OPTIONAL REMOTE

OPERATION

Note: All remote control accessories must be purchased separately (see Accessories, page 23). Follow instructions included with the remote control.

Thermostat Control Operation

(Optional GHRCT Only) The thermo- stat control setting on the remote control unit can be set to any comfort level be- tween HI and LO. The burners will turn on and off automatically to maintain the comfort level you select. The ideal com- fort setting will vary by household de- pending upon the amount of space to be heated, the output of the central heating system, etc.

For wall thermostat operation, follow in- struction supplied with thermostat acces- sory GWMT1. For wall switch operation follow instructions supplied with GWMS2.

NOTICE: You must light the pilot before using the hand-held re- mote control unit. See Lighting Instructions on page 14.

1.After lighting, let pilot flame burn for about one minute. Turn control knob to ON position. Adjust flame adjust- ment knob anywhere between HI and LO. Slide the selector switch to the REMOTE position. Note: The burn- ers 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 control 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 buttons on the hand-held remote control unit for up to 3 sec- onds to assure proper operation.

GHRC Operation:

2a. Press the ON/OFF button to turn the burners on and off. When turning burners off, the pilot will remain lit.

GHRCT Operation:

2b. Select the MAN (manual) or AUTO button on the hand-held remote con- trol unit (see Figure 24, page 16).

•In manual mode, turn burners on or off by pressing the ON or OFF buttons on the hand-held remote control unit.

•In auto mode, the room tempera- ture is controlled by the thermo- stat in the hand-held remote con- trol unit. To increase the room tem- perature, press the top arrow of the TEMP button. To lower room the temperature, press the bottom ar- row 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 5.5 minutes 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.
