* MBH = 1,000 Btuh = British Thermal Unit Per Hour. Boilers are equipped for altitudes up to 2,000 feet only. U.S.A. Only - For altitudes above 2,000 feet, ratings should be reduced at the
rat of 4% for each 1,000 feet above sea level. Canada Only - Boilers may be used at high altitude by using a certified field conversion, kit, resulting in a 10% de-rate.
+ Heating Capacity based on D.O.E. (Department of Energy) test procedure.
New York City MEA Number 484-84-E Vol. IV.
The Ratings marked "Net I=B=R Ratings" indicate the
amount of remaining heat input that can be used to heat
the radiation or terminal units. The Net I=B=R Ratings
shown are based on an allowance of 1.15 in accordance
with the factors shown on the I=B=R Standard as
published by The Hydronics Institute.
