Moretti Forni P110G C/A, Instruction Manual, Page: 7 / 42

UK/6
For aeration of the area where the oven will be installed, and discharge of
exhaust fumes, see the instructions in 2.4.
The vapour and gas exhaust pipe is located on the back of the oven (fig. 9
item C).
WARNING! The steam and exhaust gas extractor pipe will heat up
when the oven is working. Do not touch it, or you will burn yourself.
The equipment can be installed in one of the following ways:
A) direct ventilation system installation
B) under exhaust hood installation
A) Installing with direct ventilation (see fig. 9a)
WARNING! The vapour and gas exhaust connection must be done
exclusively by qualified personnel in compliance with current
regulation.
Fit the closing plug at the end of the exhaust (fig.9 item B) turning the
three screws provided so that inclined part faces the front of the oven; then
fit the exhaust extractor switch itself (fig.9 item A).
Using a suitable pipe:
Ø7 7/8” (Ø 200)
per P110GA-A2-B-B2 - P150GA-A2
Ø9 27/32” (Ø 250)
per P110GA3-B3 - P150GA3
of the kind commercially available, make the connection to the extractor
switch (Fig. 9 item A) in compliance with current exhaust fume discharge
requirements.
WARNING! Once applied the exhaust extractor switch (fig.9 item A)
and the subsequent pipes fix them mechanically with the provided
self-tapping screw.
B) Installing under ventilation hood (see fig, 9b)
The appliance must always be installed under a suction hood, with a
heat-resistant filter, or under a suction ceiling that must guarantee
evacuation of combustion and cooking fumes at all times.
The suction system must be suitably sized and fitted with at least one
closing device connected to the gas line, which comes into operation to
intercept the gas in the event of a malfunction in the suction hood or
ceiling itself.
The hood must be sized so as to cover the appliance completely, and to
extend by at least 6” (15 cm) beyond it on all sides not adjacent to a wall;
the distance from the floor to the lower edge of the hood must not exceed
95” (240cm). All these distances are merely indicative, and current
installation regulations must always be taken as a reference. Take into
account that the proper air flow values will depend on the design
efficiency of the hood, the amount of air circulating inside the appliance
and the flow of air coming in and out of the room.
Fit the deflector (fig.9 item F) at the end of the exhaust (fig.9 item C) so
that open area faces the front of the oven; then fix the deflector turning the
three screws provided.
Connect outwards also the hole on the front part of the appliance through a
suitable connection Ø59 1/16” (Ø150 mm) (picture 9, item D). This
connection must be independent from the rear chimney.
2.5.3 ELECTRICAL CONNECTION
WARNING! Electrical connection must only be carried out by
specialised personnel, in compliance with current local state Electric
Quality Assurance Corporation requirements. In the absence of
local codes, Electrical connection must conform with the National
Electrical Code (NEC) ANSI/NFPA70 and Canadian Electrical
Code CSA C22.2.
- Before starting the connection procedure, check that the earthing
system is provided in accordance with local codes.
- Before starting the connection procedure, check that the main
power switch has been turned to the “off” position.
- The rating plate contains all the information necessary for proper
connection.
2.5.3
. 1 ELECTRICAL CONNECTION OF THE BAKING
CHAMBER
WARNING! Each baking chamber must be fitted with a main
omnipolar switch with fuses or an automatic switch suitable for the
values shown on the plate, to allow the single appliances to be
disconnected from the mains. The switch must have a contact aperture
of at least 3 mm .
NOTE!
The device selected should be in the immediate vicinity of the
oven and within easy access.
Electrical supply for the equipment is 208/240V 1Ph 60Hz (see rating
plate fig.2 item A).
To carry out electrical connection, remove the protective cover located on
the rear side of the baking chamber (fig. 10). The connection cable must be
supplied by the installer.
Insert a cable with a minimum cross-section of 14 AWG (3 x 2,5 mm
2
) in
the cable raceway provided (fig.11 item A) and connect it to the terminal
board as illustrated in fig.12.
When connection has been completed, check that the supply voltage, with
the appliance running, does not differ from the rated value by more than
±5%.
WARNING! The flexible wire for connection to the power supply
must have characteristics at least equal to the model with rubber
insulation H07RN-F and must have a rated section suited to the
maximum absorption.
WARNING! It is essential that the oven be properly earthed. A
special earth terminal has been provided for this purpose on the
connection terminal board (fig.12). It is marked with the earth symbol
and the earth wire must be connected to it.
These ovens must also be included in the unipotential system. The
terminal to be used for this purpose is located at the back of the oven
(fig.11 item B). It is marked with the symbol TERMINAL FOR THE
UNIPOTENTIAL SYSTEM.
2.5.3.2 ELECTRICAL CONNECTION OF THE PROOFER
WARNING! The compartment must be fitted with a main homopolar
switch suitable for the values shown on the plate, to allow the single
appliances to be disconnected from the mains.
NOTE! The device selected should be in the immediate vicinity of the
appliance and within easy access.
The proofer is delivered with a voltage of 208/240V 1Ph 60 Hz, as
indicated on the rating plate (fig. 2-part B).
To carry out electrical connection, remove the protective cover located on
the left hand rear side of the compartment
(fig.13).
The connection cable must be supplied by the installer.
Insert a cable with a minimum cross-section of 14AWG (3 x 2,5 mm
2
) in
the cable raceway provided (fig.14 item A) and connect it to the terminal
board as illustrated in fig.15. When connection has been completed, check
that the supply voltage, with the appliance running, does not differ from
the rated value by more than
±5%.
WARNING! The flexible wire for connection to the power supply
must have characteristics at least equal to the model with rubber
insulation H07RN-F and must have a rated section suited to the
maximum absorption.
WARNING! It is essential that the oven be properly earthed. A
special earth terminal has been provided for this purpose on the
connection terminal board (fig.15). It is marked with the earth symbol
and the earth wire must be connected to it.
These ovens must also be included in the unipotential system. The
terminal to be used for this purpose is located at the back of the oven
(fig. 14-part B). It is marked with the symbol TERMINAL FOR THE
UNIPOTENTIAL SYSTEM.
WARNING! The manufacturer declines any responsibility in the
event of failure to comply with the above safety precautions.

OPERATION
3.1
PRELIMINARY CONTROL OPERATIONS
WARNING! Before commencing start-up and programming of the
oven, always check that:
all electrical and earthing connections have been properly made;
all gas and vapour exhaust connections have been properly made;
all control operations must be carried out by specialised technicians
holding a proper license.
For more even results, we recommend avoiding the use of temperatures
above those recommended for the type of product being baked.
3.1.1
CHECKING NOZZLES
Check that the oven (rated gas category and type) is set up for the type and
family of gas supplied. If this is not the case, convert to the type of gas
available.
The oven must be put into operation using the nozzles foreseen for the
rated thermal capacity (see technical data TAB.1).
