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" (26 mm) beyond
the hood at all three ports
(see
Figure 18
)
.
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).

Step 7. VERIFYING APPLIANCE OPERA-
TION
Turn on burner and observe the individual
tongues of flame on the burner. Make sure
all ports are open and producing flame evenly
across the burner. If any ports are blocked, or
partially blocked, clean out the ports.
With gas line installed run initial system
checkout before closing up the front of the
unit. Follow the pilot lighting instructions
provided in the Installation and Operation
Instructions manual. For piezo igniter loca-
tion see
Figure 17
(millivolt appliances only).
NOTE:
Lighting Instructions are also found on
the literature tag tied to the gas piping next
to the gas valve. To access the tag, open the
lower control compartment door
(Figure 17)
by
pushing in simultaneously the left and right top
corners of the door. (The door is hinged at the
bottom). Remove the bottom compartment door
by sliding the hinge pin, located at the door’s
left side, to the right until it disengages from
the left corner post hole. Remove the modesty
panel. To remove the modesty panel, slide the
panel forward until it contacts the cabinet bot-
tom panel, then lift straight up and tilt forward.
Remove the modesty panel carefully, so that
none of the wires become loose or disconnected.
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).
