Pre-Installation
NOTICE
Non-return valves in the cold water feed system.
If a non-return valve is fitted on the mains inlet, then pressure can
increase significantly over normal standing pressure when the appliance
carries out a DHW preheat or due to fast acting valves closing on other
appliances/outlets.
▶ To ensure water pressure stays at a level that will not damage the
boiler or other household appliances, we would recommend on
installations where standing pressure exceeds 3bar, that a 3 bar
pressure reducing valve and mini expansion vessel are fitted.
When handling static sensitive components, avoid
damage caused by static discharge by following Electro-
Static Discharge safety procedures.
• Where the mains water supply has a non-return, back flow prevention
valve fitted, a mini expansion vessel [3] should be connected to the
mains water inlet pipe [1] between the non-return valve [2] and the
appliance[4] as shown below.

Appliance location and clearances
4.3.1
Appliance location
• Follow local regulations for the location within the property that the
appliance is to be installed.
• This appliance is only suitable for installing internally within a
property at a suitable location onto a flat, fixed rigid surface capable
of supporting the appliance weight.
• The appliance is not suitable for external installation.
• Protect installation area against dust and moisture.
No surface protection is required against heat transfer from the
appliance.
DANGER
Danger from explosive and flammable materials:
Storage of explosive and flammable materials.
▶ Do not store flammable materials (paper, curtains, clothing, primer,
paint, ...) in proximity to the appliance.

WARNING
Risk of injury due to damage to the appliance
▶ The appliance must not be sited in such a position that some or all of
the underside of the appliance is closer than 760mm above a
permanently fixed hob.
▶ Reasonable care should be taken to ensure the appliance is not
installed directly above where other heat-producing kitchen
appliances such as portable hot plates, toasters and kettles are likely
to be sited.
NOTICE
Damage to appliance:
Contaminated combustion air.
▶ Do not use any cleaners containing chlorine or hydrogen halide (i.e.
spray cans, primers, cleaners, paint and glue).
▶ Do not store or use these substances in the appliance or room.
▶ Avoid the build-up of dust.
NOTICE
Damage to appliance:
Extreme temperatures may cause damage to the appliance.
▶ Ensure the appliance location's ambient temperature is above 0 °C
and below 50°C.
NOTICE
Damage to system:
The heating system pipe work can be damaged by frost if installed in an
internal unheated area, such as a loft, basement or garage.
The appliance internal frost protection only monitors the system water
temperature within the appliance to provide protection for the
appliance.
▶ System frost protection can be achieved when using either Worcester
weather-compensating controls or via a hard-wired thermostat when
using external 230 V controls (refer to figure 62, page 41).
▶ The system pipe work in the internal unheated area should be
insulated.
▶ If the appliance is to be shut down for an extended period, drain the
central heating system.
The appliance must be installed where:
▶ The area is well lit, allowing users to clearly see the appliance to carry
out any work or checks.
▶ An engineer can gain clear and safe access to work on the product or
component, including making adequate provision for visual
inspection of flues in voids.
▶ The homeowner can gain clear and safe access to the controls or to
check, top up or reset the appliance.
▶ Roof space installations must fully conform to BS 6798: roof space
installations.
▶ Products in roof spaces must have permanent fixed lighting, a
permanent fixed retractable ladder and a fixed floor area sufficient to
allow access for normal use and servicing around the product and
between the product and the access hatch.
We would also recommend that a remote pressure gauge and filling
loop are sited where the customer can gain easy access to assist with
checking and topping up.
