When the household USES natural gas, the gas detector should be installed within 300mm from the ceiling. When the household is using LPG, the gas detector should be installed within 300mm from the ground. If the combustible gas detector is not reliably grounded, electromagnetic interference cannot be eliminated, and the voltage will be affected.

Therefore, regular cleaning and maintenance of combustible gas detector is an important work to prevent failure.
