    I know I am getting too much combustion air. I don't know why. Just thought someone may have run across this situation before.

    Not on a Trane. Combustion air flow is controlled by the holes in the plate where the pipe comes from the gas valve.

    What test leads you believe that you are getting too much combustion air?

    Without a combustion test how can we help you? Check gas pressure inlet and outlet verify what nameplate calls for. The analzyer will give you o2, co,co2, efficency as well other things depending on model. Get back to us with those numbers and someone should be able to give you a place to start.
