Starting Up And Regulation With Methane Gas - baltur GI 350 ME Instrucciones

IGNITION AND GAS REGULATION (NATURAL GAS)
1) If not already done when connecting the burner to the gas pipes, taking the necessary measures and opening
doors and windows, it is necessary to bleed the air contained in the pipes. Open the union on the pipes close
to the burner, and slightly open the gas stop cock(s). Wait until you smell the typical gas smell, and then close
the cock. Wait for the necessary time, according to the specific conditions, until the gas present in the room is
dispersed outside and then restore the connection of the burner to the gas piping.
2) Check that there is water in the boiler and that the plant dampers are open.
3) Make sure that the combustion product discharge can occur freely (boiler and chimney dampers open).
4) Check that the electrical line voltage corresponds to that required for the burner, and that the electrical con-
nections (motor and main line) are preset for the available voltage value. Check that all electrical connec-
tions implemented on the spot are properly executed as per our wiring diagram.
5) Apply a pressure gauge with suitable scale to the gas pressure take-off to measure the regulation value (if the
expected pressure rate allows it, it is preferable to use a water column instrument, do not use hand instru-
ments for low pressures).
6) Regulate the air and natural gas for the ignition flame, for minimum flame and high flame, seguendi le istruzioni
nella guida rapida "LMV 51".
7) Verificare, che il motore giri nel senso corretto, se necessario, scambiare di posto due cavi della linea che
alimenta il motore trifase per invertire il senso di rotazione.
8) During the pre-ventilation step, make sure that the air pressure control switch changes position. If the air
pressure switch does not detect the sufficient pressure (it does not switch position), and thus the control box
"locks". Note that some "locks" at the first stage are normal since in the valve ramp pipes there is still air that
must be discharged before having a stable flame. To "unlock", press the "unlock" push button. At the first
stage there may occur further "locks" due to:
a) The gas pipes have not been sufficiently air-bled, and thus the gas quantity is not sufficient to allow a stable
flame.
N.B. Per effettuare una corretta regolazione si rimanda alla guida rapida sistema "LMV 51...".
9) Si raccomanda di controllare la combustione con gli appositi strumenti, se necessario, modificare la regolazione
esistente (aria ed eventualmente gas). É' indispensabile verificare che la percentuale di ossido di carbonio
(CO) presente nei fumi non superi il valore massimo ammesso di 0,1% e che la CO
per il metano.
10) Si raccomanda di eseguire una variazione costante di portata gas tra i punti impostati della curva.
11) Now, check the correct automatic modulation operation.
12) When the photoelectric cell is extracted from its housing, it cannot "see" the ultraviolet radiation emitted by the
flame and thus, The burner immediately shuts down in "lock". If the bulb is dirty with light oil, heavy oil, etc.,
clean it accurately. Note that a simple finger contact can cause a light greasiness, sufficient to impair the
photoelectric cell operation. To ensure a correct operation, the photoelectric cell current value must be sufficiently
stable, and must not decrease below the minimum value required for the specific control box. said value is
indicated as a percentage in the LMV 51 display.
13) Check the efficiency of the boiler thermostats or pressure switches (their start must shut down the burner).
