Pressure & Temperature Relief
Valve
The Pressure & Temperature Relief Valve
is supplied loose with the water heater.
Please refer to the specifications
table on page 6 for the valve ratings.
The PTR valve must be installed directly
into the top socket marked “RELIEF
VALVE”. The drain line from this valve
must run in a continuously downward
direction in a frost-free ambient position
with the discharge end left open to
atmosphere permanently.
The PTR Valve is not intended to enable
connection of the water heater to
supplementary energy sources such as
solar panels or slow combustion stoves
(refer AS/NZS 3500.4 for guidance on
these types of installations).
Open the PTR Valve for approximately
10 seconds by lifting the lever on the
valve to ensure water is relieved to waste
through the relief drain pipe. Lower lever
gently and check that it closes correctly.
The PTR Valve must not be tampered
with or removed. The water heater must
not be operated unless this valve is
fitted and in working order.
The PTR Valve should be checked for
adequate performance or replaced at
intervals not exceeding 5 years, or less
in areas where local regulations apply.
Important: The PTR Valve and its
drain outlet pipe must not be sealed or
RIN0421
023335
Rev. A
blocked. It is normal for the PTR valve
to leak a small amount of water during
heating cycles.
Danger
Failure to operate the relief valve easing
lever at least once every six (6) months
may result in a problem with the water
heater and in some cases the tank may
explode.
Warning: A separate drain line must be
run for this relief valve. It is not permitted
to couple drain lines from relief valves
into a single common drain line.
Note: Brass plugs are supplied with
the water heater to plug off the unused
fittings. Ensure that a sealing material is
applied to the plugs to prevent leaking.
Cold Water Connection
An approved isolating valve, non
return valve, line strainer (optional but
recommended), and union must be
fitted between the supply main and
either of the RP¾/20 sockets marked
“Inlet” at the bottom of the water heater.
All fittings must be approved by the
relevant Authority. See the diagram on
page 4 for details.
Note for S.A. and W.A.: It is a state
requirement that a pressure relief valve
be fitted on the cold water supply line
between the non return valve and the
water heater. See the diagram on page
4 for details.

Hot Water Connection
The hot water pipe should be connected
to either of the RP¾/20 sockets marked
OUTLET at the top of the unit. For the
most economical operation of the water
heater, it is recommended that all hot
water lines are insulated. Please check
local regulations regarding the use of
hot water supply pipework that are not
made of copper.
Inlet Connections
Temperature Protection
Water heaters can produce very hot
water. To reduce the risk of scald injury,
it is mandatory under the requirements
of Australian Standard AS/NZS3500.4.2
that a suitably approved temperature
control device be fitted to the hot water
supply to outlets used primarily for
personal hygiene. This valve should be
checked at regular intervals to ensure its

Electrical Connection
This water heater is designed for
single phase 240V A.C supply only.
The electrical connection must
comply with Local Supply Authority
Regulations and AS/NZS3000.
Danger: The operation of the thermal
cut-out indicates a possibly dangerous
situation. Do NOT reset the thermal
cutout until the water heater has been
serviced by a qualified person.
For models pre-wired with a flexible
lead, if the supply cord is damaged, it
must be replaced by the manufacturer,
its service agent, or similarly qualified
person in order to avoid hazard.
Caution: Water heater must be filled
with water before turning on the

Entry to the connection area is through
the hole beneath the element cover,
designed to accept a 20mm conduit.
The element cover may be removed by
undoing the two screws on the cover
and sliding the cover downwards to
disengage the top edge. Ensure that the
conduit entry is well sealed to achieve
correct weatherproofing.
Note: This water heater is fitted with
a thermostat and over-temperature
energy cut-out. Under no circumstances
should the water heater be operated
without both these devices being in the
circuit. Replacement must be carried
out only by a qualified electrician or the
manufacturer.

