Commissioning
AS/NZS 5601.1, clauses 2.6.8 and 6.11.2. states that every part of the gas installation shall be
commissioned prior to initial use. It is the installer's responsibility to ensure all current AS/NZS
5601 requirements are met.
The appliance must be tested after installation. Ensure the building occupants do not have
access to the hot water outlets during this procedure.
WARNING
Please note
The Rinnai INFINITY HD56kWe model comes with a factory preset outlet temperature of 55°C. The
high and low gas operating pressures are also factory preset. Under normal operating conditions
the operating pressures do not require adjustment during installation. Make adjustments ONLY if
the unit is not operating correctly and all other possible causes for incorrect operation have been
eliminated.
Inlet supply pressure MUST BE checked and set within the operating parameters of the appliance
in all instances. If the appliance cannot be adjusted to perform correctly call 0800 RINNAI (0800
746 624) for assistance.
