Step 8. INSTALLING LOG SET, VOLCANIC
STONE AND GLOWING EMBERS
WARNING
Logs get very hot and will remain
hot up to one hour after gas supply
is turned off. Handle only when
logs are cool. Turn off all elec-
tricity to the appliance before you
install grate and logs.
WARNING
This appliance is not designed to
burn wood. Any attempt to do so
could cause irreparable damage
to the appliance and prove haz-
ardous to your safety.
WARNING
DO NOT attempt to install logs
until the appliance installation
has been completed, the gas line
connected and tested for leaks
and the initial burner operation
has been checked out.

To light the burner, turn ‘ON’ the OFF/ON switch
(located in the control compartment). Ensure the
igniter lights the pilot. The pilot fl ame should
engulf the fl ame rod as shown in Figure 51.
Observe the individual tongues of fl ame on
the burner. Make sure all ports are open and
producing fl ame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.
Step 7. CHECK APPLIANCE OPERATION
With the gas line installed, run initial system
checkout before closing up the front of the
appliance. Follow the pilot lighting instructions
provided in the Homeowner's Care and Opera-
tion Instructions. For piezo igniter location see
Figure 48 (millivolt appliances only).
Note: The (pull-out) Lighting instructions label
can be found in the control compartment
(see Figure 48).
When fi rst 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 instruction manual. Subsequent lightings
of the appliance will not require such purging.
Inspect the pilot fl ame.
Millivolt Appliance Checkout
The pilot fl ame should be steady, not lifting
or fl oating. 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" min (tip) of the
quick drop out thermocouple should be engulfed
in the pilot fl ame. The fl ame should project 1"
(25 mm) beyond the hood at all three ports
(Figure 50).
To light the burner; rotate the gas valve control knob
counterclockwise to the “ON” position then turn
“ON” the OFF/ON switch (installed at Step 4).
Observe the individual tongues of fl ame on
the burner. Make sure all ports are open and
producing fl ame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.

Note: The burners are not identical. Position them so
that the circular burner ports run as shown. Note
especially the vertical run of ports relative to the pilot
burner. Bracket A on the rear burner will interfere
with the pilot burner if an attempt is made to install
the rear burner in the front burner’s position.
