INSTRUCTIONS

WARNING:

•If fireplace has glass doors, never operate this heater with glass doors closed. If you operate heater with doors closed, heat buildup inside fire- place will cause glass to burst. Make sure there are no obstructions across openings of fireplace.

•You must operate this heater with a fireplace screen in place. Make sure fireplace screen is closed before running heater.

NOTICE: During initial operation of new heater, burning logs will give off a paper-burning smell. Orange flame will also be present. Open damper or window to vent smell. This will only last a few hours.

Note: If pilot does not stay lit, contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure, page 17.

WARNING: Do not operate heater between PILOT and HIGH positions.

Note: Home owners generally prefer to operate their heater with the chimney damper closed. This will put all the heat into the room. However, there may be times you will desire the full flames of the HI heat setting but will find the heat output excessive. You can open the chimney damper (if you have one) fully or partially to release some of the heat.

VARIABLE CONTROL

OPERATION

The variable control valve can be set to any heat setting and flame height desired, by simply turning the control knob until that setting is attained. Even the lowest setting provides realis- tic, dancing yellow flames. Selecting higher settings produces greater heat output. This results in increased heating comfort.

CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.
