just moved boiler from one wall to the other, fired it up, runs for about 1min max then makes a "booming" noise as rthe gas ignites? took off front cover and galvanised cover behind, re tsart no noises but cycles on & off evry minute or so, works better if hot tap is not fully open. Been standing for about 6 weeks whilst new wall built, any thoughts more than appreciated

could be anything really but unless you are An RGI you shouldnt be mucking around with it.

If you are an RGI register with the combustion chamber and I am sure the lads will get stuck in for you

Will get slated as you shouldnt have done it if not registered but it is an air gas problem if no problem when combustion cover off.
will tell you how to fix it in combustion chamber as we shouldnt give out gas fixes to non gas installers
