CLEANING AND MAINTENANCE
4. Check orice holder located at end of
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 primary air holes on orice
holder.
6. In case any large clumps of dust have now
been pushed into burner repeat steps 3
and 4.
Clean pilot assembly also. A yellow tip on
the pilot ame indicates dust and dirt in pilot
assembly. There is a small pilot air inlet hole
about 2" from where pilot ame comes out
of pilot assembly (see Figure 36). With unit
off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if
compressed air is not available.

The primary air inlet holes allow proper
amounts of air to mix with 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 3 months during operation
and have heater inspected yearly by a qualied
service person.
We also recommend that you keep 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 unit, including pilot. Allow unit to
cool for at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet
holes on orice holder for dust and dirt
(see Figure 35).
3. Blow air through ports/slots and holes in
burner.
