The Lochinvar & A.O. Smith 100167804 is a factory-engineered integrated control designed specifically for the AW400 commercial water heater series.

Why Choose an OEM Integrated Control?

Substituting a non-OEM part can introduce reliability risks and void equipment warranties. The 100167804 is engineered to Lochinvar & A.O.
