The component that is crucial for drawing flue gases from an appliance to a vent is the draft inducer. This device creates the necessary negative pressure that helps to pull flue gases out of the appliance and into the venting system. It effectively enhances the performance of the venting system, ensuring that dangerous combustion by-products are safely expelled from the living space and do not pose a risk to occupants.

The heat exchanger plays a different role in the overall system; it is primarily responsible for transferring heat from combustion gases to the air or water that is being heated without mixing the two. The vent connector, while it is a component that helps in connecting the appliance to the vent system, does not actively draw gases but rather acts as a pathway for the gases to travel. Lastly, a flue damper regulates the flow of flue gases but is not involved in the process of drawing the gases from the appliance. Understanding these roles is key to ensuring proper venting and maintaining safety standards in gas appliances.
