ACCESSORY FOR VENTED
OPERATION
NOTE: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burning fi replace with a working fl ue and con-
structed of noncombustible material.
For Massachusetts Residents Only:
Instal-
lation of this gas log set as a vented appliance
in the Commonwealth of Massachusetts re-
quires the damper be permanently removed
or welded in the fully open position.
If your heater is a non-thermostatically-
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
fi replace does not meet the clearance
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 fl ue
damper. You must install the damper clamp
accessory
(to order, see Accessories, Page
29).
This will ensure 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 fl ue
opening you must provide. Attach damper
clamp so the minimum permanent fl ue open-
ing will be maintained at all times.
