8.Fault Diagnosis

If a fault develops, or is suspected, call your Service Engineer as soon as possible

Go through the following checklist before you make contact

Is the electricity supply on?

Are the lamps lit?

Has the limit thermostat tripped?

Are the boiler isolation valves open?

Are the pump isolation valves open?

Is the boiler switch on (giving a red “Power ON” light)?

Is the heating system water pressure correct?

Is the boiler temperature control set correctly?

Is the time clock (if fitted) calling for central heating?

Is the room thermostat (if fitted) set high enough?

Are the radiator valves open?
