How to use gas water heater and cooker safely

1, gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion and heating to achieve the purpose of preparing hot water.

2. The basic working principle of gas water heater is that cold water enters the water heater, flows through the water-gas linkage valve body, pushes the water-gas linkage valve under a certain water pressure difference, and at the same time pushes the DC power microswitch to connect the power supply and start the pulse igniter.

3. Gas water heaters, like many products, should follow certain rules in use. As long as it is installed according to the regulations, operated according to the correct procedures and well ventilated, it will be very safe to use, convenient for life and beneficial to mankind. If you violate this rule, something will definitely happen.

Second, the safe use of gas water heaters and cookers.

1. When purchasing gas burning appliances, you must refer to the Catalogue of Gas Source Adaptability of Pipeline Gas Burning Appliances. Do not install or use gas burning appliances that do not meet the requirements of gas source; Do not install, modify or dismantle pipeline gas facilities and gas appliances without authorization.

2. The gas water heater must be equipped with a flue and effectively connected with the outdoor. The length of the flue should not be too long. The gas connecting pipe of the water heater shall be aluminum plastic pipe, and rubber hose shall not be used.

3. The gas stove should be installed in the kitchen with natural ventilation and natural lighting. Cooking stoves can be connected by metal corrugated pipes or special gas hoses. The hose is short in life, easy to age, loose in joint, not hot, easy to be bitten by rats and easy to block gas. It is recommended to use special metal bellows for gas. Rubber hoses must not pass through walls, ceilings, floors, windows and doors. When connecting with household gas appliances, both ends of the hose must be fixed with clamps, and there can be no joints. The length of rubber hose shall not exceed 2m, and it shall be replaced every 65,438+08 months from the date of installation. When using metal bellows, pulling must be avoided. If the metal bellows is separated from the cooker or gas pipeline when the cooker is replaced or the gas position is moved, it must be replaced with a new metal bellows and reconnected.

4. Gas users should use qualified gas burning appliances, timely replace gas burning appliances and connecting pipes that have been explicitly eliminated by the state or whose service life has expired (the service life of gas stoves and water heaters is generally 8 years, and if the service life of the products is indicated, the service life of the products shall prevail), and pay the gas fee according to the agreed time limit.

5. Users should always check the tightness and integrity of gas appliances, gas pipelines and connectors. It is forbidden to check the leakage point with naked flame, and repair or replace the gas immediately if it is found to be leaking or aging (the maintenance and replacement of gas appliances should contact the manufacturer, the maintenance and replacement of other indoor gas facilities should contact the gas company, and the installation or maintenance of gas pipelines connected with gas appliances should be carried out by professionals).

Third, matters needing attention

When the water heater is used, one is to use oxygen to support combustion, and the other is to produce smoke. Under normal circumstances, the content of carbon monoxide in flue gas is very small, but in the case 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, there is less and less oxygen in the air and more and more carbon monoxide. 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, symptoms such as tinnitus, palpitation, vomiting and limb weakness may also occur. The use of water heaters must be well ventilated and must not be sloppy.
