SOLID PACK CHIMNEY WITH METAL SUPPORTS AS A THIMBLE
Add the 19-5/16" (491mm), center-line measurement to
the depth measurement of your floor protector. Mark
this combined measurement at the correct wall location
for your installation, maintaining minimum clearance
to combustibles, and mark the wall for a 10 inch x 10
inch (254mm x 254mm) square hole. The center of the
square hole should line up with the centerline of the rear
vent flue pipe, as shown above.

For the method of installation to a masonry chimney shown in Figures 14A & 14B on page 14, it will be necessary to purchase
a 12 inch (305mm) long, [8 inch (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 purchased.
The safety features of this system are twofold: 1) A 2 inch (51mm) air space between the chimney section and combustible
wall; and, 2) The 1 inch (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 inches (457mm) vertical clearance between
the connector pipe and the ceiling to prevent the ceiling from catching fire.
Measure as shown in Figure 13A. 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 inch (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 PAGES 6 & 7.
