    They are...

    On the money!

    Whoever did the work should be kept.

    Believe it or not, most guys don't leave the combustion tags on their work. Some, because they didn't do it; others, because they did it, but don't know why.

    One Small Adjustment

    I would give up some of that CO2 for a lower CO.. Why not Zero.

    Also what is the draft over the fire.. Weil McLanes are a little tight.

    CO2

    What the manufacture design. Should be posted on the boiler.Most pin type boiler require -.02.. All boilers are different.Some boiler are designed to run + pressure.

    The CO2 max on oil should be 13 percent,but on this state the boiler is running like a hot rod.I rarely reach that that number and only on brand new equitment.You want to throttle back any way for a safey margin.Air leaks in the boilers gas seals will drop the CO2 and stack temperature..

    Accepitable CO level is 50 ppm use to be 200ppm years ago..

    The numbers as Ken mentioned are near perfect..



    PS Being a grunt for 35 years I take posted readings with a grain of salt...
