pilot flame is not properly heating the thermocouple. When the
thermocouple cools, the heater will shut down.

Safety Features
When away from home for an extended period of time or as a
child safety feature to prevent accidental ignition of the fire-
place, the receiver ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
1. If the average room temperature exceeds 82 degrees Fahr-
enheit (28 degrees Centigrade), the hand-held remote con-
trol will perform a safety override and shut the fireplace
off. This feature is not available in the MANU mode.
2. The receiver continuously receives signals from the hand-
held remote to control the room temperature. If the hand-
held remote is misplaced, obstructed, or for any reason
cannot transmit to the receiver, the receiver will shut off
the fireplace after 8 minutes.
Key Pad Lock Feature
This feature allows the user to lock/unlock the keypad on the
hand-held remote in the MANU or AUTO mode to prevent
inadvertent operation (i.e. children operating the hand-held re-
mote control, etc.). The keypad is locked in either on or off. Press
the POWER and LOCK buttons together to turn the unit on or off.
Locate the blower switch by opening lower louver on fireplace.
Blower switch is located at lower left inside louver door.
The GA3700TA thermostat-controlled blower has a variable
speed control 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 variable speed control.
Note for GA3700TA Only:
If you are using GA3700TA 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.
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 electrical plug. This plug helps protect you
against electrical shock. Only connect plug to a
properly grounded, three-prong receptacle. Do not
cut or remove the grounding prong from this plug.
