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.

Details of Exhaust Piping Terminations for
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 40 through 43 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 exits, ex- haust piping should extend a maximum of 12 inches (305mm) beyond the outside wall, unless support is provided in the horizontal section. See figure 41.
