GENERAL INSTALLATION REQUIREMENTS

The cylinder must be installed, commissioned and maintained by a competent installer holding a current G3
unvented qualification, and/or being a member of a competent persons’ scheme. Once the unit is installed
and commissioned, the user must be given an explanation of the operation of the cylinder and its key safety
components. In addition, the end user must be given this installation manual for future reference.

STORAGE AND HANDLING

Care must be taken when handling the product. Seek assistance when moving the product as required, and
follow safe working practices and lifting techniques to avoid injury or product damage. Before installation,
the cylinder must be stored upright in its original packaging, on a secure, level surface within a dry and frost-
free environment.
2
SITING THE UNIT
This product must be installed vertically on a flat base that is capable of supporting the maximum-fill
weight of the cylinder. For each metre an outlet is above the cylinder, the supply pressure of the hot water
will be reduced by 0.1 bar.
The minimum recommended cupboard size is 650mm square as the product diameter can vary (capacity
and configuration dependant) between 475mm to 580mm. This is to ensure that there is access to the
cylinder safety controls/immersion heaters and for future valve maintenance or replacement during service.
Therefore, please ensure all connections are outward facing towards a door or similar opening for this
purpose.
Areas subject to freezing should be avoided. If the cylinder is sited outside of a heated area of the
dwelling, such as a garage or outbuilding, ensure the provision of adequate frost protection, such as insula-
tion of exposed pipework. Pipe lengths must be kept to a minimum to ensure minimal losses.

COLD WATER INLET CONTROL SET

Included in your unvented safety components is a multibloc inlet control group. This single unit is
standard issue for many unvented water systems, and comprises of many different safety valves, housed
into a single brass casting. This is detailed as follows:

3 Bar Pressure Reducing

Valve and line strainer Expansion Relief
(Discharges to Tundish)

Cold water supply to

Cold water mains in
Cylinder

3 Bar balanced Connection to

Cold Feed Expansion Vessel
WATER SUPPLY
We recommend that the maximum on-site water demand be assessed and the water supply be tested to
ensure it meets the following requirements.This should be sourced from mains water only - your warranty
does NOT include the use of wells or bore holes as a water supply.

It must be noted that a high mains water pressure does NOT always guarantee a high flow rate. Ensure a
working (not static) condition site pressure reading is taken. The minimum mains water supply requirements
should be 0.15MPa (1.5 bar) working pressure, and a 20 litres per minute flow rate available. Where mains
inlet pressures may exceed 10 bar, an additional upstream pressure reducing device should be fitted in addi-
tion to the cold water inlet set provided.
The mains supply pipe-work should be a minimum of 22mm. This could warrant the replacement of any
existing 1/2” (15mm) cold mains pipe-work.

The water supply must be of a wholesome water quality, defined as Fluid Category 1 in the Water Sup-
ply Regulations 1999. In areas of hard water content (CaCO3) greater than 200ppm, treatment should be
installed.
CHANGE OF WATER SUPPLY
The changing or alternation of one water supply to another can be detrimental on the operation and/or life
expectation of the product and its accessories. Where a water supply changeover occurs, 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, or should be tested to ensure the
supply will meet the requirements given in these guidelines for our manufacturer’s warranty to apply.

GENERAL INSTALLATION AND COMMISSIONING

PLEASE NOTE - THE WATER CONNECTION BOSSES AND THE OLIVES & GLAND NUTS SUPPLIED AS
STANDARD ON THIS INDIRECT ARE THREADED 3/4” BSP.
COLD MAINS PIPEWORK
The cold mains pipework should be a minimum of 22mm, through to the cylinder installation to ensure that
hot water flow requirements for taps and shower heads are met. Care should be taken to avoid
inefficiency and heat transfer where cold water pipes run adjacent to hot water or heating pipework.
Install an isolating valve (not supplied) to the cold mains pipework. A 22mm BS1010 stopcock or a
quarter turn full-bore lever valve should be used rather than a screwdriver slot or other similar valve.
Make the connection to the cold feed of the cylinder, incorporating a drain valve.

