CLAMP ACCESSORY FOR
VENTED OPERATION
Note:
When used as a vented heater, appli-
ance 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 operat-
ing 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 above apply to you,
you must permanently open chimney flue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
24). 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.
