This manual provides general guidelines for piping and installation.Your installation must comply with all applicable local codes.

When using isolation valves on each boiler, some codes may require providing a low water control and additional limit for each boiler. If desired, consult the codes to determine if exclusion of the individual boiler isolation valves may allow the use of a single water level control and additional limit for the entire multiple boiler system.

Part number 550-101-232/0703
