GENERAL

INFORMATION

To ensure you get the very best from your new Worcester oil

boiler, please read these notes and instructions carefully.

Discard the user instructions provided within the white boiler

casing of the boiler and only use the Outdoor Pack user

instructions and boiler customer care guide.

ELECTRICAL CONNECTION

The electrical supply to this appliance must satisfy the latest

edition IEE wiring regulations and any local regulations, which apply.

The mains supply to the boiler should be fed via a circuit

breaker including earth leakage protection.

The mains supply for your Worcester boiler is 230 volts

AC-50Hz.

Your boiler must be earthed and protected by a 5-amp fuse

to BS1362.

VENTILATION AND AIR SUPPLY

Air for the boiler is supplied via the flue terminal, and no

other air supply is required.

ROUTINE MAINTENANCE

It is essential that your boiler is installed and serviced by a

competent heating engineer, and Worcester Heat Systems will be

pleased to arrange regular servicing and a comprehensive

maintenance contract.

Servicing should be carried out at least once a year for boilers,

which burn 28-second kerosene.

The service engineer should have access to the property to

check for system faults and reset / replace electrical safety devices.

WARNING NOTE:

Your boiler is serviced and repaired externally. External

equipment operated at 230 volts should not be serviced or repaired

under adverse weather conditions.

WARNING NOTE:

The service socket has been designed for use by the service

engineer only and should not be used for connection to any other

electrical household products.

NOTE:

The Outdoor Pack is not load bearing; it only provides

weather proofing for the boiler inside.

SERIAL NUMBER:

In any contact with Worcester Heat Systems quote your

boiler serial number, model and that it is fitted within the Outdoor

Pack. This will help identify spare parts and also avoid confusion

and delays during any service call-out.

You will find the boiler serial number on the front of the control

facia as shown in fig.1. Access can be gained by removing the

Outdoor Pack front cover and white front panel of the boiler

casing. (See section ‘Accessing your boiler controls.’)

TECHNICAL INFORMATION:

The Worcester Danesmoor Utility oil-fired pressure-jet

boiler when fitted inside the Outdoor Pack provides both domestic

hot water and full central heating, with outputs ranging from

12kW to 32kW (41,000 to 109,000 Btu/h).

The Worcester Bosch oil-fired pressure-jet boiler when fitted

inside Outdoor Pack provides both domestic hot water and full

central heating, with outputs ranging from 51,000 to 109,000 Btu/h.

Domestic hot water must be supplied via a conventional

indirect hot-water system, utilising an indirect double-feed

cylinder.

WARNING NOTE:Completely isolate the appliance

from inside the property before accessing your boiler controls.

The temperature control knob, overheat reset button and

lockout reset button are all located behind the white front panel of

the boiler casing within the Outdoor Pack.

To remove the Outdoor Pack front cover, remove the padlock,

if fitted, unscrew the two fixings pulling out and upward to release

the front cover. Then remove the white front panel of the boiler

casing by pulling forwards at the bottom end to release the lower

ball studs and repeat the procedure at the top end to release the

upper ones. Take care not to pull the bottom end too far forwards

as this may damage the spring clips

ACCESSING YOUR BOILER

CONTROLS

(See Fig. 1.)

(a) Switch on the electrical mains supply to the boiler.

(b) Ensure that any external controls connected to the boiler, such

as a room thermostat, are on a high setting.

position the selectors to ON.

(d) Ensure the switch on the Outdoor control box is in the ‘run’

position.

(e) Turn the thermostat control knob to the desired position

(see Fig. 2: temperature control).

(f) Your boiler will now commence a start sequence, in which a

pre-ignition period of approximately 15 seconds is followed

by a supply of atomised oil being introduced into the

combustion chamber. Ignition then occurs, followed by a post-

ignition period of approximately 20 seconds.

(g) Your boiler is now in a steady run condition and will remain so

until the water temperature reaches the temperature set on the

control thermostat. At this point the burner will stop and the

boiler will shut down. The sequence will continue until the

boiler is programmed - either manually or by an automatic

programmer - for a period of shutdown.

Frost Thermostat

Outdoor Control Box

During normal operation your boiler can be switched off at

the programmer, where fitted. A frost thermostat is fitted as

standard to protect the boiler only in frost conditions. If there is a

possibility the central heating /hot water system may be exposed to

frost conditions, an additional frost thermostat should be fitted.

Consult your installer if you are unsure! The boiler should remain

connected to the mains power supply to enable the boiler to

operate in the event of a frost condition.

In the event you have to switch off your boiler for long

periods, turn off the mains electricity at the isolator switch within

the property and drain the boiler and heating system.

The temperature control knob gives you control over the

water temperature in your central heating radiators, and

can be adjusted to any position within the indicated range

(as shown in Fig. 2).

Higher settings obviously mean hotter radiators and

rooms will reach the required temperature quicker. The

ideal setting varies from property to property, and can only

be established by trial and error and experience: a setting

of medium to high should serve as a good initial guide.

PLEASE NOTE: The control knob must not be set

below the first indicating bar

Your boiler is fitted with two high limit thermostats to protect

the appliance in the event of a control or system malfunction. The

first overheat thermostat is designed to cut out at a lower

temperature than the manual reset overheat thermostat, and will

reset itself when the boiler cools to a safe operating level.

The manual reset thermostat will operate if the boiler reaches

an excessively high temperature. This will have to be reset by

LOCKOUT

pressing the button located underneath the control box. (See fig 1.)

If the overheat thermostat persistently cuts out then your

boiler requires attention and you should call either your installer or

a service engineer.

A frost thermostat is fitted as standard to protect the boiler

only in frost conditions. If there is a possibility the central heating

/hot water system may be exposed to frost conditions, an additional

frost thermostat should be fitted. The boiler should remain

connected to the mains power supply to enable the boiler to

operate in the event of a frost condition.

A flame failure device is incorporated into the control system of

your boiler. So, should the flame fail for any reason, or should

ignition fail to initiate a satisfactory start, the boiler is automatically

locked out for safety. This lockout condition is indicated by a signal

lamp, located on the burner control box.

To reset the burner lockout condition, remove the Outdoor

Pack front cover and boiler front cover (See section “Accessing your

boiler controls”) and allow two minutes before pressing the

illuminated lockout reset button, which is mounted on the burner

control box. Provided the system is still calling for heat, the burner

will then operate and commence another start cycle.

Persistent lockout indicates a fault and an engineer should be

called, so do not attempt to repeatedly restart the boiler.

Your Worcester Danesmoor or Worcester Bosch pressure-jet boiler

is set to burn 28-second kerosene fuel.

PLEASE NOTE: This appliance must not be used with 35-

second gas oil.

Many calls made to Worcester Heat Systems to report boiler

faults or breakdowns prove to be false alarms, as there is often a

simple explanation for the apparent malfunction.

So, to help you save time and money - not to mention

frustration and inconvenience - a quick-reference faultfinder is

included on page 8.
