WARNING! DO NOT operate fireplace before reading and
understanding operating instructions. Failure to operate
fireplace according to operating instructions could cause
fire or injury.

1. Flue Damper

The flue damper must be in the fully open position
(handle all the way to the top and locked in the notch)
during operation of the fireplace. See Figure 3.2.
Before lighting the fireplace, verify the fully open posi-
tion by looking up from the inside of the fireplace.
2. Outside Air
The outside air supplies cooling air and combustion air
for the fireplace. The OA damper is also controlled by
the damper control handle. When the handle is in the
upward position, the OA damper is open. See Figure
3.2.
When the control handle is down and in the locked po-
sition, the OA damper and damper are in the closed
position.
Close the damper to prevent cold drafts when the fire-
place is not being used.
