ABSTRACT:
A gas-fired oven is disclosed wherein heated air is delivered to an oven's interior from a gas burner located outside the oven in a way to enhance the convection heating properties and capacity of the oven. This is accomplished by means of a conduit which receives air heated by the external gas burner and internally discharges this heated air into the return air path of a blower used to recirculate hot air within the oven. The internal discharge end of the conduit is located adjacent to the blower's return air path so that the conduit does not obstruct the recirculating air. The external gas burner may be either an atmospheric burner or a power burner. Its gas burner head is axially aligned with the conduit's exterior inlet end and spaced a short distance from this inlet. The spacing between the burner head and the conduit inlet controls the dilution air which is required to regulate the temperature of the hot air according to the oven's function such as heating food.
