Starting Up And Regulation With Light Oil - baltur GI 1000 Serie Mode D'emploi

STARTING UP AND REGULATION WITH LIGHT OIL

1) Check that the characteristics of the nozzle (delivery and spray angle) are suitable for the furnace
(see BT 9353/1). If not, replace it.
2) Check that there is fuel in the cistern and that it is, at least visually, suitable for the burner.
3) Check that there is water in the boiler and that the system's gate valves are open.
4) Check, with absolute certainty, that the discharge of combustion products can take place freely (boiler and
chimney lock-gates should be open).
5) Make sure that the voltage of the electric line to which the burner is to be connected, corresponds to that
required by the manufacturer, and that the motor's electrical connections have been correctly prepared to
match the voltage rating available. Also check that all the electrical connections carried out on the spot are in
accordance with our electric wiring diagram.
6) Make sure that the combustion head is long enough to enter the furnace to the extent specified by the boiler
manufacturer.
7) Remove the protective cover from the rotating disk inserted on the servomotor which regulates delivery
(fuel/air). On this disk have been fitted adjustable screws which are used to control the fuel and the relative
combustion air.
8) Check that the air regulation device on the combustion head is in the position considered necessary for the fuel
delivery required (the air passage between the disk and the head should be considerably closed when the fuel
delivery is considerably reduced; on the other hand, when the nozzle has a fairly high delivery, the air passage
between the disk and the head should be relatively open (see Chapter "Regulation of the Combustion Head").
9) Put the two modulating switches in the "MIN" (minimum) and "MAN" (manual) positions.
10) Start up the fuel supply auxiliary circuit, check its efficiency and regulate the pressure at about 1 bar
(if the circuits is supplied with a pressure regulator).
11) Remove from the pump the vacuumeter connection point plug and then open slightly the gate valve fitted on
the fuel arrival pipe. Wait until fuel comes out of the hole, without air bubbles, and then re-close the gate valve.
12) Insert a manometer (end of the scale about 3 bar) into the vacuumeter connection point on the pump and
control the value of the pressure at which the fuel arrives at the burner pump. Insert a manometer (end of the
scale about 30 bar) into the manometer connection point provided on the pump and control its working pressure.
Insert a manometer (end of the scale about 30 bar) into the special connection point of the first flame return
pressure regulator (see 0002900311) in order to control the return pressure.
13) Now open all the gate valves and any other interception devices fitted on the light oil pipelines.
14) Put the switch on the control panel in the "O" (open) position and give current to the electric line which the
burner is connected to. Check, by pressing manually the relative relay, that the fan and pump motors rotate in
the right direction. If they do not, exchange the places of the two cables of the principle line in order to inverse
the sense of rotation.
15) Start operating the burner pump by pressing manually on the relative relay until the manometer, which measure
the working pressure of the pump, indicate a slight pressure. The presence of low pressure in the circuit
confirms that filling up has taken place.
16) Insert the switch on the control panel to give current to the control box. If the thermostat (safety and boiler) are
closed, the control box's programmer will be connected and will insert the burner's component devices according
to its pre-established programme. The units starts up in this way, as described in Chapter "Description of
Operations").
NOTE: To adjust the gas pilot flame proceed as follows:
- disconnect the wire from terminal n° 18 of the LFL... control box to prevent the electromagnet being
switched on.
- disconnect the wire from terminal n° 17 of the LFL... control box (intermittent pilot) and connect it to
terminal n° 18 (pilot always on).
- ignite the burner, adjust the quantity of gas and air for the pilot flame and check for proper ignition
several times.
- when adjustment is over restore the original connections.
