater than
30 PSI. Your local computer store, hard-
ware store, or home center may carry com-
pressed 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 direc-
tions on the can. If you don't follow direc-
tions 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 35).
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 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 36). 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.
