GAS LEAKAGE TEST:
• Apply the foam obtained by soapy water on all the gas pipe connections. Arise of bubbles indicates
gas leakage on the connection.
• In case of determination of gas leakage, tighten that connection, and recheck it by applying foam
on the connections.
• If the gas leakage persists, replace the seal (gasket) and/or connection pieces.
CAUTION: During gas leakage test, soapy water and foam should be
kept away from electrical connections.
DETERMINATION and RESOLUTION of ERRORS and MALFUNCTIONS
There are various controls for the safe operation of the device. In case of malfunctions during these
controls, or in case of abnormalities in monitored values, the device turns to error or malfunction
position. In that case, the malfunction codes defining the malfunctions will appear on the LCD display
and will warn you (Table 4).
The safety of your device has been provided in two ways.
1- Error Conditions (Locking)
2- Malfunction Conditions (Blocking)
In case of an error on your device, your device will turn to locking position. These errors are flue gas
excessive temperature locking, excessive temperature locking, no flame signal warning, flame loss
warning, flame circuit malfunction, water flow inspection warning, gas valve circuit malfunction and
fan speed malfunction. In that case, the error codes will appear on LCD display as seen on Table 4
and will inform the error. These errors are tried to be removed by pressing on the reset button. But
if it is recurring, the authorized service should be informed.
In order to re-operate your device in cases of locking;
- Press the reset button. The main board will be reset, and the device will turn to stand-by position.
And in case of a malfunction, your device will turn to blocked position. These malfunctions are
excessive temperature warning, CH exiting water sensor (NTC) malfunction, flue gas sensor (NTC)
malfunction, DHW sensor (NTC) malfunction, CH returning water sensor (NTC) malfunction, voltage
warning and low water pressure warning.
In cases of blockage, the malfunction can not be reset. For the re-operation of your device, it is
required to resolve the problem causing malfunction. For instance, in case a temperature value
exceeds the limit value, the system automatically resets after the value turns to normal after a while.
