I just had my ulrich wandich gas boiler serviced yesterday by a RGI, as i service and repair oil boilers myself i have a sprint v2 flue gas analyser so after he serviced my boiler i put my analyser in to check how well she was burning, The CO when shooting up to 350ppm and my analyser started beeping high levels of CO ventilate area, as i know gas boilers can be running grand having CO levels up to 200ppm plus depending on manufacture spec, but surely this cannot be right can it? or can it have CO levels this high and be within spec? Should i ring his boss and tell him to get his arse back over here.
