If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to adjacent
structural framing, as shown on, Page 9, Figure 10. Bend
straps as necessary and make sure they are secure so
they will support the weight of the chimney. A chimney
support is 2¹⁄₂" (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.
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. Refer to firestop il-
lustration on Figure 19.
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 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 termina-
tion installed. Refer to installation instructions provided
with Vermont Castings Group chimney termination to find
correct size of roof hole.
There must be a 1¹⁄₂ (38 mm) air space between outermost
portion of chimney sections and any adjacent combustible
surfaces. (Combustible surfaces include burnable materi-
als such as: ceiling members, joists, flooring, combustible
FP263
insulation and roof structures.)
WARNINg: DO NOT PACK REQUIRED AIR SPACES
WITh INSULATION OR OThER MATERIALS.
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 ac-
cordingly.
Cover the opening of the installed chimney so debris can-
not get into the system.
