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 30 minutes.
2. Inspect burner, pilot and primary air inlet
holes on injector holder for dust and dirt
(see Figure 46).
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
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 flame indicates dust and dirt in
the pilot assembly. There is a small pilot air

You may blow through a drinking straw if
compressed air is not available.
