Size of the opening will have
to increase with the pitch of
the roof to ensure a 1¾" inch
air space clearance between
vent pipe and combustibles.

Ceiling Opening:
1. Determine the exact position of the replace so that the vent pipe is cen-
tered (if possible) between two building framing members. Lay out the vent
system path, minimizing the number of elbows and length of vent. Consult
your local building codes prior to proceeding.
2. Cut and frame a 14 ½" opening in the oor, ceiling or roof where the vent
system will pass. Size of the opening in the roof may need to be increased
B
as the pitch of the roof increases. Avoid cutting rafters.
Ceiling Firestop:
Where a vent pipe passes through a oor or ceiling, a ceiling restop (Figure 52)
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 re-
place. Secure in place with screws
and seal with approved "High
Temperature" self-adhesive alu-
minium 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 12" above the
roof. Vent pipe may need to extend
further depending on the roof pitch.
See "Roof Pitch Table" on page
28 for precise lengths. Seal
the vent pipe as per "Vent Pipe
Sealant" on page 29.
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.
