Determine width of first Channel. To ensure you will be able to fit the first and last Channels, you will need to determine the partial width of the first Channel. See our example calculation at right.
The first Channel will need to be cut lengthwise to fit into the Edge Trim. Be sure to leave enough room for the gutter system. The channels should extend into the gutter by at least 2″. This is needed to keep water from “wicking” back. The Channel length should also be equal to the total length of the Edge Trim. Mark the width, as determined by your calculations on the first Channel from the inner edge of the “U” (See fig “FIRST CHANNEL”). You will be cutting off the “Arrow”. Rip cut the first Channel and remove any sharp edges or burrs.
Install the first Channel. Starting near the ledger board, slide the first Channel between the 2 legs on the Edge Trim. Continue to push the first Channel into the Edge Trim until it is completely seated in place. Leave about 1/8″ gap between your main structure, under the ledger board, for the C-Channel. Snap the “U” of the first Channel into a Glide Clip on each Starter Strip.
Once the first Channel is installed, cut 2 full channels to length and install. Start near the ledger board and engage the “Arrow” into the “U” (See fig “FULL CHANNEL”). Snap the “U” into additional Glide Clips. Keep the end of each Channel 1/8″ away from the main structure, under the ledger board.
Once you reach the last Channel, measure the distance between the “U” on your last full installed Channel and the fascia trim board, subtract 1/4″, then cut the last Channel to length. Mark the last Channel from the “Arrow”, you will be removing the “U” part of the Channel. (See fig “LAST CHANNEL”). Rip cut the last Channel and remove any sharp edges and burrs. Insert the last Channel between the 2 legs on the Edge Trim. Insert the “Arrow” into the last full Channel to complete your UpSide installation.
