Control of the Nominal Heat Input:
During initial installation and during maintenance or adaptation to
another type of gas nominal heat input must be measured.
It can be measured using the volumetric method with the aid of a litre
counter or chronometer.
The appliance must be
supplied with one of the types
of gas whose properties and
pressure are set out in Tab. 1.
Checking Gas Pressure:
The supply gas pressure must be measured
at the height of the pressure outlet (Fig.7-8)
after removing the seal screws.
Use a exible pipe, connect a gauge to
the pressure point (e.g. a liquid manometer
with minimum resolution of 0.1 mbar)
and measure the inlet pressure whilst the
appliance is operating.
The pressure value must not be less than
the minimum limit indicated in Tab. 1.
If the value is not respected, switch o the appliance, disconnect the
gauge, close the seal screw and insert the washer, contact the gas

company to test main gas supply pressure. A pressure adjuster may
need to be inserted upstream of the appliance.
1.6 Transformation for use with Dierent Gas
If the appliance must be connected to a dierent type of gas than that
for which it has been prepared, the nozzles must be replaced.
Replacing the main burner nozzle:
Remove the front panel, unscrew the nozzle “G” (Fig.9) and replace
it with that corresponding to the pre-selected gas, according to that
stated on the technical plate. The nozzles are marked in hundredths of
a millimetre.
Replacing the pilot burner nozzle:
The pilot burner is accessible after the front
panel has been removed. Replace the nozzle
“D” (Fig.10), loosening the xing nut “E” and
mounting that relative to the type of gas with
which the machine is to be powered. Verify that
the ame envelops the thermocoupling and that
its appearance is correct.

Primary air regulation
The primary air is properly regulated if ame stability is ensured or, in
other words, if there are no breaks in the ame with the burner cold and
if there is no backring with the burner hot.
The distance envisioned for adjustment of the primary air is indicated
in Fig.9 and in Tab.4
Unscrew the injector “G” and install the one intended for the type of
gas, checking the distance “X” for the air.
When conversion or adaptation has been completed for every type of
gas, it is MANDATORY to ax the corresponding plate above the technical
plate, which is provided along with the nozzles.
Once operations to convert the gas type have been completed, check
the seal of removed parts using the bubble test or indicated foamy
substances. NEVER USE OPEN FLAMES to check for the presence of
gas leaks.
WARNING!
THE MANUFACTURER IS NOT RESPONSIBLE AND WILL NOT
COVER UNDER GUARANTEE DAMAGE CAUSED BY INCORRECT
INSTALLATION NOT FOLLOWING THE INSTRUCTIONS.
Adjustment of the reduced ow rate (versions in mild steel and compound)
To obtain reduced ow rate, loosen the screw “F”
(Fig.11).
Make sure the gas quantity is sucient to maintain
a stable and uniform minimum and resist switching to
maximum ow - minimum ow.

button until the pilot ame ignites. Ignition
can be observed through the peephole on
the instrument panel. Hold the knob down for
a further 15-20 seconds. If the ame should
go out when the knob is released, repeat the
operation;
• after having turned on the pilot, turn the knob
further to the left and adjust the intensity of the
ame in the MIN and MAX positions. Burners
ignition can be checked through the same
peephole used to check pilot ignition.
3.2.2 Switch-o
It is possible to switch o the main burner only by turning the knob
to the pilot ignition position .
In this way, only the pilot burner remains on.
If, instead, the knob is taken to the "O" position, the pilot burner also
switches o in addition to the main burner.

Ignition can be observed through the peephole on the instrument panel.
Hold the knob down for a further 15-20 seconds. If the ame should go
out when the knob is released, repeat the operation
Ignite the main burner:
When the pilot is ignited, proceed to ignite the main burner by turning
the temperature regulation knob to the desired degrees. Burners ignition
can be checked through the same peephole used to check pilot ignition.
3.3.2 Switch-o
It is possible to switch o the main burner only by turning the knob to
the pilot ignition position.
In this way, only the pilot burner remains on.
The main burner switches o when the temperature is reached or if it is
necessary to lower that initially set.
If the temperature regulation knob is moved to the "O" position, the
pilot burner also switches o in addition to the main burner, and the fry
top will stop working.
3.4 Emptying the drip tray
Regularly check the grease drip
tray located under the front control
panel.
Turn o the machine, empty the
tray by extracting it from the front
and take care not to burn yourself.
It can be washed in the dishwasher.
Before turning the fry top on
again, reposition the tray in its slot. Fig.15

4. MAINTENANCE and CLEANING
Disconnect the appliance from the gas supply before performing any
cleaning or maintenance operations.
At the end of the working day, clean the appliance, both for reasons of
hygiene and to prevent operating faults.
The appliance must never be cleaned with direct or high pressure
jets of water. Moreover, the appliance should not be cleaned with wire
sponges, ordinary steel brushes or scrapers; eventually, and only for the
steel parts, you can use stainless steel wool, wiping the appliance in the
direction of the sheet metal grain.
The top must be cleaned using
hot water and non-chlorine-based
detergents. It must never be cleaned
using steel wool, sandpaper or similar.
If dirtiness is accentuated, the use of
synthetic sponges is recommended
(e.g. Scotchbrite).
For non-stainless steel tops, it is
mandatory to dry the top and protect
it with cooking fat or oil to keep it in
excellent condition and prevent rusting.
If rust should form due to water, humidity and/or failure to protect the
top at the end of cooking, the rust must be removed to prevent corrosion
using stainless steel wool until the oxidised part has been polished. Wash,
dry and protect the top as described previously.
Make sure not to protect the top when wet or damp. In addition to being
pointless, this operation is damaging since rusting will increase under
the layer of protection!
After cleaning, rinse with clean water and dry using a cotton, wool or
linen cloth. Do not use synthetic materials.
All maintenance must be performed by qualied sta.
At least once per year, have the appliance fully checked, including an
assessment of the gas circuit seal and of the components in general.
All routine and special maintenance must be performed by qualied
personnel.
