Triangle Tube Strange Problem

in THE MAIN WALL
Fall servicing a TT PS 60, it wouldn't lite. Checked ignitor (new last year) along with the ignition wire, everything OK. Checked spark with a spark plug tester, great spark. By accident I restricted the air flow into the venturi and it lit. Thought that was odd. Checked propane press. 9"WC. Checked combustion the best I could get was CO2 was 10.1% and O2 3.1%, adjusting the screw didn't make big changes. I also checked the vent and air supply both clean. I can get it to operate normally if I put some tape over the intake tube to the venturi to partly block the air but, that ain't right. Any suggestions would be greatly appreciated. Thanks

    It still sounds like a fuel/air mix problem.

    Call tech. support at (856)228-8881.
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    is there a check for combustion check at some other speed, like you set it at low speed but also has a spec for high speed or something like that?

    An air leak or a bad valve will cause it to be correct under the condition that you set it but incorrect at any other operating point.

    I would suspect an issue with the venturi or burner. At O2 of 3.1% you are a little rich. Why it would ignite when you make it richer is a head scratcher.
    This is a good question for tech support.

    did you check the venturi and the pressure drop in fuel pressure at the point of ignition you shouldn't see more than a 1" drop
