What do we call the pipe or duct that connects a fuel gas burning appliance to a vent or chimney?

The correct terminology for the pipe or duct that connects a fuel gas burning appliance to a vent or chimney is referred to as a vent connector. This component is crucial in the venting system because it serves to safely channel combustion gases from the appliance to the outside atmosphere, ensuring proper ventilation and reducing the risk of backdraft or leakage within the living space.

The term "vent connector" distinguishes it from other types of pipes and ducts used in related systems. While it shares similarities with what might be described as a vent pipe or flue connector, the vent connector specifically pertains to the transition between the appliance and the larger venting system. Ensuring that proper vent connectors are used is vital for compliance with safety regulations and for the efficient operation of gas-burning appliances.

Understanding the difference between these terms is important for professionals in the field, as it involves knowledge of proper installation practices and regulations surrounding the safe and effective venting of combustion gases.
