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 preferred.

Figures 39 through 42 show typical terminations.

1. Exhaust piping must terminate straight out or up as

shown. The termination pipe must be sized as listed in

Table 6. The specified pipe size ensures proper velocity

required to move the exhaust gases away from the

building.

2. On field supplied terminations for side wall exit, exhaust

piping may extend a maximum of 12 inches (305 mm)

for 2” PVC and 20” (508 mm) for 3” (76 mm) PVC beyond

the outside wall. See Figure 40.

DIRECT VENT APPLICATION

USING EXISTING CHIMNEY

NOTE

− Do not discharge exhaust gases directly into any chimney or vent st ack. 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.
