In Canada, an attic insulation shield is required to
prevent attic insulation from contacting the chimney
section. If the attic insulation shield is used, the
firestop is not required in the attic installation. Framing
dimensions for the chimney hole should measure 14Z\x"
x 14Z\x" (368 x 368 mm) for SK8; 17Z\x" x 17Z\x" (445 x
445 mm) for 3-wall. An attic shield MUST be installed
on top of attic joists (above the floor level). (Fig. 20)
In the U.S., it is a good idea, although not al-
ways required, to install an attic insulation shield where
blown-in insulation is planned to be used in the attic.
Install the attic insulation shield with the flanges on its
base extending down into the framing hole. Nail each
corner of attic insulation shield to the framing members
of the ceiling hole using 8d nails. Attic shields are not
required at the roof.
Continue attaching pipe sections to complete system
to next level always being careful that the pipe is firmly
snapped locked in place before proceeding to next pipe
section.
If chimney supports are required, they are installed
the same as elbows. Nail chimney support straps to
adjacent structural framing, as shown on Page 7, Figure
7. Bend straps as necessary and make sure they are
secure so they will support the weight of the chimney. A
chimney support is 2Z\x" long when installed. Consider
this dimension when determining how many straight
chimney sections are needed.
Chimney supports are generally used in long
runs in a chase installation.
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. Refer to firestop
illustration on Figure 19.
Run pipe to roof line. Since chimney system must be
vented to the out-of-doors, you use an approved
termination.
If a chase is used, refer to the installation manual pro-
vided with the termination cap.
Use same procedure detailed in locating center point of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
If the attic insulation shield is used, the firestop is not
required in the attic installation.
