16 Fault FindingBefore trying to operate the boiler make sure that :• All gas supply cocks are open and that the gas supply hasbeen purged of air.• The heating system pressure is at least 1 bar.• There is a permanent mains supply to the boiler and that thepolarity is correct.WARNING. Always isolate the boiler from the electrical supplybefore carrying out any electrical replacement work.Always check for gas soundness after any service work.Should there be any doubt about the voltage supply to any ofthe components, it is possible to carry out a simple electricaltest to ensure all is operational in that area.IMPORTANT: On completion of the fault finding task which hasrequired the breaking or remaking of the electrical connections,the continuity, polarity, short circuit and resistance to earthchecks must be repeated using a suitable multimeter.Overheat thermostat reset buttonRefer to Section 18.10 to locate the overheat thermostatreset button.Depress the button to reset.9749OVERHEATTHERMOSTATRESETBUTTONDiagram 16.14000124050-234
