  • Down-tube assembly (9). A capped down tube which is positioned on the up-tube (20) and removable through the lid assembly (7). A super-heater ring is located on the exterior for heat transfer. During operation, fuel flows into the up-tube (20), where its level is gravity-maintained with the fuel flow control valve (16).
  • Fuel vaporizes due to combustion heat and fuel vapor is expelled from the up-tube (20), down through the down tube and into the burner shell (18) where it ignites. The down-tube (9) and up-tube (20) are cleaned with the reaming tool (21), which is kept inside the heater body during storage (15). The reaming tool (21) should be stored in an accessible yet protected location when not in use.
