combustible wall with a minimum of 12-in brick
separation from clay liner to combustibles.
the fireclay liner shall run from outer surface of brick
wall to, but not beyond, the inner surface of chimney
flue liner and shall be firmly connected in place.
B
Solid-insulated, listed
length of the same inside diameter as the chimney
connector and having 1-in or more of insulation with
a minimum 9-in air space between the outr wall of
the chimney length and combustibles.
C
