The Fieldpiece SOX3 Combustion Checker with Auto Pump is a great tool to easily tune furnaces when a complete combustion analysis isn’t necessary—designed specifically for HVACR pros. The SOX3 provides all the essential measurements needed to adjust most combustion equipment. It measures %O2 and flue temperature and calculates %CO2, %Excess Air, and combustion efficiency.
The SOX3 Fieldpiece Combustion Analyzer tool was designed to help HVACR professionals do more with their devices. From custom fuels to field-replaceable O2 sensors. The SOX3 can be trusted to measure up for any furnace tuning job. Also, the pump works automatically. There’s no hand pumping, and techs can pause the pump anytime to save battery life. Furthermore, the SOX3 Oxygen Sensor indicators tell techs when a new sensor is needed. Moreover, with calibration data stored on the sensor, it can be swapped out in seconds (field-replaceable), so you never need to send your instrument in for calibration. The threaded R-cone holds the barrel firmly in the flue.
The strong magnet on the back of the SOX3 holds the device firmly to the side of the chimney while the internal electric pump does all the work. Techs view the results on the triple line display (hands-free testing). Quickly calculated and displayed on the screen, the SOX3’s combustion efficiency calculation is an excellent measurement to help determine the health of a furnace. Not only does the SOX3 test Natural Gas, Oil #2, and Propane, but it can be quickly and easily programmed to test any fuel. So non-conventional furnaces are just as easy to tune as conventional furnaces.

Yes, it can dial in any equipment that has a flue.
No, that is not consistent with the purpose or use of the device. This is used for a few minutes and when adjustments are completed it is removed.
You should wait 10-15 minutes after turning it on.
