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 

Accessories, 

Page 23

).

 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 provide. Attach damper clamp so the minimum perma-

nent flue opening will be maintained at all times.
