You know, Im almost shocked by some of the comments Im seeing posted in here about CO. Im just going to assume that there is much unknown advice to the average homeowner about CO? You would have to be absolutely NUTS to knowingly expose yourself to 50ppm of CO continuously! Even 14PPM! Below is a level that may be safe (009 PPM) but I still wouldnt knowingly expose myself to that or any other level
ASHRAE 62-89 (American Society of Heating, Refrigeration and Air Conditioning Engineers) 009 PPM The maximum allowable concentration for continuous (24 hr) exposure. ASHRAE states the ventilation air shall meet the out door air standard referenced to EPA and 9 PPM.
You also, for the most part, cannot use a household CO detector to detect a CO leak in a furnace plenum. The amount of air from the blower in the furnace dilutes the CO so much that it takes a long time and/or large concentration for your detector to register the CO. Your assumption of a gas stove putting out CO is incorrect also. If it is putting out CO it is burning poorly or it is causing incomplete combustion. If it is, GET IT FIXED! Dont rely wholy on your UL listed CO detector. Read the info. See what kind of levels your detector alarms at. You might find it "alarming". Bubba
