FIRST FILLING UP OF
PIPELINES
After making sure that protective
plastic caps inside the pump fi ttings
have been removed, proceed as
follows :
1) Set the burner switch on “0”.This
operation prevents automatic
connection of the burner.
2) With a three-phase burner make
sure that the motor rotates
counter-clockwise, looking at
the burner from the pump end.
The direction of rotation can be
determined by observing the
direction of rotation of the fan
through the port-hole on rear
of the fan scroll. To start the
motor, close the remote control
switch manually (pressing
on the mobile part) for a few
seconds and watch the direction
of the rotation of the fan. Of
it is necessary to reserve the
direction of rotation, invert two
phases on line input terminals
counter motor K1
Remark :
To positively determine the
direction of rotation, wait until the
fan turns very slowly because it
is quite possible to misinterpret
direction of rotation.
3) Disconnected, if already
connected, the flexible pipes
from both suction and return
lines.
4) Dip the end of the suction fl exible
pipe into a vessel containing
either lubrification oil or fuel
oil (do not use low viscosity
products such as gas-oil, light
oil, kerosene. etc).
5) Now press on the mobile part of
the motor remote control switch
to start up the motor and the
pump. Wait until the pump has
sucked in an amount of lubrifi cant
equal 1 or 2 glasses, then stop.
This operation will prevent the
pump from operating dry and will
increase the suction power.
Remarks:
Pump operating at 2800
r.p.m. must not work dry otherwise
they will jam (seizure) within a very
short time.
6) Now connect the fl exible pipes
to the suction line and open all
the gate valves fi tted on this line
and any other similar fuel cut-off
device.
7) Now press again on the mobile
part of the motor remote control
switch to start up the pump which
will suck fuel from the tank. When
fuel is seen coming out of the
return line (not yet connected),
stop.
Remarks:
If the pipe is long, it may be necessary
to bleed the air out through the
cap; if the pump is not fi tted with a
breather cap, remove the cap from
the pressure test point.
8) Connect the return fl exible pipe
to the return line and open the
valves fi tted in this pipe. Now the
burner is ready for lighting up.
STARTING UP AND
REGULATION
(see page 39-40-
41)
Before starting up the burner make
sure that :
a) Feeding line connections to
thermostats or pressure switches
are made exactly according to
electric diagram of the control
box.
b) Check if there is fuel in the tank
and water in the boiler.
c) All the gate valves fi tted on the
fuel oil suction and return pipes
should be open; the same thing
applies to any other fuel cut-off
device.
d) Make sure that discharge of
combustion products takes place
freely (boiler and chimney gate
valves open).
e) Make sure that burner head
project into the combustion
project into the combustion
chamber according to the
chamber according to the
manufacturer ’s directives.
For compliance with this
requirement, the burner is
equipped with a boiler mounting
fl ange, which slides in respect to
the combustion head.
f) The nozzles fitted on the
burner should match the boiler
capacity but, if necessary,
replace them with others.
Under no circumstances should
the amount of delivered fuel
be higher than the maximum
amount required by the boiler
and the max. amount permitted
for the burner. To start the burner
proceed as follows:
Note:
The burners in TBL version
are provided with switch to change
from 1st to 2nd stage.
1) 1) Avoid working with the second
fl ame: position the 1st and 2nd
stage switch on the printed
circuit at its 1st stage position
for burners.
2) Slightly open the air shutter and
let in an amount of air deemed
to be necessary for burner
operation with the 1st fl ame and
fi x it in this position; set the air
control device in an intermediate
position on the combustion head
(see the chapter “Air control on
the combustion head”).
3) Close the isolating switch and
control box switch.
4) The small motor of the cyclic relay
which will start to rotate causing
the connection of the burner
component devices according to
the preset program. The burner
will start operation as described
in the Chapter “Description of
Operation”.
5) When the burner operates with
the 1st fl ame, adjust the amount
of air necessary,for an effi cient
combustion by following the
previous description under n. 2.It
is better if the amount of air for
the 1st fl ame is slightly reduced
in order to ensure a perfect
ignition also in the most critical
conditions.
6) After adjusting the amount of air
for the 1st fl ame, stop the burner
by cutting off the current from
isolating switch, connect the
terminals on the terminal board
of the 2nd flame thermostat
among them and settle the 1st
and 2nd stage switch in 2nd
stage position.
7) Adjust the screw which restricts
the stroke of the hydraulic piston
controlling the air shutter of
the 2nd fl ame; unscrew it that
amount which is deemed to be
necessary to burning fuel.
