*SLP98DF −070 and −090 units with the flush−mount ter- mination must use the 1−1/2" accelerator supplied with the kit.

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 20 and 22.

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 20 and 22.

APPLICATION

structions, piping must be supported every 24"

(610mm) as shown in figures 20 and 22. In addition,

close−coupled wall termination kits must be extended

for use in this application. See figures 30 and 31.

When exhaust and intake piping must be run up an

outside wall, the exhaust piping must be terminated

with pipe sized per table 9.The intake piping may be

equipped with a 90° turndown elbow. Using a turn-

down elbow will add 5 feet (1.5m) to the equivalent

length of the pipe.

See venting table 7 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).
