equivalent material that will resist corrosion, softening, or cracking from flue gases at
temperatures up to 1800º F.
NOTE: 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 to
the wall pass-through connector using #24 ga. minimum, blued or black steel conn-
ector 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 or back toward the unit.
(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 connector collar on heater.
D. CEILING EXIT - CLOSE CLEARANCE
1. Suspend a plumb bob from the ceiling above the unit so that the weight is hanging in the
center of the flue exit. (A small weight on a string will serve as a plumb bob.) Mark the
ceiling where the string is suspended to locate the center of the chimney hole.
2. After locating the center of the hole, install the ceiling support box, chimney flashing
and rain cap.
3. Next, install an optional New Buck Corporation chimney connector to the flue exit of the
heater or you may use “Ell” brackets to fasten the pipe to the stove. See Figure 9.
4. Install Single Wall Connector and chimney system per manufacturer’s written operating
instructions. See manufacturer's list of tested pipes in this manual.
