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 orifice holder for dust and dirt
(see Figure 30).
3. Blow air through the ports/slots and holes
in the burner.
4. Never inset objects into the pilot tube.
5. Blow air into the primary air holes on the
orifice holder.
Clean pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot

about 2" from where the pilot flame comes out
of the pilot assembly (see Figure 30). 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.
