A cooking grate for a grill, such as a barbecue grill, is comprised of a plurality of generally elongate rail members assembled in a nesting relationship to form a first and second cooking surface. The first cooking surface is formed by a generally flat surface on each of the rail members, the flat surfaces abutting to form a substantially smooth surface, with a plurality of elongate apertures therein through which juices produced by cooking food may flow. Each rail member has a gutter along its length which underlies approximately half of each of the apertures for catching a portion of the juices and diverting it from the heat source below. The grate may be reversed and the gutters form the second cooking surface which is similar to a conventional grate surface.

Barbecue grill grate

A barbecue grill having a cooking surface and a retractable light mounted to an upper portion of the lower grill housing and moveable between a first operable position and a second stored position. In the operable position the light is oriented to illuminate the cooking surface of the grill. In the stored position, the top surface of the light is substantially aligned with the cooking surface and the top surface of an auxiliary shelf attached to the grill. The light may also be supplied separately for retrofit on any existing grill.

A forced air, wall heater includes a heat exchanger which has a plurality of tubes. Each of the tubes include substantially parallel aligned runs and at least one return section between adjacent runs. The return section is aligned generally perpendicular with each of the plurality of runs. The heater also includes a blower positioned for blowing air directly toward the return section to maximize the mass flow rate of air over the return section. At least two of the runs are offset both laterally and in the direction of air flow with respect to each other. The ordering of tubes differs in at least two positions within the exchanger.

Wall heater with improved heat exchanger

A pulse combustion space heater and burner are disclosed. The heater has an exterior cabinet enclosing an interior housing having the burner mounted therein. The burner includes a plurality of generally flat elements which cooperate with the interior housing to provide a tortuous path for air circulated through the chamber during heat transfer. A labyrinthine air flow passageway lined with sound attenuating material is provided immediately upstream of the heater air discharge. The burner tailpipe comprises a weldment of two identical sheet metal pieces which cooperatively define a tailpipe conduit. A fuel gas inlet orifice is mounted in the wall of the mixer head to effect both regulation of the average flow rate and injection of the fuel to enhance its mixture with the air.
