Warning! : Only qualified technicians must perform the installation, maintenance and test of the
appliance.
Warning! : Before connecting any parts of the appliance to supplies, make sure that the latter is
equivalent the requirements stated in the technical data plate, if the appliance has
been designed for these supplies.

Water inlet pressure must be between 50 and 300 kPa, otherwise install a pressure regulator on the line
before the appliance.

Install a cut-off valve for each supply on the line before the appliance.

Water connections to 10 mm are fitted in the lower part on the left-hand side of the appliance.

Make connections according to regulations currently in force.

The choice of the gas piping depends on the diameter required for the type of gas, appliance and
installation and should be performed in conformity with current regulations.

The gas feed plant can either be fixed or be disconnected; if flexible pipes are employed they must be
made from stainless material and not be affected by corrosion.

If sealing materials are used for connections, they must be certified and approved for the purpose.

The gas fitting is located on the lower right side of the appliance

Once the appliance has been connected, carry out a leakage test on all the fittings connecting the
appliance to the plant. It is advisable to use a leakage spray, otherwise treat the parts with a foam that
does not produce corrosion; no bubbles should develop. Carry out the leakage test also on the rapid cut-
off valve.
Warning! : Flames are strictly prohibited for leakage tests!

Check that the appliance has been prepared (category and type of gas) equivalent to the family of gas
available on site. If not, it is necessary to convert the appliance to whatever is available. See the
paragraph "Conversion to other types of gas".

The appliance must be used with the correct injectors for its thermal power rating (See table 5 in the
"Technical data").

The operation of the appliance with its heating capacity depends on the inlet pressure and the calorific
power of the gas.

The pressure range (inlet pressure) within which the appliance is allowed to operated is stated in table 6b "Inlet
pressure" of the paragraph "Technical Data". The appliance shall not be operated out of the given
pressure range. If pressure should differ from the figures stated in table 6b, advise the gas board or the
company which has installed the system.

The lower calorific value of the gas can be checked with the supply company or agency, and should
comply with the information given in table 5 "Gas data" in the "Technical data" heading.
