•
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.
• 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) bring the burner to the
maximum, using the controls on the electronic cam keyboard.
•
We recommend that you check the 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, using an appropriate instrument, that the
percentage of carbon monoxide (CO) present in the fumes does
not exceed the limit set by the regulations in force 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.
•
Check combustion using the appropriate instrument at all
intermediate 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 “AUTOMATIC” position.
With this setting modulation will start only by using the automatic
control of the boiler probe.
DANGER / CAUTION
The burner must not operate below the specified minimum flow
rate to prevent damage to the components of the combustion
head.
FLAME SENSOR
Verify the flame detector operation as follows:
•
extract the photocell from its seat;
•
Start up the burner;
•
The control box will complete the control cycle and after two
seconds will lock the burner due to the lack of ignition flame;
•
switch off the burner;
•
reposition the photocell;
•
This test should be carried out with the burner already on; the
apparatus should lock out immediately when the wire from the
ionisation electrode is disconnected.
•
Check for the efficiency of the thermostats or boiler pressure
switches (they should shut down the burner when triggered).
AIR PRESSURE SWITCH
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 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 valves and so
the burner “locks-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”.
Release the burner by pushing the appropriate button and readjust
the pressure switch to a sufficient value to detect the existing air
pressure during the pre-ventilation phase of the first stage.
Air pressure sampling point is downstream the air damper.
