SOLID PACk CHIMNEY WITH METAL SUPPORTS AS A THIMBLE
For the method of installation to a masonry chimney shown in Figures 13A & 13B on page 13, it will be necessary to pur-
chase a 12” (305mm) long 8" (203mm) inside diameter, section of prefabricated Listed solid pack chimney to use as a thimble.
Purchase a wall spacer, trim collar, and a wall band manufactured to fit the chimney section you purchase.
The safety features of this system are two fold:
1. A 2" (51 mm) air space between the chimney section and combustible wall
2. The 1" (25mm) air space around the chimney connector as it passes through the chimney section to the chimney.
The location of the opening through the wall to the chimney must leave a minimum 18" (457mm) vertical clearance
between the connector pipe and the ceiling (or minimum recommended from pipe manufacturer) to prevent the
ceiling from catching fire.
Measure for the center-line as shown in Figure 11A below. Cut an opening in the wall large enough to accommodate the
outside dimension of the chimney section plus the minimum air space specified by its manufacturer. It may be necessary
to cut the wall studs and install a header and a sill frame to maintain the wall support. The hole in the chimney must have
at least an 8" (203mm) diameter fire clay liner or equivalent, secured with refractory mortar. If it is necessary to cut a hole
in the chimney liner, use extreme care to keep it from shattering.
WARNING! ALWAYS FOLLOW CHIMNEY CONNECTOR MANUFACTURER’S INSTRUCTIONS FOR PROPER INSTALLATION.
CHIMNEY CONNECTOR IS TO BE USED ONLY WITHIN THE ROOM, BETWEEN THE STOVE AND CEILING OR WALL, NEVER
PASSING THROUGH A COMBUSTIBLE CEILING OR WALL. THE CONNECTOR SHALL NOT PASS THROUGH AN ATTIC OR
ROOF SPACE, CLOSET OR SIMILAR CONCEALED SPACE, OR A FLOOR, OR CEILING. MAINTAIN MINIMUM CLEARANCES
TO COMBUSTIBLES AS REFERENCED ON PAGE 7.
Add center-line measurement to
depth measurement of your floor pro-
tector. Mark this combined measure-
ment at correct wall location for your
installation, maintaining minimum
clearance to combustibles.
