STARTING UP AND REGULATION
• Check that thee voltage on the mains meets the manufacturer
requirements and that all electrical connections made at the in-
stallation site are performed properly as illustrated in our wiring
diagram.
• Check that the discharge of combustion products through the
boiler gate and flue gate take places freely.
• 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 devi-
ces.
• Bleed out the air contained in the gas piping, with due precau-
tions and with doors and windows open.
• Open the union on the pipe near the burner and then open the
shut-off valves a little.
• Wait the time necessary for the gas in the room to disperse
outside. Re-connect the burner to the gas pipeline.
• Make sure that the combustion head is long enough to enter
the furnace following the measure specified by the boiler ma -
nufacturer.
• 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 on the burner panel at the position “0” and the
main switch on, check, closing the contactor manually, that the
motor rotates in the right direction. If necessary, swap the two
power cables for the motor around to change the direction of
rotation.
• If using the inverter, see the specific instructions in the quick
guide.
• Turn on (position I) the switch (1) on the control panel to power
the equipment and close the thermostat line and turning the
selector (2) in the "closed" position.
• If thermostats or pressure switches (safety and boiler) are clo-
sed as well, the operating cycle will start.
• The equipment turns on.
• For the regulation of the burner, see “RAPID GUIDE TO
PROGRAMMING” and the specific instruction manual for the
electronic cam.
• After setting the minimum load (200 digits), bring the burner up
to the maximum using the controls on the electronic cam keypad
and adjust all the points (from 200 digits to 999 digits) following
the regulation chart (see the electronic cam instructions in the
attached manual).
• Check combustion using the appropriate instrument at all in-
termediate points on the modulation route (from minimum to
maximum load), checking also the gas flow rate reading the
meter.Now, check for the efficiency of automatic modulation
operation by switching the ETAMATIC apparatus to the “AUTO-
MATIC” position. With this setting modulation will start only by
using the automatic control of the boiler probe.
The air pressure switch stops the equipment operation if air pres-
sure is not at the expected value.
The pressure switch must therefore be adjusted so that it is trigge-
red to close the NO contact (normally open) when the air pressure
in the burner reaches a particular value.
If the air pressure switch does not detect a pressure greater than
that calibrated, the equipment runs through its cycle but does not
switch on the ignition transformer and does not open the gas val-
ves and so the burner “locks-out”.
To ensure the air pressure switch correct operation, with burner at
the minimum output, increase the adjustment value until reaching
the triggering value which must be followed by the immediate bur-
ner lock-out.
To ensure correct operation of the air pressure switch you must,
with burner on and in 1st stage, increase its regulation value until
the burner triggers and then it immediately “locks-out”.
