STARTING UP AND REGULATION
• Make sure that the mains voltage corresponds to the manufactu-
rer's requirements and that all electrical connections made at the
installation site are effected properly as illustrated in our wiring dia -
gram.
• 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.
• 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.
• Make sure that the combustion head is long enough to enter the
furnace following the measure specified by the boiler manufacturer.
• Bleed out the air contained in the gas piping, with due precautions
and with doors and windows open.
• Open the union on the pipe near the burner and then open slightly
the gas shut-off cocks.
When the characteristic odour of gas can be smelled, close the cut-off
cock.
• Wait the time necessary for the gas in the room to disperse outside.
Re-connect the burner to the gas pipeline.

• Install a pressure gauge with adequate scale on the pressure outlet
of the gas pressure switch.
• With the switch (1) on the mimic panel switched to “O” and the
main switch turned on, manually close the remote control switch
and check that the motor revolves in the correct direction. If neces-
sary, exchange the position of the two cables in the line that feeds
the motor in order to reverse the direction of revolution.
• Now switch on the main switch. This powers on the control devi -
ce, and the programmer turns on the burner as described in the
chapter "Operation description". For burner adjustment, refer to the
instructions for the electronic cam supplied.
• After having adjusted the “minimum”, (200) turn the burner gra -
dually to maximum, by using the controls on the electronic cam
keyboard.
• Check combustion using the appropriate instrument at all interme -
diate points on the modulation route (from 200 to 999), checking
the gas flow rate by reading the meter.
• Now check the proper automatic operation of modulation. This en -
sures that the equipment receives the signal from the electronic
modulation regulator, if the burner is the modulating model, or from
the second stage thermostat or pressure switch, if it is a two stage
progressive burner.
The air pressure switch stops the equipment operation if air pressure
is not at the expected value.
The pressure switch must therefore be adjusted so that it is triggered
to close the NO (normally open) contact when the air pressure in the
burner reaches a particular value.
The connection circuit of the pressure switch is self-controlling so that
the NC contact (normally closed) which is meant to be closed at rest
(with the fan stopped and consequent lack of air pressure in the bur -
ner), must actually be in this condition. If it does not, the control box is
not switched on (the burner does not start).
Specifically, if the NO contact is not closed (normally open) as it
should be during working (this may be due to insufficient air pressu -
re), the equipment carries out its working cycle but does not switch on
the ignition transformer and does not open the gas pilot light valve so
the burner shuts down.
