GENERAL

INFORMATION

ELECTRICAL CONNECTION

A mains cable should be connected to a double pole isolator with a contact separation of 3 mm on all poles and supplying the appliance and controls only.

The mains supply for your Danesmoor FS boiler is 230 volts

AC-50Hz.

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

FLUE OPTIONS

The Danesmoor FS may be installed onto a Conventional open flue or a factory made Room sealed balanced flue, the decision is made by the installing engineer and is dictated mainly by boiler location.

OPEN-FLUED BOILERS

Your installer will create airways (in walls or doors) to ensure an adequate supply of fresh air to the boiler for combustion. Do not block these airways, and never hang clothes or other combustible materials over the boiler or against the flue pipe.

Never place anything on top of the boiler.

ROOM-SEALED BALANCED FLUE

BOILERS

Air for this type of boiler is supplied via the balanced flue terminal, and no other air supply is required, except for ventilation if the boiler is installed in a cupboard or compartment.

ROUTINE MAINTENANCE

It is essential that your boiler is installed, commissioned and serviced by a competent heating engineer, and Worcester Heat

Systems will be pleased to arrange regular servicing and a comprehensive maintenance contract.

Alternatively OFTEC will gladly advise you of engineers trained by and registered with them.

Who are OFTEC?:

OFTEC are the Oil Fired Technical Association for the

Petroleum industry. OFTEC are recognised by the Government, its agencies, the major oil companies, oil distributors and manufacturers of heating appliances, equipment and oil storage tanks. For the domestic heating, oil distribution and commercial oil firing industry, OFTEC are the accepted trade body in terms of regulations, training and assessment. For the Oil industry, OFTEC registered technicians are the only people defined as ‘competent’ and able to self certify their work without the need to inform the local building control department.

They can be contacted at: Oil Fired Technical Association,

Foxwood House, Dobbs lane, Kesgrave, Ipswich, IP5 2QQ. Tel.

0845 658 5080 or: www.oftec.org

Servicing should be carried out at least once a year for boilers which burn 28-second kerosene, and twice a year for boilers which burn 35-second gas oil.

FUEL

Your Danesmoor FS boiler is factory set to burn

28-second Kerosene fuel. This fuel is permitted for use with a Conventional flue or Room sealed balanced flue arrangements across all output ranges.

35-second Gas Oil can only be used on conventional flue appliances which discharge at more than 2 metres above ground level. Both the

12/18 and 18/25 may be used in conjunction with

Gas Oil on Conventional flue arrangements, however the 12/18 model may only be used with

Gas Oil when commissioned to outputs of 15kW and above. Advice should be sought from the commissioning or Service engineer.

Conventional flue appliances which burn 35 second Gas Oil should terminate at a height of 2 metres or greater from the outside ground level.

Room sealed balanced flue appliances must not be used in conjunction with 35 second Gas Oil.

DATA

LABEL

LOCATION

SERIAL NUMBER

Your boiler serial number and model number should always be quoted in any contact with

Worcester Heat Systems. This will help identify your boiler accurately avoiding confusion and delays when placing a service call or ordering spare parts.

The boiler serial number and model number are printed on a data label which is located behind the front white panel as shown in Fig. 1. To access this data label you must remove the front white panel, as shown in Fig. 4.

For Service Engineers there is a more comprehensive data label on top of the appliances control box underneath the top white panel. Please make reference to the Installation and Servicing manual to gain access.

HOW TO START YOUR

BOILER

(See Fig. 2.)

(a) Turn on oil supply.

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

(c) Ensure that any external controls connected to the boiler, such as a room thermostat, are on a high setting.

(d) Set the programmer to the correct time of day and position the selectors to ON. The demand lamp in the control fascia will light up.

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

Fig. 3: 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 for a period shutdown.

6

TEMPERATURE CONTROL

The temperature control knob gives you control over the water temperature in your central heating radiators, and you can adjust it to any position within the indicated range (as shown in Fig. 3).

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.

The control knob has a range of adjustment as indicated by the numbers

OPERATING YOUR FASCIA

MOUNTED PROGRAMMER

CONTROLS

A fascia mounted programmer is available and replaces the small square blanking plate within the boiler fascia panel. Full instructions on how to install and operate this optional programmer are included in the programmer kit.

TROUBLESHOOTING

LOCKOUT

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 the red lockout light illuminating on the fascia, as shown in Fig. 2.

To cancel the burner lockout condition, remove the boiler front cover, as shown in Fig. 4. and press the lockout reset button, which is mounted on the under side of the boiler fascia, indicated as button ‘A’ in Fig. 5. 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.

TEMPERATURE SAFETY

Your boiler is fitted with two safety thermostats which are designed to protect your system in the event of the boiler running beyond a normal temperature level due to a control malfunction.

AUTO RESET THERMOSTAT

This thermostat will turn the boiler off and the demand indicator will go out if an excessive operating temperature is reached. This thermostat will reset automatically once the appliance has cooled down. If this thermostat persistently operates then please contact your service engineer.

MANUAL RESET THERMOSTAT

This thermostat will stop the appliance in the same manner as the auto reset thermostat above, but operates at a higher temperature and will not reset automatically. This thermostat has a reset button located on the under side of the boiler fascia, indicated as button ‘B’ in Fig. 5. To remove the front white panel see Fig. 4. If this thermostat persistanly operates then please contact your service engineer.

FAULTS & BREAKDOWNS

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 fault finder is included on page 10.

If, after checking through the points suggested, there is still a fault you should call your installer, service engineer or local

Worcester Heat Systems Service Centre. Arrangements will be made for an engineer to call as soon as possible.

CALL-OUT CHARGES

All of Worcester Heat Systems’ field service engineers are factory trained.

If you request a visit from an engineer and your boiler has been installed within the last 24 months, no charge will be made for parts and/or labour providing:

● The appliance was commissioned correctly on installation and a completed Guarantee Registration Card returned to

Worcester Heat Systems.

● An appliance fault is found and the appliance has been installed within the past 24 months, provided that the first annual service has been carried out on a boiler which is more than 12 months old. Reasonable evidence of this must be supplied on request.

A call out charge will be made where:

● The appliance has been installed for over 24 months

● The appliance has been installed for more than 1 year but less than 2 years and has not had a first annual service by an approved company.

OR

● Our Field Service Engineer finds no fault with the appliance

(see note).

OR

● The cause of breakdown is misuse or with other parts of your plumbing/heating system, or with equipment not supplied by

Worcester.

NOTE: Invoices for attendance and/or repair work carried out on your Worcester Danesmoor boiler by any third party will not be accepted.
