Power Circuit Design:
All Bryan BH Series boilers feature copper bus bar distribu-
tion, wherein the fuse clip for each branch circuit and the
main power lugs are all bolted directly to a bus bar. The
bus bar can carry the full load current of the
boiler, withstanding the largest available fault
current from the entering power system. Use of
the bus bar protects all current-carrying parts
and prevents damage to the boiler.
Optional Equipment Available:
Power panel door electric interlock. Preheat
switch. Flow switch. Manual reset controls.
Manual blowdown valve. Automatic blowdown
with 24 hour time clock. Alarms. Indicating
lights. Larger connection for heat pump
