1 One pressure switch provides on/off operation. Advise desired operation pressure.
2 Two pressure switches used. Each switch controls approximately one half the load and are set at slightly
different settings to allow two step operation. Advise desired operation pressure.
3 Sequence control optional. (Add P to model number). Number of steps based on number of contactors.
See price sheet for description of sequence control.
4 Pressure shown is standard for steam boilers. High pressures is available on special orders.
Sizes 60 KW and smaller are built under ASME "Miniature Code" which may exempt them from
some local and state regulations. Boilers can be furnished with low pressure controls and trim.
