Vertical Cap Installations
Installation Instructions Cont.
Always maintain a 1” clearance around the vent pipe
(vertical) and on horizontal venting 2” clearance on the
top of the vent, when passing through ceilings, walls,
roofs, enclosures, attic rafters or any combustible sur-
faces.
DO NOT PACK AIR SPACES WITH INSULATION.
Refer to the vent chart on page 15 for maximum allow-
able vertical and horizontal allowable installations.
When planning your installation, determine if ceiling
joists, roof rafters or other framing will obstruct the vent
system. You may have to use 45° elbows to navigate
around any obstacles. When passing through a flat
ceiling, install a Box/Wall thimble. Cut a 10” square
hole and frame as shown in the diagram opposite.
Ensure all pipe sections are fully twist locked.
NOTE: ALWAYS CHECK YOUR LOCAL
CODES BEFORE INSTALLING VENTING.
CLEARANCES, ETC, MAY VARY FROM
STATE TO STATE(PROVINCE TO PROVINCE).

Use a suitable round or square support through
the roof. Ensure adequate heat shield protection
is provided. See diagram and chart for minimum
protection.
