On field supplied terminations for sidewall exit, exhaust
piping may extend a maximum of 12 inches (305 mm)
for 2” PVC and 20 inches (508 mm) for 3” (76 mm) PVC
beyond the outside wall. Intake piping should be as short
as possible. See Figures 22 and 23.
6.
On field supplied terminations, a minimum distance
between the end of the exhaust pipe and the end of the
intake pipe without a termination elbow is 8” and a
minimum distance of 6” with a termination elbow. See
Figures 22 and 23.
7.
If intake and exhaust piping must be run up a side wall
to position above snow accumulation or other
obstructions, piping must be supported every 24” (610
mm) as shown in Figures 22 and 23. In addition, close
coupled wall termination must be extended for use in
this application. See Figures 22 and 23. When exhaust
and intake piping must be run up an with pipe sized per
Table 7. The intake piping may be equipped with a 90°
elbow turndown. Using turndown will add 5 feet (1.5 m)
to the equivalent length of the pipe.

See venting Table 5 for maximum venting lengths with this
arrangement.
* Use wall support every 24” (610 mm). Use two wall supports if
extension is greater than 24” (610 mm) but less than 48” (1219 mm).
NOTE:
One wall support must be 6” (152 mm) from top of each pipe
(intake and exhaust).
