When all the controls, as shown in previous paragraphs, have been accomplished, it will be possible to
proceed with the burner start up.
- Switch-on the burner. When reaching the preset temperature on the working thermostat, and with boiler's
thermostat closed, the control box starts the fan, the fuel pump and the ignition transformer. At the same
time, the balancing resistors are activated, to keep fuel temperature into the heater at a constant value.
- It begins, in this way, the combustion chamber prepurging, as well as the fuel circulation in the whole
circuit, so as to obtain an uniformity of temperature which allows a correct flowing of the same. The fuel
pressure, during prepurging, shall be around 16÷18 bar. If not, adjust the pressure to the specified value
through the regulator "D", purposely installed on the heating circuit (see figure).
- At the end of the prepurging, the control box shut off the solenoid valve "O" while opening the 1st stage
valve (for example valve "A"), allowing the burner ignition in Low Flame.
- In order to have a correct combustion, adjust the combustion air flow (see figure).
- The fuel pressure during burner's working shall be set to 23 bars.
