Where should install the gas detectors

1.Please confirm the induced gas in heavier than air or lighter than air,the gas is heavier than air:LPG etc. the gas is lighter than air: Natural gas, marsh gas etc.

2.Chooseing the suitable position to install the Detector according to the gas specific gravity.Detecting the gas heavier thanair: Installation height from floor 12-40 in,semi-diameter to gas source<60 in. Detecting the gas lighter than air,Installation height from the celling 12-40 in,semi-diameter to gas source<60 in.

3.To avoid installing the detector close to the following sources of interference:Direct air flow from vents,fans,doors,windows,sources of steam,oil vapor etc.
