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 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 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.
5a) In the case of mono-phase power supply, switch off the master
switch and boiler and safety thermostats and then start up the
motor and ignition transformer. On inserting the solenoid expose
the photoelectic cell to a light source so that the the burner
does not “lock-out”. When the piping is filled (when fuel comes
out of the nozzle) stop the burner and put the photoelectic cell
back in its place.
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) Run the pump again as in point 5) and 5a) in the case of
monophase and three-phase burners. The pump with draw
up the fule 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 DACA 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 of the electrical panel at its 1st stage position. If the
burner does not have 1st and 2nd stage, remove any thermostat
connection to prevent insertion of 2nd flame.
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; for the adjustment of the hydraulic jack see
0002935420, for adjustment with servomotor see 0002935210.
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, if present
(see diagram 0002935510).
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 of the
electrical panel in 2nd stage position. If the electrical panel
does not have 1st and 2nd stage switch connect the terminals
of the 2nd stage thermostat on the boiler terminal block.
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 for 2nd flame for servo motor models (see
