15
ELECTRICAL CONNECTIONS
To put the oven into operation, the required connections to the local area network must be ensured.
The user is in charge of ensuring the required correct electrical connection characteristics, by making sure to
provide a proper grounding.
The oven works at 400V+T+N /50Hz
Total power is 11 Kw
Install a 32 A (3 phases + neutral + ground) electrical socket near the oven.
In case the use of the provided industrial plug isn’t compatible into your country, you can replace it using a
different model (rated current 32 A) suitable to the available socket existing into the installation place.
If the power cord isn’t enough long it can be replaced using a cord of the same sections and the same type
(five-pole cable three phases + neutral + ground, size 5 x 4 mm²
Keep electrical cables away from the hot parts of the oven.
WARNING !
Before making any the electrical connection, it is important to check that the machine is OFF.
Getting the circuit breaker provided with the oven turned OFF.
WARNING !
Make sure the power supply line has been isolated.
WARNING !
The connections to the plant's electricity network must be made by the Customer's qualified
personnel (Electrical Maintenance Engineer).
The purchaser is responsible for the conformity of the connection between machine and earthing system.
Before setting up the electrical connection, make sure that:
• the maintenance engineer is aware of the regulations in force in the country of installation;
• the frequency and power supply voltage values of the machine correspond to the power supply network
values;
• the section of the electrical cables used is adequate to the absorption;
• the electrical power supply line is adequate to support the maximum machine absorptions;
• the grounding of the circuit conforms with standards EN 60204-1 or however in compliance with the
standards of the installation place;
• the materials used in the grounding system have adequate strength or adequate mechanical protection.

ELECTRICAL MAINTENANCE
WARNING !
Before starting any maintenance operation disconnects electricity through the circuit breaker
In case of components/accessories replacement use only original spare parts.
Should the customer not use genuine spare parts or parts authorised in writing by the
Manufacturer, the latter shall be relieved of any liability as regards machine operation and
operators' safety.
Authorization and/or instructions must always be given in writing. It is forbidden to operate
the machine without written permission and the Manufacturer disclaims any and all
responsibility.
WARNING !
Maintenance and repair of the machine are only allowed by qualified technicians with
knowledge of equipments, necessary operations, related risks and correct procedure to work
safely.
ELECTRIC POWER CORD
In case of replacement, the correct type of cord to use is five-pole cable three phases + neutral + ground,
size 5 x 4 mm²
Leave the cord enough long to allow an easy maintenance.
A damaged cord should not be repaired but it must be replaced.
Power cord replacement must be made by specialized technicians.
BULB REPLACEMENT
Before to start any operation , disconnect elecricity and wait for the oven gets cool
Remove the glass protection of the bulb by unscrewing it, replace the bulb and reposition the glass
protection by screwing it into its place.

OVEN VENTING
The venting system of our wood burning ovens is to direct connection, exploiting the natural draught.
The oven employs an integral exhaust hood above the front opening. All flue gases exit the front opening and
drafts into the exhaust hood to be subsequently expelled through a flue pipe (150 mm / 6” O.D.) located at the
top of the oven.
As there isn’t any emission of exhaust gas but just smokes of cooking and heat the pipe need just to allow
venting of them so, if local regulations allow it, the oven could be placed under an exhaust hood avoiding
connection of the flue to a duct venting system (chimney),
WARNING !
Rules about ventilation change according the different jurisdiction of the country of
installation so submit your venting plans to local authorities about possible restrictions and
installation procedure accepted before proceeding with installations.
The purchaser is responsible of the conformity, correct installation and correct working of the
venting system.
