6-COMMISSIONING AND SETTINGS
6.1 Checks before commissioning
1-
Before starting the commissioning and powering the device, check the following things :
-
The connection of air combustion and fumes must be perfectly sealed.
-
Ensure the perfect tightness of the gas circuit till the heater.
-
The section of gas pipe line is correct according the gas type and pressure.
-
The nature of gas and the pressure supplied according the heater settings.
-
The ground connection of the heater, the phase-neutral polarity and the pilot wire connection.
-
The protective film on the heater has been removed.
-
The distances around the heater have been respected.
2- Check the electricity supply, between 210V et 230V.
Be careful with the phase-neutral polarity. In case of reversal, the mistake is displayed on the control board
of the heater. (in that case, reverse blue and brown wires on the power supply.
If the neutral is impedance earthed (more than 20 volts between neutral and ground), provide a non-
polarized control panel or a isolating transformer on the heater.
3– Check that the type of gas and the pressure supply match qith the heater.
The maximum inlet pressure from gas valve cannot exceed 50 mbar. Refer to the chapter « GAS
CONNECTION ».
6.2 Commissioning
The first commissioning must be realized by a qualified technician.
To commission the heater, raise the set point temperature of the ambient thermostat.
The heaters are setup and tested in factory. They do not required any adjustment for altitudes located
between the sea level and 500 meters. It is still necessary to realize combustion analysis at the
commissioning.
STOP
When the heater is power up, the display shows the heater state.
The messages are the following:
STOP
VENTILATION
PRE-VENTILATION
MNI POWER
MAXI POWER
ERROR OR DEF
In case of default, refer to the chapter « Troubleshooting »
PH/N INVERSION
ERROR
A polarity reversal is indicated by the display.
It is necessary to cut-off the power supply of the heater and
reverse the phase and neutral of the main power supply of the
heater. When the operation is complete, the message on the
display will disappear.
