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 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 win-
dow to vent smell. This will only
last a few hours.

Note:

Home owners generally prefer to oper-

ate 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.

1. STOP! Read the safety information,

page 20, column 2.

2. Make sure equipment shutoff valve is

fully open.

3. Turn control knob clockwise

to the

OFF position.

4. Wait five (5) minutes to clear out any gas.

Then smell for gas, including near the floor.
If you smell gas, STOP! Follow “B” in the
safety information, page 20, column 2. If
you don’t smell gas, go to the next step.

onds after lighting pilot. After 30 seconds,

tem to reset before lighting pilot again.
