A.O. Smith recommends leaving the power switch switched on to ensure that the
boiler pump(s) and three-way valve (if available) are automatically activated to
prevent them from getting stuck.
If your heating system is not being used during periods of frost we
advise you isolate the power and drain the boiler and the system. In
this case: close the gas valve.

The casing of the boiler consists of metal and plastic parts which can be cleaned with a normal non abrasive cleaning agent.
