To ensure efficient safe operation of the appliance it is necessary to carry out routine maintenance at regular intervals. The frequency of servicing will depend upon the particular installation conditions and the use to which the boiler is put, but, in general, once per year should be adequate. The following notes apply to the appliance but it should be remembered that attention must be also paid to the central heating and domestic hot water circuits with special attention to radiator valves, thermostats, clocks, leaking hot water taps etc. WARNING Before starting any servicing work, switch–off the electrical supply or disconnect the plug at the main isolating switch and socket (if a switch is used remove the fuse).

After any service on electrical components follow the instructions in the British Gas Multi Meter Book for preliminary electrical checks; in particular: earth continuity; polarity; resistance to earth. 5.2 Recommended routine maintenance The following procedures should be carried out at least once per year: 1 verify that the electrical connections, the flue pipework and the case are in good conditions; 2 inspect ventilation arrangements as explained in section 2.5 to ensure no alterations have been made since installation; 3 switch—off the electrical supply and remove the front panel of the case (section 6.2); 4 switch—on the electrical supply and run the boiler for few minutes in the d.h.w. mode; 5 check that the flame covers all the flame ports and is of alight blue colour.
