3. Measure up so there will be at least 1/4" rise per foot of horizontal connector pipe,
maintaining clearances to ceiling as noted in (Figure 12). This will give you center
of hole for chimney penetration.
4. After locating center of penetration, install tee-box and chimney as per chimney
manufacturer's specifications.
5. Connect chimney connector to tee-box using #24 ga. minimum blue or black steel
connector pipe. DO NOT use galvanized pipe. Connect each section so crimped end
faces downward, and secure each section to each other using three (3) sheet metal screws or
rivets. (See Figure 10. Page 15).

a minimum of 18" from ceiling. If connector thimble does not meet these codes, pass
-through connector must be modified.
NOTE: Floor protector must be under horizontal pipe exit (See Figure 13. Page 19).
