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
56. 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 25)
• see Troubleshooting, pages 28 through 30
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.

ACCESSORY
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.
Both the GA3700 manual blower and the
DA3610T thermostatically-controlled
blower have 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.
Note for CDA3610T Only:
If you are
using CDA3610T blower, your fireplace
and blower will not turn on and off at the
same time. The fireplace may run for
several minutes before the blower turns
on. After the heater modulates to the pilot
position, the blower will continue to run.
The blower will shut off after the firebox
temperature decreases.
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.
OPTIONAL REMOTE
OPERATION
Note:
The GHRC receiver and hand-
held remote control accessory must be
purchased separately. (See Accessories
on page 33.) Follow instructions included
with the remote control.
NOTICE: You must light the pilot
before using the hand-held re-
mote control unit. See
Lighting
Instructions,
page 25.
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.
