2 Thoughts to “Video: What you may not know about your CO detector”

    I was told that the co detector should be mounted low on the wall or near the floor because co is heavier than air and will fill the coach from the floor up. Was this bad info?

      Hi, Jim. Thanks for asking about CO detectors. Here’s a paragraph from a recent post (Don’t be a carbon monoxide victim) from Russ and Tina De Maris which should help clarify this for you:
      “Where should CO detectors be located? CO is slightly lighter than air, hence it rises. So putting the detector above the floor is right. You might even place it on the ceiling, but generally about five feet above floor level is best. If you have a big rig, make sure you install it close to your sleeping area so you’ll be able to hear the alarm when you’re asleep. Of course, follow the manufacturer’s instructions on ‘siting’ the unit.”
      BTW — LP is heavier than air, so an LP leak detector should be located near the floor. Here’s a great (and short) video from and Chris Dougherty, Certified RV Technician, about RV propane leak detectors:
      Stay safe. 😀 —Diane at
