There are several ways to install a fire door. One of them—the most common—is using masonry anchors.
To install the assembly using the construction clamps:
> First, open the clamping arms to 90°. Prepare the opening by cutting out the recesses on-site where the clamping arms will later fit. Fig. 1.
> With the door panel closed and without removing the protective elements, install the assembly in the opening. For proper operation, the door must be square and perfectly plumb. Fig. 2.
> Cover the entire perimeter of the door frame with mortar or quick-setting cement, making sure it is thoroughly covered on both the outside and the inside.
> Once the bonding material has fully cured, remove the protective elements from the blade. Fig. 3.
> If you want to remove the lower stiffener, use a hammer and chisel to tap the welded joints where it connects to the frame to detach it.
> Finally, install the doorknobs and paint the walls.
Before completing the installation
> Verify that the installation was performed correctly and that the door is operating properly.
> Adjust the door, if necessary, so that it meets the installation clearances while adhering to the established tolerances.
> Perform proper periodic maintenance on the unit in accordance with the maintenance instructions.
