EIGHT INCH SOLID PACK CHIMNEY
WITH METAL SUPPORTS AS A
THIMBLE.
For the method of installation to a masonry chimney
shown in Figures 10 & 11, it will be necessary to pur-
chase a 8 inch inside diameter 12 inch long section of
prefabricated listed solid pack chimney to use as a
thimble. Purchase a wall spacer, trim collar and a
ware manufactured to fit the chimney section you
purchase.
The safety features of this system are: 2 inch air
space between the chimney section and combustible
wall, and the 1 inch air space around the chimney
connector as it passes through the chimney section
to the chimney.
The location of the opening through the wall to the
chimney must leave a minimum 18 inch vertical clear-
ance between the connector pipe and the ceiling to
prevent the ceiling from catching fire.
Cut out an opening in the wall large enough to
accommodate the outside dimension of the chimney
section plus the minimum air space specified by its
manufacturer. It may be necessary to cut the wall
studs and install a header and a sill frame to maintain
the wall support. The hole in the chimney must have
at least an 8 inch diameter fire clay liner or equivalent
secured with refractory mortar. If it is necessary to
cut a hole in the chimney liner, use extreme care to
keep it from shattering.
First, make the frame for the thimble, being sure it is
no smaller than 14 inches square, to maintain a 2
inch air space around the chimney section. Attach
the wall spacer to the chimney side of the frame.
Then insert the frame into the opening, toe nailing it
to the wall studs. Install the wall band in the framing
to secure the chimney section in place. Insert a sin-
gle section of chimney connector into the chimney
through the wall band, being sure it does not protrude
into the chimney beyond the edge of the chimney flue
lining. Apply high temperature furnace cement to the
end of the chimney section and install it over the con-
nector, through the wall spacer. Tighten the wall
band to hold the chimney section firmly in place and
against the chimney. Install the trim collar on the out-
side of the opening. Check to assure there is a 1
inch air space between the connector and the chim-
ney section. Also, during installation, always check to
assure that a 2 inch air space is being maintained to
the wood framing. Do not fill this space with insula-
tion. Insulation in this air space will cause a heat
buildup which may ignite the wood framing.
