Rinnai Australia 22 Owners Guide & Installation Instructions
GENERAL INSTALLATION INSTRUCTIONS
Your Rinnai HD200 Series Continuous Flow Water Heaters have a self diagnostic capability. If a fault
occurs, an Error Code will flash on the Digital Monitor.
INFINITY HD Fault Codes:
Ring Main Pump:
• These are used for circulating water around the building. They are normally left on or may have a
time clock to switch it OFF at night when the building is not in use.
• These pumps need to develop sufficient head to deliver the designed flow rate.
• They must have a non return valve.
• Swing non return valves must be horizontal or upward as they rely on gravity to close the valve.
Upward direction may cause noise issues as valve opens and shuts.
• Spring isolation valves can be located on any plane but may contribute excessive back pressure
and restrict the pump flow rate.
• Return water should only be slightly cooler than water leaving the tank. If the temperature drop
around the circuit is too high it may indicate excessive heat loss due to poor insulation, the ring
main pump flow rate is not high enough or indicates a design fault or a blockage in the pipe work
(or poor pipe work insulation). Investigate insulation, valves and operation of pump.
Service:
Rinnai recommend that all commercial water heater installations have a service arrangement. Annual
services are recommended at a minimum. Refer to the back cover for contact information.

In all cases, you may be able to clear the Error Code simply by turning the hot water tap OFF, then ON again. If this does
not clear the Error Code, try pushing the On/Off button OFF, then ON again. If the Error Code still remains, contact Rinnai
for advice.
