BURNER START-UP AND ADJUSMENT
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.
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 the fuel pump and the 1st stage (Low flame) solenoid valves,
the ignition transformer produces a spark and the burner ignites. After a safety interval of 5÷10 seconds and a
correct ignition, the control box turns off the ignition transformer and, 10 seconds later, sets the air damper
to its maximum opening and opens the 2nd stage solenoid valve (High flame). In case of faulty ignition, the
control box switches the burner into safety condition. In order to obtain an optimal combustion, it is neces-
sary adjust the LOW - HIGH flame air flow, according to the instruction given further on. The fuel pump
feeding pressure, must remain around 12 bar.
SIEMENS LMO 44 CONTROL INFORMATION SYSTEM
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:
