Also, 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 should be soundly installed to building wall. Flexible connection
piece should be used between the combi and gas line. Flex lengths to be
used in A, B and C type devices should not exceed dimensions allowed by
local gas authorities. Flue outputs of hermetic combis 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,
• It is forbidden to install Hermetic combi (C type) to openings providing
clean air to other units!
2.2.3. Wall Installation of Combi and Selecting the Installation Place
• It should be controlled and ensured that the wall installation of the combi
is sound and reliable.
• The hanger plate given as standard with the combi 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 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 should be installed on a wall resistant to fire.
• NOTICE: Combustible and corrosive materials:
• Chemically aggressive substances can corrode the appliance and
invalidate any guarantee.
• Do not store or use any combustible materials (paper, thinners, paints,
propellants, cleaning agents etc.) Keep the distance minimum 50 mm.
• Inside the cupboard containing the appliance or within the vicinity of the
appliance.
• 1,8 - 2,2 m height is recommended for installation of the combi hanger
plate.
• For places with limited installation place, combi 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 intervention of the service
technician.
• Combi installation must not performed in environments containing
explosive, flammable substances and acid fumes
• Installation cannot be made at near or on ovens, radiators or heater
devices.
• Hermetic combis can be installed in furnitures but at least 5 cm each
should be left at both sides.
• If to be installed on the kitchen table or the set, at least 30 cm distance
should be left under the combi.
• 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
during installation. If this is not possible; do not place electronic devices,
delicate, corrodible devices, components and tools under the combi.
• Do not place/use any furnitures below the combi due to above mentioned
reasons.
Make sure that there are no liquids or inflammable materials in the
immediate vicinity of the boiler.
It is necessary to leave a spesific distance 1.0 mt between the
heating device and the building material containing combustible material
even the maximum allowable temperature value of 85 °C in the rated heat
capacity of the appliance is not exceeded.
