Radiant heater

摘要

A radiant heater which burns LPG fuel is provided with an improved burner assembly and an improved support assembly for mounting the heater on a propane tank. The heater includes a frame, a reflector mounted on the frame, and a burner assembly which is removably mounted within the reflector and the frame. The burner assembly includes a burner tube having an inlet end mounted within the frame and an outlet end positioned within the reflector. A generally dome-shaped screen is mounted on the outlet end of the burner tube, and a generally circular screen is attached to the dome-shaped screen substantially in alignment with the burner tube. A burner pan is mounted on the burner tube and surrounds the dome-shaped screen, and an outer screen extends across the burner pan. A thermocouple sensor and/or an igniter electrode on the frame extends through one or more openings in the burner pan. A single fastener prevents removal of the burner assembly from the frame, and when the fastener is disengaged from the burner assembly, the burner assembly can be removed and replaced. The support assembly includes a rigid support member which extends downwardly from the frame and is releasably engageable with an LPG tank. In one embodiment the support member is a fuel conduit which is connectable to a fuel valve on the LPG tank. A support bracket is adjustably mounted on the fuel conduit and is engageable with the top of the LPG tank.
