What is one of the core components of a flue system?

A flue system is essential for the safe removal of combustion byproducts from appliances such as furnaces, water heaters, and stoves. The primary function of the flue system is to transport the gases produced during combustion, including carbon monoxide, safely to the outside environment. A chimney or vent pipe is a crucial part of this system, as it provides the necessary pathway for these gases to leave the building, helping to prevent harmful accumulation indoors.

The chimney or vent pipe must be properly sized, constructed, and maintained to ensure effective venting. It often requires features like the correct height and diameter, proper insulation, and compliance with local building codes to function safely and effectively.

Other components such as gas pressure regulators, thermostat controls, and combustion chambers, while important for the overall operation of combustion appliances, do not serve the specific function of directing exhaust gases out of the home like a flue system does. Therefore, the chimney or vent pipe stands out as the core component of a flue system.
