Using lid support
For fire protection ducts of type BSKM 1025, it is necessary to insert a lid
support BSKM-DS 1025 (7216474) at every connection point. Due to the
250 mm width of the duct, the lid support is required in order to guarantee
tightness at the connection with the duct connector or the fitting if there is
a fire.
Note!
Mounting the lid support is only necessary if the lid is mounted on the
duct base from above. In the case of direct ceiling mounting, the lid sup-
port does not need to be mounted.
See Fig. 15:
•
Insert the lid support into the duct (1 ) and turn it (2 ).
•
Fold the lid support down (3 ).
•
If necessary, push it so that it is located in the middle of the connec-
tion point.
•
Together with the end piece BSKM-VK 1025 (7216460): push the lid
support so that it is flush with the end of the duct.
