ATTENTION! The installation of appliance must be only executed by qualified service or specialist
authorized by retailer. The 2 years guarantee of appliance can be ensured only in this case.
Before putting operation of appliance the leak-proof/pressure test of gas supply system must be fulfilled.
• Clean duct system of gas supply from any contamination�
• Check the presence and cleanness of gas filter located before the appliance
• Check the presence and suitability of pressure regulator located centrally or before every appliance�( the pressure regulator
is needed if the gas supply pressure is higher than 60 mbar,in this way the capacity of pressure regulator can be max� 60
mbar)
• Make sure of protective ground of appliance�
• Check the proper electrical connection of temperature regulator�
• Open the gas supply valve�
• Check the gas pressure on the inlet side of solenoid valve�(the maximum allowed pressure is 60 mbar)�
• Connect the mains voltage to the appliance (by temperature regulator or central stage main-switch)�
• Check the outlet pressure of solenoid valve,whether the set up pressure – nozz le pressure – is suitable for the type of gas�
• At Natural gas – depending on output: 8�6, 9�5 or 10 mbar
• At „S” gas – depending on output: 8�6, 10, 11, 11�8, or 12�5 mbar
• At Propane and butane: 24�9 mbar

Appliance operation
Following the switched on voltage the fan operates continuously assuring the 30 seconds pre-purge time� This time period ensures the
three times air change of combustion volume in case of biggest appliance’s power�
When the pressure is suitable - after 30 seconds – the sparking happens and the solenoid valve opens in this way the gas catches fire�
In case during 5 seconds sparking(ignition) the continuous flame shape is stabilized, - and stable electrical signal is come back from the
electrode – the appliance operates and the green control lamp is lighting� During operation of appliance its automatic burner control con-
trols the condition of differential pressure switch and signals coming from the flame control continuously, and if the position of differential
pressure switch is changed – it is switched over from work position to rest – or the signal from the ionization flame control is interrupted
then it stops the gas supply of burner and the appliance gets into error position and red control lamp is lighting placed on the bottom side
of appliance�
If the flame control of burner automation does not register flame during the safety time than repeats the all ignition procedure
maximum two times. If in this time there is not registered flame then it stops the gas supply of burner and the appliance gets into error
position and red control lamp is lighting�
In case during burning process the pressure decreases under the permissible minimal
value on the positive side of air pressure(from the fan side),then automation prohibits:
- gas supply and fan stops
The appliance stands into error position and red control lamp is lighting�
Restart is possible after the switching off and on of mains voltage.
In case during burning process the pressure increases above the permissible maximum value on the negative side of air pressure switch
(from the burner tube side, eg� at combustion back),then it switches back to rest position and the automation prohibits�
- gas supply and fan stops
The appliance stands into error position and red control lamp is lighting�
Restart is possible after the switching off and on of mains voltage �
