8) Affix the label (Appliance regulated for ) indicating the new type of gas to the plate provided on the
appliance.
Seal the gas valve adjustment component after regulation.
(*) For LPG (Butane G30/Propane G31) gas, a stage I pressure reducer must be installed in the
vicinity of the tank to reduce the pressure to 1.5 bar; another stage II pressure reducer must be
installed on the main outside line beside the building to reduce the pressure to the values indicated
on page 39.
10.1.2Conversion from LPG to Natural Gas
1) Close the gas supply tap and disconnect the power supply.
2) Disconnect the combustion torch from the solenoid valve EV1 (30 mm spanner).
3) Unscrew the nozzle (it has a crosswise slot on the head) from inside the torch (see fig. 12 page 18)
taking care not to damage the electrodes (ignition and flame detection) located on the head of the
torch and relevant wires.
4) Replace with the nozzle in the conversion kit after checking that the diameter corresponds to the
one given on the ratings plate.
5) Connect and clamp the torch to the solenoid valve.
6) Adjust the burner pressure with the pressure regulator of the solenoid valve, turning the screw (3)
in fig. 30 on page 38.
7) Start up the appliance and check that the supply pressure to the burner measured at point (2) figs.
29-30 page 38 corresponds to the ratings plate value.
8) Check the gas seal on the threaded joints.
9) Affix the label (Appliance regulated for ) indicating the new type of gas to the plate provided on
the appliance.
Seal the gas valve adjustment component after regulation.
On models EOLO 70/EOLO 90
Models Eolo 70 and Eolo 90 are provided with a second solenoid valve (see fig. 30 page 38).
Change the nozzle on the second solenoid valve as follows:
1) Disconnect the tube (5) from the solenoid valve EV2 (30 mm spanner), (fig. 30 page 38).
2) Unscrew the nozzle (it has a crosswise slot on the head) from inside the extension connected to the
tube (5).
3) Replace with the nozzle in the conversion kit after checking that the diameter corresponds to the
one given on the ratings plate.
4) Connect and clamp the tube (5) to the solenoid valve EV2.
5) Adjust the burner pressure with the pressure regulator of the solenoid valve, turning the screw (3)
in fig. 30 on page 38.
6) Start up the appliance and check that the supply pressure to the burner measured at point (2) figs.
29-30 page 38, corresponds to the ratings plate value.
7) Check the gas seal on the threaded joints.
8) Affix the label (Appliance regulated for ) indicating the new type of gas to the plate provided on
the appliance.
Seal the gas valve adjustment component after regulation.
