    Miller doesn't mention combustion in the manual. They mention draft and adjust for efficiency. 🤪

    I take the readings over fire. You can't put the analyzer probe over fire, but I have one of these for EK boilers that I also use on Miller/Nordyne with the concentric venting. Wrap a rag around it at the door to prevent drawing air.
