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 Installing Pipe to Complete Run
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.
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, Fig.
9. Bend straps as necessary and make sure they are
secure so they will support the weight of the chimney.
A chimney support is 2
¹⁄₂
" (64mm) long when in-
stalled. 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. Refer to firestop
illustration on Page 12, Figure 18.
Penetrating the Roof
Run pipe to roofline. Since the chimney system must
be vented to the out-of-doors, you must use an
approved 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 centerpoint 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
termination installed. Refer to installation instructions
provided with the chimney termination to find correct
size of roof hole.
There must be a 1
¹⁄₂
(38mm) air space between
outermost portion of chimney sections and any adja-
cent combustible surfaces. (Combustible surfaces
include burnable materials such as: ceiling members,
joists, flooring, combustible insulation and roof struc-
tures.)
WARNING: DO NOT PACK REQUIRED AIR
SPACES WITH INSULATION OR OTHER MATERI-
ALS.
Mark an outline of the roof hole around the center of
the point nail. NOTE: Hole dimensions given in the
chimney top installation instructions are horizontal
dimensions; therefore, the hole size must be marked
on the roof accordingly.
Cover the opening of the installed chimney so debris
cannot get into the system.
Cut and frame the hole. It is good practice to use
framing lumber that is the same size as the rafters.
Install the frame securely because the chimney top
and flashing anchored to the frame must be able to
withstand heavy winds.
Install Remainder of Chimney Sections
Since you have already preplanned the height of your
termination according to the
Ten Foot Rule, continue to
install pipe to the predetermined height.
Check the chimney top installation instructions for
details on how high above the roof top the chimney
sections (all pipes) should extend.
