2.1 General
2.2
The model BT400-46 heater is a fully enclosed, portable, two wheel, trailer mounted unit,
intended for use in ground heating maintenance shelters, portable hangers, aircraft engines
and
fuselages, and other similar enclosures.
2.3 Power Unit
2.4
The model BT400-46 heater is supplied with a variety of diesel engines. A drive coupling is
attached to the drive shaft of the engine and is attached to a driven coupling by way of a flexible
rubber sleeve. The driven coupling drives the heater fan through a pulley, a V-belt drives the fuel
pump.
2.5 Fuel System
2.6
The fuel system supplies a variety of fuel to the heater and the engine. Fuel is drawn from a
removable 35 gallon fuel tank through an automotive type fuel filter
(see figure 2-1)
by a belt-
driven fuel pump. Fuel flows through the nozzle contained in a holder with Inlet and bypass fuel
lines. As the fuel leaves the nozzle it is atomized and ignited by the igniter plug. Fuel is also
bypassed from nozzle, through a check valve, to the temperature selector valve on the control
panel. The check valve prevents a reverse flow.
