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 13). 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).
Electronic Appliance Checkout
To light the burner, turn ‘ON’ the unit mounted
On/Off switch or the optional remote wall switch.
Ensure the igniter lights the pilot. The pilot
flame should engulf the flame rod as shown
in Figure 14.
