About your Rinnai Boil & Brew
The Rinnai Boil & Brew is a permanently
plumbed, wall-mounted electric water heater
with an insulated hot water container. Water
is heated by an electric heating element and
the temperature is controlled by a thermostat.
As boiling water is drawn off, the unit refills
with cold water. Any steam generated during
the heating cycle is condensed and retained
within the unit.
The easy to use lever tap is positioned far
enough away from the spout to ensure
steam-free handling. The spout is designed to
minimise splashing when dispensing water.
Automatic reheating
Once installed the filling and heating cycle is
completely automatic.
To use
Place a cup under the outlet spout and pull
the tap handle down. The tap handle is spring
loaded, when released it will spring back to
the off position.
If for some reason you need to dispense a
large volume of water or empty the unit the
tap handle can be pulled up and locked into a
continuous flow position.
Switching off
If not connected to a timer we suggest
switching the unit off if not being used for a
period of time, for example over a weekend.
When not in use
If the unit has been switched off for a long
period of time (for example, for over a week)
it is advisable to draw off the water in the unit.
This will ensure freshly boiled water, not stale
water, is used to make your drinks.
Similarly, if left unused it is possible that some
scale residue will collect in the outlet tap. This
will cause the outlet water to appear milky for
a short while. If this occurs it is recommended
that the first few cups are drawn off and
discarded.
Areas prone to freezing
Care must be taken to prevent the unit
freezing. If thought to be frozen it must not be
switched on. It must be left to thaw and must
be inspected to ensure it is undamaged before
use.
Installation by a licensed tradesperson
Only a licensed tradesperson can install,
adjust, maintain, and service the Rinnai Boil &
Brew. Any work carried out by a non-licensed
tradesperson is illegal and will void any
warranty.

Safety
Maintenance
The usage of the unit will determine the
quantity of scale build up.
Hot water systems, like cars, require regular
maintenance and servicing. To ensure
longevity and optimum performance of your
unit we recommend annual inspection and
servicing.
The front cover and spout will require a
periodic wipe to clean any marks/splashes
from use.
Rinnai has a maintenance,
service and spare parts
network with personnel who
are fully trained and equipped
to give you the best advice on
your Rinnai product. Regular
maintenance and servicing is
not covered by the Rinnai warranty.
For help locating a service person in your area
call 0800 RINNAI (0800 746 624).
Front cover
Do not remove the front cover as this will
expose 230 V wiring and must only be
removed by an authorised person.
Damaged components
If any component is damaged it must be
replaced by an authorised person using Rinnai
replacement parts.
Hot water
The water dispensed will at times be boiling
or close to boiling, due caution must be taken
when using the system.
Child supervision
Children should be supervised to ensure they
do not play with any part of the hot water
system.
Supply cord for the 5, 10, and 15 L units
If the supply cord is damaged it must be
replaced by a licensed tradesperson in order
to avoid a hazard. This must be a genuine
replacement part available from Rinnai.

Location and clearances
The Rinnai Boil & Brew stores and dispenses water at or close to boiling point at all times it is
switched on. Due caution must be taken when choosing a location for the product so as to
minimise misuse.
Locate the unit above a sink draining board, close to
a cold water supply and a power outlet. For the 5 L
(RBBW0500), 10 L (RBBW1000), and 15 L (RBBW1500)
models, the location of the socket outlet/plug
should be such as to give the user safe access for
turning the unit on and off. The site should be
dry and waterproof, and in a position that meets
the minimum clearances shown below. These are
required to allow safe access for servicing.
The heater should be positioned at a height to suit
the items being filled.
The Rinnai Boil & Brew must be vertically mounted.
Before installation confirm suitability of all screws and plugs for use with the wall. If unsuitable
due to the wall type provide alternative fixings.
If rear entry services are to be used the necessary holes for these should be prepared prior to
hanging the unit.
Ensure the wall can support the full weight of the unit and that there are no hidden services
(electricity, gas, or water) below the surface of the wall.

