1. Shut off unit, including pilot. Allow 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 26).
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 inlet
hole about 2" from where the pilot flame comes
out of the pilot assembly (see Figure 27). 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.
