Ceiling Opening:
1. Determine the exact position of the fireplace so that the vent pipe is
centered (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 1/2" opening in the floor, ceiling or 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 Firestop:
Where a vent pipe passes through a floor or ceiling, a ceiling firestop must be
used to retain insulation and maintain proper clearances.
From below, push the ceiling firestop through the opening and secure in place.
If the firestop is used to penetrate a floor, the outer shield may be trimmed in
length. If the firestop 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 first section of vent
pipe into the collar on top of the
fireplace. Secure in place with
screws and seal with approved
"High Temperature" self-adhesive
aluminium tape provided.
2. Continue adding vent pipe lengths
up and through the firestop(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 26 for precise lengths.
Seal the vent pipe as per “Figure 42:
TC36ST Sealing vent joints.” on page
27.
Roof Support Bracket:
1. Slip the roof support bracket
down over the vent pipe. Rotate
the 90° brackets to accommodate
roof pitch.
2. Attach the brackets to the roof
joists with nails or building
screws.
3. 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
combustibles.
