Pipe For Gas Connection; Electric Connection; Checking Heat Output - Officine Gullo DWFS4 Instructions For Installation And Use Manual

The gas connection must be done with steel or copper pipes, or otherwise with flexible steel
pipes in compliance with the national norms, if any exist. Each appliance must be provided
with a cut-off cock for rapid interruption of the gas supply. Once the appliance has been
installed, it is necessary to check for gas leaks for the pipe fittings; do not use a flame for
this purpose but a non-corrosive substance such as soapy water or foamy substances as
contained in leakfinder sprays. All our appliances undergo careful testing: the type of gas,
the operating pressure and the category are indicated on the data plate.
NB: The year of the appliance manufacture is shown in item "N" on the data plate. The first
two numbers (e.g. 93..) represent the year of manufacture.
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 con-
verting 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. (figure 1 item C).
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.
