Installation
According to specific gravity of natural gas to install gas leakage alarm. Natural gas and coal gas: Its specific gravity is lighter than air, so it suspends on the ceiling. Therefore, the alarm should be installed in the area that is less 0.3~1.2 meter than the ceiling and within radii 1.5 meter far from gas leakage. Liquid petroleum gas: Its specific gravity is heavier than air, so it sinks down on the bottom. Therefore, the alarm should be installed in the area that is 0.3~1.2 meter far from ground and within radii 1.5 meter far from gas leakage.
