(10). To construct the side wall, measure from inside the starter channel to the inside of the outside wall. This is your exact length. The length of the 1 x 2 (10A) that goes inside the starter channel and next to the home, will be 3" less than the distance from the bottom lip of the header down to the concrete, and must be cut on a 5 degree angle on top. For this stud, use a 1 x 2 that has some adjustment room in case the home wall is out of level.
(11). The stud that goes against the outside wall stud will be 1 x 2, and its length will be 3" less than the inside height of the front wall. This stud must be cut on the short side with a 5 degree cut.
(12) To build the slant wall, you must first determine the length of the bottom plate. First measure from inside the receiving channel to the inside of the front wall, and subtract 1", and set into place, but do not fasten. Next, determine the top rail length. Measure from inside the receiving channel, along the bottom of the roof pan that is holding the front wall level, to the inside of the outside wall, subtract 1". Now add the long 1 x 2 stud that goes against the home. Add the short 1 x 2 stud that goes against the corner stud in the standing front wall. Next, put the top rail in position and let the short and long studs hold it up. Measure the length for your middle studs and cut them.
An easy way to determine these lengths is to use a 2 x 2 that extends past the 2 x 2 top rail. Stand this 2 x 2, making sure it is resting on the 1 x 2 bottom plate, where the stud is to be located. Now lean it against the top rail and level it. Next make a mark on the side of the 2 x 2 where it meets the underside of the top rail. Also mark the 2 x 2 as to where it goes, so you can pre-drill. (13). You can now remove the 2 x 2 and cut your angle according to your mark.
DOOR WALL: When measuring for the door opening, allow for a 38" opening on the bottom, between 1 x 2 bottom plates. This is necessary because you will be notching both 2 x 2 door studs on the bottom just like the front wall corner studs. Refer to illustration (20) for correct height of door studs. When both studs are notched and installed you will have the necessary 36" opening for your door.
Once the side wall frame is complete, stand and secure in the same manner as the outside wall.
To better secure that portion of the 2 x 2 (15) top rail that runs from the house out to the 2/3rds cut, use one or two #10 x 3" screws. Run these screws up from the bottom side of the top rail and into the overhang itself. Also, caulk both sides of the 2/3rds cut in the 2 x 2 top rail. If the header is attached to fascia, rather than the house wall itself, and there is an overhang, measure from wall of the house to the header. Now transfer that measurement to the 2 x 2 top rail and cut 2/3rds of the way through the 2 x 2 from the top, so it will bend and move up against the bottom of the overhang and header, and then pitch down to join the outside wall.
Note: Be sure before you install the kickplate rail that you check for low spots in the walls. When you find the lowest point, measure the height. This will be the uncut height the kickplate needs to be. You may have to cut down the kickplate coil to maintain this level the entire length. The height of the kickplate rail, from slab to top rail material, is 17" at the lowest point of the slab as indicated.
With room now standing and kickplate installed, the roof can be installed.
Note: Be sure the outside wall stays level from side to side while the roof is being installed.
STEP 5. Screen Door Installation
Before cutting the door jam, check slab (under the door area) for humps or anything unusual. If it is an inswing door, allow for possible carpet height.
Hold the door in place with the hinge side firm, and square with the 2 x 2. Put one screw in the face of the Z bar, by the top hinge, to hold the door in position.
(18A) Now attach the door with 2 screws in each hinge. Do not twist or bind the hinges. With the hinges firmly secured to the 2 x 2 (or wood frame) check for a smooth swing and effortless closing of the door. Install the pneumatic door closer, using the instructions supplied with the hardware set, and recheck for a smooth firm closing of the door. Make sure door studs have not been bowed before trimming screen.
