2.0 VENTING

2.1 Venting Requirements

For information on standard procedures for venting the appliance,
refer to the venting section of your specific appliance installation
manual.
• The #KPV is for use 4" x 6-5/8" coaxial rigid direct vent pipe.
Depending on your appliance, the vent size must be reduced
to 4" x 6-5/8". See appliance installation manual for approved
venting.
• A minimum of 1" (25mm) clearance on all sides of the vertical
vent pipe must be maintained. Attic insulation shields may
be insulated using unfaced insulation products listed as
noncombustible per ASTM E 136.
• A minimum of 1" (25mm) clearance on all sides of the horizontal
vent pipe at the wall pass-through must be maintained. Wall
thimble products that comply with the required 1" (25mm)
clearance to combustibles must be installed for all horizontal
vent runs that pass through interior or exterior walls. These wall
thimble products may be insulated using unfaced insulation
products listed as noncombustible per ASTM E 136.
• For every 1' of vertical drop, the total allowable length must be
reduced by 2' .
• If a pipe configuration includes a vertical component that goes
downward, a vertical component going back upward is not
allowed.
• Before installation, apply a bead of the provided sealant around
the inner exhaust pipe connection on the fireplace and the
power vent assembly. See Figures 2.1 and 2.2. Each individual
pipe manufacturer may require or recommend additional sealant
in between each vent pipe connection. After completing the
vent pipe installation, ensure all of the vent pipe connections are
sealed properly before fireplace operation.
