Installation guide:
 1.1, Natural gas and coal gas: its specific gravity is lighter than air, so it suspends on the ceiling. Therefore, it is advisable to locate the alarm 30cm below the ceiling at a distance about 1.5m away from gas appliance. 
 1.2, Liquid petroleum gas: its specific gravity is heavier than air, so it sinks down on the bottom. Therefore, it is advisable to locate the alarm 30cm above the floor at a distance of 1 meter away from a gas appliance.
