Vent Requirements
! Always maintain the required 1Ó (25 mm) clearance (air space) to combustible materials to prevent a fire
hazard. 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 itÕs 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.
¥ When the vent passes through a wall,
a wall thimble is required. When the
vent passes through a ceiling, a
support box or firestop is required.
When the vent passes through the
roof, a roof flashing and storm collar
are required. Follow the instructions
provided with the vent (from
Duravent¨) for installing these items.
Use a firestop spacer whenever
passing through a ceiling

¥ Apply high-temperature silicone to the inner and outer pipe before
assembling the sections (on the male, upper section). This seals the
inner pipe from the outer pipe. Slide the sections together and turn 1/4
turn until the sections lock in place. Install three metal screws through
each joint to lock the outer section in place (see the instructions included
with the vent for further details).
NOTE: You may screw the first section of vent to the appliance.
¥ Horizontal sections require a 1/4Ó rise every 12Ó of travel
Apply a 1/8" (3 mm)
bead of high-
temperature silicone
to the inner and
outer pipe. The
silicone must seal
the inner pipe from
the outer pipe.
