1.Do not empty the water.

　　In order to make the water pressure of the gas wall-hung boiler normal, when using the boiler in summer, do not empty the water in the boiler and the pipeline, and ensure that the water pressure is between 1 and 1.5 bar.

　　Since the heating of the gas wall-hung boiler is a closed system, the water in the boiler and pipes will be vented to form a humid and oxygenated environment, which is prone to corrosion of boiler waterway components and pipes. Therefore, the boiler may be damaged due to low water pressure burn out.

　　2. Pay attention to switch to summer mode.

　　When using the wall-hung boiler in summer, it needs to be switched to "summer mode", and the boiler can fully meet the user's demand for hot water in the bathroom.

　　3. Do not switch frequently.

　　Many people will increase the frequency of bathing in summer. Every time the hot water faucet is turned on, the boiler is turned on at the same time. If the boiler is far away from the faucet, there will be a delay of a few seconds of hot water, so frequent switching of the hot water faucet will increase water and gas consumption.

　　4.The hot water faucet should not be turned on to the maximum at once.

　　When using a boiler to provide hot water in the bathroom, turn on the hot water faucet until the hot water flows out. There will be a delay of several seconds. Users need to pay attention when using hot water. The hot water faucet should not be turned on to the maximum all at once. Wait for the boiler to start until the ignition delay, and then adjust the the water flow as needed to reduce the waste of water resources.

　　5. If you do not use it for a long time, please turn off the power.

　　If the gas boiler is not used for a long time, it is necessary to close the water valve, gas valve and power supply of the boiler. It can effectively avoid unnecessary loss of energy and avoid damage to the boiler during thunderstorms in summer.

　　6. It needs to be turned on regularly.

　　If there is no need to use the boiler in summer, it cannot be turned on until winter. Because the boiler is in a closed system, long-term shutdown will cause stagnation and fixation, and it needs to be turned on every 1 or 2 months.

　　7. Regular cleaning to prolong service life

　　When using the boiler for a long time, it needs to be cleaned regularly, because there will be scale deposits in the heating system, which will greatly reduce the thermal conductivity efficiency, and will also cause waste, which is prone to large noise.

　　Summer is the best time to clean the boilers. Under normal circumstances, boilers should clean and maintain the filter liner and related pipes every one to two years. The service life will be improved, the work efficiency will be improved, the occurrence of some failures will be reduced, and the safety performance will be improved.
