Figure 8.5 Installing the Ceiling Firestop
• Support the pipe during construction and check to be
sure inadvertent loading has not dislodged the chimney
section from the fireplace or at any chimney joint.
• Attach a straight chimney section or an offset to the top
of the fireplace.
• Place inner flue to the inside of the chimney section below
it. Place the outer casing outside the outer casing of the
chimney section below it. Refer to Figure 8.4.
NOTICE: Chimney sections cannot be disassembled
once locked together. Plan ahead!
• Lock chimney sections and/or offsets/returns together by
pushing downward until the top section meets the stop
bead on the lower section.
• Pull on the top section to make sure it is fully engaged
and will not separate.
• You may use #6 or #8 sheet metal screws no longer than
1/2 in. (13 mm) to fasten chimney sections together. Do
NOT penetrate inner flue.
WARNING! Risk of Fire! You MUST use screws (pro-
vided) to fasten offset/returns to chimney sections to
keep the chimney parts from twisting. Failure to do so
could cause fire.
• Fasten offset/returns to chimney sections. Insert the
screws (provided) through the predrilled holes. Do NOT
penetrate inner flue.
• Secure chimney returns with hanger straps provided;
fasten to studs or joists.
• Vertical straight runs of chimney must be supported every
35 ft (10.7 m).
C. Assemble Chimney Sections
WARNING! Risk of Fire! DO NOT install substitute or
damaged chimney components.
• Use only those components described in this manual.
Substitute or damaged chimney components could impair
safe operation and cause overheating and fire.
D. Install Chimney Air Kit
• Required in Canada.
• Follow instructions provided with this accessory.
• Install a ceiling firestop whenever chimney penetrates
ceiling/floor.
• Mark and cut an opening in ceiling as shown in
Figure 8.5.
• Frame the opening with the same size lumber used in
the ceiling joists.
• Nail the ceiling firestop to the bottom of the ceiling joists
when there is a room above.
• Use an attic insulation shield if the ceiling is insulated.
The ceiling firestop may then be attached above or below
the joists.
E. Install Ceiling Firestops
CAUTION! Risk of Fire! Ceiling firestops must be used
whenever the chimney penetrates a ceiling/floor.
• Chase construction requires ceiling firestops at each
floor or every 10 ft (3.05 m) of clear space.
• The ceiling firestop slows spread of fire and reduces cold
air infiltration.
WARNING! Risk of Fire! DO NOT seal area between
firestop opening and chimney pipe except where they
enter the attic or leave the warm air envelope of the
home (use 600° F sealant).
