they may be installed at partially protected areas such as
balcony, terrace provided that being placed in protective
cabinets and taking required precautions against frost of
installation water.
Combi boiler should be soundly installed to building
wall. Flexible connection piece should be used between

allowed by local gas authorities. Flue outputs of hermetic
combi boilers must be connected to places open to
exterior and having air circulation. Installation (positions
of pipe output opening based on various forms, vertical,
horizontal minimum distances, cross section areas of
channels if given to channels, etc.) must be carried out
according to regulation standards, current legislation and
in compliance with local technical regulations and the
required technical procedures.
2.2.2. Places Not Suitable for Installing
Hermetical Combi Boilers
• Stairways of Buildings,
• Corridors available for general use, ventilation ways
and shafts, lofts, attics, emergency exit doors, cellars,
hall and similar places creating common use areas,
• Yards between buildings,
• Narrow cornice distances,
• Over flue walls,
• Enclosed balconies,
• Open balconies (except being located in the cabinet
and permission of the device company),
• Below protruding structure parts preventing exhaust
gas output,
• Places those may be directly subjected to wind
resistance,
• Openings providing clean air to other units!
2.2.3. Wall Installation of Combi Boiler and
Selecting the Installation Place
• It should be controlled and ensured that the wall
installation of the combi boiler is sound and reliable.
• The hanging plate given as standard with the combi
boiler should be installed according to the technique
to full or semi-full brick wall according to installation
scheme and with connection screws and not to be
used for other purposes.
• In case of using different materials for installation,
combi boiler shall be out of the warranty scope.
• If the wall of installation is not a brick wall, initially the
reliability of support system should be controlled.
• Combi boiler should be installed on a wall resistant to
fire.

*Minimum clearances required for servicing
• NOTICE: Combustible and corrosive materials:
a) Chemically aggressive substances can corrode the
appliance and invalidate any guarantee.
b) Do not store or use any combustible materials
(paper, thinners, paints, propellants, cleaning agents
etc.) Keep the distance minimum 50 cm.
c) 1,8 - 2,2 m height is recommended for installation of
the boiler hanging plate.
• For places with limited installation place, boiler should
be installed at minimum 30 cm height from ground and
by leaving at least 5 cm distances from both sides in
order to allow easy access of the service technician.
• Combi boiler installation must not performed in
environments containing explosive, flammable
substances and acid fumes
• Installation cannot be made near or above ovens,
radiators or heater devices.
• Hermetic combi boilers can be installed in furnitures
but at least 5 cm should be left at both sides.
• If to be installed above the kitchen countertops or the
set, at least 30 cm distance should be left under the
combi boiler.
• It is recommended to connect the output to drain
line with a transparent hose against the possibility
of water leakage from Safety Valve of combi boiler
during installation. If this is not possible; do not
place electronic devices, delicate, corrodible devices,
components and tools under the combi boiler.
• Do not place/use any furnitures below the combi boiler
due to above mentioned reasons.
Make sure that there are no liquids or
inflammable materials in the vicinity of the
boiler. It is necessary to leave a distance of 1.0
mt between the heating device and the building material
containing combustible material even though the
maximum allowable temperature value of 85 °C in the
rated heat capacity of the appliance is not exceeded.
