Hussong Mfg. Co., Inc. • Kozy Heat Fireplaces
3.7 Vent Termination Framing
IMPORTANT: Vent cap location must be in compliance with 6.2
Minimum Termination Clearances on page 21.
WARNING: DO NOT RECESS THE VENT CAP INTO WALL OR
SIDING.
3.7.1 Vertical Terminations
CAUTION: Cold air transfer area. The surround fireplace chase
must comply with all clearances as outlined in this manual,
and be constructed in compliance with local building codes.
Outside walls should be insulated to prevent cold air from
entering room.
• Follow vent pipe manufacturer’s installation instructions for
vertical terminations.
• 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 non-combustible per ASTM E
136.
3.7.2 Horizontal Terminations
IMPORTANT: Horizontal vent sections require 1/4 in (6 mm)
rise for every 12 in (305 mm) of travel.
NOTE: Elbows listed with approved vent systems for this
appliance vary in vertical length. Please consult the vent
manufacturer’s instructions to determine the elbow dimension
used for installation. Adjust the wall pass-through rough
opening dimensions to maintain clearance requirements.
IMPORTANT: This fireplace horizontal vent installation requires
wall pass-through products to be fully lined with insulation
products listed as noncombustible per ASTM E 136. Failure to
line wall pass through products for all horizontal vent runs may
cause overheating and fire.
1. Measure from floor level of the fireplace to the center of
where the vent pipe will penetrate the wall.
2. Cut and frame an opening in the wall to allow the vent system
to run level through the wall pass-through. This wall pass-
through must be fully lined with insulation products listed as
noncombustible per ASTM E 136. A minimum clearance of
1 in (25 mm) on all sides of the horizontal vent pipe at the
insulated wall pass-through must be maintained.
3. Follow the vent pipe manufacturer’s installation instructions
for vent installation.
