LIGHTING
INSTRUCTIONS
WARNING:
• If fireplace has glass doors,
never operate this heater with
glass doors closed. If you oper-
ate heater with doors closed,
heat buildup inside fireplace 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, 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: 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 chim-
ney damper (if you have one) fully or
partially to release some of the heat.