Position the inlet control set above the Temperature and Pressure Relief Valve (T&P) found on the side of the
cylinder. This ensures the cylinder does not need to be drained in order to service the inlet control. Ensure
the directional flow arrow on the inlet control follows the flow of water.
Mount the external expansion vessel in a suitable position to the wall using the provided bracket, and con-
nect the pipework to the expansion vessel connection provided on the cold water inlet set. There must be no
obstruction or flow restriction between the cylinder and the expansion vessel.
You must ensure that the cylinder does not fill to a pressure of greater than 3.0bar. If there are to be any
showers, bidets, or monobloc taps in the installation (or wherever mixing/blending water fittings are
installed) then a balanced cold supply is necessary, otherwise there is the danger of a mains fed cold service
pressure leaking into the controlled hot circuit. Such back pressure would be detrimental to the system and
could cause the unwarranted operation of discharge valves.
It is essential that the cold service be balanced throughout the property by taking the cold services from the
balanced cold connection on the inlet control set. Should this not be possible an independent 3.0bar inlet

4
pressure reducing valve must be installed into the cold supply of any such mixed fitting, suitably positioned
so as to not compromise water flow to the cylinder. An outside hose tap may still be connected direct to the
incoming cold supply if desired.
HOT WATER PIPEWORK
The majority of the hot water distribution pipework should be 22mm, possibly reduced to 15mm or 10mm
dependant on the type of tap. Keep the hot draw off pipework to a minimum to maximise the transfer speed
of hot water from cylinder to outlet. We advise against soldering fittings immediately to the hot water draw
off, as this reduces any inherent risk of flux landing on the immersion heater and causing premature corro-
sion to the connection and unit.

If the balanced cold connection is not provided, do not use monobloc mixer taps or showers. This would
cause the unit to back pressurise and result in discharge. Ensure that the top of the vessel is accessible for
servicing.
CONNECTION OF PRIMARY COILS - BOILER AND SOLAR (See Schematic on Page 8)
Both boiler and solar coils are provided with 22mm compression connections and are suitable for open
vented or sealed system primary circuits. The coil must be positively pumped and are not suitable for gravity
systems. To ensure maximum performance and efficiency the primary flow must enter the left hand lower
coil connection when viewed from the front of the cylinder, and return from the right hand upper coil
connection. An air release valve must be installed adjacent to the return connection point. The boiler coil
should also benefit from the operation bypass when the heating circuit closes. See diagram.
In twin coil installations this installation detail applies to both coils.
The coils are rated to 6.0 bar maximum operating pressure although heating circuits normally operate at
a maximum of 3.0 bar, solar circuits 6.0 bar. In a boiler circuit the two port valve should be installed in the
primary flow. In a solar circuit the two port valve should be installed in the primary return.
Ensure an inhibitor suitable for use with stainless steel is used. Only connect the cylinder to a protected heat
source with effective thermostatic control - uncontrolled heat sources such as solid fuel stoves, AGAs etc.
may not be suitable - if in doubt seek guidance from ourselves.
CONTROL THERMOSTAT
The non-solar indirect cylinders come provided with a mechanical control dual cylinder thermostat. This
adjustable safety component can be changed by the end user to keep the hot water in the cylinder stored
at any value between 25°C-65°C. As well as being a thermostatic control, the stat also functions as a heat
source isolation safety device with the included 2-port zone valve in the event of overheating, and should be
installed as per the wiring diagrams set out in this manual.