Operating Instructions
Safety
This appliance is not intended for use
by persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been given
supervision or instruction concerning
use of the appliance by a person
responsible for their safety.
Children and animals should be
supervised to ensure that they do not
interfere with the appliance.
Filling The Water Heater
Open all hot water taps. Open isolating
valve at the cold water inlet slowly and
allow water heater to fill until water flows
through the system. Close each hot
water tap after the air is expelled from
its line. As noted previously power is not
to be turned on until the water heater is
filled with water.
where the TDS exceeds 600mg/L it
is possible that the magnesium alloy
anode (supplied in the heater) may
become over-reactive. To alleviate this,
the magnesium alloy anode should be
replaced with an aluminium alloy anode,
available from your local Rinnai supplier.
Water can also be very corrosive, the
measure of this is the saturation index.
If the water saturation index is greater
than 0.40, an expansion control valve
should be fitted. If the index is greater
than 0.80, the water heater installed
should be a Hard Water Model. Please
consult our Service Department for
advice if required.
Water Quality
Your Rinnai water heater has been
manufactured to suit water conditions of
most Australian metropolitan supplies.
Please note that harsh water supplies
can have a detrimental effect on the
water heater and its life expectancy. If
you are unsure about your water quality
you can obtain information from your
local water supply authority.
Caution
If the water heater is left in an operating
condition and unused for two weeks or
more, a quantity of hydrogen (which is
highly flammable) may accumulate in the
top of the water cylinder. To dissipate
this gas safely it is recommended that
a hot tap be turned on for several
minutes at a sink, basin or bath, but not
a dishwasher, clothes washer or other
appliance. During this procedure there
must be no smoking, open flame or
any other electrical appliance operating
nearby. If hydrogen is discharged
through the tap it will probably make an
unusual sound as with air escaping.
The water heater is designed for use
in areas where the Total Dissolved
Solids (TDS) content of the water
supply is less than 2500 mg/L. In areas
Where the water heater is not
installed in accordance with the listed
advice, the water heater will not be
covered by the Terms of Warranty.

machines and dishwashers can
be under estimated. Review these
appliances to determine if your
daily usage is greater than the
storage volume of your water
heater. For example, if you have
a 315 litre storage tank and you
are using 450 litres of water it is
possible that there will be certain
times of the day where there is
insufficient hot water. It is also
advisable to inspect tap washers
etc. for leakage and replace if
necessary.
What Should I Check Before
Making A Service Call?
If there is not enough hot water, it is
recommended that the following points
be considered before making a service
call. If after checking the following points
the problem has not been identified,
please contact Rinnai on 1300 555 545.
No Hot Water
• Is the Pressure & Temperature Relief
Valve discharging too much water?
•
Do you have the correct size water
heater for your requirements? Sizing
details are available from your Rinnai
supplier.
•
Is one outlet (such as the shower)
using more hot water than you think?
•
Carefully review the family's hot
water usage and if necessary
check the shower flow rates with a
bucket, measuring the amount of
water used over that period of time.
If it is not possible to adjust water
usage patterns, an inexpensive flow
control valve can easily be fitted to
the shower outlet.
•
Consider that during night time
heating, the time taken to heat
the tank can take longer so you
may find that the tank has not fully
recovered from a period of heavy
usage the previous evening.
•
Consider that often the hot water
usage of showers, washing

•
Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water.
•
Replace faulty tap washers and
have your plumber rectify any
leaking pipe work.

Water Discharge from the PTR
Valve
Pressure & Temperature Relief Valve
(PTR)
It is normal for the PTR to allow a small
quantity of water to escape during the
heating cycle. The amount of discharge
will depend on hot water usage.
High Electricity Bills
• Is the Pressure & Temperature
Relief Valve discharging too much
water?
•
Is one outlet (such as the shower)
using more hot water than you
think? See “No Hot Water”.
•
Is there a leaking hot water pipe
or dripping hot water tap? A small
leak can waste a large quantity of
hot water.
•
Replace faulty tap washers and
have your plumber rectify any
leaking pipework.
Continuous trickle (PTR)
This is most likely due to a build up of
foreign matter. In this case try gently
raising the easing lever on the Pressure
& Temperature Relief Valve for a few
seconds then release gently. This may
dislodge a small particle of foreign
matter and rectify the fault.
Steady flow (PTR) – more than 20L per
day
This may be caused by excessive water
supply pressure, a faulty Pressure &
Temperature Relief Valve or a faulty
thermostat. Turn off the electricity supply
and contact Rinnai.
