NOTE: When using 3" (7.6 cm) vent pipe, use two 3" (7.6 cm) to 2" (5.1
cm) reducers for each portion of the vent. One reducer is installed just
after the blower and the other reducer is used just prior to exiting the
building. Exit the building wall with 2" (5.1 cm) vent pipe using the 2" (5.1
cm) 45 vent terminals supplied. Two 45 elbows are equivalent to one
90 elbow.
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.
