Have you taken the HVAC Know It All quiz? I'm just a marketer these days, so I am happy with my score of 20. I missed a few of the questions, but to be honest, I never did a combustion analysis back in the day. I'd just checked CO levels and monitor the flames. I didn't even know there was another way until AFTER I stopped running calls. How did you do? What tripped you up? Motor Maverick....I like the name!
