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 47). 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 carriange as shown in Figure 47. The ac-
cess hole for natural pilot is behind the pilot bracket
on the top of burner carriage (see Figure 47). You
may blow through a drinking straw if compressed
air is not available.
