Measurable gases: natural gas & liquefied petroleum gas & carbon monoxide;

Installation Notes:

Install the detection alarm according to the specific gravity of gas:

    City gas is lighter than air and will be suspended in the ceiling, so the alarm should be installed at a suitable location within 0.3-1.2 meters below the ceiling and within 1.5 meters from the gas source radius;

    Liquefied petroleum gas: Because it is heavier than air and will be deposited in low-lying places, the detector should be installed at a suitable place within 0.3-1.2 meters of the ground surface and within a radius of 1.5 meters from the gas source.

Precautions:

Don't face the oil smoke and steam of the stove;

Do not install in a well-ventilated place, such as by a window;

Do not install it in the bathroom or other places with large water vapor, which may make the sensor invalid;

Precautions for use:

Do not directly clean the product with chemical spray;

Do not rinse the product with water or allow water to enter the detector;

Do not arbitrarily dispose the detector, disassemble and disassemble it, etc.

Do not use irritating substances, such as pesticides, paint, and a large amount of alcohol, near the detection alarm;
