LIGHTING 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. Also if fireplace
opening has vents at the bottom, you must open
the vents before operating heater.
• 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, burn-
ing 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:
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.
WARNING: Damper handle will be hot if heater
has been running.
