1. Capacities and ratings are based on steam combustion efficiency of 83.0%.
(84.1% for PIN3PV)
2. The approved venting system for the Independence PV is 3” AL29-4C
®
stainless steel. Do not
substitute other materials.
3. Vent pipe length is listed in equivalent feet. Any elbows or tees used can have specific values
which must be subtracted from the total length to determine maximum length of straight pipe.
Consult Installation, Operating, and Service Instructions for details.
