Vent Requirements

! The vent must maintain the required clearance to combustible materials to prevent a fire (see
"Clearances" below). Do not fill air spaces with insulation.
! 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.

Altitude Considerations

This fireplace has been tested at altitudes ranging from sea level to 8,000 feet (2,400 M). In this testing we have
found that the fireplace, 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.
