HOW TO LOCATE CHIMNEY EXIT, AND INSTALL
E. Vertical exit into
masonry flue
using (6" Single Wall pipe minimum 24 ga. blued or
black pipe with Elbow).
With standard close clearance shield and pipe shield.
NOTE: For minimum clearances (See Page 17, Figure 11).
1. Before connecting these units to a masonry chimney, determine that the masonry flue
pass-through connector thimble meets the NFPA-211 Code, and local building codes,
and is a minimum of 18" from the ceiling. If the connector thimble does not meet
these codes, the pass-through connector must be modified.
NOTE: When using 24# ga. minimum blue or black steel pipe,“maintain 18"minimum
clearances" between pipe and ceiling.
Connectors may pass through walls or partitions constructed of combustible material if the
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 the conditions of the listing.
(b) Selected or fabricated in accordance with the conditions and clearances as stated in
the 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 1800o F.
In addition, a connector to a masonry chimney shall extend through the 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 the chimney connector for
cleaning, in which case the thimble shall be permanently cemented in place with
high-temperature cement.
2. Once the through-the-wall thimble codes are met, simply connect the chimney collar
with elbow to the wall pass-through connector using #24 ga. minimum, blue or black
steel connector pipe as follows:
(a) Maintain 1/4" rise per foot (horizontal length) from the appliance to the chimney.
(b) Connect each section so the crimped end faces downward.
(c) Secure each section to each other using at least three (3) sheet metal screws or rivets.
(d) Use three (3) sheet metal screws to fasten pipe to New Buck Cast Collar onto heater.
after New Buck Cast Collar Part# MA6CHIMCNB has been attached to stove.
