* MBH = 1,000 Btuh. Btuh = British Thermal Unit Per Hour.
** Add 5½" to height for Vent Damper
† For altitudes above 2,000 ft. reduce input rate 4% for each 1,000 ft. above sea level.
Heating Capacity is based on DOE (Department of Energy) test procedure.

Add model number suffi x 'P' for Propane Gas.
The net I=B=R steam Ratings shown are based on a piping
and pickup allowance of 1.333.
Base selection of boiler size on "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 pickup
requirements,such as intermittent system operation,
exhaust piping systems, etc.
Specifi cations and dimensions are subject to change
without notice.
