Major Components Interaction

  1. Heater assembly. The Type II (Liquid Fuel) Heater assembly consists of a heater body base (1) and a top heater shell (2). The heater body base (1) serves as a base for the assembled heater. It houses the burner shell assembly (3) during operation. Two heater body base doors (4) are cut into the heater body base (1) at opposite positions to allow air for combustion. A support (5) to hold the fuel flow control valve bracket (6) is welded adjacent to the front heater body base door. Three evenly spaced bolt and wing nut assemblies (7) are welded to the heater body base (1). Three evenly spaced brackets (8) are welded to the top heater shell (2). The three bolt and wing nut assemblies (7) secure the top heater shell (2) to the heater body base (1) when you slide the bolts into the brackets (8) and tighten the wing nuts . When you operate the H-45 Type II (Liquid Fuel) Heater, place the top heater shell (2) onto the heater body base (1) and secure. The top heater shell (2) has one internally flanged, 9-inch (22.86-centimeter(cm)) circular cutout (9) to accommodate the lid (10), and one externally flanged 4-inch (10.16-cm) cutout (11) that serves as mounting for the stack pipe sections (12).
  2. Burner shell assembly and adapter ring. The burner shell assembly (3) fits into the heater body base (1). It consists of a rolled steel pot (13) with a high fire ring (14), a burner cap assembly (15), and a super heater assembly (16). An adapter ring (17) that engages the upper rim of the heater body base (1) is welded to the burner shell assembly (3). The high fire ring (14) is held in place by three clamps (18) that attach to the adapter ring (17) with pan head screws. Use a cleaning tool (19) to clean soot and any buildup from the inside of the up-tube and down-tube.
  3. Fuel flow control valve. The fuel flow control valve (20) mounts on the side of the heater body base (1). The fuel flow control valve (20) functions with JP-8; DF-A, DF-1, or DF-2; JP-5; kerosene; Jet A-1; Jet A; gasoline (emergency only); and JP-4 (emergency only). It has several orifices to match the various viscosities of the fuels being used. The orifices are cut to permit a maximum and minimum flow rate consistent with the safe operation of the heater.
  4. Exhaust system. The exhaust system consists of six stack-pipe sections (12) connected end to end, leading from the 4-inch (10.16-cm) externally flanged circular cutout (11) on the top heater shell (2), through the tent roof (21), and topped by a stack cap assembly (22), to which three wire ropes and guy lines (23) are attached to provide stability.
  5. Hose assemblies. The hose assemblies conduct fuel from the fuel source to the fuel flow control valve(20), from the fuel flow control valve (20) to the burner shell assembly (3), and from the fuel flow control valve (20) to the overflow area.
