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

OPERATION

WARNING: This fireplace has

a three-prong, grounded electrical

plug. This plug helps protect you

against electrical shock. Only con-

nect plug to a properly grounded,

three-prong receptacle. Do not cut

or remove the grounding prong

from this plug.

Locate the blower switch by opening lower

louver on fireplace. Blower switch is located at

lower left inside louver door.

The GA3650TB thermostat-controlled blower

has a variable speed control with an ON/OFF

switch. The blower will start when the ther-

mostat senses a sufficient increase in firebox

temperature. The GA3750A variable speed

blower also has an ON/OFF switch built into

the variable speed control.
Note for GA3650TB Only:

If you are using

GA3650TB 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.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat-

terns 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 properly 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 Appli-

ance, page 18)

• see Troubleshooting, page 23
Note:

The pilot flame on natural gas units will

have a slight curve, but flame should be blue and

have no yellow or orange color.

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 become blocked by debris or rust, with no

flame present. If so, turn off heater and let cool.

Remove blockage. Blocked burner flame holes

may create soot.

FRONT BURNER FLAME PATTERN

WARNING: If front burner

flame pattern shows yellow tip-

ping, your fireplace could pro-

duce increased levels of carbon

monoxide. Follow instructions

below. Yellow flame on rear

burner is normal.
