Instructions for Use

Boiler Clearances

If fixtures are positioned close to the boiler, space must be left as shown in diagram 3. Enough space must also be left in front of the boiler to allow for servicing.

Boilers Installed in a Compartment or Cupboard

If the boiler is installed in a cupboard or compartment do not obstruct any ventilation openings.

Do not use the cupboard or compartment for storage.

Regularly make sure that the air vent openings are clear of obstructions.

Cleaning

WARNING. This appliance contains metal parts (components) and care should be taken when handling and cleaning, with particular regard to edges.

Clean the casing occasionally by wiping it over with a damp soapy cloth or dry polishing duster.

Do not use an abrasive cleaner.

Protection Against Freezing

If the boiler is to be out of use for any long period of time during severe weather conditions we recommend that the whole of the system, including the boiler, be drained off to avoid the risk of freezing up. Make sure that, if fitted, the immersion heater in the cylinder is switched off.

If you have a sealed water system contact your installation/ servicing company as draining, refilling and pressurising must be carried out by a competent person.

Boiler Electrical Supply

WARNING. The boiler must be earthed.

The boiler must only be connected to a 240V~50Hz supply, protected by a 3A fuse.

All wiring must be in accordance with the current issue of BS7671.

The colours of three core flexible cable are:

Brown - live, Blue - neutral, green and yellow - earth.

As the markings on your plug may not correspond with these colours, continue as follows:

The wire coloured blue must be connected to the terminal marked “N” or “Black”.

The wire coloured brown must be connected to the terminal marked “R” or “Red”.

The wire coloured green and yellow must be connected to the

terminal marked “E”, “Green” or the earth symbol .

Electrical Supply Failure

Failure of the electrical supply will cause the burner to go out.

Should this happen, operation of the boiler will normally resume after the electrical supply is restored.

If the burner does not relight after an electrical supply failure the overheat device may need resetting, press the reset button on the underside of the boiler, see diagram 2.
