FEATURES AND BENEFITS
Rapid Continuous Flow gas water heaters models R26N, R26P
Whisper Quiet. Your Rapid Continuous Flow water heater operates at a very low noise level.
Electronic Ignition. Your Rapid Continuous Flow water heater lights automatically when the
tap is turned on. No pilot light hassles. When the tap stops, so does the gas.
Micro processor for maximum Safety. The micro processor in your Rapid Continuous Flow
water heater has the ability to limit the maximum temperature of the hot water to protect
young children and elderly residents from scalding.
Compact Flue. Your Rapid Continuous Flow water heater saves on installation space with a
power flue that makes it much more compact.
CONTROLLER FREE OPERATION
Your Rapid Continuous Flow water heater does not use a pilot light. As soon as you open
any hot water tap the appliance will automatically start. Water flowing through the appliance
triggers the electronic ignition to ignite the burner and start heating. When the tap is closed
and the water stops flowing, the burner will stop heating.

IMPORTANT INFORMATION
OFF!
HOT!
Always check the water temperature
carefully before use.
When the water is turned down to a low flow
the heating may extinguish without warning.
To restart the heating open the tap further.
WARNING!! Do not touch the unit cover
or flue outlet. Do not insert objects into
the flue outlet. Steam may discharge on
cold days, this is normal.
KEEP CLEAR! Keep pool chemicals, spray
cans, fuel containers, flammable materials,
garden items clear of the flue outlet. NEVER
spray water into the flue outlet.

HOW TO GET HOT WATER
• Turn on a hot water tap and the heater will automatically light and commence heating
the water.
• Turn off the hot water taps and the heater will automatically turn itself off.
• When one or more hot water taps are turned on the heater will automatically maintain
the heater’s pre-set outlet hot water temperature.
USEFUL INFORMATION ABOUT THE HEATER’S OPERATION.
• If a hot tap is set to a very low water flow the heater may not light or may automatically
turn off causing the water to go cold. If this occurs opening the tap to increase flow will
allow the heater to operate normally.
• To quickly attain and/or maintain the pre-set outlet temperature the heater may
automatically vary or limit the flow. The heater will only do this if too high a flow rate has
been selected or the mains supply is very cold. On any start up at high flow rates this will
become apparent and heater will limit flow until water is hot enough. This limits energy
wastage.
• On colder days steam may be seen coming out of the flue outlet. This is normal for a gas
water heater.
• The heater will not operate if the electrical power supply is interrupted. Once power is
restored the heater will operate normally.
• The fan in the heater will continue to run for a short time after all hot taps have been
turned off. This is normal. The heater is preparing itself for the next time it has to heat
water.
• The drain plug on the heater’s hot water outlet is also a pressure relief valve. A small
amount of water may drain from the pressure relief valve if a hot water tap or a solenoid
water valve in an appliance is closed quickly.
FROST PROTECTION
Provided your heater is connected to a reliable 240V electrical supply it is automatically
protected against damaging due to freezing.
If freezing conditions are likely and the electrical power supply is unreliable the heater should
be drained of water.
See section in Operating Instructions headed How to Drain Heater for Frost Protection

IMPORTANT INFORMATION FOR SAFE OPERATION
• Hot water can cause a severe scalding injury.
Those most at risk are children, the elderly the infirm and anyone with disabilities.
We recommend and plumbing regulations may require that that the temperature of the hot
water delivered to rooms such as your bathroom and en-suite is limited to 50ºC. This will
reduce the risk of scalding injuries.
If you have not previously had a 50ºC limited supply to your bathroom or en-suite you may
find that it takes a little longer for hot water to arrive at the tap. This is normal and indicates
the reduced scalding risk a 50ºC supply provides.
It is the installing plumber’s responsibility to ensure the water delivered to your hot taps is at
a temperature which complies with all relevant regulations. However we recommend that you
inform yourself of all your hot water taps’ delivery temperatures.
In order to lower the hot water delivery temperatures to your bathroom and en-suite or any
other taps to a maximum of 50ºC an approved temperature limiting device will be required to
be fitted to your pipe work.
RAPID R26N and R26P are designed for installation as in series solar boost heaters
and are required by plumbing regulations and can be set to have a minimum pre-set
delivery temperature of 70ºC MIN.
Water heated by the solar heater to temperatures in excess of 70ºC may pass through the
heater and be delivered to your hot water taps.
In order to lower the hot water temperature to your bathroom and en-suite or any other taps
to a maximum of 50ºC an approved temperature limiting device will be required to be fitted to
your pipework.
• There is a hot gas flame inside your heater when it is operating
Keep flammable materials, spray cans, fuel containers, chemicals, trees and shrubs
etc. well clear of the heater.
• The discharge from the heater’s flue outlet is hot.
Do not touch the heater or outlet.
Do not insert anything into the flue outlet.
Do not spray water directly into the flue outlet.

HOW TO DRAIN HEATER FOR FROST PROTECTION
1. Turn off gas and cold water supply at the isolation valves under heater.
2. Turn off electricity at the power outlet the heater is plugged into.
3. Turn on a hot water tap. Preferably the shower.
4. Remove the drain plug from both the hot water outlet and the cold water inlet at the
bottom of the heater.
5. Allow all water to drain from heater. Turn off hot water tap when the water flow stops.
6. Store drain plugs in a safe place.
How to Re-start heater after freezing conditions have passed
1. Re-fit and tighten both drain plugs so they seal.
2. Turn on the cold water supply at the isolation valves under heater.
3. Turn on all hot water taps and allow the air in the pipes to be forced out.
4. Turn off each hot water tap once it flows normally
5. Turn on electricity at the power outlet the heater is plugged into.
6. Turn on gas isolation valve.
The heater will now be ready for normal use.

