NOTE - Do not discharge exhaust gases directjy 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 42
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 43 through 46 show typical terminations,
1 - Exhaust piping must terminate straight out or up as
shown, The termination pipe must be sized as listed in
table &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 44.
