2008-03-03 · The production of carbon monoxide (CO) in the flue gases should be kept below 100-ppm air-free, even though the allowable limit in the stack is 400-ppm air-free. Any time CO is rising and unstable at any level, from 1 ppm to 400 ppm during the combustion process, the burner should be shut down and/or immediately tested and repaired.

Winnipeg fire crews measured carbon monoxide readings of 70-90 ppm; gas becomes dangerous at 10-20 ppm CBC News · Posted: Dec 24, 2020 9:53 AM CT | Last Updated: December 24, 2020 Chronic carbon monoxide poisoning can come from hot water heaters and furnaces when the exhaust is not direct vented or sealed. In the above photo, the hot water heater exhaust is supposed to flow as a result of gravity up into the hood over the top of the exhaust pipe.

30-70 +/-3 = lowest CO range in consumer CO alarms are required by UL2034 to sound, but only after this level has been continuously sustained for over 30 days. This is meant to (and effectively does) insure that consumer CO alarms never provide any warning at CO levels below 70ppm.
