Hello, You appear to have misunderstood what I was asking for. I tried to make it clear that I have not and will not attempt to open the boiler myself. Having had two GSR people who had no idea how to fix, it I thought someone on this forum may have seen this problem before. I would then be able to point them in the correct direction.
I may not be GSR but I spent my working life working on the instrumentation off shore that produces the gas we burn . John.
