Installation – General Instructions
Prefabricated chimney with metal supports as a
thimble
For the method of installation to a masonry chimney
shown in Fig. 15 and 16, it will be necessary to purchase
a 12-inch long section of prefabricated listed chimney to
use as a thimble. Purchase a wall spacer, trim collar and
wall band that are manufactured to fit the chimney
section you purchase.
The safety features of this system are: the 2-inch air
space between the chimney section and combustible
wall, and the 1-inch 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 inch vertical
clearance between the connector pipe and the ceiling to
prevent the ceiling from catching fire.
For instructions on installation of the thimble, refer to
chimney manufacturer's instructions.
