D1H
D2H
Follow the instructions and perform the installation as depicted in the
figures and the details section.
1.
Prepare the duct connection or opening, clean and flatten the connecting surface.
2.
Apply fire resistive coat (6) on the connection surfaces.
3. Connect the damper to ductwork.
4. From boards (13) create collars and overlap the connection.
5. Fix the collar covering to the damper and ductwork with nails or pins as per duct system manufacturer instructions.
IMPORTANT:
Dimension of opening must be created according to details of each type and thickness of connected duct.
The fire resistivity of S-BM2 smoke control damper must be decreased to the duct performance.
The maximum resistivity for D1H, D2H installation is EI120S with pressure level 2 (-1000 Pa … 300 Pa)
