For Vertical Terminations - To locate the vent and install

the vent sections:

• Locate and mark the vent centerpoint on the underside

of the roof, and drive a nail through the centerpoint.

• Make the outline of the roof hole around the centerpoint

nail.

• The size of the roof hole framing dimensions depend on the

pitch of the roof. There MUST BE a 1-inch (25.4mm) clear-

ance from the vertical vent pipe to combustible materials.

• Mark the roof hole accordingly.

• Cover the opening of the installed vent pipes.

• Cut and frame the roof hole.

• Use framing lumber the same size as the roof rafters

and install the frame securely. Flashing anchored to the

frame must withstand heavy winds.

• Continue to install concentric vent sections up through

the roof hole and up past the roof line until you reach the

appropriate distance above the roof.

WARNING: MAJOR U.S. BUILDING CODES

SPECIFY MINIMUM CHIMNEY AND/OR VENT

HEIGHT ABOVE THE ROOF TOP. THESE MINIMUM

To seal the roof hole, and to divert rain and snow from the

vent system:

• Attach a flashing to the roof using nails, and use a non-

hardening mastic around the edges of the flashing base

where it meets the roof.

• Attach a storm collar over the flashing joint to form a

water-tight seal. Place non-hardening mastic around the

joint, between the storm collar and the vertical pipe.

• Slide the termination cap over the end of the vent pipe

and snap into place.
