Abstract:
1. A method for operating a wood fired appliance to produce heat, the method comprising: exhausting gas from a combustion chamber, past a bottom surface of a baffle disposed in a raised open position, past an open first opening in a top wall, and out a flue; loading wood through the first opening, past the raised baffle, and into the combustion chamber; automatically moving the baffle to a lowered closed position from the raised open position in response to a top loading door being moved to a closed position to close the opening in the top wall wherein the top loading door in the closed position engages an upper leg of a cam to rotate a lower leg of the cam, which rotated lower leg engages an upper portion of the baffle in the raised open position to cause the baffle to fall by itself under the force of gravity to the lowered position from the raised open position; automatically inhibiting the baffle from being maintained in the raised opened position by the rotated lower leg of the cam when the top loading door is disposed in the closed position; and exhausting gas from the combustion chamber between a top surface of the baffle disposed in the lowered closed position and a bottom surface of the top loading door disposed in the closed position, and out the flue.
