When first lighting the appliance, it will take a
few minutes for the line to purge itself of air.
Once purging is complete, the pilot and burner
will light and operate as indicated in the instruc-
tion manual.
Subsequent lighting of the appliance will not
require such purging. Inspect the pilot flame (re-
move logs, if necessary, handling carefully).

The pilot flame should be steady, not lifting
or floating. Flame should be blue in color with
traces of orange at the outer edge.
The top 3/8" (10 mm) at the pilot generator
(thermopile) and the top 1/8" minimum (tip)
of the quick drop out thermocouple should be
engulfed in the pilot flame.
The flame should project 1" (25 mm) beyond the
hood at all three ports (see Figure 57). Replace
logs if removed for pilot inspection.
To light the burner; turn "ON" the remote wall
switch and rotate the gas valve control knob
counterclockwise to the "ON" position ("ON"
will be at the top side of the valve).
