First, make the frame for the thimble,
ensuring it is no smaller than 14" (356mm)
square, to maintain a 2" (51mm) 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 single section of chimney con-
nector 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 connector, 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 outside of the
opening. Check to make sure there is a 1"
(25mm) air space between the connector
and the chimney section.
During installation be certain that a 2"
(51mm) air space to the wood framing
is maintained. Do not fill this space with
insulation. Insulation in this air space will
cause a heat buildup which may ignite the
wood framing.
