Figure 3.5, Vent Termination Locations
3.6 Vent Termination Rough Framing
IMPORTANT: Vent cap location must be in compliance with Section 6.2
Minimum Termination Clearances on page 26
WARNING: DO NOT RECESS THE VENT CAP INTO WALL OR. SIDING.
3.6.1 Vertical Terminations
Follow vent pipe manufacturer’s installation instructions for vertical
terminations.
•
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 non-combustible per ASTM E 136.
3.6.2 Horizontal Terminations
IMPORTANT: Horizontal vent sections require 1/4” (6mm) rise for every
12” (305mm) of travel for natural draft applications.
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 - METAL FAB VENT SYSTEM : When installing Metal Fab
vent pipe, an adapter must be used. This will increase the minimum
height for the center of the vent pipe by 3-1/4” (83mm) when framing
the wall pass through.
•
A minimum of 3” (76mm) clearance from the top surface on the
horizontal pipe must be maintained.
•
A minimum of 1” (25mm) on the sides and bottom surfaces on
the horizontal pipe must be maintained.
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.
3. Follow the vent pipe manufacturer’s installation instructions for
draft vent installation.
3.6.2.1 Wall Pass Through Information and Framing
Kozy Heat’s #800-WPT series, or wall thimble products that comply

unfaced insulation products listed as noncombustible per ASTM E
136.
