- In case of failed ignition, automatic ignition sequence is repeated 5 times. If all ignition trials are
failed, flame failure lockout happens. Error LED (red) will turn ON and blink to indicate this error
condition (fig.22). Turn Status ’s knob to the reset “
” position and hold it for 5 sec. to get to the
normal operation again If the lockout condition continues after reset read the Fault/Error finding.
- Turn the Status Pot. to ‘ OFF-Reset ’ position to shut off the boiler. LCD backlight will turn OFF.
CH (Central Heating) Mode
By adjusting the CH , summer mode or winter mode can be selected.
a) Summer mode
- Rotate the CH to the ‘
’ position. In the summer mode, any CH heat demands can not be satisfied.
The summer mode is only to satisfy domestic hot water demand.
b) Winter mode
- Rotate the CH to the ‘ ’ position. In the winter mode, your appliance satisfies central heating and
also domestic hot water.
- Adjust any CH water flow temperature between 40 and 80 oC with the Central Heating . The boiler
will modulate to the desired temperature. CH symbol on the LCD indicates that CH is active. If there
is a DHW request, it interrupts the CH mode until DHW request is finished.

- Rotate the CH to minumum position. The summer mode will be active and the system will go back
to stand-by mode again.
Frost Protection
The appliance goes on and off automatically depending on actual water temperature values measured
by the sensors for protecting water circuits against freezing. This function protects both CH and DHW
systems. Frost protection has 2 level:
a) Frost protection level 1
- When the appliance in stand-by mode and the CH sensor measures a low water temperature in the
system (less than 8 °C ), the pump runs. When the CH water temperature goes above 10 °C (measured
on the CH sensor), the pump will stop.
b) Frost protection level 2
- When the appliance in stand-by mode and the CH sensor measures a low water temperature in the
system (less than 6 °C ), the boiler starts as if there was a CH demand. When the CH water
temperature goes above 15 °C (measured on the CH sensor), the CH demand will end (burner will be
off). During frost protection the burner will run with minimum capacity.
- The same situation occurs when DHW sensor measures less than 6 °C. The boiler starts and when
the water temperature goes above 15 °C, the boiler will turn stand-by mode.
: The appliance must be on stand-by mode to activate frost protection
system.
Pump Anti-Seize Function
Anti-seize protection’s function prevents the pump from probable blocking when the pump stays
inactive for a long period of time. This function goes on automatically if the pump has been inactive
for at least 24 hours and runs the pump for 5 sn. in CH mode. In monothermic types, pump anti-seize
function and 3-way valve protection becomes active together and the 3-way valve changes
position against blocking.

GAS TYPE CONVERSION
: Gas type conversion from LPG to natural gas or from natural gas toLPG
must be carried out only by qualified person.
-
Gas type conversion can be divided in 3 sections: 1-gas pressure adjustments, 2- replacement
of the burner injectors and 3-changing the parameter of the gas type (00-NG or 01-LPG).
26
Page 28
Gas Pressure Adjustments
The operating pressure varies depending on the type of gas. Therefore, minumum and maximum
operating gas pressure must be set by means of the adjusment screws that are on top of the gas valve.
The heat output directly depends on the operating pressure. When the operating gas pressure range is
adjusted, minimum and maximum heat output is also adjusted (mechanically).
- Firstly, operate the boiler at maximum load while adjusting maximum operating pressure and
operate the boiler at minimum load while adjusting minumum operating pressure.
- Undo the 2 screws which are located on the lower edge to remove the front panel.
- Undo the 2 screws which are located on the corners of the control panel.
- Pull the control panel outwards to reach the gas valve.
Maximum operating pressure adjustment:
- Operate the boiler at maximum load.
- Connect the tube of a clocking gas meter to outlet pressure tap whose diameter is =9 mm
after loosening the tap’s screw.
(fig. 22)
- Remove cap screw from maximum pressure regu lator to expose pressure regulator adjusment screw
which is seen as (2) in fig. 22.
- Turn the adjustment screw clockwise to increase or counter-clockwise to decrease gas flow to the
burner.
- Check gas pressure measurements on the gas meter to satisfy the desired value.
In LPG operation, the adjustment screw (2) is tightened to the end for 28 / 35 supply pressure.
Minimum operating pressure adjustment:
- Operate the boiler at minimum load.
- Connect the tube of a clocking gas meter to the outlet pressure tap.
- Turn the adjustment screw which is seen as (1) in fig. 22 counter-clockwise to increase or clockwise
to decrease gas flow to the burner.
- Check gas pressure measurements on the gas meter to satisfy the desired value.
- Ensure that the tap’s screw is tightened after making the adjustments.
- Replace pressure regulator cap screw.
- Reassemble the front panel and the control panel.
