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.
Vent Clearances
•
The vent must maintain the required clearance to combustible materials to prevent a fire. Do
not fill air spaces with insulation.

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.
Approved Vent
•
Use 8" diameter Model GS Direct Vent manufactured by Simpson Dura-Vent only. Follow the
installation instructions included with the vent. For the nearest Simpson Dura-Vent supplier,
call (800) 835-4429.
•
Always use the high-wind termination (if applicable).
