CO testing

CO should be 0 - 99ppm but lower is not necessarily better. Also must be stable and never rising even the slightest.

    CO testing

    Just wonted to see what all you have to say about co testing.
    What kind of reading should you see in flue 80% and 90%.
    At what reading do you something or what readings mean what. Wont to see if on the same page.
    Thanks for the input and think this will help a lot.

    equipment the set up procedures give you definite figures for O2, CO2 and CO which is great. I have found that depending on the equipment those figures are pretty close to what gives the maxixmum firing rate with very little combustion problems on the over all operation.

    On all equipment not just heating equipment CO testing should be done. Unvented heaters allow 200 PPM, gas ovens allow 800 PPM these are ANSI standards which are insane. I want both of those appliances below 25 to 35 PPM air free CO.
