SECTION 15B: Sliding Door Installation

The sliding door frame will arrive assembled and be secured directly to the bottom track and utility mullions.

15B-1. Installing the First Utility Mullion
A complete utility mullion will be secured to each side of the sliding doorframe. Determine the location of the doorframe on the C-Thru roo layout sheet and mark the opening on the bottom track. The C-thru room layout sheet will also note which side the utility mullion male (UM) and female (UF) piece should be attached. At each end of the opening, measure from the inside lip of the bottom track to the bottom of the electrical header, and add 1". This will be the length of each utility mullion. Cut each utility mullion to the proper length. Making sure it is level fasten one utility mullion to the eletrical header and the bottom track. The sliding door also requires male extrusions on both sides of the door frame. Using this same procedure, cut to length male extrusions and fasten it to the utility mullion.

Note: if the wall modules have already been installed, they may have half of a utility mullion already attached to each module. Complete the utility mullion by attaching a male or femail utility mullion to the other side. See the C-Thru room layout sheet for proper UM and UF locations.

The opening for the vinyl door should be 1/8" larger than the door frame (approximately 71-5/8"). Plumb and secure the mullions on either side of the opening. Take diagonal measurements to make sure before the opening

15B-2. Raising of lowering the Threshold
A female extrusion must be placed on the bottom track to help support the sliding door. Trim the female extrusion to the length of the opening and fasten it to the bottom track with #8 x 1/2" tek screw every 18" (see Figure 15.10).

Note: In extreme circumstance (such as with an uneven slab or deck), it may be necessary to lower the threshold of the sliding door. Mark the position of the sliding door on the bottom track, and cut a notch in the bottom track as illustracted in Figure 15.11.

15B-3. Installing the Sliding Dorr Frame
Note: Installign the unit "upside down" will change the direction of the door opening.

Place the sliding door frame into the door frame from the outsidde of the room. Make sure it is square and level. Predrill 3/8" pilot holes through the first layer of the door frame (see Figure 15.12). DO NOT DRILL THROUGH THE ENTIRE DOOR FRAME

15B-4. Adding a Female Extrusion Above the Sliding Door
An "H" channel will be used for the transition between the top of the sliding door and the transom. Measure the width of the opening and cut a section of "H" channel to this length. Fasten this iece to the top of the sliding door frame as in Section 15B-3.

15B-5. Placing the Door Track, Screen Track, and Threshold
The door track, screen track, and threshold will need to be snapped into place in the bottom of the sliding door frame. Refer to Figure 15.13 for the correct placement of each piece.

15B-6. Installing the Door
Note: The sliding door contains two adjustable rollers o nthe top and the bottom of the door. These rollers are adjusted by the screws located on the sides of the door.

Note: The sliding door is punched on one side to accept the door hable and locking hardware. Make sure this side will sit next to the door frame when the door is closed.

Adjust the roolers on the bottom of the door so they protrude 1/4" from the frame. From the inside of the room, lift the door into the top of the door frame and down into the bottom of the door is plumb and it operates smoothly. Adjust the top rollers so that they rest snugly against the top of the door frame. Install the door hardware per the instructions supplied with the kit.
