New Buck Corporation 74 installation instructions

3.Measure up so there will be at least 1/4" rise per foot of horizontal connector pipe, maintaining clearances to the ceiling as noted in (Figure 6 Page 14.) This will give you the center of the hole for the chimney penetration.

4.After locating the center of the penetration, install the tee-box and chimney as per the chimney manufacturer's specifications.

5.Connect the chimney connector to the tee-box using #24 ga. minimum blue or black steel connector pipe. DO NOT use galvanized pipe. Connect each section so the crimped end faces downward, and secure each section to each other using three (3) sheet metal screws or rivets. (See Figure 7.)

C. Wall Exit Into Masonry Flue (Using Single Wall Pipe.)

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.
