Pipe For Gas Connection; Checking Heat Output; Connection With Natural Gas H G20; Checking Primary Air In Main Burners - Lotus F13-74G Instructions Pour L'installation Et L'emploi

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 leak-
finder sprays. All our appliances undergo careful testing: the type of gas, the operating pressure and the category are
indicated on the data plate.
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 must be read with a gauge (minimum resolution of 0.1 mbar) into the relative pressure outlet (see fig. 1
position 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.
All the burners are provided with a stirrup for regulating primary air, which must be placed at a distance H indicated in
the technical data table.
