Are natural gas appliances typically common vented with wood burning appliances?

Natural gas appliances and wood-burning appliances are generally not common vented due to the differences in venting requirements and the combustion products they produce. Common venting refers to the practice of using a single vent system for multiple appliances. Natural gas appliances typically require a specific venting method to safely expel combustion byproducts, which can differ significantly from the requirements for wood-burning devices.

Natural gas appliances produce water vapor and low levels of carbon dioxide as primary byproducts, while wood-burning appliances create smoke, particulate matter, and a greater volume of gaseous emissions, including carbon monoxide. Venting them together can lead to safety issues such as back drafting, where combustion gases do not exit properly, increasing the risk of harmful gases entering the living space.

Additionally, building codes and regulations often prohibit the common venting of these different types of appliances to decrease safety risks and improve efficiency. Each type of appliance has its unique requirements based on its combustion process, which further reinforces the idea that they should be vented separately. Therefore, it is accurate to state that natural gas appliances are typically not common vented with wood-burning appliances.
