CLEANING AND MAINTENANCE
-
BURNER INjECTOR HOLDER AND
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 rec-
ommend that you clean the unit every three
months during operation, or as needed, and
have replace 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. 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 dam-
age 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 34).
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. Additional clean-
ing may be needed for proper pilot operation
based on use/lack of use. A yellow tip on the
pilot ame may indicate dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot ame comes out
of the pilot assembly (see Figures 35 or 36,
depending on model). 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.
