INSTALLATION

2.2.1

LAWS, REGULATIONS AND TECHNICAL DIRECTIVES TO BE COMPLIED WITH

The following indications should be observed during installation:
- Accident and fire regulations in force
- Prescriptions by the gas supply Company, which should issue an authorisation before installation.
- Instructions for the "Installation of gas equipment"
- Hygienic regulations.
2.2.2

INSTALLATION PLACE

- The unit should be installed in adequately ventilated places. (This unit requires a draft of at least 2cu.m/hr l kW T.C.
(Thermal Capacity).
- Install the equipment in compliance with the safety rules applicable in the country where the equipment is installed.
2.2.3

POSITIONING

- The various units may be installed individually or together with other units of our range.
- This unit is not suitable for encasing.
- The distance between side walls must be a minimum of
10cm; should the distance be less or the wall or floor
material be flammable, it is essential to use a thermal
insulator.
2.2.4 ASSEMBLY OF TOP EQUIPMENT ON
COUNTERBASIS
Unscrew and take away the two frontal foot (P) from the
equipment, which is to be located on the counter, place it
on this so that the 2 back foot (N) fit in the corner of the
base as represented in the picture.
Place the equipment completely and fix it screwing the 2
frontal foot (P) through out the base's holes for the fixing
of it.
2.3

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).
- The unit is tested and fitted to operate with natural gas H G20 - 20mbar.
* 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.
2.3.1

DISCHARGE OF EXHAUST FLUE PRODUCTS VIA A DRAFT HOOD. TYPE "A1" UNIT.

The gas unit should be placed beneath a draft hood with its system complying with the Regulations. (This unit needs at least
2cu.m/hr l kW T.C. (Thermal Capacity).
Check kitchen ventilation: it should by complying with the Regulations in force.
2.3.2

WATER DRAINAGE

N.B. Maximum temperature 100°C.

HOW TO ACHIEVE THE NOMINAL THERMAL CAPACITY

Check whether the unit is fitted for the gas type, pressure and category corresponding with the main gas supply.
Indication shown on packing and/or the label of the unit.
If the unit is fitted for another gas type or pressure, you need to first effect a change over to the other gas type.
See Table II for the nozzle, the idle screw (bypass), the primary air regulation, (X mm), the pilot nozzle and the nozzle pressure
for the main burner.
N.B. The names of nozzles "2H" and "3+" are shown on the left side of Table II.
2H= G20 - 20mbar
3+= G30 29mbar and/or G31 - 37mbar coupled gas and pressure. In our sector, we almost always have to deal with G31 - 37mbar!
Table II shows the types of gas and pressure for all burners and respective nozzles, the X mm distance for the adjustment of
