N56 water heaters in the following applications:
- Single unit N56 domestic installations*
- Commercial / showerblock installations with multiple N56 units, as specified by Rinnai commercial
Rinnai INFINITY digital controllers are not compatible with the N-Series pump cable and ring main applications.
* When multiple N56 units are connected together small but noticeable water temperature fluctuations may occur as the load increases and additional units ignite. This is normal operation and not a system fault (warranty). For this reason care should be taken when specifying multiple N56 units in ring main applications where discerning customers may be dissatisfied with minor temperature fluctuations. In these applications please refer to Rinnai commercial for alternative hydraulic arrangements that will be manage these fluctuations—DO NOT use the pump cable.
