For large fires, the maximum heating benefit from the fireplace will be
obtained with its glass doors fully open. The open doors will allow more
radiant heat to be emitted out of the front opening of the fireplace. When
the glass doors are open, close the fireplace’s mesh screens
to help keep burning embers from popping out of the firebox.
With a small fire, it is best to operate the fireplace with its glass doors
fully closed to prevent excessive room air from being drawn up the
chimney. To prevent room air from escaping up the chimney overnight,
close the fireplace glass doors before retiring in the evenings.
With the provided AK6A combustion air kit installed on the
fireplace, outside combustion air may enter the firebox through
a dampered opening located on the left side of the fireplace.
This feature reduces the room air used for combustion and
prevents excessive heat loss from the room. When the fire-
place is in use, this damper should be open . When the
fireplace is not in use, the damper may be closed to prevent
cold air from entering the firebox. The outside combustion
air control lever is located inside the fireplace firebox just
above the brick panel on the left side of the firebox as shown
by Figure 5.
NOTE: Outside combustion air damper is open when
its control lever is up. The damper is closed
when its control lever is down.
The fireplace must be supplied with outside combustion air
when the fireplace is installed in a manufactured home. See the
Outside Combustible Air section of this manual for additional
information about outside combustion air.
This fireplace is equipped with a factory-installed fan assem-
bly to help circulate heat produced by the fireplace. The fanʼs
ON/OFF rocker switch is installed in the left side of the lower
louver panel on the front of the fireplace. Use the ON/OFF
rocker switch to turn the fan on and off as desired for heat
circulation. See the Wiring for Fan Assembly, page 27 of this
manual for additional information about fan assembly.

The fireplace should be operated only with
its glass doors fully open or fully closed. If
glass doors are left partially open, gas and
flame may be drawn out of fireplace opening.
This creates risks of both fire and smoke. See
Figures 3 and 4.
