For installation, use chalk or a laser level to mark the bottom of the flange at the required on-center spacing. Use the flange legs to mark kerfs locations. Cut kerfs as marked and insert the ICFVL flange flush to the face of the ICF. After the concrete has cured, slip the appropriate ledger connector underneath the ledger and install eight screws partially into the ledger. Position the bottom of the ledger level to the chalk line or the laser and drive the screws through the wood and into the flange.
For steel ledger installation a ledger connector is not required. Position the bottom of the ledger to the chalk or laser line against the flange. Use four appropriate drill point screws through the ledger and into the flange. The screws should be evenly spaced and at least ½” (13mm) away from the edge of the flange.
