Incoming Pressure Check (Pe); Nozzle Pressure Check (Pi); Adjusting The Minimum Thermal Capacity; Liquid Gas Operation Control - Eurofrequence Minima Serie Instructions Pour L'installation, L'emploi Et L'entretien

2.4.1 INCOMING PRESSURE CHECK (PE) FIG. 2
Pressure is measured with a manometer 0 ÷ 80mbar (precision at least 0.1mbar).
The pressure socket Fig. 2 is located on the G 1/2" gas ramp behind the panel; undo the screw (A) of the pressure socket (B),
attach the silicone rubber to the manometer, ignite the burner (Fig. 1 position T) and take the incoming "dynamic" pressure.
Fasten the screw (A) back with a gas washer (C), check gas sealing with bubble soap.
2.4.2 NOZZLE PRESSURE CHECK (PI) FIG. 1
The pressure socket is located above the nozzle holder (Fig. 1).
The silicone rubber is prepared for high temperatures and should be protected with tin foil to avoid its burning.
2.4.3

ADJUSTING THE MINIMUM THERMAL CAPACITY

The right minimum for thermal capacity is achieved by means of the "calibrated" bypass idle screw firmly tightened in
accordance with Table II.
Ignite the burner according to Chapter 6 "Instructions to Users" in the maximum position (8); after approx. 15 minutes of pre-
heating, turn knob to the minimum position (1).
For the 2nd and 3rd Family, the bypass idle screw should be all screwed down.
2.4.4

LIQUID GAS OPERATION CONTROL

Check whether the fitted nozzles comply with the indications on Table II,.
Check whether the incoming pressure complies with the indications on Table II.
Make sure that the L.P.G. gas system has two pressure regulators of suitable capacity and that the evaporation capacity is
sufficient.
See also the publication "Installation Regulations and Characteristics of L.P.G. Systems".
2.5

OPERATION CONTROL

- Start the unit in accordance with the use instructions.
- Make sure there are no leaks following the local procedures.
- Check the ignition and interignition of the pilot burner and the main burner.
- Make sure the flue gases are discharged regularly.
- Write on a sticker, to be glued to the unit label, for what gas and pressure the unit has been calibrated

REPLACING THE PILOT BURNER NOZZLE

N.B. In order not to break the spark plug, it is advisable to first remove it (6 and 7 Fig. 1).
To change the pilot injector, you should unscrew the nut (4 Fig. 1) with a size-10 spanner and replace the injector (5 Fig. 1)
with one corresponding to the gas type chosen and shown on Table II.
3.2

REPLACING THE BURNER NOZZLE

Replace the burner nozzle (U Fig. 1) with one corresponding to the gas type chosen and indicated on Table II.
Ignite the pilot burner (8 Fig. 1) by turning the knob (Fig. 3) to position (
knob to position 8.
3.3

REPLACING THE IDLE BYPASS SCREW

Replace the idle screw (11 Fig. 2) located on the thermostat, with one corresponding to the gas type chosen, and complying
with injector Table II.
Screw the idle screw or bypass all the way down.
After replacing the nozzles, apply on the existing label the one supplied with the machine indicating the new type of gas.
