ELBOWS (STAINLESS STEEL, GALVANIZED) 2. Attach the elbow to the chimney pipe or other support part and twist to lock. Using the offset chart, add chimney sections between elbows. A support band (TGSB) is required at the upper elbow of the pair to support the load, as shown in FIG. 16 . Attach the upper elbow to bring chimney back to vertical. Offset combinations: see Table 3 and illustration, FIG. 17. TEE (STAINLESS STEEL, GALVANIZED) ELBOW INSTALLATION 1. Metal-Fab provides a 15 ° (TGA15) and 30 ° (TGA30) Elbow to allow chimneys to avoid framing member or roof peaks. A maximum of 30 ° from the vertical is allowed, and a total of four elbows (two pair) for each chimney installation. Maintain 1-1/2” clearance to combustibles for 6” - 8” diameters and 2” clearance to combustibles for 10” - 12” diameters. W/ INCLUDED TEE CAP 2.

6” GALVANIZED 2. Install the next TG chimney section through the roof. See FIG. 18 . For 12” chimney only, install a radiation shield (TGRSH) over the chimney section so that the shield straps can be temporarily bent over the roof to hold in place. After installing the flashing, these straps will be attached to the flashing as shown in FIG. 19 . NOTE: If your roof is already shingled, be sure to slide the upper edge under the shingles to prevent leakage. 7” GALVANIZED 6” GALVANIZED FLASHING INSTALLATION 1. Continue the TG chimney to the roof. Cut the roof opening, centered over the chimney. A 1-1/2 inch for 6” - 8” diameters and 2 inch for 10” - 12” diameters, airspace around the chimney is required as it penetrates the roof. The size of hole in the roof will vary depending on the roof pitch. See note for Table 1 regarding special 8TG clearances. FLASHING INSTALLATION 1. Continue the TG chimney to the roof.
