AUXILIARY PUMP
In some cases (excessive distance or difference in level) it is
necessary to install a “loop-type” supply system with an auxiliary
pump, which dispenses with the connection of the burner pump
directly to the tank.
In this case the auxiliary pump can be put into operation when the
burner is started up and cut-off when the latter stops.
The electric wiring of the auxiliary pump is made by connecting
the coil (230 V) which controls the pump remote control switch
to terminals “N” (equipment terminal board) and 6 of the control
equipment.
It is important to comply strictly with the previsions set forth here
below:
- The auxiliary pump should be installed as near as possible to
the fuel to be sucked.
- Its head should meet the requirements of subject system.
- We recommend a delivery rate equal to at least that of the
burner pump.
- Connection pipes should be sized to cope with the delivery
rate of the auxiliary pump.
- Always avoid to electrically connect the auxiliary pump directly
to the remote control switch of the burner motor.

BURNER ASSEMNLY
A) Adjust the position of connector flange 5 by loosening the
screws 6 so that the combustion head penetrates the
advised amount intothe combustion chamber as recommen
ded by the generator’s manufacturer.
B) Position the seal insulation 3 on the tube unit inserting cord
2 between flange and seal.
C) Fasten the burner 4 to the boiler 1 by means of the stud
bolts, washers and the nuts provided 7.
Note:Competely seal the space between the tube unit of the
burner and the hole in the refractory panel using suitable ma-
terials to do so.
