MODERN BURNER UNIT (MBU)
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS (Refer to Figure 1-2)
Frame - The 3/4 inch square aluminum stock frame(1) includes lifting handles (2), and base plate (3).
Reflective Heat Shield and High Temperature Insulation - The stainless steel reflective heat shield (4) directs
radiant heat upward, secures the insulation (5) in the burner well (6), and contains food spills during MBU
operation. The insulation protects components of the MBU from combustion heat.
Infrared Burner Assembly . - The infrared burner assembly (7) projects through the burner well (6), the high
temperature insulation (5) and the reflective heat shield (4).
Fuel Delivery Block Assembly. The Fuel Delivery Block assembly (8) controls the fuel/air mixture which is
provided to the burner tube assembly.
Control Panel. - The hinged control panel (9) opens for access to subassemblies. The control panel includes
four pushbutton controls, six indicators, and an hour meter.
Power Receptacle. - The power receptacle (10) is mounted at an angle to facilitate easy connection of the 24 V
DC branch cable.
Fuel Tank. - The two gallon fuel tank (11) is welded to the frame (1) and contains fuel for combustion. A vent valve
assembly (12) monitors fuel level. The fuel regulator (13) maintains zero pressure fuel for delivery to the fuel nozzle
during operation and contains a replaceable fuel filter (14). The fuel tank has a threaded plug (15) for manually
filling the fuel tank when the MBU is removed from the appliance.
Fuel Supply QD Nipple. The Fuel Supply QD Nipple (16) facilitates the connection off the fuel line, and the
flow of fuel into and out of the tank. It is also used when draining the tank of fuel.
Air Compressor. - The air compressor (17), draws air through the air intake filter, which is part of the fuel
delivery block assembly (8). The compressor also draws fuel through the QD nipple (16) during refueling.
