USING EXISTING CHIMNEY
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 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 40 through 41 show typical terminations.
1 - Exhaust piping must terminate straight out or up as
shown. The termination pipe must be sized as listed in
table 10.The specified pipe size ensures proper ve
locity 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.
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).
When exhaust piping must be run up an outside wall,
any reduction in exhaust pipe size must be done after
the final elbow.
