Can natural smells set off the gas alarm attached to a plug-in carbon monoxide detector?

May 27, 2007 by bluemoon | Posted in Other - Home & Garden

When changing the swill in the kitchen , the alarm for explosive gas went off! Have read that methane from a diaper pail could ideal the alarm to sound; was wondering if garbage containing some old catfood, vegetables etc. could do the same.

Working of the combustible gas detector could be caused by methane generated by decomposition of hydrocarbons such as those you describe. I would meditate on, though, the detector would have to be very close to where the methane is generated, and at a level higher than the inconsequential in reference to of generation. Methane is somewhat lighter than air, unless is is colder than neighbourhood air.

Is it normal to have a gas smell near a gas furnace?

Apr 02, 2008 by Whobitty | Posted in Maintenance & Repairs

We have been in our domicile for 2 1/2 months. Prior to moving in, we had a diagnostic exam run on the furnace. The test came out ok except that the flue fan had to be replaced. I have smelled a unlikely gas smell on occasion when opening the furnace closet, markedly right before the furnace kicks on. We have a carbon monoxide/explosive gas detector plugged in about five feet from the furnace. It has never gone off. Still, I had the gas Pty check and they said it was ok too.

Should I still be concerned? Today I in reality smelled the gas through our vents upstairs and, subsequently, when I opened the furnace closet not crave before the furnace kicked on.

No, this is not rational! A carbon monoxide monitor only measures the amount of CO after the burner is operating. An explosive limit detector will only arouse when the explosive gas content in the room is high enough to cause an blast.
You report that the gas detector has never gone off. How often have you tested it to ensure that it is working? Have you ever replaced the battery in it? You should supersede the battery on the weekend of the time changes from Full view Savings time to Standard Time and investigation the detector on the 1st of each month.
You should not smell any odors from the natural gas when the furnace lights. Yes, it is more overused with heating oil to have an odor, but not with any other fuels. Even though the gas company found no odors, I'd still call them again and article a gas odor in the room.
