: we have a NEW 100K/hr gas boiler that smokes like a freight train. O2 looks good. any suggestions?
On natural gas if the smoke is white, you have too much excess air. If its dark or black smoke, you have too little excess air. If the smoke is not white and your O2 looks good, you may be getting an erroneous O2 reading. Check and recalibrate the analyzer.
