4.4 Installing the GCU compact
4.4.1 Selecting the installation site
The installation site of the GCU compact must meet the minimum re-
quirements below (see also
Chap. 1.2.3 ).
Installation area
▪ The base must be level and smooth and have sufficient ground
load-bearing capacity of 1050 kg/m² plus safety factor. Install a
pedestal if necessary.
▪ Observe the installation dimensions (see Chap. 4.1 ).
Installation room
▪ There are no special conditions for ventilation of the installation
room for ambient air-independent operation (using a concentric
air/flue gas system).
▪ In partial ambient air-independent and ambient-dependent mode,
the installation room must have a ventilation opening of at least
150 cm
2
to the outside. If the flue gas line is routed to the outside
through an installation shaft, it must be rear-ventilated
(see
Chap. 4.2.2 ).
