Chimneys, Flues, and Vents for You

In this article, I will attempt to explain, in simple terms, the basics of gas appliances, with a focus on their flues and the importance of a correctly designed flue.
Your gas appliances are, usually, your: oven/stovetop, water heater, furnace, and possibly your clothes dryer. There are many different types of each of these appliances but if we go to the bare bones of it, your gas appliances need air to burn gas to create heat, and as a result of that combustion also release as byproducts: water, carbon dioxide, carbon monoxide, Nitrogen Oxides, Sulfur Dioxide, and Particulates.(1) These byproducts need to exit the appliance and your home for it to continue to work properly and for you and your family to stay healthy and safe.
