OK so the other day we had our (old) combi gas boiler (Volkera Excell 80sp) serviced. The guy did the usual check with a combustion meter in the flue, and got with a higher-than-allowed CO reading. Apparently the inner flue has corroded allowing combustion products into the boiler air supply. The flue vents directly through the external wall (so not void)
He has disconnected the boiler and capped off the gas supply as apparently this is "immediately dangerous". My question is: Is this correct? Having looked at the GUISP document, example 10.6 "Failure to achieve satisfactory combustion readings when using an electronic portable combustion gas analyser:" for flued appliances is an "At Risk" level and not "immediately dangerous". (nothing has indicated that combustion products are leaking into the house).
I accept that it is an old boiler and it's high time it was replaced, but I dislike the idea that they might be labelling it as "dangerous" to pressure us into a new boiler. Can anyone please advise?
