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. A 5"
x 8" to a 4" x 6-5/8" vent reducer for DuraVent and Selkirk vent
systems must be used. See appliance installation manual for
approved venting.
• A minimum of 1 in (25 mm) 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 in (25 mm) 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 in (25 mm) 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 ft of vertical drop, the total allowable length must be
reduced by 2 ft.
• 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.
2.1.1 Unit Specific Venting Requirements
• The Callaway-72 starts with a 5" x 8" 45° elbow off the back of
the appliance. Use a required 4" x 6-5/8" reducer off the elbow to
keep venting inside the minimum chamber requirements.
• The Callaway-40 starts with a 5" x 8" 45° elbow off the back of
the appliance. Use a required 4" x 6-5/8" reducer off the elbow to
keep venting inside the minimum chamber requirements.
