Abstract
A pellet fuel burning heating unit having a firebox with a burner therein connected to a combustion air duct, an exhaust pipe to remove combustion gases from the firebox, a blower to provide combustion air and a pressure regulator and air splitter to divide the air flow from the blower into the combustion air duct and into the exhaust pipe. The air flow into the combustion air duct creates a positive pressure in the burner and the air flow into the exhaust pipe creates a suction of the exhaust gases in the firebox.
