Inspection and Lubrication: Regularly check the burner oil pump, pipelines, and connections for looseness or leaks. Manually rotate the oil pump to ensure its flexibility. Add lubricating oil to the bearings; the oil level should be maintained near the center line of the oil gauge, and promptly replace or top up the lubricant as needed.

　　Cleaning and Filtration: Clean the fuel tank once a month to remove dirt and moisture. It is recommended to clean the oil filter every 2–3 days, or adjust the frequency based on usage—e.g., every two weeks. Gently scrub the burner nozzle with a used brush or steel needle, avoiding the use of oily rags to prevent clogging of the air holes.

　　For precalciner burners, the component cleaning cycle can be set at 2–3 weeks, with particular emphasis on cleaning parts such as the flame plate, electrodes, and nozzles.

　　Dust Removal and Purification System Maintenance: Every 2-3 months, open the ash-cleaning door of the combustion chamber to remove accumulated dust; regularly replace the filter bricks (such as [Ca(OH)2]) in the flue gas purification chamber.

　　During operation, monitor the differential pressure gauge reading. When the pressure difference reaches 0.02 MPa, promptly flush the filter element.

　　Component Inspection and Adjustment: Regularly inspect the combustion chamber, impeller, flame detector, and ignition electrode; remove oil stains and carbon deposits; ensure that the flame detector is clean and dry.

　　Check the gas pressure quarterly (e.g., about 2000 Pa for household natural gas), and inspect the ignition system gap (typically 3–5 mm) and fan operation every six months.

　　Safe Operation and Environmental Management: Before maintenance, be sure to disconnect the power supply and gas source, and proceed only after the equipment has cooled down. Keep the equipment surface clean and dry, and avoid allowing water droplets to enter the air vents, which could cause rust.

　　The burner’s operating site should be located away from flammable and explosive materials, and fire-extinguishing equipment must be readily available.

　　Regular Deep Maintenance: It is recommended to contact professionals annually for a comprehensive inspection, which includes disassembling and thoroughly cleaning the burner, testing the thermal exchanger’s seal integrity, and verifying the functionality of safety devices (such as flame-out protection).

　　For critical components (such as oil nozzles and flexible couplings), replace them regularly according to the manufacturer’s recommendations (e.g., oil nozzles once a year).
