INSTALLING DAMPER CLAMP ACCESSORY
FOR VENTED OPERATION
Note:
When used as a vented heater, appliance must be installed
only in a solid-fuel burning fireplace with a working flue and
constructed of noncombustible material.
If your heater is a manually controlled model, you may use this
heater as a vented product. There are three reasons for operating
your heater in the vented mode:
1. The fireplace does not meet the clearance to combustibles re-
quirements for vent-free operation
2. State or local codes do not permit vent-free operation
3. You prefer vented operation

If reasons number 1 or 2 above apply to you, you must permanently
open chimney flue damper. You must install the damper clamp
accessory (to order, see Accessories, page 27). This will insure vented
operation (see Figure 10). 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 permanent flue
opening will be maintained at all times.
