every time i turn the heating on, it starts up fine but only runs for about 10 min`s then goes out but the pilot goes out too? i spent the other night re-lighting the boiler every 15 min`s because of this (and it was too cold not to!). the hot water works fine, it`s just the central heating. the fan was recently replaced and all worked well up till this week ??

either the fan hasnt been fitted correctly or you have a worn thermocouple or blocked pilot. If the combustion case isnt fitted correctly (esp on bottom r/h side) this can cause the pilot to lift away from the thermocouple causing the gas valve to cut the pilot and main burner
