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, and lint. Clean these
air inlet holes prior to each heating season.
Blocked air holes will create soot. We rec-
ommend that you clean the unit every 2,500
hours of operation or every three months.
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. You can use a vacuum cleaner in the
blow position. 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 damage the pilot assembly.
1.
Shut off the unit, including the pilot.
Allow the 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 39).
3.
Blow air through the ports/slots and
holes in the burner.
4.
Check the injector holder located at the
end of the burner tube again. Remove any
large particles of dust, dirt, lint, or pet hairs
with a soft cloth or vacuum cleaner nozzle.

Burner Tube
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 flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about two inches from where the pilot flame
comes out of the pilot assembly (see Figure 40).
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.
