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
