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 its own separate vent system.
 In addition to the requirements listed here, follow the requirements provided with the vent.
 The fireplace must use the Travis Thimble (sku 250-02318) whenever the vent penetrates a wall.
Other penetrations only require a 1" (25mm) clearance and may use a standard firestop (make sure
the required 1" (25mm) clearance is met).
Vent Clearances
 The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill
air spaces with insulation.
Sides 1" (25mm)
Above 4" (102mm)
Below 1" (25mm)
Altitude Considerations

This heater has been tested at altitudes ranging from sea level to 6,000 feet (1800 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.
