Converted new furnace to propane - red springs, #55 orifice. Pressures 12.5 WC in, 6 WC low stage, 10 WC high. Took 5 turns from initial 1.5 turns to set regulator. Is this a lot? Yellow flame even with vent and flew disconnected and door open. A lot of condensation to point that there is water in induction motor. Very little air coming out of top of furnace when vent was disconnected. I assume yellow flame is from air restriction. Is excess water from poor burn or poor burn somehow result of condensation drainage? There is only a 3/4 inch hole from heat exchanger to induction motor. Is this the correct size? Seems small. Can I damage furnace using it once a day to heat house? Thank-you for the help.
The problem is too much gas as opposed to not enough air. It is still running rich. Did you take into account the elevation of the location your furnace is installed at. The higher above sea level the less air that you have to aid in cumbustion. The condensation is from excess gas being cold and causing water to accumulate. Can you run it like this? Yes but it will cause issues with soot and carbon deposits. It will also cost you more money in the long run.
