Working on a oil boiler in a basement today. Shut the boiler off to drain two zones. Started to solider for about 5 minutes about 25' away from a CO detector (outside the boiler room). The CO detector goes off, fire/police show up because of central station.
Fire department chief comes down to the basement with his portable CO detector and the CO starts to rise to about 70ppm. Fireman comes down with a little better unit and his is reading 50ppm and rising, tops off about 65ppm. I open a window to vent out the basement. Homeowner calls oil tech to come take a look. I get my Fyrite pro about an hour later to see whats going on.
My fyrite reads about 14ppm after 2hrs from the fire department came. Meanwhile the boiler been off the whole time. I fire the boiler with my fyrite close by, it never gets above 14ppm.
Oil tech comes in checks the draft in the flue and chamber, draft is very good at both points. No attic fans on on a/c on and nothing else on in the house.
Does anybody have clue what it could have been. I'm stumped
