* MBH = 1,000 Btuh. Btuh = British Thermal Unit Per Hour
**Add 5V_' to height for Vent Damper.
t For altitudes above 2,000 ft. ratingsshould be reduced at the rate of 4% for each 1,O00 ft above sea level.
Heating Capacity is based on DOE {Department of Energy} test procedure
The City of New YorkMEA Number 77-91-E.
The Ratingsmarked "Net I=B=RRatings" indicate the amount
of equivalent direct cast iron radiation each boiler will take
care of under normal conditions and thermostatic control.
The Net I=B=R Steam Ratings shown are based on an
allowance of 1.333 in accordance with the factors shown
in the t=B=RCode as published by The Hydronics Institute.
Selection of boiler size should be based upon "Net I=B=R
Rating" being equal to or greater than installed radiation in
square feet. Consult manufacturer before selecting a boiler
for installations having unusual piping and picku!_\
requirements.
Specifications and dimensions are subject to change without
notice.
