1. find a professional technician to install it in strict accordance with the safety requirements.

2. The gas water heater must be installed outside the bathroom, and a smoke exhaust pipe must be installed to ensure the smooth discharge of smoke.

3. Users who use artificial gas must entrust professionals to clean the burner regularly (every 3 months or half a year).

4. The bathroom room must be well ventilated.

5. gas leakage prevention: always use soapy water to check whether each gas connector, gas pipeline or hose leaks. Once the rubber hose is found to have cracks, it must be replaced immediately. In case of gas leakage, it is necessary to immediately close the gas valve, open the doors and windows for ventilation, and disable the telephone and electrical appliances. Users who use liquefied petroleum gas are strictly forbidden to put cylinders upside down or sideways. In addition, pay attention to timely replacement of products that have exceeded their service life. Keep in mind three notes and four rules for water heaters in winter.

6. When the water heater is used, it needs oxygen to support combustion, and it also needs to produce flue gas. Under normal circumstances, the content of carbon monoxide in flue gas is very small, but under the condition of insufficient air supply, the content of carbon monoxide in flue gas will increase greatly. When the water heater is used under the condition of poor ventilation, the oxygen in the air is less and less, and carbon monoxide is more and more. Lack of oxygen makes people suffocate and carbon monoxide makes people poisoned. Carbon monoxide is a colorless, odorless and non-irritating toxic gas. After poisoning, besides headache, dizziness and nausea, there may also be symptoms such as tinnitus, palpitation, vomiting and limb weakness. The use of water heaters must be well ventilated and must not be careless.
