2 Use a solid insulated listed factory-built chimney length having an inside diameter of 6" and having 1" or
more of solid insulation. There must be at lest a 9" air space between the outer wall of the chimney length and
any combustible materials. The inner end of the chimney length shall be flush with the inside of the masonry
chimney flue shall be sealed to the flue and to the brick masonry penetration with nonwater-soluble refractory
cement. Sheet steel supports which are at least 24 gauge (0.024") in thickness shall be securely fastened to
wall surfaces on all sides. Fasteners between supports and the chimney length shall not penetrate the chimney
Liner. See Figure 10. The inside diameter of the fireclay liner shall be sized for the proper snug fit of a 6"
diameter chimney connector pipe. The fireclay liner shall run from the outer surface of the brick wall to, but
not beyond, the inner surface of the chimney flue and shall be firmly cemented in place. (See Page 16 Figure 13).
After all codes have been met, install unit according to (SECTION F Page 15. or SECTION G Page 16.).

3 Use a 10" diameter ventilated thimble made of at lest 24 gauge (0.024") steel having two 1" air channels. The
ventilated thimble must be separated from combustible materials by a minimum of 6" glass fiber insulation.
The opening in the combustible wall shall be covered and the thimble supported with sheet steel supports
which are at lest 24 gauge (0.024") in thickness. The sheet supports shall be securely fastened to wall surfaces
on all sides and shall be sized to fit and hold the chimney section. Fasteners used to secure chimney sections
shall not penetrate chimney flue liner. See Figure 11. The inside diameter of the fireclay liner shall be sized for
the proper snug fit of a 6" diameter chimney connector pipe. The fireclay liner shall run from the outer surface
of the brick wall to, but not beyond, the inner surface of the chimney flue and shall be firmly cemented in
place. (See Page 16 Figure 13).
After all codes have been met, install unit according to (SECTION F Page 15. or SECTION G Page 16.).
