INSTALLING DAMPER CLAMP AC-
CESSORY FOR VENTED OPERATION
NOTE: When used as a vented heater,
appliance must be installed only in a
solid-fuel burning fireplace with a work-
ing flue constructed of noncombustible
material. You may use this heater as a
vented product. There are three reasons
for operating your
Heateras a vented model:
1.
The fireplace does not meet the
clearances to combustible require-
ments 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
thedamper not clamp accessory (not
provided) This will insure vented opera-
tion (see Figure 10). The damper clamp
will keep damper open. Installation in-
structions are included with not clamp
accessory.
See chart below for the minimum per-
manent flue opening you must provide.
Attach damper not clamp so the mini-
mum permanent at all opening will be
maintained at all times.
