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

secure vent sections together if desired.
• High temperature sealant is recommended at the appliance starter section connection
(use high-temperature silicone or Mill-Pac®).
• If disassembly is required, at time of re-assembly check to see if the vent creates a tight
fit. If it does not, apply high temperature sealant to the joints of the affected sections.
• Horizontal sections require a 1/4" rise every 12" of travel
• Horizontal sections require non-combustible support every three feet (e.g.: plumbing
