FIRST FILLING UP OF PIPELINES

After making sure that protective plastic caps inside the pump fittings
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
E
until the fan turns very slowly because it is quite possible to
N
misinterpret direction of rotation.
3) Disconnected, if already connected, the flexible pipes from both
G
suction and return lines.
4) Dip the end of the suction flexible pipe into a vessel containing
L
either lubrification oil or fuel oil (do not use low viscosity
I
products such as gas-oil, light oil, kerosene. etc).
5) Now press on the mobile part of the motor remote control switch
S
to start up the motor and the pump. Wait until the pump has
sucked in an amount of lubrificant equal 1 or 2 glasses, then
H
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 flexible pipes to the suction line and open
all the gate valves fitted 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 fitted with a breather cap,
remove the cap from the pressure test point.
8) Connect the return flexible pipe to the return line and open the
valves fitted in this pipe. Now the burner is ready for lighting
up.

STARTING UP AND REGULATION

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 fitted 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
chamber according to the manufacturer's directives.
For compliance with this requirement, the burner is equipped
with a boiler mounting flange, 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) Avoid working with the second flame: 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 flame and fix
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 flame, adjust the amount
of air necessary,for an efficient combustion by following the
previous description under n. 2.It is better if the amount of air
for the 1st flame 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 flame, 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 flame; unscrew it that
amount which is deemed to be necessary to burning fuel.
Remarks: Before turning the adjusting screw, loosen the lock nut
and after completing the adjustment, tighten it up again.
8) Now connect the burner again; it will start and automatically
switch to the 2nd flame according to the present program.
9) With the burner operating with the 2nd flame, adjust the
amount of air necessary to ensure an efficient combustion with
the screw mentioned under item 7. Combustion test should be
made using appropriate instruments. Make the regulation so as
to obtain a certain amount of carbon dioxide (CO
varying from min. 10% to max. 13% with a smoke number not
exceeding 2 (Bacharach scale).
