What is the purpose of a vent connector in a fuel-fired appliance setup?

The purpose of a vent connector in a fuel-fired appliance setup is to facilitate the safe removal of combustion gases from the appliance to the exterior of a building through a venting system. By connecting the appliance to a vent, it ensures that harmful gases, such as carbon monoxide, are properly expelled outside, reducing the risk of accumulation within the living space. The vent connector is specifically designed to manage the flow of these gases and maintain the performance and efficiency of the appliance.

In contrast, connecting the appliance to the gas line pertains to supplying fuel for combustion, which is not the function of a vent connector. Similarly, providing electrical supply is essential for appliances that require electricity to operate, but this is unrelated to venting. Lastly, connecting two appliances together is not relevant in the context of venting; vent connectors are designed for individual appliances to ensure that each can effectively expel gases without interference from others.
