My other thought was whether the gas/air ratio is correct.
I had a neighbour install the boiler for me for £300. He's a fully qualified corgi plumber but can't imagine he would have had a worcester bosch manometer and done a full check.
Is this theory a case of 'A little knowledge is a dangerous thing'?
