4. The Technical Data
As long as no limit value is indicated, the technical data
are given at +20 0C and with ± 10 % tolerance that is
normal at the heating devices for nominal voltage.
4.1 The Electrical Elements
The control device, the engines of the burner fan and
circulation pump, magnetic valve, induction bobbin,
heater of the nozzle block, heating cartridge and the
program timer have been designed to be suited for 24
Volts. The voltage does not make any difference for the
heat constrainer, flame regulator, temperature sensor and
switches.
WARNING
The suitability of the circulation pumps to the heating
devices will be specified according to the resistances on
the cooling water side.
4.2 The Fuel
The diesel fuel recommended by the vehicle
manufacturer is suitable as fuel. Only the fuel indicated
on the factory label can be used. EL class fuel-oil (not L
class) can also be used if it complies with the quality in
the German market.
No adverse situation resulting from the admixtures is
known.
The instructions of the vehicle manufacturer related to the
admixture must be observed if the fuel will be taken from
the fuel tank of the vehicle.
In the case that the fuel will be taken from a separate fuel
tank, winter diesel fuel must be used at temperatures
under 0 0C or gas oil or gas must be added to the diesel
fuel under the condition that attention will be paid to the
mixture proportion. The utilization of substances that
provide fluidity is possible.
