What is the primary purpose of a gas venting system?

The primary purpose of a gas venting system is to remove combustion gases from appliances. This is crucial because appliances powered by gas generate harmful byproducts during the combustion process, such as carbon monoxide, water vapor, and other gases. Effective venting systems ensure that these products are safely expelled from the home or building, preventing the risk of backdrafting and possible health hazards associated with inhaling toxic gases.

Proper venting not only maintains indoor air quality but also aids in the efficient operation of the gas appliances. Ensuring that the combustion gases are vented outside allows the appliances to function correctly and helps avoid issues related to pressure differentials within the home that could lead to reduced efficiency or potential hazards.

While other choices touch on different aspects related to gas and its usage, none directly address the critical function of ensuring that combustion byproducts are vented properly and safely out of living areas.
