Operating with Gas ;
Operation of two-stage burner
Ø
Open the main gas valve, check the gas pressure from the manometer at the valve. (max.300
mbar)
Ø
Check the boiler thermostat or pressure switch settings.
Ø
Bring the operating switch on the burner panel to position 2.
Ø
Burner fan motor will be activated.
Ø
Ignition will take place at the end of pre-purge process.
Ø
3 sec. later, the gas valve will be opened and combustion will occur.
Ø
Flame control system (ionization) will start flame control.
Ø
Burner will switch to the second stage (max. capacity) according to the heat requirement.
Ø
After the boiler water heated up or the boiler pressure has risen, the burner will turn off.
Operation of a modulating burner
Ø
Open the main gas valve; check max 300 mbar gas pressure from the manometer.
Ø
Open operating switch on the burner panel.
Ø
Switch on the modulating control switch.
Ø
Switch automatic-hand switch to automatic.
Ø
Check the temperature and pressure set values from the modulating control unit.
Ø
Ignition will take place at the end of pre-purge process.
Ø
3 sec. later, the gas valve will be opened and combustion will occur.
Ø
Flame control system (ionization) will start flame control.
Ø
In modulating burner, the burner goes into max. capacity according to the signal from the
modulating control unit.
Ø
When the boiler water temperature or steam pressure increase, the modulating control unit will
cause burner to run with min. capacity.
Ø
If the boiler water temperature or steam pressure increases despite the operation of burner with
min. capacity, the modulating control unit will stop the burner.
