VERIFY:
- That piping system is perfectly sealed;
- That the use of hoses is avoided whenever is possible (use copper pipes preferably);
- That depression is not greater than 0,45 bar, to avoid pump's cavitation;
- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 12 bar during the testing of burners. Before starting the burner, bleed the air in
the pump through the gauge port. Fill the piping with light-oil to facilitate the pump priming.
Start the burner and check the pump feeding pressure. In case the pump priming does not take place during the first
prepurging, with a consequent, subsequent lock-out of the burner, rearm the burner's lock-out to restart, by pushing
the button on the control box. If, after a successful pump priming, the burner locks-out after the prepurging, due to a
fuel pressure drop in the pump, rearm the burner's lock-out to restart the burner. Do never allow the pump working
without oil for more than three minutes. Note: before starting the burner, check that the return pipe is open. An even-
tual obstruction could damage the pump sealing device.
Once having installed the burner, check the following items:
- The burner power feeding and the main line protection fuses
- The correct length of pipes and that the same are sealed.
- The type of fuel, which must be suitable for burner.
- The connection of boiler's thermostats and all the safeties.
- The motor rotation direction.
- The correct calibration of the motor's thermal protection.
When all the above mentioned conditions are checked and accomplished, it is possible to go on with burner's tests.
Power the burner. The control box feeds the ignition transformer and the burner's motor at the same time, which will
run a prepurging of the combustion chamber for about 20 sec.
At the end of prepurging, the control box opens solenoid valves and the burner starts. After a safety interval of 5
seconds and a correct ignition, the control box turns off the ignition transformer and, 10 seconds later, sets the motori-
sed air damper to its maximum opening (High flame). In case of faulty ignition, the control box switches the burner
into safety condition within 5 second. In such a case, the manual rearming of the burner shall not take place before 30
seconds have elapsed from the burner's safety shutdown. In order to obtain an optimal combustion, it is necessary adju-
st the LOW - HIGH flame air flow, according to the instruction given further on. During such a phase, it will be possi-
ble to manually switch between HIGH and LOW flame and viceversa, through the High/Low flame switch. At the end
of the adjusting phase, leave the switch in position AUTO.
In case of burner lockout, it is possible to read which cause originated it. Proceed as follows: with the burner in lockout
mode (red LED switched on) keep pressed the lockout button for more than 3 sec. then release it. The red LED will
blink according to the following error code list:
