*SIZE TERMINATION PIPE PER TABLE 8.

NOTE - Do not discharge exhaust gases directly into any chimney or vent stack. If ver­ tical discharge through an existing unused chimney or stack is required, insert piping inside chimney until the pipe open end is above top of chimney and terminate as illus­ trated. In any exterior portion of chimney, the exhaust vent must be insulated.

FIGURE 46

Details of Exhaust Piping Terminations for Non‐Direct Vent Applications

Exhaust pipes may be routed either horizontally through an outside wall or vertically through the roof. In attic or closet installations, vertical termination through the roof is pre­ ferred. Figures 47 through 50 show typical terminations.

1 - Exhaust piping must terminate straight out or up as shown. The termination pipe must be sized as listed in table 8.The specified pipe size ensures proper veloc­ ity required to move the exhaust gases away from the building.

2 - On field supplied terminations for side wall exit, ex­ haust piping may extend a maximum of 12 inches (305MM) for 2” PVC and 20 inches (508MM) for 3” (76MM) PVC beyond the outside wall. See figure 48.

3 - If exhaust piping must be run up a side wall to position above snow accumulation or other obstructions, pip­ ing must be supported every 24 inches (610MM) as shown in figure 49. When exhaust piping must be run up an outside wall, any reduction in exhaust pipe size must be done after the final elbow.
