If the fire/fire gas damper is not connected to the duct
system, e.g. when installing as a closing device or transfer air
device, the damper must be fitted with protection grilles on
the non-connected side. The minimum permissible distance

Check that the screws and the thermal sensor do not
hinder damper blade movement.
