1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burners, pilot and primary air inlet
holes on injector holder for dust and dirt (see
Figures 40 or 41).
3. Blow air through the ports/slots and holes in
the burners.
4. Check the injector holders located at the end
of the burner tubes 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 holders.
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 42). With the unit
off, lightly blow air through the air inlet hole. The
access hole for propane/LP pilot is on the front of
the burner carriage as shown in Figure 42. The
access hole for natural pilot is behind the pilot
bracket on the top of burner carriage (see Figure
41). You may blow through a drinking straw if
compressed air is not available.
