Cleaning<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The burner is one of the most critical components of an oil boiler. During maintenance, the technician should disassemble it for thorough cleaning, removing any fuel residue that could obstruct its operation. Regular cleaning of the burner ensures efficient combustion and reduces the risk of harmful emissions.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Heat_Exchanger_Inspection\"><\/span><span style=\"font-weight: 400;\">Heat Exchanger Inspection<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The heat exchanger is responsible for transferring the heat from the fuel to the water circulating through the heating system. Over time, soot and other residues can build up, reducing its efficiency. Regular cleaning of the heat exchanger improves heat transfer and reduces fuel consumption.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Tightness_Check\"><\/span><span style=\"font-weight: 400;\">Tightness Check<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The tightness of the boiler circuits is crucial to prevent fuel leaks and ensure the system\u2019s safety. During maintenance, the technician must inspect all connections and joints to ensure there are no leaks. This includes checking the fuel tank, pipes, and valves.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Chimney_Inspection\"><\/span><span style=\"font-weight: 400;\">Chimney Inspection<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The chimney is another important component that requires attention.
