ok. Thanks. Right now, the detector in my bedroom is just under 6 feet from the floor. The one in the living is higher (cathedral ceiling) and the one in the utility room is only one foot from the ceiling (no where else to put it).neilpilot wrote: ↑Wed Jun 07, 2023 7:47 amWhile CO detectors will function when mounted high, that's certainly not optimal. Since CO essentially mixes with air, the best position is 3-6' off the floor.student wrote: ↑Wed Jun 07, 2023 6:41 amThanks. I have the CO detectors mounted high.niagara_guy wrote: ↑Wed Jun 07, 2023 6:30 am I just looked at my gas detector and didn't see any markings on it, I believe I bought it on Amazon. I believe for natural gas the detector should be mounted up high since natural gas rises (I believe down low for LPG detector since LPG is heavier than air).
I want a CO detector near sleeping area, so I have separate detectors for CO and natural gas.
Possible gas leaks? (Update and new questions)

Re: Possible gas leaks? (Update and new questions)
Contrary to popular opinion gases in air neither rise, nor fall. Below 80,000 meters or so turbulence mixes them into a homogeneous mixture.

This is certainly incorrect, in the context of the thread's subject of a gas leak. I've responded to many gas leaks over my 45 years in industry, both indoors and outdoors. Stratification is highly dependent on relative gas density, but it typically does occur. This includes incidents involving Hydrogen, CO2, H2S, Chlorine, Bromine, Methane, Methyl Chloride, and several others.

Re: Possible gas leaks? (Update and new questions)
Gases rise and fall relative to one another based on their molecular weight (density).
Helium will be found at the top of a room, refrigerant gases at the bottom, and other gases somewhere in-between based upon the respective molecular weight
