For Vertical Terminations - To locate the vent and install the vent sections:

 

Locate and mark the vent centerpoint on the under-

 

 

side 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 (25.4 mm) clearance 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 (for inside vent installations) or

 

 

up past the roof line until you reach the appropriate

 

 

distance above the roof (for outside terminations).

 

 

 

 

 

WARNING

 

 

MAJOR U.S. BUILDING CODES

 

 

SPECIFY MINIMUM CHIMNEYAND/OR

 

 

VENT HEIGHT ABOVE THE ROOF TOP.

 

 

THESE MINIMUM HEIGHTS ARE

 

 

NECESSARY IN THE INTEREST OF

 

 

SAFETY. SEE THE FOLLOWING

 

 

DIAGRAM FOR MINIMUM HEIGHTS,

 

 

PROVIDED THE TERMINATION CAP IS

 

 

AT LEAST TWO (2) FEET FROM A

 

 

VERTICAL WALLAND 2-FEET BELOWA

 

 

HORIZONTAL OVERHANG.

NOTE

This also pertains to vertical vent systems installed

 

on the outside of the building.
