1.Ratings shown are for installations at sea level and elevations up to 2,000 ft. For elevations above 2,000 ft., ratings should be reduced at the rate of four percent (4%) for each 1,000 ft. above sea level.

2.Capacities, outputs and ratings are based on steam combustion efficiency of 82.5%. Water combustion efficiency is 83.5%.

3.For Canadian builds only: Reduce input and output and 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".

Working Pressure: 15 PSI Steam; 30 PSI Water