When the cylinder thermostat is set to maximum, please ensure that the flow output from the boiler is also
set appropriately so that the vessel can achieve the desired temperature.
RECOMMENDED STORAGE TEMPERATURE
For domestic usage a temperature set of 55°C-60°C is the norm. This is above recognised bacterial growth
levels and low enough to prevent nuisance tripping of limit thermostats or unnecessary scaling.
SOLAR COIL INSTALLATION
INDIRECT SOLAR SINGLE AND TWIN COIL MODELS
Indirect solar single coil cylinders have one coil at the bottom of the cylinder for connection to the the solar
thermal system. For indurect solar twin coil cylindersconnect only the lower coil to the solar thermal system.
Connectionprocedure to solar is identical for both products. Connect the solar coil as instructed in the above
section “CONNECTION OF PRIMARY COILS - BOILER AND SOLAR”. The solar temperature control sencor (sup-
plied as part of the solar package) inserts into the pocket directly above the coil and is retained with the wir-
ing grommet supplied. High limit control of the solar input is monitored with the single high limit thermostat
which inserts into an upper pocket at the the same height as the T&P relief valve. For installations where solar
panels are higher than the cylinder connect the stat to interrupt the electrical supply from the solar pump
and / or solar control panel. For installations where the solar panels are lower than the cylinder connect the
high limit thermostat to close a two-port valve (not supplied) installed on the solar return pipework. With
solar indirect twin coil the upper coil connects to the boiler flow and return. The dual control / high limit
thermostat installs into the pocket immediately above the upper coil and is wired to activate the two-port
valve (supplied) installed into the boiler primary flow.
This cylinder as supplied is not designed for installation with two boilers without extra controls listed below.
Should it be the desire to connect the solar indirect twin coil cylinder to two boilers then a further dual
control / high limit thermostat and two port-valve will be required and both coils and safety controls must
be installed as per the single coil boiler format. Both the additional thermostat and two port valve may be
purchased from the cylinder manufacturer.
5
SECONDARY CIRCULATION
Seconday return connections are supplied as standard on 200-300 litre indirect cylinders only. Where
secondary circulation is unavoidable for smaller capacity cylinders, a circulator suitable for potable water
must be used in conjunction with a non-return valve to prevent backflow. The return connection should be
made with a swept tee into the cold feed pipework directly above the drain connection. It may be necessary
to incorporate an extra expansion vessel into the circuit to accommodate an increased system volume in
larger secondary circulation systems.
IMMERSION HEATER
All standard supply is with immersion heater elements of 3 Kilowatt output at 240 Volts, Incoloy elements,
double pole thermal isolation and a 1¾” BSP threaded head.
ELECTRICAL CONNECTION - 3kW
This appliance must be earthed. It is suitable for a 240 volt A.C. supply only. The electrical installation should
only be carried out by a suitably qualified electrician in accordance with latest I.E.E. regulations. Ensure the
electrical supply is isolated before working on the system.

The electrical supply to each immersion heater must be fused at 13A via a double pole isolating switch with a
separation of at least 3mm to both poles to BS 3456.

The cable must be 2.5mm2 heat resistant (85°C HOFR) sheathed flex complying to BS EN 50525. Do not use a
cable of lesser rating.

For immersion heaters other than 3kW consult wiring requirements supplied with the immersion heater.

Do not operate the immersion heater(s) until the unit is full of water. If any sterilisation liquid is in the cylin-
der do not operate the immersion heater(s) as this will cause premature failure.

This device must be earthed.

Earth connection, (green & yellow), should be made firmly to the earth post marked “E”, using the
terminal attachments provided. Live connection, (brown), from the mains supply cable to the thermostat
terminal marked “L”. Neutral connection, (blue), from the mains supply cable to the thermostat terminal
marked “N”.
WIRING - 3kW
Our 3kW immersion heaters MUST be wired in 2.5mm2 heat resistant cable, as failure to do so can cause
nuisance tripping. We will be unable to support your installation until this has been corrected. For
alternate higher wattage immersion heaters, consult the instructions supplied with the device.
COMMERCIAL/HEAVY DUTY USE
For commercial/heavy duty installations with constant usage/reheat requirements or where an external
programmer designed for immersion heaters is not present then Titanium immersion heaters must be fitted
in order to comply with the warranty.
RECOMMENDED TEMPERATURE SETTINGS - IMMERSION HEATER
For domestic usage a temperature set of 55°C-60°C is the norm. This is above the growth temperature area
for Legionella and low enough to prevent nuisance tripping and unnecessary scaling.
THERMOSTAT OPERATION
The thermostat has an adjustable control operating between 20°C and 65°C. The usual desired domestic set-
ting is between 55°C and 60°C. The thermostat is supplied set at 60°C. For setting the stat, turn fully clockwise
to the maximum, and then anticlockwise (back off ) approximately a quarter of its travel. Then make minor
adjustments to suit your personal taste.
THERMAL CUTOUT
If the cylinder begins to overheat (80°C), the thermal cut-out will activate, isolating both the live and neg-
ative connections within the immersion heater. This may also happen during a power spike. For resetting,
isolate the power supply and allow the cylinder to cool down. Remove the head cap and press the high limit
cut-out reset button on top of the thermostat. Should nuisance tripping occur, consult a qualified electrician
to investigate the power supply and/or the thermostat itself.

