by testing with soapy water.Hold the regulator and tighten the screw connec-
tion; the regulator must never be turned.
After correctly installing the regulator on the cylinder valve, the gas flow is
opened by turning the valve handwheel.
To close the gas flow, follow the procedure in reverse (fig.11).
Replacing the cylinder
Make sure that all the appliance’s valves are closed and the cylinder valve is
closed.
Then disassemble the regulator RR by unscrewing the screw connection.
-If the components were already assembled
Connect the pressure regulator (RR) to the gas cylinder as explained previously
in point 11
LEAK TEST:
The test must be carried out by competent personnel in a well-ventilated area,
without naked flames or other sources of heat.With the regulator connected
to the cylinder, activate the cylinder valve by turning it 1 and a 1/2 rotations
anticlockwise.
Brush all the hose connections, the fittings to the gas valve, the connection
of the regulator to the cylinder and the valve of the gas cylinder with a 50/50
solution of water and detergent.Bubble formation indicates a leak.If a leak is
found, close the cylinder valve (clockwise), disconnect the regulator from the
gas cylinder and remove the gas cylinder moving it to a cool, open and well-
ventilated place.For assistance, contact your dealer or gas supplier.
CAUTION:
DO NOT CHECK FOR GAS LEAKS WHEN THE APPLIANCE IS HOT, WAIT UNTIL IT
IS COOL.
DO NOT USE THE HEATER IF THERE IS A LEAK.
DO NOT USE NAKED FLAMES TO PERFORM THE LEAK TEST.
DO NOT USE ANY ELECTRICAL EQUIPMENT IN THE PRESENCE OF A GAS LEAK.
