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.
A burner assembly for a heater comprising a burner tube having a rear inlet end and a forward outlet end and a fuel passage therethrough, a burner head mounted on the outlet end of the burner tube, the burner head including a first screen which is spaced forwardly from the outlet end of the burner tube, the first screen having a central portion which is aligned with the fuel passage of the burner tube and an outer portion which extends laterally outwardly beyond the burner tube, a second screen which is smaller than the first screen and which is attached to the central portion of the first screen and which extends over at least a portion of the central portion of the first screen, a burner pan having an outer periphery and a central opening through which the burner tube extends, and a third screen enclosing the periphery of the burner pan and spaced in front of the first screen.
In a heater having a frame, a burner assembly mounted on the frame, a fuel supply means mounted on the frame for supplying fuel to the burner assembly, the fuel supply means having a fuel outlet, the improvement comprising
A heater adapted to be removably secured to an LPG tank which includes a generally dome-shaped top and an outlet valve which is mounted on the top, the heater including a heater assembly having a top and a bottom and a support assembly extending downwardly from the heater assembly for supporting the heater assembly on an LPG tank, the support assembly comprising:
A heater adapted to be removably secured to an LPG tank which includes a generally dome-shaped top and an outlet valve which is mounted on the top, and a collar which extends around at least a portion of the outlet valve, the heater including a heater assembly having a top and a bottom and a support assembly extending downwardly from the heater assembly for supporting the heater assembly on a propane tank, the support assembly comprising:
