Description of the Thermostart
The thermostan is a starting aid for use in low
ambient temperatures.
It
ignites and burns fuel
in the intake manifold to warm the air intake and
improve starting qualities. Thethermostart, unlike
glow plugs,
is
not exposed to the combustion heat
-
of the engine during operation and therefore pro-
vides outstanding durability, and since
its
elec-
tricity requirement is lower than that of glow
plugs, the load on the battery
is
reduced.

Terminal
a) Thermostan switch
is
set to ON. This
activates the heater coil.
b) Valve stem moves. This opens the ball
valve.
c)
Fuel flows through ball valve, and volatil-
izes because of heat from heater coil.
e)
Setting thermostart switch to OFF posi-
tion will switch off the electricity and the heat-
er will cool off. This will close the ball valve.
f)
Fuel will cease to flow. Fuel is stored in
header tank, and
is
fed to thermostart plug by
gravity.
