SOLID PACK CHIMNEY WITH METAL SUPPORTS AS A THIMBLE

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" (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" (51mm) air space between the chimney section and combustible wall; and, 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 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" (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.

NOTE: ALL HORIZONTAL INSTALLATIONS REQUIRE ACCESSORY HORIZONTAL FLUE SHIELD, PART HTSHLD-7006, TO COMPLY WITH REQUIRED CLEARANCES.

NOTE: OPTIONAL FIRE SCREEN, PART SCR-7006, CAN ONLY BE USED IN FULL VERTICAL INSTALLATIONS.
