1. A liquid fuel burning appliance comprising:
- a burner assembly including a burner for providing a flame and a generator in heat exchange relationship with the burner for vaporizing liquid fuel within the generator,a fuel tank separate from the burner for holding liquid fuel,a fuel valve on the fuel tank,means for pressurizing the fuel tank,a fuel tube connecting the fuel valve and the burner assembly for conveying pressurized liquid fuel to the burner assembly, the fuel tube having an upstream end which is connected to the fuel valve, a downstream end which is connected to the burner assembly, and an internal bore through which the fuel flows, andflow-restricting means positioned within the bore of the fuel tube adjacent the downstream end of the fuel tube for restricting the flow of fuel through the fuel tube, for reducing the pressure of the pressurized fuel downstream of the downstream end of the fuel tube, and for reducing surge of liquid fuel when the valve is open.

Abstract
A burner appliance includes a burner assembly, a separate fuel tank, and a tube connecting the fuel tank and the burner assembly. A restrictor rod is positioned within the tube for minimizing fuel surge, enhancing generation of vaporized fuel, and reducing flame pulsation. The restrictor rod is part of a sealing valve which provides secondary shut-off of fuel in the event that the tube is disconnected from the burner assembly.
