Heat & Glo LifeStyle EVEREST manual For Vertical Terminations To locate the vent

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.

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.

• 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).

VENT HEIGHT ABOVE THE ROOF TOP. THESE MIN- IMUM HEIGHTS ARE NECESSARY IN THE INTER- EST OF SAFETY. SEE THE FOLLOWING DIAGRAM FOR MINIMUM HEIGHTS, PROVIDED THE TERMI- NATION CAP IS AT LEAST TWENTY INCHES FROM
