Guide: Before the natural gas boiler is put into operation, the technicians should study in detail the random manual and various other technical materials, and have a deep understanding of the various technical performance of the equipment. And work out the operating procedures for the use of equipment, and the boiler can be put into operation only after necessary technical training for the use or operator of the natural gas boiler.

　　1. Before the natural gas boiler is put into operation, the technicians should study in detail the random manual and various other technical materials, and have a deep understanding of the various technical performance of the equipment. And work out the operating procedures for the use of equipment, and the boiler can be put into operation only after necessary technical training for the use or operator of the natural gas boiler.

　　2. Maintenance personnel should maintain the equipment in strict accordance with relevant regulations to keep the equipment in good condition.

　　3. During the operation of a natural gas boiler, when one of the following situations occurs and the protection does not work, the boiler should be shut down urgently:

　　(1) The water level of the natural gas boiler is lower than the visible edge of the lower part of the water level gauge. The water supply is continuously increased and other measures are taken, but the water level continues to drop;

　　(2) The water level of the natural gas boiler exceeds the maximum visible water level (full water), and the water level cannot be seen after the water is discharged;

　　(3) The soft water system is faulty, water cannot be fed into the boiler and the boiler water level is lower than the lower visible edge of the water level gauge;

　　(4) When the circulation pump of the natural gas boiler fails to operate normally;

　　(5) Natural gas boiler components are damaged, endangering the safety of operating personnel;

　　(6) When the temperature of the boiler water rises sharply and out of control;

　　(7) Other abnormal conditions endanger the safe operation of natural gas boilers.

　　4. When the boiler is shut down due to a water shortage accident, it is strictly forbidden to supply water to the boiler and conduct steam and sewage operations.

　　5. The natural gas boiler room should be well ventilated.

　　6. Start the burner after the circulating pump is running normally, and the valve of the circulating system should be opened. It is forbidden to start the burner first, and then start the circulating pump or open the valve suddenly after the boiler heats up.

　　7. If the boiler circulating pump fails and stops running and the boiler protection system does not work, causing the boiler to experience "dry burning", it is strictly forbidden to add water to the natural gas boiler or turn on the circulating pump.

　　8. To stop the furnace, press the stop button on the operation screen to stop the combustion of the burner and close the intake valve. Disconnect the power supply of the controller and the main power supply of the boiler.
