Lotus FTL-94G Instructions Pour L'installation Et L'emploi page 25

The appliance can be installed by itself or in a series side by side with appliances produced by us. There must be a
minimum distance of at least 10 cm between the appliance and the sides of the nearby cabinets made of inflammable
material. Take suitable measures to guarantee thermal insulation of the inflammable sides, such as, for example, the
installation of protection against radiation. The appliances must be installed in a suitable manner, observing the safety
standards. The small feet are adjustable to level the appliance.
The gas connection must be effected 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 cutoff 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 phoamy 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 by inserting a gauge for liquids (e.g. a U gauge). With a minimum definition of 0,1 mbar,
into the relative pressure outlet (see fig. B position C).
Remove the screw from the airtight pressure outlet, connect the rubber pipe of the U gauge and read the pressure.
After reading, remove the flexible pipe of the gauge, put back the screw, tighten hermetically and check the pressure
tightness.
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 correponds to the one supplied
by the manufacturer.
The connection pressure for methane gas is 20 mbar.
Check the plate, read the pressure and verify that the description of the nozzle installed correponds to the one supplied
by the manufacturer.
All burners are provided with special injectors which do not require regualtion of the primary air.

DISPOSALS FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS
Our appliances are tested and regulated with liquid gas /see plate).
The conversion or adaptation to another type of gas must be carried out by a specialized technician. The nozzles for the
various types of gas are supplied in a packet and are marked in hundredths of mm (see table of "burners" technical
data).
