GAS SYSTEM CONNECTION

- The unit should be supplied with gas having the characteristics and the pressure shown on Table II.
- The gas pressure is measured at the initial pressure outlet with the burner on (see Fig. 1) and art. 2.9.1.
- The equipment is tested and preset in order to work with the gas indicated on the external adhestive plate.
*N.B. Should the supply pressure vary more than +10% of the nominal pressure, it is advisable to install a pressure
regulator ahead of the unit to guarantee the nominal pressure.
- Gas supply connection should be performed by means of metal piping of an appropriate cross section and an approved
shutoff cock should be fitted at source.
- Having connected the gas supply, you should make sure no leaks exist at the joints by checking with bubble soap.

DISCHARGE OF EXHAUST FLUE PRODUCTS

The units should be installed in premises suitable for the discharge of flue products, which must occur in compliance with
the installation instructions. Our equipment (see Table 1.1 for technical data) is classified as:
2.8.1

GAS UNITS TYPE A

They are not suitable to be connected to a flue discharge control.
The gas unit should be positioned beneath a draft hood with its system complying with the Regulations. (This unit needs at
least 2cu.m/hr • kW T.C. (Thermal Capacity).
Check kitchen ventilation: it should by complying with the Regulations in force.
2.8.1

INCOMING PRESSURE CHECK (PE)

Pressure is measured with a manometer 0÷80mbar (precision at least 0.1mbar).
The pressure socket Fig. 1 is located on the G 1/2" gas ramp behind the panel; undo the screw (A) of the pressure socket (B),
attach the silicone rubber to the manometer, ignite the burner and take the incoming "dynamic" pressure.
Fasten the screw (A) back with a gas washer (C), check gas sealing with bubble soap.
