Checking the System

1. PURGING THE GAS LINE: When lighting the appliance
for the first time it will take a few moments to clear
the gas line of air. Once this purge is complete, the
appliance will operate as described in the lighting
instructions located on the insert's rating plate and
back cover of this manual. All subsequent lightings
of the insert will not require such purging of the gas
line.
2. PILOT FLAME: The pilot flame should be steady, not
lifting or floating. The flame should be blue in color
around the pilot hood, , , , , with traces of yellow toward
the outer edges. It is imperative that the pilot flame
engulf the top 3/8" of the thermopile (power genera-
tor) and the top 1/8" of the quick drop out thermo-
couple. The pilot flame should project out of the
pilot hood 1" at all three ports. See Figure 28.

3. BURNER ADJUSTMENT: The burner is equipped with a
variable gas control valve. This valve provides easy
adjustment of the flame height appearance and heat
output. To adjust the flame between the HI and LO
setting, rotate the HI/LO knob, located in the center
of the valve face. Flame height will adjust approxi-
mately 1.0" to 1.5" between the HI and LO settings.
NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK LOG
PLACEMENT IF ANY SOOT OR SMOKE IS APPARENT. IF
SOOT OR SMOKE PERSIST, THE AIR SHUTTER MAY
REQUIRE ADJUSTMENT.
DO NOT ATTEMPT TO ALTER THE FLAME APPEARANCE BY
POSITIONING THE GAS VALVE IN ANY OTHER POSITION
OTHER THAN THE FULL "ON" POSITION.
