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 fur-
ther depending on the roof pitch. For precise
lengths, See “Roof Pitch Table” on page 25.
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.
Ceiling Opening:
1. Determine the exact position of the fireplace 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 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 (TCVT.
THIMA) 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.
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.
