Presume these boilers are the same,both have same gc number 47-267-24.Problem is boiler cuts on /off every 15 secs on c/h and h/w,if I remove the high limit stat from pipe work boiler appears to stay on,I have swopped the c/h-h/w thermistors over and its still the same,also heard that the Venturi can cause this problem.After removing and replacing high limit stat a few times boiler now goes to lockout,if I short out high limit stat boiler works,also it does not appear to be overheating.Anyone come across this fault.
 
If you post your question on the Gas Safe forum I will tell you what the problem is and how to solve it.
