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 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. A 1 inch
(25mm) air space between the connector and the chimney
section must be maintained.
During installation 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.

CONNECTION TO A MASONRY
FIREPLACE
There are several kits available to connect the stove to
a masonry fireplace. Look for a listed kit. The kit is an
adapter which is installed at the location of the fireplace
damper. The existing damper may have to be removed to
allow installation of the kit.
The key points of this type of stove connection are: 1) that
the connector pipe must extend up the chimney above where
the fire clay liner starts, and 2) the areas of the kit installation
and penetration should fit tightly and be sealed with high
temperature furnace cement unless the kit’s instructions state
otherwise. (See Figure 14C). The tight fitting installation
aids the proper draw of the chimney.
Horizontal Flue Heat Shield, Accessory
Part HTSHLD-7006 is required for rear vent
installations.
