stopwatch and read the gas counter again.
7- Calculate how much gas has passed in 10 minutes (the
difference between the two readings), for example 1st
reading - 2nd reading = 30 liters (0,03m³).
8- Now calculate the minimum power by applying the
volumetric method formula (previous paragraph).
Power (kw) = consumption (m³/h) for heating power of
methane
9- If the power is less than the table value, loosen the low
flame screw again and check again.
10- If the power is higher than the table value, tighten the
low flame screw again and check again. (9.45 kw/h). P
(kw) = 30 liters x 60/10 x 9.45 kw/h = 1.700 kw
MAINTENANCE
Attention!
Before affecting any maintenance or repair operation,
disconnect the appliance from the gas power supply.
The following maintenance program should be carried out
at least once a year:
- Check that all the safety and setting devices are working
properly;
- Check that the burners are working properly with regard
to:
• ignition;
• combustion safety;
- Check the various functions of the appliance by following
the procedure described in the "Checking the functions"
paragraph.
Whenever the main burner needs cleaning, proceed as
follows:
a) remove the control knobs, the gravy collection tray and
the control panel after having unscrewed the fixing
screws;
b) remove the gas pipe from the nozzle holder by unscrewing
the proper nipple (28);
c) remove the front sheet of the combustion chamber by
unscrewing the fixing screws and unloosing the fixing
screws of the sheet on the front side of the main burner.
The main burner can be removed to be cleaned. Carefully
clean all the burner outlets with a proper tool or a small
stick with the appropriate diameter. Make sure, when
reassembling the burner, that the back side is slotted
correctly in the combustion chamber.
- Check that there are no leakage along the gas exhaust
system line.
LIST AND REPLACEMENT OF RECOMMENDED PARTS
USE ONLY ORIGINAL SPARE PARTS SUPPLIED BY THE
MANUFACTURER. The parts must be replaced solely by
authorized personnel!
To replace the following pieces, first remove the control
knobs, the gravy collection tray and the control panel (after
having loosened the fixing screws).
ENGLISH
Igniter plug (Fig. 5)
Remove the igniter plug (37) from the bottom. Remove the
ignition cable, loosen the fixing nut and insert a new plug.
Gas tap (Fig. 1-2-3)
Loosen the nipples of the gas pipes and thermocouple, then
loosen the fixing screws of the supply to the gas pipe and
insert a new tap.
Thermocouple (Fig. 1-2-3 and 5)
Loosen the nipples that fix the thermocouple to the case
(taps, valves) of the gas and to the pilot burner and insert
the new piece.
After replacing, reassemble the control panel and the
relevant parties in the proper order.
WARNING
Every time a replacement involving gas input parts is
made, recheck all the functions and test for leakage.
USER'S INSTRUCTIONS
The appliance is strictly for professional use and must be
used by qualified personnel.
We recommend that the user make sure that the installation
was properly done. The manufacturer is not responsible for
damages due to an incorrect installation, bad maintenance
or incorrect use.
Before operating, CAREFULLY READ THE USE INSTRUCTIONS
WITHIN THIS MANUAL; pay particular attention to the
regulations relevant to the safety devices. Close all gas supply
cocks after use and, above all, during maintenance and repair
operations. Carefully follow the cooking instructions for at
least the initial period up to when practice and experience
will help you to personally choose a cooking time and
temperature.
Initial cooking with the griddle
Important!
Before using the appliance for the first time, carefully
clean the surface of the griddle with lukewarm water and
detergent, use a soft cloth to remove any trace of the anti-
rust product applied in the factory. Dry with a clean cloth.
Ignition of the pilot burner (Fig. 6)
Press the knob (4) and turn it left to its position. Keep the
knob pressed in and simultaneously press the button of the
piezoelectric ignition (6) up to when the pilot flame lights
up. Make sure the pilot flame is on through the slot (10) on
the control panel. Keep the knob pressed in for about 15-20
seconds; if the pilot flame turns off after releasing the knob,
repeat the ignition operation.
Main burner ignition and temperature regulation (Fig. 6)
To turn on the main burner, rotate the knob further to the
left up to the desired temperature.
