What is the function of the flue pipe in an oil burner system?

The flue pipe plays a vital role in the operation of an oil burner system by directing exhaust gases safely outside of the building. When fuel oil is burned in the furnace, it produces combustion gases, which include harmful by-products such as carbon monoxide. The flue pipe is designed specifically to carry these gases away from the burner and vent them outside, preventing the accumulation of toxic fumes inside living spaces and ensuring proper ventilation.

Without a properly functioning flue pipe, there would be a serious risk of hazardous gases entering the home, which could endanger health and safety. The flue pipe also helps maintain the desired draft in the combustion chamber, which is necessary for efficient burning and operation of the system. Understanding this purpose helps in the maintenance and troubleshooting of oil burner systems, ensuring they operate safely and effectively.
