,
and/or ). The frost protection will remain active. Leave gas supply open.
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.

You can try to reset the boiler by pressing the Reset key once. If the problem
remains please contact your installer and inform them about the fault and give
them the number code.
If, on the screen the message “Service” appears, the installer must perform maintenance according to the installation and service manual. Please contact your installer.
We advise you to obtain a service contract with your installer for regular maintance and adjustment to keep your boiler safe and in good condition.
If you discover any leaks from the boiler contact your installer.
The casing of the boiler consists of metal and plastic parts which can be cleaned with a normal non abrasive cleaning agent.
