INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burning fireplace with a working flue and
constructed of noncombustible material.
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 clear-
ance to combustibles requirements 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 apply to you, you
must permanently open chimney flue damper.
You must install the damper clamp accessory
(to order, see
Accessories
, page 31). 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 open-
ing will be maintained at all times.
