Conversion and adaptation
Changing the gas supply - Conversion
If the gas supply to the room where the appliance is to
be installed is different from the gas it is set up for, the
appliance must be converted from one type of gas to
another, e.g. from natural gas to LPG. In this case, the
nozzles of the main burner, the by-pass and the pilot
light need to be changed.
All the nozzles are marked with a number that indicates the
diameter in 1/100, and are supplied in a bag.
After each conversion or adaptation, the appliance must
undergo an operating test and the supplementary plate
must be updated according to the conversion or
adaptation carried out.

and apply a light layer of liquid paraffin.
What to do in the event of a malfunction
Malfunctions are not always caused by the quality of the
components used. These appliances are manufactured using top
quality components.
Failures may be caused by dust and dirt infiltrating the operating
components.
Unauthorised persons should never attempt to repair the appliance or carry out maintenance.
Tampering with the appliance voids the warranty.
If you suspect that there may be a fault, close the shut-off cock and inform the authorised
support service

Operational checks
THERMAL CAPACITY
Check that the gas type and group where the unit is to be used is
the same as that indicated on the plate. If it is not, follow the
conversion or adaptation procedure in the section “Conversion
and adaptation”.
Check that the right nozzles have been installed. Refer to the
nozzle table and check that the nozzles indicated in the table are
the same as those installed on the unit. As an additional check of
the thermal capacity, verify the gas consumed using the
volumetric method: start the burner and, after approximately 10
minutes (in working conditions), check that the gas flow (in m3/h
or in kg/h) corresponds to that in the nozzles table.
FLAME APPEARANCE AND PRIMARY AIRFLOW
Use the inspection hole “I” (fig.2) to check the flame.
The flame should be blue and there should be no yellow dots in
it; it must be stable at the base. If the colour of the flame is yellow,
it means the primary airflow is not adjusted properly. If the
primary airflow is too fast, the flame will be short and tend to burn
above the burner. The primary air capacity is fixed, therefore no
adjustment is required. The appearance of the flame must also be
checked 15 minutes after the appliance has been running at full
power. The flame must remain stable even when passing quickly
from minimum to maximum.
Any alterations made to the installation area
which may influence the amount of air needed
for combustion require appliance operation to
be checked again. When these checks have
been completed, test the appliance for leaks.

Maintenance and cleaning
Cleaning and care
Cleaning operations must only be
carried out once the appliance has
cooled.
Only use products that are food safe.
To clean the appliance, disassemble it as per the steps shown in
figs “14” to “18”.
Keeping the appliance clean is very important for a long and
trouble-free product life. Wash the removable parts separately
with warm water and detergent, then rinse them under running
water. Do not use harsh or abrasive detergents to clean the
stainless steel parts. Iron cleaning pads should not be used as
they may cause rust to form. For the same reason, avoid contact
with ferrous materials.
When cleaning, avoid using abrasive paper or cloth; instead, and
only in special cases, use pumice stone powder. For stubborn
deposits, use a sponge (e.g. Scotch-Brite). You can also use oven
and grill cleaning sprays, readily available on the market, to
remove stubborn deposits.
If you use spray products, please follow the manufacturer’s
instructions.
To minimise emissions of polluting substances into the
environment, clean the appliance with products that are at least
90% biodegradable.
Additional recommendations for cleaning, for gas grills only
Before turning on the appliance, frequent checks and cleaning of the inside of the appliance
are recommended. This is to prevent oil and grease residues from previous cooking being
burned.
For lava stone grills:
•Clean the burner holes regularly with a metal brush to prevent clogging and promote
good combustion;
•Remember that the lava stones must be distributed on the metal grid as uniformly as
possible, noting the following amounts:
GR35G/G6 - GR35G/0 - GR35G7
GR70G/G6 – GR70G/0 - GR70G7
