LIGHTING
INSTRUCTIONS
WARNING
• If fireplace has glass doors,
never operate this heater with
glass doors closed. If you op-
erate heater with doors closed,
heat buildup inside fireplace
will cause glass to burst. Make
sure there are no obstructions
across opening 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 pres-
ent. 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. How-
ever, there may be times you will desire the
full flames of the highest 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.
WARNING: Burners will
come on automatically within
one minute when the control
valve is in the ON position after
the pilot is lit.
