CHIMNEY CHASE REQUIREMENTS
Framing should be constructed of 2 x 4 lumber or heavier. Whenever car-
pet or padding is present, they should be removed including the total
area of the hearth extension (see page 16). Firebox will be installed 1/2"
in front of the framing so that installed 1/2" sheetrock will be flush with
opening.
Fire-blocking is required between the joists in which the flue will be in-
stalled. An enclosed chase should be constructed with a minimum open
clear space specified by I.D. Chase Size in TABLE 1, Page 7.
When an exterior roof chase is constructed (see FIG. 1), a ½" plywood or
wafer board should cap the chase in which a minimum diameter circle, of
2" larger than the pipe diameter, should be removed, and over which the
roof flashing should be centered and mounted.
THE FIREPLACE CANNOT BE USED AS ANY PART OF A STRUCTURAL
OR LOAD BEARING WALL.
