3. Measure so there will be at least
1/4" rise per foot of horizontal
connector pipe, maintaining
clearances to ceiling as noted in
Figure 16. This will give you the
center of the hole for chimney
penetration.
4. After locating center of
penetration, install tee-box and
chimney as per chimney
manufacturer's specifications.
5. Connect chimney pipe to tee-box
using #24 ga. minimum blued or
black steel pipe. (DO NOT use
galvanized pipe.) Each section
should fit into section below or
into opening on stove, for drip-
free operation. Secure each
section together by using at least
three (3) sheet metal screws or
rivets.
Wall Exit Into Masonry
(Using Single Wall Pipe)
1. Before connecting Model 91
Bay to a masonry chimney,
determine if masonry fire-
place wall pass-through connector
thimble meets NFPA-211 Code and local building codes and is a minimum of 18" from ceiling. If
connector thimble does not meet these codes, the pass-through connector must be modified.
Connectors may pass through walls or partitions constructed of combustible material if connector is:
(a) Either listed for wall pass-through or is routed through a device listed for wall pass-through and is
installed in accordance with conditions of listing.
(b) Selected or fabricated in accordance with conditions and clearances as stated in NFPA 211-Code. Any
unexposed metal that is used as part of a wall pass-through system and is exposed to flue gases shall be
constructed of stainless steel or other equivalent material that will resist corrosion, softening, or cracking
from flue gases at temperatures up to 1800
In addition, a connector to a masonry chimney shall extend through wall to the inner face or liner but not beyond,
and shall be firmly cemented to masonry.
EXCEPTION: A thimble may be used to facilitate removal of chimney connector for cleaning, in which case
thimble shall be permanently cemented in place with high temperature cement.
2. Once through-the-wall thimble codes are met, simply connect chimney pipe to the wall pass-through
connector using #24 ga. minimum blued or black steel pipe as follows:
(a) Maintain 1/4" rise per foot (horizontal length) from the appliance to chimney.
(b) Each section of pipe should fit into section below or into opening on the stove for drip-free operation.
(c) Secure each section to each other using at least three (3) sheet metal screws or rivets.
