1.4. LAWS, TECHNICAL PRESCRIPTIONS AND DIRECTIVES

When installing the appliance it is necessary to follow and comply with the following regulations:

 current regulations on the matter;

 any hygienic-sanitary regulations concerning cooking environments;

 municipal and/or territorial building regulations and fire prevention prescriptions;

 current accident prevention guidelines;

 standards for the use of combustible gas;

 standards for gas-fired systems utilizing on-tap or liquid petroleum gas;

 standards relating to gas-fired cooking appliances and similar equipment used large-scale catering.

Safety requirements;

 standards relating to gas systems for appliances used in professional kitchens and communal facilities;

 the regulations of the gas supply company or agency;

 electricity board regulations concerning safety;

 the regulations of the electrical power supply company or agency;

 any other local prescriptions.

1.5. SPECIAL REQUIREMENTS FOR THE INSTALLATION SITE

 The appliance belongs to the installation class A1 (no direct connection of a chimney of flue exhaust

system is required), so it is very important for the environment in which it is installed to be well-aired and
provided with all the safety openings prescribed for its power.

 In addition, it is good policy to locate the appliance under an extractor hood so that cooking vapours can

be removed rapidly and continuously.

 The gas supply system must be equipped with a rapid on off tap approved for the purpose.

 This appliance requires two water connections: one for hot and one for cold water. Each line must be

fitted with an on-off valve.

Warning! : The shutoff valves must both be located near to the appliance, within easy reach for

the user.

2.1. POSTIONING

 Remove all the packaging and check that the appliance is in perfect conditions. In case of visible

damage, do not connect the appliance and notify the sales point immediately.

 Remove the PVC protection from the panels.

 Dispose of packaging according to regulations. Generally material is divided according to composition

and should be delivered to the waste disposal service.

 Maintain a distance of 5 cm between the back (chimney) of the appliance and the wall. There are no

particular prescriptions regarding side distances from other appliances or walls, however it is advisable to
leave enough space in case of maintenance and/or repairs. It is advisable to fit a suitable heat insulation
if the appliance is in direct contact with inflammable walls.

 The appliance must stand level. Small differences in level can be eliminated by screwing or unscrewing

the adjustable feet: A significantly uneven or sloping stance can affect the operation of the appliance
adversely.