6
REPLACEMENT IMMERSION HEATERS - ALL TYPES
Replacement immersion heaters are available in all formats for your water heater. These should be
obtained via ourselves to ensure the correct specification is supplied, and our warranty is not
compromised. The standard heater has incoloy elements, a 1¾” BSP threaded head and standard rating of
3kW at 240 volts. Check the label detail on the head before ordering, as alternative specifications are availa-
ble.
The ‘O’ ring on the head of the immersion heater should be correctly positioned and lubricated with a WRAS
approved silicon lubricant before fitting. Screw in by hand until almost sealed and then gently finish tighten-
ing as the ‘O’ rings will seal easily. Remake the wiring connection as per instructions
provided.
INSULATION OF THE TEMPERATURE & PRESSURE RELIEF VALVE
Components for insulating the T&P are supplied in order to retain heat and energy. Installation instructions
are provided with the insulation cover.
DISCHARGE ARRANGEMENT
The diagram opposite was taken directly from UK government Building Regulations Part G: 2016.
This information is not exhaustive. If in doubt, seek advice. Full details of Building Regulation G3, is
available from: www.planningportal.gov.uk
The discharge from both the temperature, and expansion relief valves can be joined together via a 15mm
end feed tee. Water should only be discharged when there is a fault with the system, and be visible at the
tundish. (Consider a safety device to alert those of impaired vision or mobility when this occurs.)

Discharge water must not be allowed to collect in the pipe-work but rather flow freely to the tundish. This
should be vertically mounted, in a visible location, in the same space as the cylinder, and fitted as close as
possible within 600mm of the safety device (the relief valves). The discharge pipework must be in accordance
with Part G3 of the Building Regulations. These are as follows:

• The discharge pipe (D2) from the Tundish should have a vertical section of pipe 300mm long below the
Tundish before any elbows or bends in the pipework.
• This pipe should then be installed with a continuous fall of at least 1 in 200 thereafter.
• The pipe must be at least one pipe size larger than the nominal outlet size of the safety device (unless its
total equivalent hydraulic resistance exceeds that of a straight pipe 9m long i.e. discharge pipes between
9m and 18m equivalent resistance length should be at least two sizes larger than the nominal outlet size of
the safety device, between 18 and 27m at least 3 times larger and so on.) Bends must be taken into account
in calculating the flow resistance. An alternative approach for sizing discharge pipes would be to follow the
BS 8558 Specification for the design installation, testing and maintenance of services supplying water for
domestic use within buildings and their curtilages.

Discharge pipework should terminate in a safe place where there is no danger to persons in the vicinity of
the discharge. Examples of acceptable discharge arrangements include:
• To a trapped gully with the outlet below a fixed grating and above a water seal.
• Downward discharges to low level, within 100mm, above external surfaces such as a car park, hard stand-
ing, grassed area with a protective wire cage to prevent contact but retaining visibility of discharge.
• Into a metal hopper at high level with a metal downpipe and a clearly visible termination point or onto a
roof capable of withstanding high temperature discharge at least 3m away from any plastic guttering.

Building Regulation G3 allows non-metallic pipework within the tundish discharge (D2). The discharge pipe
(D2) should be made of a) metal or b) another material that has demonstrated it can safely withstand high
temperature water discharges and is clearly and permanently marked to identify the product and the perfor-
mance standard. The discharge should not be connected to a soil discharge stack unless it can be demon-
strated of safely withstanding high temperature water discharges, in which case it should;
1. Contain a mechanical seal, not a water trap, which allows water into the branch pipe but not foul drain air
to be ventilated through the tundish.
2. Be a separate branch pipe with no sanitary appliances connected to it.
3. Plastic pipes used as branch pipes with the discharge should be Polybutalene (PB) or cross linked
polythene (PEX) complying with national standards such as Class S of B7291-2: or Class S of BS7291-3
respectively.
4. Be continuously marked with a warning that no sanitary appliances should be connected to the pipe.
5. Plastic pipes should be joined and assembled with fittings appropriate to the circumstances in which they
are used as set out in BS EN ISO 1043-1.
Queries regarding specific discharge arrangements should be directed to your local building control office.

