S.p.A. declines all responsibility for damage to persons and/or property caused by unauthorized persons
having tampered with the appliance. Proceed with the following conversions if the appliance must be used
with a different type of gas.
To switch from Natural gas to L.P.G. and vice versa, it will be necessary to change the main injectors and
to fit the delayer union to the gas valve (part F. fig. 23). Now adjust the minimum and maximum gas
pressure values on the gas valve (see relative paragraph).

Being the flame modulating type, this appliance has two fixed pressure values: the minimum and
maximum rate. These must be those indicated in the chart for each type of gas.
Attention Attention Attention Attention Attention - The minimum pressure must be regulated first. This will ensure correct burner
ignition. Following this, regulate the maximum pressure value. Each minimum pressure
adjustment involves a variation to the maximum setting value. Since they are particularly
delicate, the following regulating operations must only be carried out by Specialized
Personnel.

Connect a suitable pressure gauge to the pressure test point above the gas valve.
Keep button depressed for more than 5 seconds. The following message will appear on the display:
Use buttons on the right to adjust the current to 0 mA.
Press button . The boiler will operate in TEST mode.
Remove protective cap "b" from the top of the coil.
Adjust the minimum pressure value using nut "c". Turn this screw anticlockwise to decrease the pressure
or in a clockwise direction to increase it.
Switch the burner off and on three or four times, depressing keys
pressure remains regulated and that the burner regularly ignites. Further adjustment is required if this fails
to occur.
Having terminated this operation, check the maximum pressure value.
