START-UP
Function check
– Start-up the appliance according to instructions
for use and check the regularity of the burner
ignition, the absence of gas leaks and the efficiency
of the burnt gas exhaust system.
– If necessary consult paragraph “Analysis of
several failures”.
Nominal heat input check
– After installation or adjustment to another type
of gas and at each maintenance intervention
check the heat input of the appliance.
– The nominal heat input is stated in the “Technical
data” table.
– The appliance operates at the nominal heat
input when the nozzles assembled are suitable
for the type of gas used and the inlet pressure is
the one indicated in Table T1.
– For the measurement of the inlet pressure read
paragrah “Inlet pressure check”.
Inlet pressure check
– For the measurement of the inlet pressure use a
gauge having a minimum definition of 0.2 mbar.
– Remove front panel of appliance, remove seal
screw C from upstream pressure tapping and
connect the gauge pipe.
– Carry out the measurement with appliance on.
– If the value is not within the limits indicated in
Table T3, interrupt the operation of the appliance
and contact the gas delivery body.
– Disconnect the gauge pipe and screw down seal
screw C.
ANALYSIS OF SEVERAL FAILURES
Difficult or lacking pilot ignition
– Insufficient gas inlet pressure.
– Obstructed nozzle or main.
– Defective gas cock.
INSTALLATION INSTRUCTIONS
WARNINGS
Installation, adjustments and maintenance of the
appliances must be done by authorized installers,
in accordance with the safety standards in force.
The manufacturer declines any responsibility
if such obligation is not observed.
INSTALLATION
Positioning
– The overall/connection dimensions and the tech-
nical data are stated in the pages in the appendix.
– Install the appliances only in sufficiently aired
rooms.
– Fry-tops are type “A” appliances and for this
reason the rooms must be ventilated in
accordance with the technical standards in force.
– Position appliances at least 10 cm from the
nearby walls. Such distance can be less when
the walls are incombustible or protected by a
thermal insulator.
– The appliances are not suitable for built-in
installation.
Assembly
– Remove the film which protects the external
panels. Any glue remaining on these is to be
removed with a suitable solvent.
In line union of the 600 series appliances
– Put the appliances next to eachother and level
them at the same height.
– Unite the appliances using the special union
joint-coverings supplied upon request.
Connection to the gas piping
– Before carrying out the connection consult the
gas delivery body.
– Install a fast-closing cut-off cock upstream from
the appliance in an easily accessible place.
– Check if the appliance is set for the type of gas
with which it will be fed. If it is not, read
paragraph “Adaptation to another type of gas”.
– Check for any leaks in the connection points.
CONVERSION TO ANOTHER TYPE OF GAS
To adapt appliances to work with other tyes of gas
carry out all the operations stated below.
Nozzles, minimum adjustment screws and adhesive
labels are in the bag supplied with the appliance.
Replacement of burner nozzles (Fig. 3)
– Remove front panel of appliance.
– Remove the nozzle-support manifold RU.
– Unscrew nozzles and change them with the
proper ones according to Table T1.
Burner primary air adjustment (Fig. 3)
– Remove front panel of appliance.
– Operating on the shutters adjust primary air inlet
at the distance “A” indicated on Table T1.
12/31 Gas heated Fry-Tops and sloped Grillplates (FTG/BIG)
– Defective piezoelectric igniter, ignition spark
plug or cable.
Extinction of pilot burner flame during operation
– Gas inlet pressure drop
– Defective or insufficiently heated thermocouple,
or poorly connected to the gas cock.
– Defective gas cock.
– Defective or intervention of safety thermostat
(models with chromed plate).
Extinction of main burner flame during operation
– Gas inlet pressure drop
– Defective or insufficiently heated thermocouple,
or poorly connected to the gas cock.
– Defective gas cock.

REPLACEMENT OF PARTS SUBJECT TO CHANGE
Sealed components must not be tampered
with.
After each intervention, if necessary, check
for the absence of gas leaks.
Burner, Pilotburner, Thermocouple, Ignition spark
plug, Safety thermostat
– Remove control panel of appliance and replace
the component.

USE AND MAINTENANCE
WARNINGS
The appliance is for professional use and must be
used by trained personnel. The appliance has to be
used only for direct cooking of food, laying the food
to be cooked (meat, hamburger, fish, vegetables,
etc.) directly on the hot surface of the plate. Any
other use of the appliance is considered improper.
It is absolutely forbidden to use the plate for
indirect cooking of food, laying pots casseroles
or pans containing food on the plate.
The installation and adaptation to other types of gas
must be done by qualified and authorized installers.
In case of breakdown close the gas cut-off cock
upstream from the appliance.
Sealed components must not be tampered with.
For repairs consult only authorized service centres
and ask for original spare parts only.
The manufacturer declines any responsability
if such obligations are not observed.
Carefully read this booklet and keep it in a safe place.
Before using the appliance carefully clean all the
surfaces that will come in contact with food.
Additional safety device
Appliances with chromed plate are provided with
an additional safety thermostat which operates
shutting off the outflow of gas when, for any
failure, the cooking plate exceeds maximum temperature allowed. If this event occurs close the gas
cut-off cock and call for a authorized technician.
