1.Adjust the indoor temperature settings to your needs.
2. Having the heating operation set according to your intended use
will increase energy savings.
3. Savings can be made by adjusting the required temperature
value for each section (of the property with thermostatic
radiator valves), However, simultaneous use of a room
thermostat and thermostatic valves may cause problems.
4. It is important to position the room thermostat away from
objects, such as curtains, articles, etc., which could disrupt the
ambient airflow.. This will ensure that the device can correctly
detect the temperature.
5. The room thermostat should be located at a suitable height
and away from the Boiler and other devices that would affect
detection of the actual ambient temperature.
6. Long-term ventilation of the heated environments will
increases energy loss. Short-term ventilation should be
provided. If long-term ventilation is required, closing the
radiator valves or reducing the device temperature setting
saves energy.
7. Setting the boiler to a lower temperature overnight or when
not at home will save energy while maintaining the ambient
temperature.
8. Setting the operating temperature of the device according to
the outside temperature saves energy.
9. Setting domestic water temperature to a moderate level
saves energy.
2. RECOMMENDATIONS FOR ECONOMICAL USE

5. BOILER ASSEMBLY
5.1 Installation requirements and safety instructions
8

For ease of maintenance, observe the minimum distances
specified in the installation in order to access the boiler.
For correct device positioning:
•Do not place above a stove hob or similar cooking
appliances.
•Do not leave flammable products in the room where the
boiler is installed
•Heat-sensitive walls (eg wooden walls) need proper
insulation. Insulation must be installed between the wall and
boiler.
• Before installation, carefully flush all system piping to remove
any debris that may interfere with the operation of the boiler. In
case of leakage due to overpressure of the heating system,
place a water collection funnel with a suitable drain pipe under
the safety valve. There is no need for a safety valve in the
9

mains hot water circuit, but make sure that the water system
does not exceed 6 bars. If in doubt, have a pressure reducer
installed.
•The area where the boiler is installed must be free of
obstructions and protrusions during repair or maintenance.
•The electrical connection of the boiler must be made with
suitable cables, MCB/RCD and grounding must be installed.
• The wall on which your device is mounted must be strong enough
to bear the weight of the device.
The appliance must be installed exclusively on a vertical and solid
wall that can support the weight of the boiler. M8 screws with
appropriate anchors conforming to the type of the wall itself are
recommended.
Pipe of appropriate diameter to ensure adequate circulation of
the heating water must be used during installation. If the
correct diameter heating pipes are not used, constriction or
blockages in the installation may result in insufficient heating
circulation. Connections to the boiler should be easily
detachable if necessary. Non return Valves should be used
with the inlet pipes. Separate shut-off valves should be used at
the inlet and outlet of the heating circuit. A reducer valve
should be used at the boiler cold water inlet.

water outlet of the appliance. The air in the boiler will be
discharged from this tap.
Close the tap after the air has been discharged from the tap
and water has started to flow continuously.
Water leakage should be checked carefully.
The filling is done with the blue filling tap under the device.
This should be done following the instructions below.
Make sure the cold water inlet tap is open.
Open the filling tap until the water pressure gauge is between
1 and 1.5 bar.
When the filling is complete, close the filling tap.
Discharge air accumulated in the radiators.
•Heating water pressure should be checked to make sure that
it is between 1 and 1.5 bar after discharging the air in the
radiators .
•Check to ensure there is no water leakage.

5.2.2. The Electrical Connections
11

The electrical installation must be carried out by a qualified
electrician using suitable diameter cable determined according
to the boiler capacity and cable length. The MCB and RCD
with appropriate characteristics and amperage which can cut
the boiler electricity completely should be located separately
and be close to the device. If there is no earthing installation in
the structure where the boiler is installed, the grounding line for
the boiler should be installed by a qualified electrician. The
Isolator switch must be located near the boiler, and after the
Isolator switch there must be enough cable to connect to the
boiler. The connection of the cables to the boiler must be done
by a qualified installer. Cable diameters calculated according to
boiler capacity and cable lengths, and MCB and RCD
amperage values can be seen in the table below.
