After the installation make sure that the connections are properly fixed.
Never use open flame for checking the tightness of the gas pipes, only the
soap solution or special foaming product for leak detection.

- 39 -
Operation in case of gas consistent with the device preset
Check if the gas type specified on the rating plate conforms to the supplied gas type.
Correct data are specified in Table 1 “Use of gas categories and pressures in
various countries” on page 34.
In case of no data for the supplied gas type, gas category, or pressure for
comparing with the rating plate contact the local gas supplier.
CAUTION!
The device operates correctly only when the pressure in the gas system is
in range for different gas categories specified in Table 1 “Use of gas
categories and pressures in various countries” on page 34.
Main burner control
•Activate the device according to the instructions in section 5.2.3 “Ignition of gas
burners”, ignite the individual burners and see if the flame, ignition, and setting
of the smallest flame operate correctly. If not, check nozzles and setting of
primary air.
Changing the gas type / settings
CAUTION!
Change of gas type must be performed by the qualified gas installer.
•The device is designed and certified for operation with
the gas type specified on the rating plate (natural gas).
•When required, the device should be modified by the
qualified technician. In order to make modifications
replace the main burner nozzles (no. 2) and the ignition
burner (no. 1) and make required adjustments.
The delivery range includes nozzles for LPG.

a) Replacement of main burner nozzle
•In order to obtain access to the nozzles brackets remove the cast iron grates,
burners covers, burners bodies, and dripping trays.
•Unscrew the fixing bolt for the primary air adjustment.
•Replace the removed nozzle with the one designed for a given gas type (nozzle
data are in Table 2 “Properties of nozzles and burners” on page 35).
•Modify all burners according to the above instructions.
b) Replacement of ignition burner nozzle
•Use 11 mm wrench to unscrew the closing bolt of the ignition burner.
•Use the flat screwdriver to remove the ignition burner nozzle.
•Replace the removed nozzle with the one designed for a given gas type and
make required adjustments (nozzle data are in Table 2 “Properties of nozzles
and burners” on page 35).
•Modify all ignition burners according to the above instructions.
c) Setting of primary air
•Adjust the primary air according to Table 2 “Properties of nozzles and
burners” on page 35).
•When the primary air is adjusted correctly the flame is stable, so there will be no
interruptions when the burner is cold or back burning when the burner is hot.
d) Ignition burner adjustment
•Adjust the ignition burner and see if the flame is correct and covers the
thermal element. If not, see if correct nozzles are installed (Table 2
“Properties of nozzles and burners” on page 35).

- 41 -
e) Setting of the smallest flame
•After switching to the different gas type it is required to change the small flame
settings for the individual burners.
Adjust it in the following way:
•Ignite the burner according to the instructions in section 5.2.3 “Ignition of gas
burners”.
•Turn the flame adjustment knob clockwise to the small flame position “ “.
•Remove the adjustment knob.
•
When switching from the natural gas to LPG the fine
adjustment screw F(on the right) should be turned
clockwise with use of small screwdriver until obtaining
the required flame power.
•When switching from PLG to the natural gas the fine
adjustment screw F(on the right) should be turned
counterclockwise with use of small screwdriver until
obtaining the required flame power.
•Replace the knob and quickly turn it from the maximum position to the minimum
position and check the flame. Make sure that it still allows for correct heating of
the thermal element. If not, correct it. Make adjustments for all burners.
•After the replacement or adjustment of the nozzles always make sure that the
flame is blue, stable, does not separate from the burner, and there is no back
burning while changing from the large flame to the small one.
CAUTION!
•After switching to the different gas type always check tightness with use of
appropriate spray or water with soap (never use the open flame!).
•After all replacement or adjustment activities reinstall all previously removed
parts to make the device ready for operation.
•After the modification remove the plate with the adjustment values and replace
it with the new one for the new gas type.
