Metal Supports As A Thimble - Quadra-Fire Isle Royale 823-0170 Manual

SOLID PACK CHIMNEY WITH METAL SUPPORTS AS A THIMBLE (CONT'D)
First, make the frame for the thimble, ensuring it
is no smaller than 14 inches (356mm) square to
maintain a 2 inch (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 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 outside of the opening.
Check to ensure there is a 1 inch (25mm) air space
between the connector and the chimney section.
During installation ensure that a 2 inch (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.
