IMPORTANT: Vent cap location must be in compliance with Section 6.2
Minimum Termination Clearances on page 23.
WARNING: DO NOT RECESS THE VENT CAP INTO WALL OR SIDING.
3.7.1 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.
3.7.2 Horizontal Terminations
IMPORTANT: Horizontal vent sections require 1/4” (6mm) rise for every
12” (305mm) 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 as necessary to maintain
clearance requirements.
IMPORTANT - METAL FAB VENT SYSTEM: When installing Metal Fab
vent pipe, adapter #4DDA must be used off the top of the appliance.
This will increase the minimum height for the center of the vent pipe
by 3-3/4” (95mm) when framing the wall pass through.
•
A minimum of 1” (25mm) clearance on the top, sides, and bottom
of the horizontal vent pipes must be maintained.
1. Measure from floor level of the fireplace to the center of where
the vent pipe will penetrate the wall.
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 as necessary to maintain clearance requirements.
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
vent installation.
