NATURAL GAS IGNITION AND REGULATION
ADJUSTING POWER UPON FIRST START-UP
• If fitted, open the safety valve flow rate regulator fully.
• Now, turn the switch -1 on. This powers on the control box and
the programmer turns on the burner as described in chapter :
"OPERATION DESCRIPTION".
• During preventilation, make sure that the air pressure control
switch changes its status (from the closed position without pressure
measurement to the closed position with pressure measurement).
• If the air pressure switch does not detect sufficient pressure, the
ignition transformer is not switched on, nor are the gas valves, and
so the equipment is stopped in “lock-out” mode (warning light 7).
• On first switching on repeated “lock-outs” may occur due to the
following reasons:
- The bleeding-out of air from the gas piping was not performed
correctly and so there is not enough gas to provide a stable
flame.
- The “lock-out” with flame present may be caused by its
instability in the ionisation area, due to an incorrect air/gas
ratio.
- Correct the air flow rate supplied in the first stage, using the
screw(s) -11, near the bearing -12.
In clockwise rotation the air flow increases
In anticlockwise rotation the air flow decreases
SECOND STAGE POWER REGULATION.
• After adjusting the regulation for the first ignition, turn off the burner
and close the electrical circuit commanding inclusion of the second
stage. Set the switch on the printed circuit to the second stage
position.
• Check that the electric servomotor second stage gas flow rate
regulation cam is positioned at 130°.
• Activate the burner again closing the main switch -1 on the synoptic
panel. The burner turns on and goes automatically to second stage.
With the aid of appropriate instruments, attend to the regulation
of the air and gas flow according to the procedures subsequently
described:
- To regulate the gas flow operate the valve pressure regulator.
Consult the instructions related to the single stage gas valve
model installed. Avoid keeping the burner running if the heating
capacity is greater than the maximum amount allowed for the
boiler, to avoid damaging it.
• Check the combustion parameters with appropriate instruments
(CO2 MAX=10% O2 MIN= 3% CO MAX=0.1%)
FIRST STAGE POWER REGULATION.
After regulation of the burner in the second stage, return the burner
to the first stage. Set the switch on the printed circuit to the first stage
position by disabling the 4-pole green connector, without changing
the adjustment of the gas valve already performed in previous step.
• Set the first stage gas flow rate to the needed value, as described
above.
• If necessary, correct the combustion air supply adjusting the
screw/s (12) as described previously.
• Check the combustion parameters in the 1st stage with appropriate
instruments (CO2 MAX=10% O2 MIN= 3% CO MAX=0.1%)
• The air pressure switch prevents the opening of the gas valves
if the air pressure is not the foreseen one. The pressure switch
must therefore be adjusted to intervene closing the contact when
the air pressure in the burner reaches a sufficient 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 the gas valves do not open,
consequently the burner “locks-out”. To ensure correct operation of
the air pressure switch you must, with burner lit and in first stage,
increase its regulation value until the burner triggers after which
it must immediately “lock out”. Release the burner by pushing
the appropriate button -9 and readjust the pressure switch to a
sufficient value to detect the existing air pressure during the pre-
ventilation phase of the first stage.
