Abstract: A burner assembly for a fireplace, comprising a fuel-metering plate, a fuel-delivery plenum and a dividing plate. The fuel metering plate has tines that form a combed structure in an uppermost portion of the fuel-metering plate, the combed structure extending along a long dimension of the fuel-metering plate. The fuel-delivery plenum has a fuel chamber and the fuel-delivery plenum being coupled to the fuel-metering plate such that the fuel chamber extends along the long dimension of the fuel metering plate. The dividing plate is located between the fuel-metering plate and the fuel-delivery plenum. The dividing plate has a slotted opening that extends along the long dimension of the fuel metering plate, the slotted opening being in fluid communication with individual channels between the tines and with the fuel chamber.

Abstract: One aspect provides a heating device comprising a firebox having a hearth therein and first and second heat exchange chambers, and a heat exchanging plate having a first surface and a second opposing surface. The heat exchanging plate is suspended above the hearth, such that the first surface is located between the hearth and the second surface. The heat exchanging plate has lower protrusions extending from the first surface and into the first heat exchange chamber, and upper protrusions extending from the second surface and into the second heat exchange chamber. A method of manufacturing a heating device is also disclosed.
