02.0 LOCAL WHERE IS INSTALLED THE OVEN

The local must have the following characteristics:

CHIMNEY: for exhaust vapour, with an efﬁcient damper suitable for receiving a pipe

of a diameter of not less than 110 millimetres. Use the evacuation chimney with the

compensation opening.

POWER SUPPLY: at least equal to the maximum oven power. Lower power may be

installed as the oven is equipped with electronic control with power partializers (For more

information contact the oven manufacturer). In any case, consider other electrical utilities to

determine the power to be installed in the room where the oven will be installed.

03.0 INSTALLING THE OVEN

03.1 Preliminary operations

To install a oven the following operations must be performed:

UNLOAD the oven through a forklift or crane. Lift the oven only using the side hooks.

CONTROL the state of the oven and all its constituent parts

WARNING

Do not lift the oven by the landing or other parts not predisposed for handling.

In the event of anomalies or breaks, inform the manufacturer of the product,

otherwise the warranty will be void.

The Zeno oven is delivered with its base. If need be, you may separate the oven from the

base and install it on an existing surface, simply unscrew the 4 bolts present at four corners

on the bottom of the oven.

PUTTING THE OVEN ON A LEVEL SURFACE.

Place the oven on a surface that will be able to support its weight. It’s important that the

surface be level so as not to undermine the stability of the appliance.

PUTTING THE OVEN WITH THE BASE

The product comes with a four-wheel base; just ﬁnd the perfect place for your oven and

install it.

BUILT THE OVEN

The Zeno oven can be installed directly into the kitchen wall but a minimum safety distance

of at least 20 cm must be kept from combustible materials. Enough room to manoeuvre

must be allowed to access the right-hand side of the oven which houses the wirings and

the heating elements. N.B. Allow for at least 1 m clearance to remove heating elements.

EN

03.2 Electrical connection

The product is supplied with cable of 1,5 m and without an electric plug. The electrical

plug assembly and oven connection operations must be carried out by qualiﬁed

personnel.

Electrical oven connection operations must be carried out by qualiﬁed personnel, possession

of the necessary technical requirements established by the country where the oven is

installed.

The oven supply cable must be connected to an external polarized circuit-breaker with

minimum contact opening of 3 mm in the immediate vicinity, with the following minimum

characteristics:

MODEL Power Nominal Electromagnetic Curve Power Break

Amp kA

ZENO 19,5 Type C 10

Over-current protection devices must comply with the requirements of the relevant

standards CEI (or corresponding publications I.E.C) The devices used for the connection

must be CE marked if installed in European Community countries, or trademarks recognized

in the country of installation and if possible of quality marks. The degree of protection of

the casings must be no less than IP 44 with the characteristics set by the CEI EN 60529 “

Grades of protection of casings”. Verify that the oven has a ground clamp connected to a

grounding system conforming to the CEI standard 64-8 “Earthing Plants” (or corresponding

IEC publication).

03.3 Connection to the chimney and to vapor discharge

The connection operations of the oven vapor discharge chimney, must be performed by

qualiﬁed personnel.

The connection to the ﬁreplace must be done through, a steel or aluminium tube of

diameter not less than 100 millimeters. The damper of the chimney must ensure vapor

evacuation in the most unfavorable weather conditions.

Any fan in the room they must not compromise the damper of the chimneys. Pollutants

such as hydrocarbons will not have to affect the chimney.

03.4 Pre-testing of the oven

During the ﬁrst empty oven cycle the temperature should be gradually increased. Starting

from low values occasionally turn off the oven or graduate the calories so that variations of

40/50 degrees they do not occur in less than an hour.

This is to avoid unpleasant odours issued from the ﬁrst heating of insulating materials and

allow for a gradual drying of the oven.

WARNING

Be careful that the implant of land is the ﬁrst thing to be connected

to avoid risks relative to dispersion currents.
