1. Care of the wall-hung boiler
1. When the weather is getting warmer, it is necessary to drain the water in the wall-hung boiler and inject new water.
2. Turn on the water inlet switch, and close it when the pressure reaches 2 (the pressure should not exceed 3);
3. Open the vent valve of the wall-hung boiler, there will be a The strange smell “old water” is sprayed out;
4. When the “old water” is no longer spraying or flowing out, close the vent valve, and turn on the water inlet switch for the second time to pressurize to 2 or 3;
5. Repeat N times of draining and adding water until you are satisfied;
6. After deciding not to repeatedly flush, the final pressure should not exceed 1.5 (maximum no more than 2). In autumn and winter, you need to rinse and change the water again, but the pressure must not exceed 1.5. When the pressure is too high, you can open the vent valve of the last set of radiators and release some water.
Second, how to maintain wall-hung boilers
1. Check the ventilation system every year to prevent blockages and damage.
2. The high temperature safety glass must be fixed before using the fireplace.
3. To avoid accidental injury, do not let people who are not familiar with the operation of the fireplace use it.
4. The fireplace cannot be modified. The repaired fireplace parts should be installed in place before use.
5. The installation and maintenance of the fireplace must be carried out by professionals. It needs to be checked once a year.
6. Keep the fireplace clean and away from gas and other flammable gases or liquids.
3. Precautions for the use of household wall-hung boilers
1. Pressure
The pressure must not be too high, 1.2 to 1.5 is the most If it exceeds the proper range, the service life of the sealing parts will be reduced, and if the pressure is too small, it will not start.
2. For bathing and washing dishes at water temperature, we use the hot water function of the wall-hung boiler. Everyone is used to adding some cold water when the water is hot, but it is a big mistake! The hot water of the wall-hung boiler is not directly heated, so when we add cold water, we change the pressure in the circulating heating system. The pressure change will be transmitted to the corresponding circuit and chip by the induction device, and the furnace will follow the The pre-selected warmth rearranges the operation mode of each device, so repeating it will accelerate the aging of the device, and setting the water temperature at 2 according to the actual usage is already very hot.
3. Cleaning, after using it for a long time, we will find that the water output of the faucet is getting smaller and smaller, what is going on? The problem may appear on the faucet. The solution is very simple, just remove the filter of the faucet and remove the impurities.
4. When the water temperature rises to 60 degrees, the noise increases, and there is scale in the primary heat exchanger and the secondary heat exchanger, which needs to be cleaned in time.
4. Safety and maintenance of daily use of household wall-hung boilers
1. Installation of gas pipelines
Connection of wall-hung boilers and gas pipelines , must be installed and commissioned by trained professionals. The main point is to use a gas pipeline that meets the safety requirements and fix it with a clamp to prevent it from falling off. It is strictly forbidden to close gas pipelines and gas meters.
2. Leakage inspection of gas passages
From the gas meter interface to the gas valve of the wall-hung boiler and the interface of the fire exhaust, any connected interface must be airtight first After inspection, it can be used after passing the test.
The easiest and most feasible method in daily life is: before the wall-hung boiler is powered off or running, open all gas valves, apply soapy water (or diluted dishwashing liquid) to the interface, and observe. 3 to 5 minutes, if no bubbles are generated, it means that there is no air leakage. This method is recommended to be repeated every two months. When you smell gas, you should check it immediately! If conditions permit, you can use a hand-held flammable gas alarm to test each gas interface or install a gas alarm.
3. Check and replace
According to the quality of the gas hose, replace it regularly to prevent the danger of gas leakage caused by the aging and cracking of the hose.
4. Handling of unexpected situations
If you smell gas in the room, you should first turn off all gas valves, and do not turn on all household appliances or power switches, and do not use Mobile or landline! Then open the doors and windows for adequate ventilation. When you can’t smell the gas smell, turn off all electrical switches. Inform the gas-related professionals to come to the door (refer to the methods in steps 2 to 3 above) for inspection and elimination.
