ELECTRIC CONNECTION
The appliance is supplied without the connection cable; to install it, proceed in the following way:
- Remove the back panel
- Push the connection cable through the cable channel, connect the conductor wires to the corresponding terminals
in the junction box and fix them into place.
- Block the cable with the cable blocker, and reassemble the panel. The earth wire must be longer than the others so
that if the cable blocker should break, it will disconnect after the tension wires.
N.B. The connection cable must have the following characteristics: it must be type H05RN-F and must have an
adequate section for the power of the appliance (see technical data table).
EQUIPOTENTIAL
The appliance must be connected to an equipotential system.
The connection screw is positioned at the back of the appliance and is identified by the symbol .
Attention!
The manufacturer will neither be held responsible for, nor will give any compensation during the guarantee
period for any damage caused, and which is due to inadequate installations not compliant with the instructions.
CHECKING HEAT OUTPUT
The appliances must be checked in such a way as to verify that the heat output is correct:
•
The heat output (thermal power) is indicated on the data plate of the appliance;
• Firstly, check that the appliance can be used with the type of gas supplied; then check that the indication
on the plate corresponds to the gas to be used. For converting to another type of gas, check that the type
of gas complies with what is stated in this instruction manual.
The pressure is read with a gauge (minimum resolution of 0.1 mbar) inserted in the relative pressure outlet.
Remove the hermetically closed screw and insert the gauge pipe.
After reading, put back the screw tightening it hermetically and check for pressure leaks.
Connection for liquid gas G30/G31
The connection pressure for liquid gas is 30 mbar with butane and 37 mbar with propane.
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one
supplied by the manufacturer.
Connection with natural gas H G20
The connection pressure for natural gas is 20 mbar.
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one
supplied by the manufacturer.

CHECKING PRIMARY AIR TO THE MAIN BURNERS AND PILOT NOZZLES
All the burners are fitted with an air regulator by means of which the primary air can be varied thanks to an adjustable
bush that can be locked with a screw. In the Burner Technical Data table you will find the approximate values for the
“h” parameter (primary air). The flow of primary air must be regulated so there is no detachment of the flame when the
burner is cold or a return of the flame when the burner is hot.
The pilot air is regulated when the appliance is tested and inspected for the gas it is set for.
If you are going to change to a different type of gas, regulate the air by means of the adjusting bush until the flame
stops sputtering and becomes an intense blue colour.
