4 INSTALLATION

4.1 INSTALLATION PLACE

• The appliance must be installed in adequately ventilated
premises.
Connect the appliance according to the regulations in force: Gas
Safety (Installation and Use) Regulations, 1984; Health and
Safety at Work Act, 1974; Codes of Practice BS6173, 1982; The
building Regulations, 1985; The Building standards Regulations,
1981.

4.2 POSITIONING

• Place the cooker in position seeing to the levelling and height by
means of adjustable feet.
• Remove the protective film from the external panels by peeling it
back slowly in order to avoid any glue being left behind. If this
occurs, clean off the excess glue with benzine or other suitable
solvent.
• It is important to protect any close objects from the heat of the
appliance. Either insert heat protective material or leave a space
of at least 200 mm from the rear and sides of the appliance.
WARNING
The temperature at the base of the appliance exceeds 65°C. If
the floor material is flammable or not resistant to these
temperatures, it is recommended that a suitable heat resistant
material is placed between the appliance and the floor, with a
thickness of no less than 10mm (eg.steel). (fig.1)

4.3 CONNECTION TO THE WATER SUPPLY AND DRAINAGE.

(Installation layout)
• Connect inlet water pipes "1" & "2" to the main water supply by
intercepting taps and suitable mechanical filtres. Use the fittings
supplied.
• Before making the final connection, water should be allowed to
flow through the appliance in order to flush any corrosion or
impurities that may have formed.
• The out-let tap under the recipient should be adequately
connected to the drainage system.
• All connections should be heat resistant (minimum 100°C).
• The water used to generate the steam and cook the food must
be fit for human consumption and meet the following
characteristics:
- Total hardness 0.5 - 5° French;
- Concentration of chloride ions (CL-) ~ 10 ppm (parts per million);
- pH higher than 7;
- Electrical conductivity 50 - 2000 µS/cm at 20°C.
ATTENTION
The use of water with characteristics other than those indicated
above causes the general forfeiture of the warranty.
Do not use polyphosphates to remove the scale from inside
the pipes, as they can affect the proper operation of the
equipment.

4.4 GAS CONNECTION

• Before attempting any connection, ensure that the information
on the data plate corresponds to the type of gas available to the
user. In case of any difference, carefully follow instructions in
paragraph 5.5 "Conversion to a different type of gas".
• A safety cut-off valve must be installed in an easily accessible
position in every appliance.
• The connection of the appliances must be done with 3 piece
pipe fittings in order to facilitate disassembly.
It must be done by means of galvanised metallic or copper pipes
positioned well in sight.
If flexible pipes are used they must be stainless steel.
• After having carried out the gas connection, check its seal using
a frothy spray..
• Always remember that the volume of air necessary for combustion
is equal to 2 m3/h per Kw and that the safety regulations should
be applied:

4.4.1 Gas exhaust for system type "B11".

• For apparatus in category "B11", the exhaust gases must be
extracted by one of the following methods according the
regulations in force. connection flue should therefore be
connected and will be supplied on request: (fig.2)
• Remove the grid placed on the smoke extractor.
• Position the connection flue "A" onto flue "B" and fix with screws
"C".
1. Natural extraction. (fig 3)
Connection to a surely efficient flue, switch "D", " (available on
request), which discharges directly to the outside.
2. Forced extraction.
The gas ignition circuit must be directly connected to the extractor
device so that if the extraction flow falls below the prescribed
limit the gas flow is cut off.
Reignition after this can only be done manually.
3. Installation under an extraction hood.(fig. 4)
For installation under an extraction hood there should be a
distance of 1,8m between the top of the flue and the surface of
the appliance.
Ensure the filter is made of heat resistant materials, as the gas
expelled from the appliance can reach a temperature of 300 °C.
4.4.2 Gas exhaust for system type "A" (GB+IE).
Appliance type "A" should discharge in appropriate flues or similar,
which should be connected to an efficient duct or externally.
Alternatively an extractor fan can be used, with a capacity not inferior
to the installation regulations in force.

4.5 EQUIPOTENTIAL CONNECTION

• The appliance must be included in a equipotential system. This
connection should be undertaken with the set screw marked with
the symbol .
• The earthing and equipotential systems must comply with the
standards and regulations in force.
The manufacturer declines any responsibility if the safety
regulations are not complied with.
5 START UP PROCEDURE
Ensure that the apppliance is compatible with the type of gas
supplied by referring to the data plate. If not compatible refer to
paragraph 5.5.
To ignite burner, see ch.II "INSTRUCTIONS FOR USE".
WARNING:
Before igniting burner ensure that the jacket is filled with water
(see ch. II, par. 2.1).
5.1 IN-LET PRESSURE CONTROL (fig. 5)
• The pressure can be measured by using a "U" manometer or an
electronic manometer with a minimum calibration of 0.1 mbar.
• Unscrew nut "A" from input tube "B".
• Connect the manometer.
• Light the burner and check that the pressure reached is within
the prescribed limits.
• Finally, reassemble all parts and check. In the event of the
pressure not reaching the prescribed readings (see tab. 3), the
appliance should not be used and the gas supplier should be
contacted.
