3.0 INSTALLATION
Warning: This appliance must be earthed. It is suitable for a.c. supply only.
Electrical installation must be carried out by a competent electrician and be
in accordance with the latest IEE wiring regulation.
3.1 LOCATION
3.1.1 National Wiring rules may contain restrictions concerning the
installation of these units in bathrooms.
3.1.2 The unit should be located in close proximity to its outlet in order to
minimise heat losses in the pipework. The unit should be wall-mounted,
using the xing hooks and plugs supplied. The wall xing hooks should
be orientated such that the lugs engage with the mounting slots in the
rear of the unit (see Figure 01, page 3 for mounting hole dimensions).
The water connections must always be to the top of the unit. Ensure
the wall can support the full weight of the unit (see Section 2, p.3) and
that wall hooks are securely xed.
3.1.3 Enough space should be left above the unit for pipe connections and
access to the Pressure Relief Valve (see Figure 01, page 3 for unit
dimensions to determine a suitable position for the heater).
3.1.4 Ensure that there are no hidden services (electricity, gas or water) below
the surface of the wall.
3.1.5 DO NOT install where the unit may freeze.
3.2 PLUMBING
3.2.1 The water connections are for 15mm diameter copper tubes suitable
for compression ttings. Do not use solder joints as this will damage
the heater and may prevent servicing.
3.2.2 The electrolytic connectors supplied are tted between the inlet/outlet
threaded pipe ends and the 15mm compression ttings attached to the
supply/outlet pipework to prevent galvanic corrosion.
3.2.3 The INLET is marked BLUE, the OUTLET is marked RED. A WRAS
listed isolating valve (not supplied) should be tted on the cold water
supply to the heater. Several hot outlets can be served.
3.2.4 Plumbers Paste must not be used as it can impair the operation of the
valves.
5
3.3 IMPORTANT INSTALLATION POINTS
3.3.1 This unvented water heater MUST be tted with the Pressure Relief
Valve supplied. FAILURE TO PROVIDE ADEQUATE PRESSURE
RELIEF WILL INVALIDATE ANY GUARANTEE AND LEAD TO A
DANGEROUS INSTALLATION.
3.3.2 Expansion can take place within the cold water supply PROVIDED
THAT BOTH:
(a) Backow in the main is not prevented by any stop valve with loose
jumper, check valve, pressure reducing valve or similar AND;
(b) Hot water expansion does not enter a branch to a cold water outlet
(see Figure 02, page 6 for expansion pipe lengths).
N.b. Both the above conditions must be met. Additionally expansion
within the cold water supply will not be possible if the static supply
pressure exceeds 0.41 MPa (4.1bar).
3.3.3 If any of the conditions in 3.3.2 cannot be met, expansion must be
accommodated using an Expansion Vessel. To ensure all expansion
takes place in the vessel, a check valve must also be tted together
with the Pressure Relief Valve supplied (see Figure 03, page 6).
3.3.4 If the static supply pressure exceeds 0.41 MPa (4.1 bar), a Pressure
Reducing Valve must be tted to the cold main supply. If a Pressure
Reducing Valve is used, an Expansion Vessel must also be used (see
Figure 04, page 6).
3.3.5 The installation must be carried out in accordance with the relevant
requirements of:
• The appropriate Building Regulations either The Building
Regulations, The Building Regulations (Scotland) or Building
Regulations (Northern Ireland).
• The Water Fittings Regulations or Water Byelaws in Scotland.
WARNING: IF WATER FLOWS FROM THE PRESSURE RELIEF VALVE,
THE ELECTRICITY SUPPLY MUST BE SWITCHED OFF IMMEDIATELY.
CONTACT A COMPETENT INSTALLER FOR UNVENTED WATER HEATERS
TO CHECK THE SYSTEM.

3.4 DISCHARGE
3.4.1 The discharge outlet from the Pressure (expansion) Relief Valve must
be connected to a discharge pipe. It is recommended that a tundish
be installed in the discharge pipe to give a visible indication that the
valves are operating.
3.4.2 The discharge pipe must fall continuously from the valve outlets and
be unobstructed and in a frost-free environment.
3.4.3 The pipe from the valves to the tundish should be 15mm o/dia
minimum. From the tundish to the point of discharge the pipe should
be 22mm o/dia minimum and have a resistance to ow equivalent to
9 metres of straight pipe. Long discharge pipe runs should have an
increased internal diameter.
3.4.4 The water may drip from the discharge pipe of the pressure relief
device and this pipe must be left open to the atmosphere. The pressure
relief device is to be operated regularly to remove lime scale deposits
and to verify that it is not blocked.
3.4.5 The pipe material should be capable of conveying water/steam at
100°C.
3.4.6 The nal discharge point should be in a safe, visible position.

3.5 ELECTRICAL
WARNING: This appliance must be earthed. It is suitable for a.c. supply only.
Disconnect the electrical supply before removing the terminal cover. Installation
must be in accordance with the current I.E.E. Wiring Regulations.
3.5.1 The unit is supplied tted with a 0.75m 3 core 1mm2 exible cable. The
electricity supply should be fused 13 Amp and be via a double pole
isolating switch with a contact separation of at least 3mm in both poles.
Refer to the schematic wiring diagram Figure 05 below.

4.0 COMMISSIONING
4.1 PLUMBING
4.1.1 Do not switch on the electrical supply until the unit has been lled with
water and checked for leaks.
4.1.2 Check that all installation, electrical and discharge pipe requirements
have been met.
4.1.3 Check that all water and electrical connections are tight.
4.1.4 Open a hot water tap, turn on mains water supply to the heater.
9
4.1.5 Allow unit to ll and leave hot tap running for a short while to purge any
air and ush out the pipework. Close the hot tap and check the system
for leaks.
4.1.6 Manually test the operation of the Pressure (expansion) Relief Valve.
Ensure water ows freely from the valve and through the discharge
pipes.
4.2 ELECTRICAL
4.2.1 Switch on the electrical supply. The indicator light will illuminate during
heating. When the set temperature is reached, the indicator light will
go out.
4.2.2 The set temperature can be adjusted by rotating the knob on the
front face of the unit. Rotate clockwise to increase temperature, anti-
clockwise to reduce temperature. Setting 2 on the temperature control
knob equates to a water temperature of approx 45°C.
