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.

Technical Support

In the event of a boiler fault or breakdown please use the contact

numbers on the back of this manual.

Your advisor will arrange for an engineer to call with the minimum of

delay; under normal circumstances this will be from 1 - 3 working days

(excluding weekends) for priority breakdown situations (no hot water

and/or heating).

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.
