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
constructed of noncombustible material. You may use this heater
as a vented product. There are three reasons for operating your
heater as a vented model:
1. The fireplace does not meet the clearance requirements for
vent-free operation.
. State or local codes do not permit vent-free operation.
3. You prefer vented operation.
If reasons number or above apply to you, you must perma-
nently open chimney flue damper. You must install the damper
clamp accessory (not provided). This will insure vented operation
(see Figure 0). The damper clamp will keep damper open. Instal-
lation instructions are included with clamp accessory.
See chart below for the minimum permanent flue opening you
must provide. Attach damper clamp so the minimum permanent
opening will be maintained at all times.
