I may be "old school" but IMHO propane/gas detectors are placed near the floor since propane is heavier than air and CO detectors are placed near the ceiling since CO is lighter than air. How one instrument can be effective.
And yes - even a dog sleeping near a propane detector can set one off!
Any one - please enlighten this oldie!
CO is just barely lighter than air. It is so close in weight that it mixes evenly with air. The suggested placement is at the same level as sleeping but the level is not as critical as a smoke or LP detector. This is why the combo unit is ok with both at the floor level. It is not perfect but should still sound an alarm prior to serious issues.
CO can rise rapidly if it is given off with heated air but at that point it should be mixing fairly quick.
