(15F74) WALL RING TERMINATION KIT
With INTAKE ELBOW
See venting table 23 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).

5. 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. Intake piping
should be as short as possible. See figures 28 and 29.
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 28 and 29.
7. If intake and exhaust piping must be run up a side wall
to position above snow accumulation or other ob-
structions, piping must be supported every 24"
(610mm) as shown in figures 28 and 29. In addition,
close coupled wall termination kits must be extended
for use in this application. See figures 36 and 37.
When exhaust and intake piping must be run up an
outside wall, the exhaust piping must be terminated
with pipe sized per table 24.The intake piping may be
equipped with a 90° elbow turndown. Using turndown
will add 5 feet (1.5m) to the equivalent length of the
pipe.
8. Based on the recommendation of the manufacturer, a
multiple furnace installation may use a group of up to
four terminations assembled together horizontally, as
shown in figure 33.
