Vent Requirements
! Always maintain the required 1” 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 it’s own separate vent system.
• This appliance is equipped only for
altitudes 0-2000 feet. However, our
in-house testing has shown that the
unit operated at altitudes to 8000 ft.
! 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 a 1/8" bead of high-temperature silicone or Mill-Pac® 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 1/4” rise every 12” of travel
+ Exterior Vent Diameter = 6-5/8” , Inner Vent Diameter = 4”
• Horizontal sections require non-combustible support every 36” (e.g.: use
plumbing tape)
