I'm getting some silly readings from the O/2 sensor,the log looks more like a seismograph.I have the sensor about 8 inches from the header pipe merge in the bend inward toward the "X" .
Monte said it's most likely in a turbulent location.The sensor is at the 9 o'clock position.

SO where IS the sweet spot to install the sensor??? runaway
