distance between the end of the exhaust pipe and the
end of the intake pipe is 203mm (8 inches).

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. Figure 25 shows a typical terminations.
1 − Exhaust piping must terminate straight out or up as
shown. The termination pipe must be sized as listed in
table 7.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 305mm (12
inches) beyond the outside wall, unless support is pro-
vided in the horizontal section.
