supplier.
These instructions apply to the Manifold Pack range of Rinnai hot water systems using multiple Heavy Duty
continuous flow water heaters to provide large flow rates of hot water.
Rinnai Commercial Manifold Pack hot water systems must only be installed, commissioned, service and removed
by an authorised person in accordance with these instructions, AS/NZS 5601, AS/NZS 3000, AS/NZS 3500 and
local regulations and municipal building codes including local OH&S requirements.
Rinnai Manifold Pack hot water systems are not suitable or approved as a pool heater.
Read these instructions carefully before proceeding with the installation.

LOCATION

Ensure reasonable access for installation, servicing and removal. All valves, controls and pumps etc must be
easily accessible.
When using free standing frames the system must be mounted on a solid level base, capable of supporting the
weight of the appliance when full of water. Ensure components are not allowed to stand in water.
Manifold Pack can be plumbed "left handed", "right handed" or "equal flow" as staging determines operating
sequence of heaters, not the plumbing. Stage-less or larger systems may need to be "equal flow". Contact Rinnai
Commercial for assistance.
Gas booster flue terminals must be located in accordance with AS/NZS 5601 Fig 6.2 "Location of balanced flue
terminals".
Rinnai HD units are fan assisted appliances and thus have lower clearances than a natural draft appliance of the
same MJ rating.

pointing downwards. For appliances installed on elevated structures or under floors specific requirements apply.
Refer to AS/NZS 5601 Section 6 for details.
This appliance must not be used as a domestic spa or swimming pool heater.

NOTE

HD28I, HD210I (INTERNAL MODELS)

These appliances are designed for 'Indoor' installation only. They may be installed 'Outdoors' in an enclosure if the
requirements of AS/NZS 5601 Section 6 are satisfied. An enclosure is defined as a compartment, enclosed area
of partitioned off space primarily used for the installing of the appliance.
If installed in an enclosure either Internally or Externally, the location should be ventilated to allow gas to dissipate
and provision must be made for the safe disposal of any leaking water to a visible location.
This appliance must not be used as a domestic spa or swimming pool heater.
Two types of flue systems are available:
•
The Rinnai Commercial Common Flue System.
•
The Rinnai Co-Axial FFU flue system.
The use of non Rinnai flue components may result in a dangerous situation and violates regulations.
