STARTING UP AND REGULATION
Before starting up, make sure that:
•
Check that the nozzles fitted on the burner are suitable for the
boiler capacity. If necessary, replace them with suitable ones.
In no case should the quantity of fuel delivered exceed the
maximum amount required by the boiler and the maximum
amount allowed for the burner.
• Make sure that the mains voltage corresponds to the
manufacturer's requirements and that all electrical connections
made at the installation site are effected properly as illustrated
in our wiring diagram.
•
Make sure that the combustion products may be freely vented
through the boiler and flue dampers.
•
Check that there is water in the boiler and that the gate valves
of the system are open.
• Make sure that there is fuel in the tank.
•
Check that all the gate valves fitted on the fuel suction and
return pipes are open; the same applies to any other fuel shut-
off devices.
• Avoid second stage operation. Set the switch on the electrical
panel to the first stage position. If the burner does not have
the first and second stage switch, disconnect the thermostat to
avoid activating the second stage, if installed.
• Slightly open the air regulator and let in an amount of air
deemed necessary for burner operation with the 1st stage and
lock it in this position.
•
Set the air adjustment device on the combustion head in an
intermediate position.(refer to the chapter Air regulation on the
combustion head).
• Turn on the main switch and the one on the control panel, (S1),
if provided.
•
The programmer starts executing the preset program, activating
the devices comprising the burner.
•
The equipment will start as described in the chapter
“OPERATION DESCRIPTION”.
•
With the burner operating in the first stage, adjust now the
amount of air necessary for ensuring efficient combustion.
•
We recommend keeping the air quantity at a low level when
working in the first stage output to ensure perfect ignition even
in the most difficult conditions.
•
After adjusting the first stage air, disconnecting the current
from the main switch, close the electric circuit commanding the
second stage activation and move the switch on the electrical
panel to second stage.
•
If the electrical panel does not have the first and second stage
switch, connect the terminals of the 2nd stage thermostat with
each other on the boiler terminal block.
• Working on the screw limiting pin stroke for the models with
hydraulic jack (0002935420), or on the second stage air
regulation cam for the models with servomotor (0002935210),
set the second stage air damper opening at the position
considered suitable for the desired fuel delivery.
•
Now the equipment is activated again and will automatically
switch to the second stage according to the program set by the
programmer.
•
Regulate the air quantity to ensure a good combustion.
•
Check combustion with special instruments.
•
If the appropriate instruments are not available, judgement can
be based on the colour of the flame.
•
Regulate to obtain a light orange flame avoiding a red flame
with smoke, or a white flame with air excess.
•
Air regulation should be performed to allow a certain amount of
carbon dioxide (CO2) in the fumes, which may vary from a min.
of 10% to a max. of 13% with a fume index not exceeding 6 of
the Bacharach scale.
CAUTION / WARNINGS
With a hydraulic jack,
When switching on the burner for the first time, shut downs
may be experienced during the transition from the first to
the second stage, due to the presence of air in the jack
circuit.
Slightly loosen the nut blocking the jack pipe, carry out a
few operating cycles until there is fuel discharge from jack
connection nut.
Tighten the nut when the operation is finished.
