INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the
proper flame height. Alterations may have
occurred during shipping and handling. Call
a qualified service person to readjust the
pilot if necessary.
The height of the thermopile must be 3/8" to
1/2" above the pilot flame as shown in Figure
58. The thermocouple must be at a height of
about 1/8" above the pilot flame. The flame
from the pilot burner must extend beyond
both the thermocouple and thermopile.
If your pilot assembly does not meet these
requirements:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 26)
• see Troubleshooting, pages 31 through 34
BURNER FLAME PATTERN
Burner flames will be steady; not lifting or
floating. Flame patterns will be different
from unit to unit and will vary depending on
installation type and weather conditions.
If the vent configuration is installed incor-
rectly, the flames will lift or "ghost". This
can be dangerous. Inspect the flames after
installation to ensure proper installation and
performance.

OPERATING
BLOWER
Locate the blower controls by opening
the lower louver panel on the fireplace.
Blower controls are located on the left
side of the switch bracket to the left just
inside the louver panel.
The GA3700 manual blower has an ON
setting and an OFF setting. The blower
will only run when the switch is in the ON
position. In the OFF position, the blower
will not operate.
The blower helps distribute heated air
from the fireplace. Periodically check the
louvers of the firebox and remove any
dust, dirt, or other obstructions that will
hinder the flow of air.
REMOTE
OPERATION
Follow instructions included with the re-
mote control.
NOTICE: You must light the pilot
before using the hand-held re-
mote control unit. See
Lighting
Instructions, page 26.
1. After lighting, let pilot flame burn for
about one minute. Turn gas control
knob on the control valve to ON posi-
tion. Turn variable control knob any-
where between HI and LO. Slide the
selector switch to the REMOTE po-
sition.
Note: The burner may light if
hand-held remote ON button was on
when selector switch was last turned
off. You can now turn the burners on
and off with the hand-held remote con-
trol unit.
IMPORTANT: Do not leave the se-
lector switch in the REMOTE posi-
tion when the pilot is not lit. This will
drain the battery.
IMPORTANT: Be sure to press the
ON/OFF button on the hand-held re-
mote control unit for up to 3 seconds
to assure proper operation.
2. Press the ON/OFF button to turn the
burners on and off. When turning
burners off, the pilot will remain lit.
IMPORTANT: To turn the pilot off,
manually turn the gas control knob
on the heater to the OFF position.
