MAINTENANCE
Continued
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
35).
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 Figure 36). 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.
