Attention, important hints to the after-cooling phase
The air supply fan continues running to cool down the
combustion chamber and then stops later.
The fan can start several times before final switching off.
Unit Shut Down
Heating with room thermostat (accessories)
The unit runs fully automatically and depending on tem-
peratures.

The thermostat sensor may not be
exposed directly to the hot air cur-
rent and not fixed directly on a cold
surface.

ture on the room thermostat
5. Put the operating switch into position
“1” (on).

Setting the pump pressure
The pump pressure can only be set if a manometer is
connected to the connection
P
. The pump pressure is
changed by turning the pressure setting screw
A
:
clockwise: increase the pressure.
counter clockwise: reduce the pressure.
The required pump pressure is determined according to
the heating capacity (please refer to unit type plate) and
to the nozzle size. The pressure setting screw "A" is to
be secured with the counter nut "B" after having set the
pressure.
Fuel Pump
The standard type of the pump runs in a system of
1 pipe. The required fuel is sucked in through the suction
line "S".
For the first starting and after having emptied the fuel
tank, the fuel system is deaerated through the burner
nozzle.
For this purpose the unit is switched on. After a possible
switch off through failure, the unit is restarted after hav-
ing released the automatic burner relay (take care of
waiting time).
If, after the 3rd start of the unit there is another switch
off through faults, the fuel filters should be checked to
make sure that they are free from pollutions and that
they are tight.
G
Perfect fuel quality is an absolute necessity for the
lubrication of the pump drive.
Suction of water residues should never take place
and, in the case of setting, suction should not take
place of warping fine dusts (e.g. cement etc.).
G
Never let the pump run without feeding fuel for a
longer period. Make sure not to leave a unit with
dry run pump unattended for a longer time.
