Installation (for qualified installers only)

Vent Requirements

•
The gas appliance and vent system must be vented directly to the outside of the building, and
never be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each
direct vent gas appliance must use it's own separate vent system.
•
Make sure the exhaust pipe on the heater connects to the exhaust portion of the cap. The
illustrations below show how the flex liners should be attached.
•
The exhaust vent must reline the entire length of the chimney and terminate above the
chimney top
•
Be careful not to crimp or rupture the liner when bending it into chimney offsets
•
When installed, the vent must meet all of the vent manufacturer's requirements
•
Make sure to order the following:
3" UL 441 Gas Liner for Exhaust and Air Inlet
6-5/8" to 3" & 3" Co-Linear Adapter & Flashing (Simpson Duravent Part # 923GK).
Vertical Termination Cap (Dura-Vent pt # 991)

Altitude Considerations

•
This heater has been tested at altitudes ranging from sea level to 8,000 feet (2,400 M). In this testing we
have found that the heater, with its standard orifice, burns correctly with just an air shutter adjustment.
•
Failure to adjust the air shutter properly may lead to improper combustion which can create a safety hazard.
Consult your dealer or installer if you suspect an improperly adjusted air shutter.
