Commissioning
AS/NZS 5601.1, clauses 2.6.8 and 6.11.2,
states that every part of a 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 URL’s
provided are links to short videos on how key
steps are performed.
The appliance operation must be tested
after installation. Ensure the building
occupants do not have access to the
hot water outlets during this procedure.
Please note
The Rinnai INFINITY EF26 and A-Series come
with a factory preset outlet temperature of
55 °C. The high and low gas operating
pressures are also factory preset. Under
normal 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 to the appliance MUST
BE checked and set within the operating
parameters of the appliance in all instances.
If the appliance can not be adjusted to perform
correctly call 0800 RINNAI (0800 746 624) for
assistance.
