2.3.1 The pre-heating of the nozzle block
The fuel going to the vaporizer nozzle will be heated with
the pre-heating of the nozzle block.
Work failures could occur at excessive low temperatures if
there is no pre-heating of the nozzle block. The heater
cartridge in the nozzle block will be activated over a
thermostat when the temperature is < 0
0
C. The heating
period depends on the temperature of the radiation
reflected in the combustion chamber and will be ended
when this is +8
0
C in the thermostat.
In the case that there is no pre-heating at the nozzle
block, this can be installed at a later time. Please refer to
the Spare Part List for the necessary parts.
2.4 The heat exchanger
The heat that will be produced with the combustion will
be transferred to the cooling water circuit at the heat
exchanger.
