VENTING
The unit is a vented appliance and must be connected to a chimney/fl ue in accordance with the
code, using the chimney manufacturer's instructions.
This appliance must not be connected to a chimney fl ue servicing a
separate solid fuel burning appliance.
VENT DAMPER
This appliance may be installed with vent damper device Part No. MD8. Follow installation instruc-
tions for this part. This part is to be installed by a qualifi ed service person.
The vent damper is located in the mid section of pipe. Only this appliance may be served by the
vent damper device installed on this unit. The vent damper device should be inspected annually by
a qualifi ed installer.
The thermally controlled vent damper is an energy saving device designed for installation in vents
of listed gas-fi red appliances equipped with a draft hood. The damper saves energy by preventing
the escape of heated air through the venting system, when the appliance is not in use.
It has a round plate which will remain closed when the appliance is not in operation. Upon ignition
of the appliance, the hot fl ue gases reach the damper, causing the damper plate to thereby open
the vent passage within a short period of time.
Installation of vent dampers can increase the potential for condensation in oversized masonry
chimneys. This is due to poor thermal insulation of the chimney and reduced air movement when
the damper is closed. We recommend that masonry chimneys be lined with materials such as
Type B gas vent, aluminum or stainless steel to reduce the chance of condensation. Most building
codes, in fact, require the lining of chimneys when gas appliances are vented into masonry chim-
neys.
