8. In order to properly clean the burner and pilot as-
sembly, turn off the gas to the unit and remove the
logs exposing the burner and pilot assembly. Clean
all foreign materials from top of burner. Check to
make sure that the burner orifi ce is clean.
9. Visually inspect the pilot periodically. Brush or blow
away any dust or linen accumulations. If the pilot
orifi ce is plugged, disassembly may be required
to remove any foreign materials from the orifi ce or
tubing. When the appliance is put back in service,
check burner fl ame patterns. Flames should be
steady, not fl oating.
To obtain proper operation, it is imperative that
the pilot and main burner fl ame characteristics are
steady, not lifting or fl oating. Typically, the top 3/8
inch of the thermocouple should be engulfed in the
pilot fl ame (See Figure 54).
