CLEANING AND
MAINTENANCE
Continued
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 45 and 46).
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 assembly. 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
access 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.
