1. The fireplace does not meet the clearance
to combustibles requirements for vent-
free operation.
2. State or local codes do not permit vent-

must permanently open chimney flue damper.
You must install the damper clamp accessory
(to order, see

The damper clamp will keep damper open.
Installation instructions are included with
clamp accessory.
