Abstract

A forced air, fuel burning heater is provided which includes a relatively large damper plate slideably mounted immediately below the top wall of the heater, to thereby insulate the top wall from the heat of combustion and thereby reduce the temperature and thus the tendency of the top wall to warp from excessive heat. The damper plate preferably includes a rearward edge which is doubled upon itself to further insulate the edge of the flue opening in the top wall from heat, where warpage commonly occurs. The disclosed heater also includes a separate blower assembly which may be selectively mounted on either side of the combustion chamber with equally effective air circulation, and the hearth plate includes an upwardly inclined forward edge portion for reflecting radiant heat back toward the heater and thus reducing the temperature of the adjacent floor surface.

Claims5

Dependent claims

A fuel burning heater characterized as having a relatively low temperature on the top wall thereof so as to minimize warpage and deterioration of such wall, and comprising

a front wall, a back wall, opposite side walls, a bottom wall, and a top wall collectively defining an enclosed combustion chamber,
an access opening in said front wall to permit access to said combustion chamber,
a flue opening in said top wall adjacent said back wall for communicating with a flue or the like,
a relatively flat damper plate having an overall area comparable to at least a substantial portion of that part of the area of said top wall within said combustion chamber forwardly of said flue opening, and means slideably mounting said damper plate within said combustion chamber immediately below and parallel to said top wall, and for movement between a rearward position underlying and substantially closing said flue opening and a forward position wherein the damper plate is spaced forwardly of said flue opening and underlies a substantial portion of that part of the area of the top wall forwardly of said flue opening to thereby insulate the top wall from the heat of combustion within said combustion chamber, said mounting means including a rod fixed to said damper plate and extending forwardly through said front wall, and handle means fixed to said rod forwardly of said front wall.
