Notes for installation location
Caution
Install the boiler on a solid, stable structure able to bear its weight.
Caution
Danger of damage from water!
The following must be observed when installing the EC five:
In order to prevent damage due to water, particularly due to
leakages in the DHW storage tank, suitable precautionary
measures should be taken regarding installation.
Installation room
The installation room must be dry and frost-free.
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
Danger of damaging the device!
Aggressive foreign substances in the combustion supply air can
destroy or damage the heat generator. Therefore the installation in
rooms with heavy dust accumulation is only allowed with
room air independent operating modes.
If the EC five 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, nitrites and
sulphides are present (animal breeding and recycling facilities,
battery and galvanising rooms, etc.).
During the installation of the EC five 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.
For damages occurring due to the installation in an unsuitable location or
based on improper combustion air supply, there is no warranty claim.
5.9.2
Combustion air openings
Openings for the combustion air must be provided in the installation room
of the gas condensing boiler.
Room air-dependent operation
The required cross-sections for the combustion air openings with room air-
dependent operation are to be taken from the following table:
Model
EC five 400 kW
EC five 470 kW
EC five 540 kW
EC five 610 kW
