7.1- Selection of Device’s Assembly Location
The location where the device can be assembled and spaces to be left around it for safety,
service, maintenance, and use purposes must be as shown in Figure 10.
Figure 10: Indicates the minimum spaces to be left from the top and sides ofthe device
(Dimensions are given in mm).
For correct service and maintenance of the combi boiler, the installation should be carried out in
accordance with the following minimum spaces. The position of the combi boiler must be checked in
accordance with the technical rules.
15

Figure 10- Required spaces for the assembly of the device
- The device can not be used at altitudes higher than 2000 m above sea level.
- There is no need to remove side panels for the inside combi boiler service operations. Min. 50
mm spaces are given by considering a possible side panel sheet replacement.
- Do not assemble your combi boiler in places where it will be exposed to direct sunlight. Sun
exposure can cause discoloration on the outer surface of your device over time.
- The ambient temperature of the device’s assembly location must be between 5 - 35 °C.
- The device must not be assembled outdoors.
- The device must not be assembled on devices with a direct steam outlet.
- The device must not be assembled in areas where it can be at risk of direct water exposure.
- The device must not be assembled on damp places such as bathtubs, shower cabinets and
must be assembled at least 50 cm away from these areas.
- Since the outer surface temperature of the device does not exceed 85°C at maximum heating
power, no special protective measures are required for combustible building materials and
components.

7.2- Wall Mounting of the Device
After determining the place where the combi boiler is mounted:
• Using the assembly template (Page 30 - 31) in the user manual of the device, the locations of
the fixing screws of the wall bracket and the mounting bracket are marked.
• After the marked points are drilled, the wall bracket and mounting bracket are securely fixed to
the wall with the dowel and fixing screws included in the packaging of the device.
• Finally, the bracket on the rear surface of the combi boiler is placed on the hooks on the
bracket that you mounted on the wall and then the combi boiler is hanged on the wall.

8- CONNECTIONS
8.1- Water Pipe Connections
-The water connections between the wall mounting bracket fixed on the wall and the combi
boiler are made with the pipe group and nipples as shown in the figure.
8.1.1- MT Model
a) Central heating pipe 3/4" outlet line (hot)
b) Domestic water pipe 1/2" outlet line (hot)
c) Domestic water pipe 1/2" inlet line (cold)
d) Central heating pipe 3/4" return line (cold)
- A suitable sized valve should be
installed in the water pipelines. In
addition, a strainer must be
placed in the domestic water
(1/2") pipe inlet line and central
heating (3/4") pipe return line.
- The hose from the 3-bar safety
valve must be connected to the
sewage drain line.

DANGER: When making the electrical connection ofthe device, besure that there is no
voltage in the power line.
DANGER: If the supply cable isdamaged, it must bereplaced bythe
manufacturer, or anauthorized service or anequivalent qualified person.
CAUTION: Power supply line of the device must be protected by a residual current device
with 30 mAtripping sensitivity.
CAUTION: The electrical connection of yourdevice must be made according to the cable
sections in the table.
CAUTION: There is a circuit breaker placed in the device for overcurrent protection. Incase
the circuit breaker trips, call an authorized service
8.2- Electrical Connection
Your combi boiler must be connected to a grounded power line that can supply 230 VAC 50 Hz
voltage for single-phase devices and 400 VAC 50 Hz voltage for 3-phase devices. Malfunctions
caused by voltage fluctuations are not covered by the warranty.
CAUTION: Only 6, 9 and 12 kW models are suitable
for single phase operation.
CAUTION: For single-phase operation of the device,
you can connect the live wire of the supply cord to
the middle pole of the circuit breaker and bridge to
the other poles of the circuit breaker by the bridging
bar supplied with the product.
Figure 15. Device Mains Connections
19

CAUTION: For single-phase operation, a power supply
cord with suitable cross section defined for single-
phase operation must be used.
CAUTION: Bridging bar must not be used in 3-phase operation.
CAUTION: Malfunctions caused by power supply grid are not associated with the
device and are not covered by warranty.
