1) When the outlet temperature exceeds the allowable value, the over-temperature alarm is activated and the temperature continues to rise.

2) The pressure gauge and the thermometer all fail, and the liquid level of the liquid level gauge fluctuates drastically. Although measures are taken, it still cannot be restored to normal.

3) Defects such as bulging, deformation, cracks, etc. of the pressurized parts of the hot water boiler are serious threats to safety.

4) The circulation pump is completely damaged and cannot be operated.

2) Turn off the circulation pump.

3) Open the oil drain valve, put all the heat transfer liquid in the system into the oil storage tank, then cut off the contact between the hot water boiler and other equipment, and close the inlet and outlet valves;

4) Open the furnace door, see the fire door, and the chimney baffle to speed up the natural ventilation and cooling of the furnace.
