CLEANING AND MAINTENANCE
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 burner repeat steps 3 and 4.
Clean pilot assembly also. A yellow tip on
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 38). 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.

Periodically inspect all burner ame holes
with heater running. All slotted burner ame
holes should be open with yellow ame pres-
ent. All round burner ame holes should be
open with a small blue ame present. Some
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner ame holes will create soot.
WARNING: Turn off heater

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 in-
let 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 qualied 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 com-
pressed air in a can, please follow the directions
on the can. If you don’t follow directions on the
can, you could damage 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 37).
3. Blow air through the ports/slots and holes
in the burner.
4. Check injector holder located at end of
burner tube again. Remove any large
