Idle adjustment of the PEL 21 for thermostat models
(Fig. 2)
Consult the "BURNERS" table and adjust the low flame
screw (20) as follows:
- when using liquid gas, tighten the minimum
adjustment screw all the way down
- when using methane:
1 Locate the knob of the corresponding tap.
2 Turn the burner on and put it at the minimum output
position.
3 Adjust the minimum flow rate with screw 20 (Fig.
1-2). Unscrew to increase the flow rate and tighten
to decrease it.
4 Once the flame is judged as suitable for a minimum
setting, check that it corresponds to the minimum
flow indicated in the "TECHNICAL DATA" table.
The check must be carried out according to the
"volumetric method", described above, as follows
5 Read the gas counter and, at the same time, start the
stopwatch.
6 After quite long time, for example 10 minutes, stop
the 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;
- check that the gas exhaustion way is integral.
Whenever the main burner needs cleaning, proceed as
follows (Fig. 4A - 4B):
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 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).
Igniter plug (Fig. 5A - 5B)
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 5A - 5B)
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
START-UP
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
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.
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.
