1. Ratings shown are for installations at sea level and elevations up to 2,000 ft. For higher elevations, reduce ratings 4% for each 1,000 ft. above sea level
2. Capacities, outputs, and ratings are based on steam combustion efficiency of 82.5%.
3. For Canadian builds only: reduce input and output by 3%
4. 15 ft. height is measured from top of drafthood to top of chimney.
5. IN6, IN8, & IN10 – Canada only: Increase chimney diameter by 1”
Max Working Pressure: 15 PSI Steam
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.
