A gas burner including a burner body having a lower housing, an inlet conduit and a combustion surface element attached to the lower housing. A diffuser/reflector positioned within the body encourages even distribution and mixing of a combustible gas/air mixture. The diffuser/reflector is preferably of a sheet metal construction and includes a plurality of stamped openings with each of these openings having an overhanging guide plate. The combustion surface element includes a plurality of integrally formed rigidizing ribs and is made from a high temperature steel alloy wire cloth. The inlet conduit is secured directly or indirectly to an access door/bulkhead that is used to close off an access opening formed in a water heater wall through which the burner is installed. In one construction, an air scoop shrouds the inlet conduit and at least partially defines a flow path of primary air, substantially isolated from the combustion chamber.
A gas burner comprising:
A gas burner comprising:
A diffuser/reflector for use in a gas burner of the type that includes a burner body having a sidewall and a steel alloy screen element attached to said burner body that defines a combustion surface and an inlet conduit for delivering a gas/air mixture to a region below said screen element, said diffuser/reflector comprising a structure including a first plurality of openings, each opening of said plurality including a transversely extending overhanging element, said elements being arranged to reflect heat away from said lower housing and to encourage gas/air mixing as said gas/air mixture travels from said lower housing to said combustion surface, said overhanging elements arranged to direct the flow of said gas/air mixture in a transverse direction away from an axis of said inlet conduit, and towards said sidewall of said burner body said structure further including another plurality of openings located in an another region of said structure, said other plurality of openings forming part of an unobstructed flow path for said gas/air mixture to said combustion surface.
