Can't locate CO detector

A CO detector can be mounted at any level as it mixes easily with air and that's why they combine them with PP detectors. That's also why the plug in types are so common for residential use.
CO is only ever so slightly lighter than air - not enough to matter.

Example

Propane is heavier than air and a detector is normally mounted low. Ours is on the slide side wall behind the dining table chair, less than a foot above the floor. Chris
