i have the above gas boiler installed in 2006, no problems till about 2 year ago when it started to lock out on the odd occasion, noticably more in the winter months it has now got to th stage of only lasting approx 15mins before it displays the overheat lockout lights and shuts off The gas engineer has recently replaced the combustion chamber with new seal and more resently the two stats on flow pipe but the problem still persist, any advice on how to rectify this would be much appreciated
