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
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".
