3.1 PARAMETERS MENU
For safety reasons, it is advisable not to modify the parameters of the menus without having fully
understood the meaning of the parameters themselves and the consequences produced on the
boiler.
It is recommended to always contact Rinnai Italia in advance so as not to damage the boiler or the
plant to which it is connected and to exclude potential risks for the user.
