ROOF TERMINATION VENTING
Ceiling opening:
1) Determine the exact position of the  replace so that the
vent pipe is centered (if possible) between two building
framing members. Lay out the vent system path, minimiz-
ing the number of elbows and length of vent. Consult your
local building codes prior to proceeding.
2) Cut and frame a 14 1/2" opening in the  oor, ceiling and
roof where the vent system will pass. Size of the opening
in the roof may need to be increased as the pitch of the
roof increases. Avoid cutting rafters.
Ceiling  restop:
Where a vent pipe passes through a  oor or ceiling, a ceiling
 restop must be used to retain insulation and maintain proper
clearances.
From below, push the ceiling  restop through the opening
and secure in place. If the  restop is used to penetrate a
 oor, the outer shield may be trimmed in length. If the  restop
penetrates into an attic, leave the shield full length to keep
insulation away from the vent pipe. Additionally, after the vent
pipe is in place, install a storm collar on top of the shield. This
will prevent loose insulation from falling into the area between
the vent pipe and the shield.
Vent pipe:
1) Install the  rst section of vent pipe into the collar on top of the
 replace. Secure in place with screws and seal with approved
"High Temp." self-adhesive aluminum tape provided.
2) Continue adding vent pipe lengths up and through the
 restop(s) and through the roof. The vent pipe must extend
at least 24" above the roof.
Seal the vent pipe as per "Vent Pipe Sealant" section.
Roof support bracket:
Slip the roof support bracket down over the vent pipe. Rotate
the 90° brackets to accommodate roof pitch. Attach the brackets
to the roof joists with nails or building screws. Tighten the band
around the vent pipe and secure in place with screws.

Size of the opening will have to increase with
the pitch of the roof to ensure a 1 3/4 inch air
space clearance between vent pipe and com-
bustibles.