Do not connect the power until there is water flowing freely from the faucet.
Failure to do this may cause the heating element to overheat and fail.
General installation information
1. Mount to the wall
Determine the height of the unit and then
screw in the two top mounting screws
(10 g x 40 mm).
2. Remove the cover
Remove the four cover screws nearest the
back. Remove the cover.
3. Fit unit to the wall
Hang the unit to the wall at the two key hole
fixing points provided at the top of the back
plate. Secure the base with the additional
holes provided.
4. Connect water supply
Connect mains water supply* to the outer,
right hand side ½ BSP connector (marked cold
inlet).
If your water supply contains sand, grit or
other suspended particles, fit an additional
filter (not supplied) in the supply line.
Contaminated water may cause a blockage in
the inlet valve.
* Intended for permanent connection to mains water
supply and not through a hose-set.
5. Connect vent/overflow
Connect a ½ BSP copper tube to the left side
½ BSP vent/overflow connector. This overflow
vent must be arranged so as to divert excess
water, steam, or steam condensation into
the sink, or drain, or to the exterior of the
building.
The vent tube must be unrestricted, be
greater than 5 mm OD (to avoid blockage),
have a continuous fall with a clear open end
and must be left open to the atmosphere. It
cannot be connected to an open plumbing
system. Alternatively, providing that you have
sited the Rinnai Boil & Brew over a sink or
draining board, you can vent directly through
the bottom of the unit through the hole
provided.
Make up and connect your overflow vent.
6. Turn on water supply
Turn on the water supply and check for leaks.
Wait until filled and until water flows freely
from the faucet.
7. Refit the cover
Place the cover over the unit and refit the
four screws. Leave the faucet in the closed/off
position. The unit is now ready for filling.
8. Connect the power and switch on
Only do this if there is water flowing freely
from the faucet as failure to do so could cause
the element to overheat and fail.
9. Flush entire system
Draw off as much water as needed to ensure
the system is completed flushed of any
installation materials.
The Rinnai Boil and Brew is now ready to use.

Water quality
The Rinnai Boil & Brew boiling water units are manufactured to suit most NZ
council water supplies. However some water supplies can have a detrimental
effect on the water heater, its operation, and life expectancy.
Hard water
In hard water areas, heated water will produce limescale which will be deposited within the
heater. If this is not regularly removed it will impair the operation of the heater. Scale reducing
or water softening devices should be considered in hard water areas. The unit is not guaranteed
against damage due to scaling.
Water quality outside the limits (as set down below) will void this warranty. Water quality tests
must be carried out at the customer’s own cost but Rinnai will reimburse any reasonable test
costs where water quality is within the limits tabled.
Water Quality and Impurity Limits
TDS (Total Dissolved Solids) Total Hardness CaCO3Dissolved (free) CO2pH Langelier Index
Up to 600 mg/L or ppm Up to 200 mg/L or ppm Up to 25 mg/L or ppm 6.5-8.5 Between -1.0-0.8
Most metropolitan water supplies fall within these limits. If you are unsure about water quality,
please contact Rinnai and we will provide you with the details of an authorised agency able to
test your water for compliance to Rinnai standards. If sludge or foreign matter is present in the
water supply, a suitable filter should be incorporated in the water supply.
Some examples of water quality issues where water may need to be treated:
• Hard water (areas including Wanganui)
• Aggressive water (areas including Christchurch)
• Both hard and aggressive water (some bore water)

Electrical supply and connections
The electrical connection must be carried out by a qualified person in accordance
with NZ Electrical Regulations. The appliance must be connected to a 230/240 V AC
supply. A double pole isolation switch, with a contact separation of at least
3 mm in both poles, must be incorporated in the electrical supply.
• The appliance must be earthed
• Disconnect all power prior to installation and commissioning
• Wiring to the appliance must be capable of withstanding the appliance load
• Fixed wiring must be protected from contact with the appliance
If the appliance is to be unused for significant periods of time running costs can be reduced
by switching the unit off. It is recommended that this is done automatically by incorporating a
suitable timer in the supply to the unit. The timer must be capable of switching a resistive load to
suit the current of the appliance.
25 L fixed wiring unit
The RBBW2500 is supplied without a cord set and must be permanently wired using a switch
isolator and wiring rated at not less than 15 A. Connect the 240 V AC single phase 15 A wiring to
the connector provider.
It is strongly recommended that the electrical supply wiring circuit includes a Residual Current
Device (RCD).
