What is a draft inducer's role in a gas furnace system?

A draft inducer plays a crucial role in the operation of a gas furnace by assisting in the removal of combustion gases from the furnace to the outside atmosphere. Its primary function is to create a negative pressure within the flue system, which ensures that hazardous gases, such as carbon monoxide, are effectively expelled, thereby maintaining a safe environment and promoting efficient combustion. By aiding in venting, the draft inducer also helps to establish the necessary airflow that ensures the furnace can operate at optimal efficiency, thus improving overall performance and safety.

This function is particularly important in modern high-efficiency furnaces, where proper venting is essential to prevent backdrafting and ensure that the combustion process operates smoothly. The other choices, while related to furnace operation, do not accurately describe the specific role that a draft inducer plays within the gas furnace system.
