Why is it important to maintain a proper combustion air supply?

Maintaining a proper combustion air supply is crucial for ensuring safe combustion in appliances that use fuel, such as gas furnaces or water heaters. Adequate combustion air is needed to support the burning process; insufficient air can lead to incomplete combustion. This results in the production of carbon monoxide, a highly toxic gas, which poses significant health risks. Furthermore, proper air supply prevents operational issues, such as backdrafting or flame instability, that can occur when combustion appliances are not receiving enough air. Overall, ensuring a proper combustion air supply is key to promoting safe and efficient operation of fuel-burning appliances.
