A gaseous fuel burner assembly for heating a space particularly an oven of a domestic cooking appliance comprises a gaseous fuel burner separated from the space by a baffle plate, and, also separated from the space by the baffle plate, a fan for withdrawing air from the space via an aperture or apertures in the plate and returning that air to the space via an exit or exits adjacent the edge of the plate, the or each aperture being so located that, during its passage from the aperture or apertures to the exit or exits, the air passes close to the burner. The fan may also draw in air from a plenum chamber behind the oven. The burner may be of the duplex variety and may have two independently controllable burner heads.

A gaseous fuel burner assembly for heating a space defined in part by walls extending transversely from an end wall; comprising a baffle supported within said space to permit airflow at its periphery between said baffle and said transversely extending wails; said baffle having at least one aperture

A gaseous fuel burner assembly for heating a space defined in part by walls extending transversely from an end wall; comprising a baffle supported within said space to permit airflow at its periphery between said baffle and said transversely extending wails; said baffle having at least one aperture therein; a gaseous fuel burner including a burner head supported between said end wall and said baffle to confront a central area of the baffle, a motor having a rotor shaft drivably coupled with said burner head; said rotor shaft providing a gaseous fuel supply conduit communicating with said burner head; and fan blades located around the burner head and coupled with said rotor shaft for rotation to withdraw air from the space to be heated via said at least one aperture in the baffle and to return that air between the periphery of the baffle and said transversely extending walls to the space to be heated.
