NOTE: When using 3" (7.6 cm) PVC, use a 3" (7.6 cm) to 2" (5.1 cm)
reducer and exit the building wall with 2" (5.1 cm) PVC using the 2" (5.1
cm) 45 vent terminal supplied. Two 45 elbows are equivalent to one 90
elbow. Each 90° elbow is equivalent to 5 feet (1.5 m) of straight vent pipe.
All of the Venting connections must be leak checked with a soap and
water solution upon initial start up of the water heater. Any leaks must
be repaired before continuing operation of the water heater.
NOTE: ABS or CPVC pipes may be substituted for PVC pipe. Do not mix
ABS and PVC pipe in the same installation.
