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" (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 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 ensure there is a 1" (25mm) air space between the connector and the chimney section.

During installation ensure 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.

NOTE: Optional Fire Screen, Part SCR-7006, can only be used in FULL Vertical installations

CONNECTION TO A MASONRY FIREPLACE

Figure 14C

Support Plate & Clamp

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 that the connector pipe must extend up the chimney above where the fire clay liner starts, and the areas of the kit installation and penetra- tion 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.
