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.

OPERATING

OPTIONAL BLOWER

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.

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 (seeTo Turn Off Gas to Appliance, page 25)

•seeTroubleshooting, pages 28 through 30

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.
