For fuel-burning equipment, complete combustion is essential to ensure that the fuel is burned efficiently and safely. Complete combustion occurs when there is a sufficient amount of oxygen available to the fuel, allowing it to burn entirely and produce carbon dioxide and water as byproducts, rather than harmful substances like carbon monoxide or unburned hydrocarbons.

Adequate air supply leads to improved efficiency and performance of the equipment, reduces emissions, and minimizes the risk of hazardous situations that could arise from incomplete combustion, such as backdrafting and the accumulation of dangerous gases.

When fuel-burning appliances are designed, they must include features that promote an adequate air supply for complete combustion to protect both the integrity of the appliance and the safety of the inhabitants of the space.
