If an optional Wall Thermostat or Remote Control
Kit was purchased, intall it now, per instructions
provided in kit. See Figure 35. I
f a wall-mounted
thermostat is selected, mount it in a con-
venient location on a wall near the insert.
Wire the thermostat within the millivolt control
circuit using a maximum of 25 feet of 18 gage,
2 conductor wire. Caution: Do not connect the
optional wall thermostat, gas control valve or
control wiring system of the unit to a 120 volt
power supply (residential line voltage).
Step 17. CHECK BLOWER SYSTEM
OPERATION
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" minimum (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 39).

To reinstall glass door assembly panel, reverse
instructions on Step 5 (page 8).
When the insert heats up, the blower will auto-
matically be turned on by the fan disc, located
under the fi rebox bottom on the front left side.
It will come on at the speed determined by the
rheostat, located on left surround panel (see
Figure 37). To adjust the blower speed, dial the
rheostat to the desired speed setting. Rotate
the dial down (clockwise), just past the click
(the fi rst ON position) for the highest speed
setting. Turning the knob further clockwise
will provide slower blower speeds. Note: If
the rheostat is not turned “on”, the blower
will not operate.

WARNING: THE POWER CORD MUST BE
PLUGGED DIRECTLY INTO A PROPERLY
GROUNDED, 120 VOLT, 60 HZ, 3-PRONG
RECEPTACLE ELECTRICAL OUTLET. DO NOT
CUT OR REMOVE THE GROUNDING PRONG
FROM THIS PLUG. IT MUST BE ROUTED TO
AVOID CONTACT. DO NOT ROUTE POWER
CORD UNDER OR IN FRONT OF APPLIANCE.
With gas line installed run initial system
checkout before closing up the front of the
unit. Follow the pilot lighting instructions pro-
vided in the Homeowner's Care and Operation
Instructions (or pull out the instruction label
located in control compartment below glass
door assembly).
Step 15. CHECKING APPLIANCE OPERA-
TION
Step 13. INSTALL SURROUND KIT OR CON-
TROL KIT (see pages 12 & 13 in Homeowners
Manual).
Step 14. INSTALL WALL THERMOSTAT AND
REMOTE CONTROL (if purchased)
To light the burner, rotate the gas valve
control knob counterclockwise to the “ON”
position then turn “ON” the on/off switch
mounted on the surround assembly (see
Figure 37) or operate the burner with the
optional remote control, wall thermostat or
control switch.

Replace logs if removed for pilot inspection.
B. Light the appliance (refer to the lighting
instructions provided in the insert control
compartment and the Homeowner's Care and
Operation Instructions).
C. Brush all joints and connections with the
soapy water or leak detection solution to check
for leaks. If bubbles are formed, or gas odor is
detected, turn the gas control knob to the “OFF”
position and close the gas shut-off valve. Either
tighten or refasten the leaking connection and
retest as described above.
D. When the gas lines are tested and leak free,
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,
turn off unit, allow it to cool, then clean out
the ports.
E. Turn on gas supply and test for gas leaks using
a soapy water or gas leak detection solution.
Never use an open fl ame to check for leaks.
Step 12. TEST ALL CONNECTIONS FOR
LEAKS (FACTORY AND FIELD).
Test For Gas Leaks
A. Mix a 50% dish soap, 50% water solution
(or use a gas leak detection solution).
