WARNING ABOUT HOT WATER
APPLICATIONS

Rinnai Australia 2 RA TSD 10-019 Op/Ins Solar Hot Water - Issue 3.0 30/05/11
FEATURES AND BENEFITS
• The Rinnai solar range of continuous flow water heaters NEVER RUN OUT of hot water even during times
of limited solar radiation and/or high hot water demand. Whilst the electricity, water and gas supplies are
connected, hot water is available whenever hot water taps are open.
• The Rinnai solar range of continuous flow water heaters are power flued appliances. This makes them
COMPACT saving both floor and wall space.
• IGNITION IS ELECTRONIC, so there is no pilot light. When the hot water tap is off, no gas is used.
• Operating NOISE LEVEL IS VERY LOW.
• The "Smartstart®" system (when fitted) can pre-heat the water in the pipework between the continous flow
unit and hot water outlets. This results in water savings and reduces waiting time for heated water at the
outlets.
Always check water temperature carefully before use. Refer to the WARNING
ABOUT HOT WATER on "page 1" of this information document for important
safety information.
Do Not touch the unit cover or the flue outlet.
Do Not insert objects into the flue outlet.
On colder days steam may discharged from the flue outlet. This condition is normal
for high efficiency appliances and does not indicate a fault
At low water flows, the hot water unit may extinguish without warning. Opening the
tap further wil restart the appliance.
Keep flammable materials, spray cans, fuel containers, pool chemicals, trees,
shrubs, etc. well clear of the flue outlet.
Do Not spray water directly into the flue terminal.
If freezing conditions are expected, ensure the electric power supply to the gas
booster remains ‘ON!’.
This will assure the automatic Anti-frost protection can operate when required.
These are outlined in detail in the following Rinnai publications:
• Installation / Operation Manual Rinnai Solar "Split" systems - Electric and Gas Boosted
• Installation / Operation Manual Rinnai Solar "Close Coupled " systems - Electric and Gas Boosted.
These publications are supplied with the Rinnai Solar storage hot water tank and should have been handed
to the end user by the system Installer. If a copy of either of these publications is required please contact
Rinnai.
