40,000, 50,000, 60,000 & 75,000 Btuh Furnaces
40′ (12.2m) & (5) 90° elbows with 2″ (50.8mm) PVC pipe
80,000 & 100,000 Btuh Furnace
40′ (12.2m) & (5) 90° elbows with 3″ (76.2mm) PVC pipe
125,000 Btuh Furnace
40′ (12.2m) & (5) 90° elbows with 3″ (76.2mm) PVC pipe
The minimum vent length is 5’ (1.5m) of PVC. Elbows are DWV Long Radius Type for 2” (50.8mm) and 3” (76.2mm) vents.
If more than five elbows are required, reduce the length of both the inlet and exhaust pipes 5′ (1.5m) for each additional elbow used. If less than five elbow are required, the length can be INCREASED by 5′ (1.5m) for each additional elbow NOT used.
NOTE: It is allowable to use larger diameter pipe and fitting than shown in the tables but not smaller diameters than shown.

Vent Termination Clearances
!WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury or death.
Inlet and outlet pipes may NOT be vented directly above each other.
1.Determine termination locations based on clearances specified in following steps and as shown in Fig. 8, 9, and 22 through 30.
For “Concentric Termination Kit” clearances, see Fig. 32, 33, 34, 35 and 36 in this manual.
2.This furnace is Dual Certified and can be installed as a single pipe appliance (all combustion from inside the structure) or as a direct vent appliance where all combustion air is taken from outside the structure.
3.For Direct Vent installation, refer to Fig. 8 for vent termination.
4.For Single Pipe installation refer to Fig. 9 for vent termination clearances.
