: : what should I do if my flue gas analysis shows both carbon monoxide and oxygen

: Most likely carbon monoxide and oxygen will be detected because combustion is never perfect, but note the amounts and attempt to reduce them without creating other combustion problems.

: Watch the CO concentration. Legally, you cannot vent flue gas with over 400 ppm CO. CO will be generated with either lack of combustion air or excess combustion air. If the O2 is high with the CO, look to reduce the combustion air or increase the fuel rate. If the O2 is low and the CO is high, increase the combustion air. You can watch your analyser as you increase or decrease the combustion air, and adjust to the lowest CO reading. Low fire will typically have a higher O2 content than high fire and the CO is usually lower on low fire than high fire. e-mail me and I wil be happy to get into more detail.
