Figure 32 - Correct Pilot Flame Pattern
Figure 33 - Incorrect Pilot Flame Pattern
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 32 shows a correct pilot flame pattern.
Figure 33 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not prop-
erly heating the thermocouple. When the
thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 33
• turn heater off (see To Turn Off Gas to
Appliance, page 15)

see Troubleshooting, pages 17 through 19
INSPECTING
BURNERS
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the
holes in the fitting at the burner entrance.
These holes may become blocked with dust
or lint. Periodically inspect these holes for
any blockage and clean if needed. Blocked
air holes will create soot.
MAIN BURNER
Periodically inspect all burner flame holes
with the heater running. All slotted burner
flame holes should be open with yellow
flame present. All round burner flame holes
should be open with a small blue flame
present. Some burner flame holes may be-
come blocked by debris or rust, with no flame
present. If so, turn off heater and let cool.
Either remove blockage or replace burner.
Blocked burner flame holes will create soot.
OPERATING
FIREPLACE
Continued
• In the AUTO mode, the thermostat
in the hand-held remote unit con-
trols the room temperature. To in-
crease the room temperature, press
the top arrow of the TEMP button.
To lower the room temperature,
press the bottom arrow of the
TEMP button. At higher settings
the heater will run longer.
IMPORTANT:
This remote control
has been specially engineered to
take an air temperature sample ev-
ery minute in the auto mode. It will
not respond immediately to the
temperature setting being turned
up or down.
IMPORTANT:
The hand-held re-
mote control unit must be near the
heater. Do not keep the hand-held
remote control unit too close to the
heater. The thermostat on the
hand-held remote control unit will
heat up too quickly and turn the
heater off.
3. To turn the burner off, press the
AUTO/ON/OFF button until OFF
lights. The pilot will remain lit.
IMPORTANT:
To turn the pilot off,
manually turn the control knob on the
heater to the OFF position.

OPTIONAL BLOWER
OPERATION
Locate the blower switch by opening lower
louver on fireplace. Blower switch is lo-
cated at lower left inside louver door.
The GA3700TA Series thermostat-con-
trolled blower has a variable speed con-
trol with an ON/OFF switch. The blower
will start when the thermostat senses a
sufficient increase in firebox temperature.
The GA3700 variable speed blower also
has an ON/OFF switch built into the vari-
able speed control.
Note for GA3700TA Series Only:
If
you are using GA3700TA series 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 modu-
lates to the pilot position, the blower will
continue to run. The blower will shut off
after the firebox temperature decreases.
Note:
It is safe to operate fireplace with
blower turned off. However, the blower helps
distribute heated air from the fireplace.
Follow installation instructions included
with the blower accessory.
WARNING: This fireplace has
a three-prong, grounded electri-
cal plug. This plug helps protect
you against electrical shock. Only
connect plug to a properly
grounded, three-prong recep-
tacle. Do not cut or remove the
grounding prong from this plug.
