that the appliance be checked and serviced as necessary at regular intervals.

Generally once per year will be sufficient. It is the law that any servicing must be

carried out by a competent person.

must be observed: Top : 127 mm, Bottom : 127 mm, Left : 1 mm, Right : 1 mm &

Front : 540 mm. Extended clearance is required to the front to allow for access

stubborn marks wipe with a damp cloth and finish with a dry cloth.

2) Switch on the electric supply to the boiler and controls and set the heating

controls to call for heat.
