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 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 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 49).
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 as-
sembly. There is a small pilot air inlet hole about two
inches from where the pilot flame comes out of the
pilot assembly (see Figures 50 or 51 depending on
model). 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.
