5.3.1 Notes for installation location
Caution
Danger of damage from water!
The following must be observed when installing the EC four:
In order to prevent damage due to water, particularly due to leak­
ages in the DHW storage tank, suitable precautionary measures
should be taken regarding installation.
Installation room
The installation room must be dry, the room temperature must be be­
tween 0°C and 45°C.
The installation location has to be selected particularly with respect to
the routing of the flue gas pipes. When installing the boiler, the specified
wall clearances have to be maintained.
Along with the general rules of the technology, especially the regulations
of the federal German states, such as fire and construction ordinances
as well as heating room guidelines, must be observed. There should be
sufficient space in front of the equipment to carry out inspection and
maintenance work.
Caution
Risk of damage to the device!
Aggressive foreign substances in the combustion supply air can
destroy or damage the heat generator. Therefore installation in
rooms with high humidity (see also "Operation in wet rooms") or
heavy dust accumulation is only allowed with
room air independent operating modes.
If the EC four is operated in rooms in which solvents, cleaning
agents containing chlorine, paints, glues or similar substances are
worked with or in which such substances are stored, only room air
independent operation is permissible. This applies especially for
rooms in which ammonia and its compounds are heavily used, as
well as nitrites and sulphides (animal breeding and recycling facili­
ties, battery and galvanising rooms, etc.).
During the installation of the EC four under these conditions DIN
50929 (Corrosion probability of metallic materials with external
corrosion loading) as well as information sheet i. 158; “German
Copper Institute” is heeded.
Caution
Risk of damage to the device!
Furthermore it is to be observed that under aggressive atmos­
pheres even installations outside the boiler can be corroded. This
particularly includes aluminium, brass and copper installations.
These must be replaced by plastic-coated pipes in the factory in
accordance with DIN 30672. Fittings, pipe joints and shaped
pieces must be appropriately made from shrink tube in the per­
formance classes B and C.
For damages occurring due to the installation in an unsuitable location or
based on improper combustion air supply, no warranty claims may be
made.
