BURNER INJECTOR HOLDER AND
The primary air inlet holes allow the proper
amount of air to mix with the gas. This pro-
vides 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 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. 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 injector holder for dust and dirt
(see Figure 33).

CLEANING
3. Blow air through the ports/slots and holes
in the burner.
4. Check 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 ame indicates 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 Figure
34). With unit off, lightly blow air through the
air inlet hole. You may blow through a drinking
straw if compressed air is not available.
