I have a gas water heater outside - do I need a carbon monoxide detector?

Answer
When you are burning indoors any type of liquid or solid fuel for heating, cooking or other use, you should have an active carbon monoxide detector installed in your home.

If you have fuel-burning appliances on more than one level of your home, you should have a carbon monoxide detector on each floor. For example, if you have a gas range on the main floor and a wood-burning fireplace on the lower level, you should have detectors on each of these floors.

Such fuel-burning appliances are generally tested and safe to use, but should there be a clogged vent line or any part of the appliance that becomes faulty, it could release hazardous levels of carbon monoxide in your home and death can occur within minutes. But you can keep your family safe by using a carbon monoxide detector which can alert you to the presence of this silent toxic gas.

If you work regularly on running vehicles in a closed garage, you should also consider installing a unit in that area.

Hi, My carbon monoxide detector said 11 about an hour ago, The pilot light went out on the gas fireplace. Is 11 bad? I have animals in my house and I want to make sure they are going to be okay. The detector says 0 now.


Answer
The carbon monoxide seems to be coming from the gas fireplace since carbon monoxide is produced by the incomplete burning(combustion) of solid, liquid, and gaseous fuels.If you smoke a couple of cigarettes, or someone had been smoking a cigar in the last hour, you could hit 11ppm CO in your home. Cigarette smokers exhale between 4 and 9 ppm CO all the time. And, if you're in a city, it's possible that the background CO rises to that level during the day. The mechanic's meter might hit 12-15 ppm standing in the middle of your back yard!
Besides, 11-12ppm CO may be ambient conditions and nothing to really worry about. It could also be "left over" output from cooking or some other activity. To make it even more complicated, the cheap CO meters and many residential CO detectors are cross-sensitive to other gasses, like methane, butane, alcohol, aerosols, etc. I've seen "Pam" cooking spray put a CO detector into alarm.
Besides, if you had been cooking, using the oven, heating water on the stove, or had a door or window open that could cause your flue(any duct or passage for air, gas, or the like) to down draft, you might see 5-20ppm in the house for a period of time. An oven will produce anywhere from 20 to 600 ppm when operating. Most run in the 30-100ppm range.

You should still check with the local firedepartment or call the company that made The detector your using.
