Installation

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 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.

Clearances

Minimum 1" clearance to all combustibles (measured from the outside of the pipe) e x c e p t for the following:
When using 6-5/8" vent, a
horizontal termination, and
an elbow directly off the
top of the fireplace, a 2"
clearance is required
above the horizontal
sections (1" to the side
and below).
Use of 8" Diameter Pipe
• Most venting configurations use 6-5/8" diameter vent. To achieve longer horizontal runs (over 12')
with a horizontal termination, 8" dia. Simpson Duravent type GS Direct Vent may be used. See the
section "Horizontal Terminations using 8" Diameter Vent" for details. Part Numbers are listed below.
