Installation
Positioning
The Rinnai Continuum should be positioned so there is access to any parts that may
need servicing. It should be possible to remove the appliance at a later stage without
altering the structure of the building.
If the water heater is remotely fitted then it should be positioned as close to the unit as
practicable to ensure minimum heat loss.
The tank must always be restrained with seismic restraints as per NZ5261 and the local
building codes.
The Appliance should always be installed to the applicable codes and suggested siting
positions can be found on the next page.
Temperature & pressure relief valves
The appliance is fitted with temperature and pressure relief valves that are rated for the
Rinnai continuum (external model only). For remote usage the pressure and
temperature relief valves should be sized and fitted according to the heat input of the
Infinity water heaters. The relief should be as short as possible and grade continually to
drain without restriction.
Cold water supply
The cold water inlet to the Rinnai Continuum should be a minimum of 150kPa and not
exceed 500kPa. If the water pressure is in excess of 500kPa then a pressure reducing
valve should be fitted. A stopcock, pressure limiting valve, line strainer, cold water
expansion valve and non-return valve are required for all installations of the continuum.
Appliance connections
Primary flow and returns are 20mm-bsp female connections and the secondary flow and
returns are 50mm-bsp female connections, which can be bushed down or capped as
required. Both the hot water outlet on the top of the cylinder and cold water inlet are
50mm-bsp female connections.