TROUBLESHOOTING
No water flow from hot tap
Check that both the house mains supply at the water meter and the cold water isolation valve
at the heater are fully open. If the mains supply tap is open water should flow from cold taps
in the house.
Cold water from hot water taps
Increase flow and see if water begins to heat. Remember heater will NOT heat if tap only
permits a very small flow.
Turn off hot tap. Wait 5 seconds and then try again with a strong flow.
Check that electricity and gas are turned on at heater.
You can check if electricity and gas are turned on at their meters by turning on other
appliances in the house that are connected to electricity or gas.
Hot water flow varies
The heater is designed to deliver water at a fixed temperature. If you attempt to draw more
hot water than the heater can provide e.g. by turning on too many taps, the heater will limit
the flow.
Hence when say 3 or 4 taps are turned on strongly and the flow is beyond the heater’s
capacity to heat, the flow from the taps may be reduced but the temperature will be
maintained.
If you have not found a solution to the problem.
Contact Alliance Service Department for further information and a service call if required.
This heater must be serviced only by an authorised person

WARRANTY
Alliance continuous flow gas water heaters models R26N, R26P
WATER SUPPLY QUALITY
This water heater must be connected to water of a quality within the limits described
below to be covered by the warranty.
This water heater is manufactured to suit the water conditions of most public reticulated
water supplies. However, there are some known water chemistries which can have
detrimental effects on the water heater and its operation and / or life expectancy. If you are
unsure of your water chemistry, you may be able to obtain information from your local water
supply authority.
CHANGE OF WATER SUPPLY
The changing or alternating from one water supply to another can have a detrimental effect
on the operation and / or life expectation of a heat exchanger in a continuous flow water
heater.
Where there is a changeover from one water supply to another, e.g. a rainwater tank supply,
bore water supply, desalinated water supply, public reticulated water supply or water brought
in from another supply, then water chemistry information should be sought from the supplier
or it should be tested to ensure the water supply meets the requirements given in these
guidelines for warranty to apply.
SATURATION INDEX
The saturation index (SI) is used as a measure of water’s corrosive or scaling properties.
In a corrosive water supply, the water can attack copper parts and cause them to fail.
Where the saturation index is less than –1.0, the water is very corrosive and warranty does
not apply to a copper heat exchanger in a continuous flow water heater.
In a scaling water supply calcium carbonate is deposited out of the water onto any hot
metallic surface. Where the saturation index exceeds +0.80, warranty does not apply to a
copper heat exchanger in a continuous flow water heater.
Water which is scaling may be treated with a water softening device to reduce the saturation
index of the water.
WARRANTY CONDITIONS
1. The water heater must be installed in accordance with the water heater installation
instructions, supplied with the water heater, and in accordance with all relevant statutory
and local requirements of the State in which the water heater is installed.

2. Where a failed component, heat exchanger or water heater is replaced under warranty,
the balance of the original warranty period will remain effective. The replaced component,
heat exchanger or water heater does not carry a new warranty.
3. Where the water heater is installed outside the boundaries of a metropolitan area as
defined by Alliance or further than 25km from an Alliance Accredited Service Agent, the
cost of transport, insurance and travelling costs between the nearest Alliance Accredited
Service Agent’s premises and the installed site shall be the owner’s responsibility.
4. Where the water heater is installed in a position that does not allow safe, ready access,
the cost of accessing the site safely, including the cost of additional materials handling and
/ or safety equipment, shall be the owner’s responsibility.
5. The warranty only applies to the water heater and original or genuine (company)
component replacement parts and therefore does not cover any plumbing or electrical
parts supplied by the installer and not an integral part of the water heater, e.g. pressure
limiting valve; isolation valves; non-return valves; electrical switches; pumps or fuse.
6. The water heater must be sized to supply the hot water demand in accordance with the
guidelines in the water heater literature.

HEATER LOCATION
• The heater should be installed as close as practicable to the most frequently used hot
water tap.
• The heater must be fixed to a vertical structure e.g. a wall using the screws and fixing
points provided. The wall may have timber cladding.
(Alternative fixing screws may be used if they are more suitable for the mounting surface.)
• The installation location must provide adequate clearance for servicing and permit the data
on the rating plate to be easily read.
• The heater must be able to be serviced without having to stand on a ladder.
• The heater incorporates a frost protection system which will protect the heater provided
that a 240V supply is connected to the heater. If the heater is to be left unattended for any
length of time in very cold weather it should be drained of water to ensure frost protection.
See section in Operating Instructions headed HOW TO DRAIN HEATER FOR FROST
PROTECTION
Recessed Installation
The heater can be installed recessed into a wall with a Wall Recess Box Kit.
The Wall Recess Box kit contains the instructions for this type of installation.
• The flue terminal must be positioned so that flue products do not enter a dwelling and so
that the operation of the heater is not affected by anything too close to the flue outlet e.g.
fences or shrubs.
See a current issue of AS/NZS 5601 for the full set of rules governing the location of
the flue terminal.
For example. Some of the requirements of AS/NZS 5601 are:
The flue terminal must be positioned so that there is AT LEAST
> 300mm between
• the top of the flue terminal and the eaves
• the flue terminal and a return wall or external corner measured horizontally along the
wall.
> 500mm between
• The flue terminal and the edge of any opening into the building measured horizontally
along the wall
• the flue terminal and a fence, wall or other obstruction in the flue discharge path
> 1500mm between
• the top of the flue terminal and the closest part of any openable window above the
terminal.
• The flue terminal and any opening into a building which is in the direction of the flue
discharge.
