    Hi,

    I serviced a Bosch Worcester 24Ri last week and also had to replace the PCB and the fan. When carrying out the gas flue analysis the reading was ridiculously high. CO/CO2 0.4216. Has anyone got an idea what might be causing this?

    Cheers, RobTheBuilder.

    Register for the combustion chamber. No answers for this will be given in the open forum.

    Yea, and if you don't then you should not be working on it.

    Yeah pretty much spot on Dan. :(

    The hole thing was stripped down and cleaned out. I just can't get my head round why it's like this.

    I don't know who installed and commissioned it originally as it was done in 2006, but I'm assured it was installed by a gas engineer.

    I'm just waiting for the combustion chamber to accept me.

    It's last service was 16/10/10. The cert says that the initial combustion analyser reading was 10.2% and the final was 9.8% but it didn't mention the ratio. My CO2 was 8%
