NOTE:
If the attic insulation shield is used, the
firestop is not required in the attic installation.
Continue Installing
Pipe to Complete Run
Continue attaching pipe sections to complete system to
next level always being careful that the pipe is firmly snap-
locked in place before proceeding to next pipe section.
Chimney Supports
If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to adjacent
structural framing, as shown on Page 8, Figure 8. Bend
straps as necessary and make sure they are secure so
they will support the weight of the chimney. A chimney
support is 2
Z\x
" (64 mm) long when installed. Consider this
dimension when determining how many straight chimney
sections are needed.
NOTE:
Chimney supports are generally used in long runs
in a chase installation.
Additional Ceilings
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. See firestop illustration
in Page 11, Figure 15.
Penetrating the Roof
Run pipe to roofline. Since chimney system must be vented
to the out-of-doors, you
must
use an approved Vermont
Castings Group termination.
If a chase is used, refer to the installation manual provided
with the termination cap.
Locate Chimney Centerpoint On Roof
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.
Cut and Frame Roof Hole
Size of roof hole varies with the type of chimney termina-
tion installed. Refer to installation instructions provided

Canadian Requirements
for Insulation Shield
In Canada, an attic insulation shield is required to pre-
vent attic insulation from contacting the chimney section.
NOTE:
If the attic insulation shield is used, the firestop is
not required in the attic installation. Framing dimensions
for the chimney hole should measure 17
Z\x
” x 17
Z\x
” (445 x
445 mm). An attic shield MUST be installed on top of attic
joists (above the floor level). (Fig. 16)
NOTE:
In the U.S., it is a good idea, although not always
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.
