OPERATION

Note: The GHRC receiver and hand- held remote control kit must be purchased separately (see Accessories & Replacement Parts,page14).Followinstallation instruc- tions on pages 6 and 7 of this manual.

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 burner may light if hand-held remote ON button was on when selector switch was last turned off. You can now turn the burner 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.

PILOT ASSEMBLY ADJUSTMENT

The pilot assembly is factory preset for the proper flame height. Alterations to these settings may have occurred during shipping and handling, if this is the case, some minor readjustments may be necessary.

The pilot assembly is located behind the burner tube on the right hand side. The thermopile height should be at a distance of 3/8" to 1/2" from the pilot flame (see Figure 25).

BURNER FLAME ADJUSTMENT

The Air Shutter, located at the base of the Main Burner Tube has been factory preset to the proper air to gas ratio which results in a long, blue flame (see Figure 26).

If readjustment is necessary, you can restore proper flame setting by loosening the air shutter screw and rotating the air shutter until proper flame setting is achieved.

Tighten screw back (see Figure 17, page 7, for air shutter location).

Closing the Air Shutter reduces the air to gas mix resulting in a longer, yellow flame which could cause sooting.

OPERATING GUIDELINES AND MAINTENANCE INSTRUCTIONS

Do not use this appliance if any part has been under water. Immediately call a quali- fied service technician to inspect the appli- ance and to replace any part of the control system and any gas control which has been under water.

When lit for the first time, the appliance will emit a slight odor for about an hour or two. This is a normal occurrence which is due to the "curing" of logs and "burn-in" of inter- nal paints and lubricants used in the manu- facturing process.

In cleaning, take care not to alter the settings on the pilot assembly.

WARNING: Have a qualified agency periodically inspect the vent system at the start of each heating season so as to be free of any obstructions which may hinder normal operation. Never obstruct the flow of combustion and ventilation air; keep the front of the appliance clear of all ob- stacles and combustible materi- als such as gasoline or other flam- mable vapors or liquids. It is also imperative that the control com- partments, burners and circulat- ing air passageways of the appli- ance be kept clean.

CAUTION: Keep control com- partment, logs, burners, and area surrounding the logs clean by vacuuming or brushing at least twice a year. Temporary removal of the log set may ease the clean- ing of the burner and pilot assem- bly (see Installing Logs and Lava Rock, pages 8 and 9).

WARNING: The logs can be hot. Handle only when cool.
