4.2.1
Boiler room
One or more boilers with a combined load less than 130 kW maximum
can, if required, be located in a boiler or operations room. A cascade sys
tem with a total maximum load of more than 130 kW must comply with the
regulations that apply to boiler rooms.

Lifting aids
AD-0000138-03
Select the desired combination of boilers on the basis of the required heat
output. We advise leaving 1 m of free space at the front of the units. The
distance between individual boilers is 3 cm. A wall bracket is supplied for
wall-mounted linear configurations. This must be mounted at a height as
specified in the installation manual supplied with the cascade system. We
recommend a clearance of at least 50 cm above the units. This distance
also depends on any installation of flue gas outlet and air supply collector
pipes. Consult the flue gas tables.
The weight of the MCA 160 boiler exceeds the maximum lift weight for one
person. We recommend the use of a lifting aid.

General
The cascade systems can be divided into 3 main groups:
2 to 8 boilers in a linear configuration, wall mounted (LW)
2 to 8 boilers in a linear configuration, mounted on a free-standing frame
(LV)
3 to 8 boilers in a back-to-back configuration, mounted on a free-stand
ing frame (RG)
For each main group, the first listing is a sample configuration for two MCA
160 boilers and one MCA 45-115 boiler. Of course, many more configura
tions are possible but they would be too numerous to include in this techni
cal information.
