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 the burner repeat steps
3 and 4.
Clean the pilot assembly also. A yellow tip on
pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot flame comes
out of the pilot assembly (see Figure 41).
With unit off, lightly blow air through air inlet
hole. You may blow through a drinking straw
if compressed air is not available.

CAUTION: You must keep
control areas, burners, and
circulating air passageways
of heater clean. Inspect these
areas of heater before each use.
Have heater inspected yearly

CLEANING BURNER INjECTOR
HOLDER AND PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This provides
a clean burning flame. 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 qualified 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 Figures 40 and 41).
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
