REGULATORY INFORMATION
WARNING ABOUT HOT WATER
Rinnai Australia 2 Operation Manual
FEATURES AND BENEFITS
Congratulations on purchasing the latest technology temperature controlled Rinnai continuous flow
water heating system.
• The Rinnai Continuous Flow water heater products NEVER RUN OUT of hot water. Whilst
electricity , wa ter and gas su pplies are conn ected, hot water is available when ever hot water t ap s are
open.
• Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEMPERATURE of the
hot water supplied. The water temperature may be limited to various values. This is particularly
useful when the hot water unit is installed where young children or the infirm may be using the hot
water.
• The Rinnai Continuous Flow water heater products are power flued appliances. This makes them
COMPACT, saving both floor and wall space.
• The temperature of hot water is CONSTANTLY MONITORED by a BUILT-IN SENSOR. If the
temperature of the hot water rises to more than 3°C above the selected temperature the burner is
turned OFF and only turned ON again when the temperature falls below the selected temperature.
• The burner lights automatically when the hot water tap is opened, and goes out when the tap is
closed. IGNITION IS ELECTRONIC, so there is no pilot light. When the hot water tap is off, no gas is
used.
• The "Smartstart®" system when fitted can pre-heat the water in the pipework between the water
heater and the hot water outlets. This results in water savings and reduces waiting time for heated
water at the outlets.
• 'Deluxe' or 'Universal' Water Controllers are available as an optional extra. Depending on the
models chosen, these offer the following features:
• Bath fill function (Deluxe Bathroom Control Only).
• Voice Prompting (Deluxe Control Only).
• Clock (Deluxe Control Only).
• Up to four water controllers can be fitted. See page 6 for details.
• Water controller cables are connected easily by the end user using a convenient quick connect
system.
• Operating NOISE LEVEL IS VERY LOW.
• ERROR MESSAGES ARE DISPLAYED on the Water Controllers and Status Monitor*, assisting
with service. *Status Monitor available on INFINITY 26 Plus (REU-VRM2630WD), HD250e (REUVRM3237WC), HD200e (REU-VRM2632WC) and HD200i (REU-VRM2632FFUC) models only.
Rinnai Australia 3 Operation Manual
IMPORTANT INFORMATION
The range of Rinnai continuous flow water heaters referred to in this manual are
incompatible with solar water heating systems. A dedicated range of solar
compatible continuous flow water heaters is available from Rinnai.
Always check water temperature carefully before
use. Refer to the WARNING ABOUT HOT WATER
on "page 1" of this manual for important safety
information.
At low water flows, the hot water unit may exti ngu ish
without warning. Opening the tap further will restart
the appliance.
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.
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, turn off water and
gas and drain all water from the appliance . If power
and the automatic frost protection are connected,
freezing will be prevented. (Anti-frost protection is
fitted as standard equipment on External units and is
available as an optional extra on Internal Units)

Rinnai Australia 4 Operation Manual
IMPORTANT INFORMATION
To clean your water controller(s) use a soft
damp cloth with a mild detergent.
Do Not use solvents!
Whilst hot water outlets are open the set
temperature may be lowered. However they
cannot then be raised above 43°C. In addition
transfer of 'priority' between controllers is not
possible. These are safety features.
Depending on the weather conditions and the
length of the pipe between the hot water unit
and the outlet in use, there may be a variation
between the temperatures displayed at the
water controller(s) and the temperature of the
water at the outlet.
There is no need to turn the water controller(s)
off after use. However, if you prefer to turn the
water controller(s) off, selected temper atures
to a maximum of 50°C will be stored in the
system memory at all times whilst mains power
remains connected.
As a safety precaution, if a Kitchen Controller's
temperature is set above 50°C, transferring
and then returning 'priority' to the Kitchen
Controller will result in a default set
temperature of 50°C being se lected. This is a
safety feature.
Do Not push the On/Off button on any
Controller when the ‘Red’ water heater ‘In Use’
indicator is illuminated as this will turn off the
water heater causing the water to go cold.
