gases: carbon monoxide, natural gas, manual coal gas,
marsh gas, etc.
2. Choosing the suitable position to install the detector
according to the gas specific gravity. Detecting the gas
heavier than air: Installation height from floor: 0.3-1.0
m, semi diameter to gas source: < 1,5 m; Detecting the
gas lighter than air: Installation height from ceiling: 0.3
-1.0 m, semi -diameter to gas source: <1.5m (refer to the
