Vent Requirements
! 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.
! Make sure the exhaust pipe (the inner pipe) on the heater connects to the exhaust portion of the cap
(the inner pipe). The illustrations below show how the flex liners should be attached.
! If the heater is
installed at an
altitude over 3,000
(1,000 M) feet the
flame quality will
need to be carefully
evaluated. See
Addendum #1,
"Altitude
Considerations", on
page 49.
? When using flexible
gas vent, do not
crimp or rupture the
liner when bending it
into chimney offsets
• When installed, the
vent must meet all of
the vent
manufacturer's
requirements

options for vent
