co from antifreeze

making sure I did not have a coincidence, I rechecked everything on the boiler including running the range, electric drier and all fans to make sure all was good.
Spent half the day on site then more time off calling my supplier and rep.

The leak was not even that bad, tops one cup.

Better safe than sorry.

Thanks Jim

    co from antifreeze

    I put a CGA boiler in last january, got a call Monday
    night. Funny smell from the boiler room, NSI 300 co alarm reading 12 ppm with peak of 18 ppm first floor near kitchen 9ppm and second floor 7ppm. Yes still low but whats up.

    A full combustion, gas pressue and draft test was done on start up all was good.

    We had applies 44% anti freeze to the system. Temperature pressure gage devleoped a leak that went over the sections and down into the Burner pan. I changed the gage, cleaned the pan and burners. As a precoution took apart the smoke pipe, checked the flue, fired the boiler and did again a compleat start up analysis all was good.

    Rep from the boiler manufacturere stated that the antifreeze cooking off is what gave the co reading, question is was it co from a non toxic source or was it the sensor picking up a fals gas.

    According to material safety data sheets Propylene glycol can produce carbon monoxide and other aldehydes when heated to higher temperatures.
