Operation 
In a direct fired make-up air unit, the air that is to be heated is passed directly over an open flame. No heat exchanger is involved. This design results in an extremely efficient system that achieves 100% combustion efficiency and a 92% overall thermal efficiency (with 8% of the total heat lost in the latent heat of water formed in combustion). The combustion is so complete that any remaining combustion products are well within code prescribed safety limits. Because of these benefits, direct fired units are ideal for make-up air or heating and ventilating applications.
