SOLID PACK CHIMNEY WITH METAL SUPPORTS AS A THIMBLE (Cont’d)
First, make the frame for the thimble, ensur- ing 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 open- ing, 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 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.
