4. Check orifice 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
orifice holder.
6. In case any large clumps of dust have now
been pushed into the burner repeat steps
3 and 4, beginning on page 21.
Clean 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 25). 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.

GLASS PEBBLES
• If you remove glass pebbles for cleaning,
refer to
Installing Glass Pebbles
, page 17,
to properly replace glass pebbles.
• Replace glass pebbles if broken.
MAIN BURNER
Periodically inspect all burner flame holes
with the heater running. All burner flame holes
should be open. Some burner flame holes
may become blocked by debris or rust, with
no flame present. If so, turn off heater and let
cool. Remove blockage, blocked burner flame
holes will create soot.
