get hold of corgis using portable flue gas analysers ,it will explain more but this will just give overall ratio so it must be under 0.0010 typically on se combis 23-24kw would give a correct reading between 0.0003 and 0.0005 30 kw will give between 0.0005 and 0.0007 but take a reading first,then carry out a service as all se appliances require then take a second reading they must be going to full rate a typical high reading would be gas pressures to high or before the service dirt
