* 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). FIELD SUPPLIED WALL TERMINATION 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). FIELD SUPPLIED WALL TERMINATION Figure 32 5. 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 31 and 32. 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 31 and 32. 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 31 and 32. When exhaust and intake piping must be run up an with pipe sized per Table 6. 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. 8. A multiple furnace installation may use a group of up to four terminations assembled together horizontally, as shown in Figure 35.

If vertical 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 terminates as illustrated. In any exterior portion of chimney, the exhaust vent must be insulated. Figure 36 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 preferred. Figures 37 through 40 show typical terminations. 1. Exhaust piping must terminate straight out or up as shown. The termination pipe must be sized as listed in Table 6. The specified pipe size ensures proper velocity required to move the exhaust gases away from the building. 2. On field supplied terminations for side wall exit, exhaust piping may extend a maximum of 12 inches (305 mm) for 2” PVC and 20” (508 mm) for 3” (76 mm) PVC beyond the outside wall. See Figure 38. 506501-01 Issue 1031 Page 27 of 48 NON-DIRECT VENT ROOF TERMINATION KIT (15F75 or 44J41) NON-DIRECT VENT ROOF TERMINATION KIT (15F75 or 44J41) Figure 37 NON-DIRECT VENT FIELD SUPPLIED WALL TERMINATION Figure 38 3. If exhaust piping must be run up a sidewall to position above snow accumulation or other obstructions, piping must be supported every 24” (610 mm) as shown in Figure 39. When exhaust piping must be run up an outside wall, any reduction in exhaust pipe size must be done after the final elbow. NON-DIRECT VENT FIELD SUPPLIED WALL TERMINATION EXTENDED OR (15F74) WALL TERMINATION VENT PIPE EXTENDED * Use wall support every 24” (610 mm). Use two supports if extension is greater than 24” but less than 48”. Figure 39 NON-DIRECT VENT APPLICATION USING EXISTING CHIMNEY NOTE: Do not discharge exhaust gases directly into any chimney or vent stack. If vertical discharge through an existing unused chimney or stack is required. Insert piping inside chimney until the pipe open end is above top of the chimney and terminates as illustrated. In any exterior portion of chimney, the exhaust vent must be insulated. Figure 40 Condensate Piping This unit is designed for either right or left side exit of condensate piping in upflow applications. In horizontal applications, the condensate trap must extend below the unit. An 8” service clearance is required for the condensate trap. Refer to Figure 41 for condensate trap locations. Page 28 of 48 Issue 1031 506501-01 CONDENSATE TRAP AND PLUG LOCATIONS (Unit shown in upflow position) NOTE: In upflow applications where side return air filter is installed on same side as the condensate trap, filter rack MUST be installed beyond condensate trap or trap must be relocated to avoid interference.
