The wall-hung boiler is a precision equipment that integrates water and electricity, and safety is very important. Today, I will share with you some safety knowledge and energy-saving technologies for using wall-hung boilers. At this critical moment of cooling, you can play with the wall-hung stove and enjoy a warm, comfortable, and beautiful life.
Safety precautions for the use of wall-mounted boilers
1.The type of gas specified on the product nameplate label must be used. Natural gas, man-made gas, liquefied petroleum gas and biogas are not used interchangeably.
2.Wall-hung boilers should be installed in kitchens or enclosed balconies, and are not recommended for installation in bathrooms.
3.The smoke exhaust pipe cannot be led to the public smoke exhaust pipe;The innermost suction hole on the outer pipe of the smoke exhaust pipe must protrude from the outer wall.
4.In the event that the ambient temperature may freeze, it is essential to keep the wall-hung boiler energized and the gas energized. Even if the wall-hung boiler is in the closed state, as long as the gas is unobstructed (the IC card gas meter should ensure sufficient advance payment), the main circulation pipeline is unblocked, and the water pressure of the heating system is normal, the anti-freezing function of the wall-hung boiler and the anti-jamming protection of the water pump will be effective.
If one of the above conditions is not met, wall-mounted boilers, pipes, and radiators may freeze and even cause safety incidents. During the winter months, if there is a power outage or power outage for an extended period of time, or if you do not live in your home for a long time, or if there is a possibility of freezing, the water in the heating system should be drained first to prevent freezing and damage.
5.If the gas wall-hung boiler freezes (or may have frozen) due to a power outage or gas interruption, it is strictly forbidden to start and ignite, otherwise it may cause ** accidents. If there is a power outage or a power outage lasting more than 2 hours (please determine according to the local weather conditions, the outdoor temperature of the day and the insulation of the house, this time is for reference only.) In the event of a power outage or power outage, some wall-mounted boilers installed on the balcony may have a shorter freezing time), drain the water from the heating system, cut off the power, and close the gas valve.
At the same time, you need to close the tap water inlet valve under the wall-hung boiler, and then open the hot water valve (or shower head) to drain the water from the hot water pipe. Check with your utility company, electricity company, and gas company to confirm the duration of the outage and gas outage. If it has frozen, please contact the wall-hung boiler after-sales service center for processing. This processing tool can use a high-powered electric hair dryer to ensure that all ice in the furnace's internal pipes and heat exchanger is melted and that the external circulation pipes are clear and free of ice before attempting to start the machine.
The correct way to use the gas wall-hung boiler
1.The water supply pressure reaches 10-1.After 5 bar, be sure to close the water supply valve. Otherwise, the system's overpressure relief valve will continue to leak, which may wet the contents of the room;On the other hand, if the tap water is cut off, the wall-hung boiler will stop working due to water loss.
2.Open the air valve to start the machine and then adjust the winter and summer mode, press the up and down keys to adjust the temperature of the heating or bath water. If the ignition is not triggered, the water pump will usually jam. Use a flathead screwdriver to rotate the water pump impeller a few times. If the problem cannot be solved, please contact the after-sales service personnel.
3.If the overpressure is too high during accidental water replenishment, it can be drained through the drain valve or exhaust valve on the radiator. For underfloor heating pipes (or radiators) that do not have a drain valve installed, draining and depressurizing can be done using the following method: turn off the tap water valve Open the make-up valve counterclockwise and then turn on the hot water valve (or showerhead) to release the pressure when the pressure reaches 10-1.At 5 bar (optimal pressure range), turn off the hot water valve (or shower head), then turn off the supply valve clockwise, and finally turn on the tap water valve (if it is not opened, there will be no domestic hot water).
When the wall-hung boiler is working, the pressure increases, which is normal and is caused by the expansion of water during the heating process. Most wall-hung boilers have overpressure protection and pressure relief devices when the system pressure exceeds 30 bar (3.)0 kg), these devices can relieve pressure.
