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
To positively determine the direction of rotation, wait until the
!
fan turns very slowly because it is quite possible to misinter-
pret direction of rotation.
3) Disconnected, if already connected, the flexible pipes from both
suction and return lines.
4) Dip the end of the suction flexible 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 lubrificant equal 1 or 2 glasses, then
stop. This operation will prevent the pump from operating dry
and will increase the suction power.
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.
: 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:

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 1
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 1
burner by cutting off the current from isolating switch, connect
the terminals on the terminal board of the 2
among them and settle the 1
position.
7) Turning the screw that limits the piston travel distance in the
case of models with hydraulic jack (see 0002935420) or use
air adjustment cam air of the 2
(see 0002935210) and set the air shutter opening in the 2
stage at a position considered suitable for the desired supply
of fuel.
8) Now connect the burner again; it will start and automatically
switch to the 2

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).
