4 SYSTEM OPERATING PRESSURE
4.1 Check the water pressure (System boiler only)
The normal operating pressure is between 1 and 2 bar.
If the pressure needs to be constantly re-pressurized or the pressure is
constantly over the 2.5bar mark, called your installer or service
engineer.
Fig. 14
4.2 System pressure
The method of charging the system may vary depending upon the
installation. Your installer must show you where your charging link is
located, how to re-pressurize your system and the advise you of the
normal system pressure.
Maximum pressure of 3 bar, at the highest hot water temperature,
must not be exceeded (The Pressure Relief Valve discharges to protect
the system).
NOTICE: Risk of freezing. In summer mode only the frost
protection devices are active..

5 FAULT OR BREAKDOWN
This boiler is supported in the UK and Eire by Worcester, Bosch Group.
Specialist Service Engineers are available to attend a breakdown
occurring on this boiler.
• No charge will be made for parts and/or labour providing:
A boiler fault is found and the appliance has been installed within the
last 24 months. Reasonable evidence of this must be supplied on
request. i.e. the Benchmark Checklist.
• A call-out charge will be made where:
– The boiler has been installed for over 24 months.
– Evidence cannot be provided that the first year service inspection
has been carried out.
– Our Field Service Engineer finds no fault with the boiler.
– The cause of breakdown is misuse or with other parts of your
plumbing/heating system, or with equipment not supplied by
your appliance manufacturer.

7 TIPS ON ENERGY SAVING
HEATING ECONOMICALLY
The boiler provides a high level of comfort whilst keeping gas
consumption and the environment effects as low as possible.
The gas supply to the burner is controlled according to the level of
demand for heat. The boiler operates with a low flame if the demand for
heat reduces. The technical term for this process is modulating control.
Modulating control reduces temperature fluctuations and provides an
even distribution of heat throughout the home. This means that the
boiler may stay on for relatively long periods of time but will use less gas
than a boiler that continually switches on and off.
CENTRAL HEATING SYSTEMS WITH ROOM THERMOSTAT/
THERMOSTATIC RADIATOR VALVES
With modern heating systems set around a 20 °C heat loss, the optimum
setting for a condensing boiler will be approximately between the first
and second segment on the central heating temperature control. The
system must be balanced correctly and the radiators may need
upgrading. This allows the boiler to condense as much as possible for the
central heating system.
The temperature of each room can be set individually (except primary
room with the room thermostat) using the thermostatic radiator valves.
ROOM THERMOSTATS
Reducing the setting of the room thermostat by 1 °C can reduce fuel
consumption by up to 10%.
NEW CONTROL SYSTEMS
Upgrade your heating control system if necessary with the latest
equipment available.
ROOF INSULATION
Around 30% of the heat loss from a property is through the roof. Replace
any old insulation with new insulation, preferably of around 200mm
thickness or more.
WINDOW FRAMES
Single glazed windows, particularly those with steel frames, can lose a
great deal of heat. Consideration should be given to replacement with
PVCu or wooden framed double glazed units.
RADIATORs
If a radiator is sited underneath a window, its performance will be
affected if the curtains are allowed to drape over the radiator. Shelves
fitted above or in front of the radiator should also be avoided.
It is advisable to manually adjust all thermostatic radiator valves
every 2 - 3 months to prevent them sticking.
Ensure radiator valves are correctly set and not damaged.
DRAUGHTS
Try to ensure that draughts around doors, windows, letterboxes and
keyholes etc. are reduced by using a suitable draught excluder.
CURTAINS
Lined curtains, or heavier full length curtains can provide excellent
insulation. However, always ensure that the curtains do not drape over
radiators.
Invoices for attendance and repair work carried out on
this boiler by any third party will not be accepted.
No boiler fault is found on over 30% of all service
calls.
In the case of a suspected fault, refer to the fault finding
section of this guide.
USED APPLIANCES
▶ All gas boilers are 100% recycleable.
The various assemblies can be easily dismantled and
synthetic materials are marked accordingly.
Assemblies can be sorted by composition and passed
on for recycling.
WARNING: Air vents
▶ Do not block or seal any air vents that are installed to
ensure that the central heating boiler operates
safely.