COMMISSIONING - FILLING THE SYSTEM
Check all connections for water tightness including factory made connections, as these may become loose in
transit. The expansion vessel should be 3 bar (45PSI).
The hot tap furthest away from the cylinder should be opened before filling the system to purge air and flush
any disturbed particles.
The pipes should be flushed before use. The remaining taps should be opened in turn to purge air from the
system before turning on the electrical supply.
SAFETY VALVE CHECKS
A problem is occurring if water is released from either safety valve during the heat up process (temperature
relief and expansion relief.) This must be rectified before continuing. Both valves should be opened slowly
one at a time, and then together, allowing as much water as possible through the tundish. Check that the
discharge pipework is cleared of obstruction, free flowing, and without spillage over the tundish. Check that
the valves reseat correctly when released.
DRAINING PROCESS
Isolate the unit from the electric supply to prevent immersion heater burn out. Isolate the unit from the cold
mains. Attach a hose to the draining tap. Ensure this reaches to a level below the unit for creating an effective
siphon so that the maximum amount of water is drained from the unit. Open the hot tap closest to the unit
and open the draining tap.

Caution: Water drained off may be hot.

SERVICE AND MAINTENANCE
• Servicing must be carried out annually by a competent installer.
• Any spares used must be purchased from us.
• Safety devices must not be bypassed. Do not use the unit if safety features are not
fully operational.
• Proof of annual servicing is required to avoid invalidating your manufacturer’s guar-
antee.
• Upon installation of the unit the installer must complete the accompanying
commissioning certificate at the rear of this manual.
ANNUAL SERVICING PROCESS
This must be conducted by a competent installer on an annual basis, ideally at the same time as the annual
boiler service:
1. The expansion relief valve should be eased open to allow water to flow for a minimum of 5 seconds. Close
the valve and make sure it resets correctly. Repeat this procedure with the temperature & pressure relief
valve. Ensure that the discharge pipework is cleared and allowing a free flow of discharge.
2. Ensure all fitted immersion heaters are working correctly. They should be controlling the water
temperature between 55°C and 60°C.
3. Make sure the pressure in the expansion vessel is set to 3 bar. This is done by turning off the water supply
to the unit and opening a hot tap first. Air or CO2 can be used for repressuring the expansion vessel.
4. Remove the head on the inlet control set and clean the mesh filter within.
5. Update the benchmark service record supplied after every service by the installer.
DISCHARGE AT THE TUNDISH
IF WATER IS FLOWING THROUGH THE TUNDISH THIS INDICATES DISCHARGE FROM ONE OF THE SAFETY
VALVES AND INDICATES A FAULT IN THE SYSTEM. CONTACT A COMPETENT PLUMBER OUT TO SERVICE
OR DIAGNOSE THE SYSTEM.

We will not cover any installer claims for excessive travelling where the installer has accepted a job
more than 30 miles from their base of operations.
Removal costs cannot be recovered for the collection of a faulty unit from a difficult to reach area or
where cylinder access has been restricted (as per this manual guidance.)
Claims will not be accepted for units that have not been installed in accordance with this manual.

When a problem arises, your first point of contact is the plumber who fitted the unit (in the first year), fol-
lowed by the plumber who carries out the annual servicing of your unit for you.
If your cylinder begins to leak, we will supply you with a new one. To prevent fraud, we request an up-front
payment in this case while we establish the cause of the fault.The original unit must be returned to us for
inspection along with a copy of your service record and commissioning checklist. Your upfront payment will
be refunded as soon as it is confirmed that the cylinder has failed within the terms of our warranty.
If a component part fails within the two-year guarantee, we will send you a new one with an upfront charge.
Your credit card details may be required to prevent fraud. We ask you to post the faulty part back to us by
recorded delivery within a month. A refund will be issued once the part has been tested and proven to be at
fault.
APPENDIX - WATER CHEMISTRY
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 cylinder. If you
are unsure of your water chemistry, you may be able to obtain the relevant water chemistry information from
your local water supply authority.
*Our warranty will not apply where water stored in the storage cylinder exceeds at any time any of the fol-
lowing levels: - TOTAL HARDNESS 200mg/L, TOTAL DISSOLVED SOLIDS 600mg/L
