STARTING UP AND REGULATION

• 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.
• 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.

• Apply a pressure gauge of appropriate scale to the pressure
intake on the gas pressure switch. If the foreseen amount of
pressure allows it, it is better to use a water column instrument.
Do not use dial instruments for average pressures.
• 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
necessary, 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
device, 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
gradually to maximum, by using the controls on the electronic
cam keyboard.
• We recommend that you check combustion using the appropriate
instrument at all intermediate points on the modulation route
(from 200 to 999), checking the gas flow rate by reading the
meter.
• It is essential to check, with a suitable instrument, that the
percentage of carbon monoxide (CO) present in the fumes does
not exceed the limit set by regulations at the time of installation.
• Now check the proper automatic operation of modulation.
This ensures 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 burner), 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
pressure), 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.
