Major Components
1.4.1 Shell
The D-1000B Heater features a two-piece, molded polymer composite outer body that is rust-resistant and shock proof.
The upper cover quickly detaches for service to the combustion chamber, electric motor, or fuel pump assembly by
removing four pins as shown in Figure 5-1.
1.4.2 Fuel Tank
The fuel tank is made of steel and is corrosion proof. The fuel tank has an internal fuel level indicator gauge cap and a
drain plug located underneath the fuel tank. The fuel tank capacity is 10.8 US Gallons (40.8 Liters) Use JP8 or Diesel fuel
when filling the fuel tank.
1.4.3 Combustion Chamber
The D-1000B has a dual combustion chamber made of stainless steel and is fully welded to provide clean warm air. The
heater is equipped with fifteen seconds pre-ventilation cycle to “clean” the combustion chamber. After switching the
heater off, a post ventilation time is electronically set by a control flame box to lower the combustion chamber
temperature. This
free
heat is blown into the area.
1.4.4 Burner Head
The burner head contains the fuel nozzle, dual electrodes, ignition cables and a flame detector.
1.4.5 Electric Motor
The electric motor drives the fuel pump assembly and a fan which propels additional air into the combustion chamber.
1.4.6 Control System
The D-1000B heater has an electronically control system located in a watertight panel mounted on the side of the unit.
The control panel consists of a 3-positioned switch for power, normal operation and thermostat operation, an outlet to
connect the remote thermostat / CO detector and a reset button. The control system utilizes a safety shut-off switch if
flame is not detected, a high temperature switch if ducts become blocked and a safety shut-off switch upon detecting
100ppm of Carbon Monoxide content.
