-
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 qualied
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 orice holder for dust and dirt
(see Figure 35).
3. Blow air through ports/slots and holes in
burner.
