Instructions for Installation and Servicing
36
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 presense and suitability of pressure regulator located centrally or before every appliance.( the pressure regulator
is needed if the gas supply pressure is higher than 60mbar,in this way the capacity of pressure regulator can be max.60m-
bar)
•
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 60mbar).
•
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 vagy 10 mbar
•
At „S” gas – depending on output: 8.6, 10, 11, 11.8, vagy 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 prepurge 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.

direction of gas flow
Following the switched on voltage the fan operates continuously assuring the 30 seconds prepurge 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.
The flame sensor is self-monitoring and only performs an intervention on the burner it controls, insensitive to other environmental effects
(eg.: external heat, light)
