hi i have an old thorne olympic boiler..i have changed the thermocouple and the pilot light stays alight...but when the main burner comes on the whole flame goes out as well as the pilot light after 5-10 mins. i have the thermostat set on 3..i have an independent timer that is set only for hot water at the moment...please can anyone help....
The boiler lights ok and begins to heat the water...
After 5 - 10 minutes burner and pilot extinguish...
1) Has the water reached the required temperature?
1a) Is there a "stat" on the hot water tank and what is it set to?
2) What do you have to do to get it to run again?
3) Does the pilot usually stay on when the hot water is "satisfied"
A skilled and experienced person might have an answer for you but being unskilled, inexperienced and consequentially, potentially dangerous - I'm not clear about the actual problem.
My boiler keeps going out (burner & pilot) after it's heated the water - then the water cools and the boiler automatically lights up again. It stays on for 5-10 mins while it's heating the water and stays off for a longer period. It does this until the timer programmer says stop.

Is the Flue blocked, or the Burner Gas Pressure too high?
Both these things should be checked by a Gas Safe Register Licensed Engineer
