4 Inspection
opening
Maintenance opening with class EI
2
90-C fire resistance rating (e.g. chimney
door) immediately over the hole in the wall for easy clearance of any
blockages from oversized material around the shear edge of the discharge
screw. The inspection opening must be designed in such a way that it can
only be opened with a tool. The operator must highlight residual risks at the
inspection opening.
5 Side wall
protection
If the structure of the store means that the arms come into contact with the
wall (rectangular room), we recommend that you fit an approx. 300 mm
high covering made of sheet metal or hardwood to the wall of the store.
This prevents pieces of the wall and plaster from breaking off and blocking
the discharge system.
6 Raised
floor
This prevents material from remaining below the rotary agitator arms. This
material would decay, and this could affect the heating value. For this
reason, we recommend that the customer installs a raised floor. The
construction should be dimensioned so that the raised floor is not deformed
under the static load of the fuel. The raised floor must also be self-
supporting, and it should not be supported by the screw channel.

Before installing the rotary agitator, the customer must provide a wall penetration for
the trough. The dimensions of the opening are calculated from the wall thickness (s)
and the angle of the trough to the wall (β) or the angle of inclination (α) of the entire
system. Experience indicates that an opening of 500 mm x 500 mm is sufficient. You
should also note that the trough must not be connected to the wall, and that it should
be cladded in elastic at the end.
