¾ Fig. 4 indicates minumum clearances from the ceiling and the sides.
a) b)
fig. 4
- The appliance should be mounted against a closed wall.
- The outer surface of the water heater do not exceed 85 oC in maximum running mode so do not
take additional precautions againts constructional materials (combustible materials)
WARNING: Do not block the air vents which provide fresh air to the installation room.
WARNING: The water heater location and air/flue terminal position must obey
national and local requirements, gas safety regulations and relevant standarts.
¨ The water heater is not suitable for external installation. It should be within in the building.
- In case of gas leakage, it is necessary to vent the installation room according to national and local
requirements, although the water heaters are independent of room volume and ventilation.

¨ The air/flue terminal must be exposed to the external air and allow free passage of air cross it at
all times.
- The minimum acceptable dimensions from the terminal to obstructions and ventilation openings
must obey national and local requirements.
- The air/flue ducts should be fitted at a slight % 10 or 20 downwards incline to prevent any water or
condensation from entering the combustion chamber
Mounting Heater
Having determined the heater location,
- Use the paper template to mark out the positions of the fixing holes of wall and mounting
brackets.
- Drill the wall and fix the wall bracket to the wall with the 3 screws
- Hang up on the wall bracket.

appliance.
Open hot water tap to check the water circuit. Check any leakage water pipes.
Check whether flue kit is comprised of original parts or not according to the instructions and
regulations.
In addition,
¾ Electricity connections of the heater must be earthed and suitable with main supply conditions
(230 V AC - 50 Hz).
¾ Gas supply must be checked by the qualified gas company.
Call qualified service to heater start-up after all these processes are completed.
: The start-up must be performed certainly by qualified person.
: After the start-up, you should request information about operating
the water heater and safety precautions from qualified person.

Operating The Water Heater
Start up / Shut off
- To start up the water heater, turn the ON/OFF knob to ‘ ON ’ position (fig. 13a) and then set to
temperature control knob to desired temperature between Min. (35 0C) and Max. (60 0C) positions
(fig. 14).
fig. 13a fig. 13b
- In case of failed ignition, automatic ignition sequence is repeated 3 times. If all ignition trials are
failed, flame failure lockout happens and indicate this error condition (No flame signal, FL), read
the page of 19, Fault/Error finding.
- Turn the ON/OFF switch to ‘ OFF ’ position (fig. 13b) to shut off the water heater.
Temperature Control Knob
- The temperature control knob has the function to set the water temperature between 35 0 C and
60 0 C (fig. 14).
- Setting value appears on the LCD (blinks), after four seconds actual water temperature will appear
instead of the set value. The heater will modulate to the desired temperature.
fig. 14
- The reset procedure to reset the system from lockout (fig. 15)
• Turn the temperature control knob to the outside of the reset zone (in the adjustment zone).
• Turn the temperature control knob into the reset zone. Wait 1 second. Then turn the
temperature control knob again to the outside of the reset zone (in the adjustment zone).
After these operations, the reset procedure is completed. These actions must be carried out within a
maximum time of 5 seconds. If you are in the parameters menu the reset procedure is not active.
When the temperature control knob is in the reset zone, the set temperature is set to the minimum
set point (35
0
C) if the system is not in lockuot.

Frost Protection
The appliance goes on and off automatically depending on actual water temperature values
measured by the water temperature sensor for protecting water circuit against freezing.
- If the water sensor measures a low water temperature in the system (less than 5 °C ), the frost
protection is activated. When the water temperature goes above 15 °C (measured on the sensor), the
frost protection is deactivated.
: The electricity and gas valve must be open to activate the frost
protection.
GAS TYPE CONVERSION
: Gas type conversion from LPG to natural gas or from natural gas to LPG
must be carried out only by qualified person.
Gas Pressure Adjustments
The operating pressure varies depending on the type of gas. Therefore, minimum 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).
- First, operate the water heater at maximum load while adjusting maximum operating pressure and
operate the appliance at minimum load while adjusting minumum operating pressure. To reach the
gas Valve:
- Undo screw (A) securing the plastic lower
plate (B) then slide forward and remove it.
(fig.16)
- Remove the front panel, slide the plastic
control panel by pressing the secure tabs (1) to
the both sides and, pull downward the control
panel (fig.17a)
- Undo three screws (3) which are located on
the front panel and push the front panel up and
remove.(fig.17b - 17c) Pull the control panel
downward to reach the gas valve.
- The inlet gas pressure must be the nominal
pressure while performing the adjustment.
fig. 16

fig. 17a fig. 17b
¨ Maximum operating gas pressure
adjustment:
- Operate the water heater at maximum load (use
Parameter menu detailed in service manual).
- Connect the tube of a clocking gas meter to outlet
pressure measurement point (2) after loosening the
plastic adjusment cover (fig.18).
- Turn the brass screw (4) clockwise to increase the
gas outlet pressure (burner pressure) and turn to
counterclockwise to decrease the gas outlet
pressure.
- Check gas pressure measurements on the gas
meter to satisfy the desired value. In LPG
operation, maximum gas adjusment screw (4) is
tigtened to the end for 28 mbar supply pressure.
Fig.17c
fig.18
¨ Minimum operating gas pressure adjustment:
- Operate the water heater at minimum load (use Parameter menu detailed in service manual).
- Connect the tube of a clocking gas meter to outlet pressure measurement point (2).
- Turn the plastic srew (3) clocwise to increase the outlet gas pressure and turn the plastic screw
counterclockwise to decrease the outlet gas pressure.
- Ensure that the outlet pressure is correctly adjusted, check minimum and maximum setting several
times, then tighten the protective plastic (yellow) cover (fig.18).
- Reassemble the control panel, Plastic lower plate and front panel.

Replacement Of The Burner Injectors
WARNING: Keep the gas valve on the water heater and electricity supply closed
during replacement of the burner injectors.
- Shut off the water heater by turning the ON/OFF knob to OFF position and turn off the gas valve
on the gas circuit to the water heater.
- First, Undo screw (A) securing the plastic lower plate (B) then slide forward and remove it. (see
fig.16)
- To remove the front panel, slide the plastic control panel by pressing the secure tabs (1) to the both
sides and, pull downward the control panel (fig.17a)
- Undo two screws (3) which are located on the front panel and push the panel up and remove.
- Pull the control panel outwards (fig. 17b).
- Undo the 4 screws which fasten the manifold to the burner to remove the burner.
- Fix the suitable burner injectors according to type of gas (11 pieces of injectors used)
- Reassemble in the reverse order.

WARNING: In case of gas leak, fire or explosion hazard, property damage,
severe injury or death can happen. Therefore, gas leak test
must be performed by qualified person after gas type conversion.
¨
GAS LEAK TEST
¾ Apply a rich soap and water solution to the surface of all pipe connections. Bubbles indicate a
gas leak
¾ In case of gas leak, tighten the pipe connection.
¾ Check the pipe connection again for gas leak.
¾ Replace the part/parts if gas leak can not be stopped.
CAUTION: Keep soap and water solution away from electrical connections during
gas leak test.
Parameter Adjustment
Use Parameter menu detailed in service manual.
