INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED
OPERATION
NOTE: When used as a vented indoor appliance, appliance must be
installed only in a solid-fuel-burning fireplace with a working flue and
constructed of noncombustible material.
For Massachusetts Residents Only: Installation of this gas log set
as a vented indoor appliance in the Commonwealth of Massachusetts
requires the damper be permanently removed or welded in the fully
open position.
You must install the damper clamp accessory (to order, see Acces-
sories, Page 24). This will ensure vented operation (see Figure 8).
The damper clamp will keep damper open. Installation instructions
are included with clamp accessory.
See chart below for minimum permanent flue opening you must pro-
vide. Attach damper clamp so the minimum permanent flue opening
will be maintained at all times.
