CUSTOMER OPERATING INSTRUCTION
How Does My System Work?
The water storage tank is used to store the heated water ready for household use. It has a high
temperature vitreous enamel lining to provide long life, and a high density polyurethane insulation to
ensure minimal heat loss.
Never turn the gas supply off during normal use.
This water heater is designed such that there is little to do regarding system maintenance other than
that detailed in this Owner's Manual.
Personally inspecting or servicing any part of the system is not recommended.
After each 5 years of operation you should contact the local service agent to replace all safety valves
and anodes to ensure continued system life and operational safety. In locations where the water has
a TDS greater than 600 ppm, this service is recommended each 3 years.
By Owner - Six Monthly Service
Operate the Pressure & Temperature Relief Valve for approximately 10 seconds by operating the
easing lever on the valve to ensure water is relieved to waste through the relief drain pipe. Check to
ensure the valve closes correctly.
By Authorised Personnel Only - Five Year Service
The five year service must be carried out by a licensed tradesperson. It is recommended that this
service be carried out by your local Rinnai agent.
The service should include the following:
•
Replace the Pressure and Temperature Relief Valve.
•
Replace the anodes (in areas of harsh or adverse water conditions, a more frequent check of
the anodes is recommended).
•
Flush the water heater by doing the following:
1. Turn off gas supply.
2. Turn off the cold water supply to the water heater at the isolating valve.
3. Gently operate the easing lever on the Pressure & Temperature Relief Valve to release
the pressure in the water heater.
4. Disconnect the cold water inlet union to the heater and attach a drain hose.
5. Gently operate the Pressure and Temperature Relief Valve to let air into the heater and
allow water to escape through the hose.
6. Flush the heater until clear water appears then reconnect all fittings, fill the heater and
restore the gas supply.
All water heaters have the ability to produce hot water in a surprisingly short time.
To reduce the risk of scald injury, it is mandatory under the requirements of
Australian Standards AS 3500 that an Australian Standards approved temperature
control valve be fitted to the hot water supply pipe work. This valve should be
checked at regular intervals to ensure its operation and settings remain correct.
Important there are no user serviceable components in the system. Only an
authorised service representative is permitted to remove any covers or make setting
adjustments.
Do not open or adjust any electrical covers or devices yourself.
