SECTION 15A: French & Pedestrian Door Installation
Note: C-Thru offers three types of doors: pedestrian (single). French (double), and sliding doors (Figure 15.1). The pedestrian and French doors have similar installation procedures. Refer to section 15B for the sliding door installation.
Note: The C-Thru Layout Sheet will note if the door(s) swing in or out. The raised section of the doorjamb should be placed opposite the direction door's swing.
15A-1. Assembling the French Doorjamb
The French doorjamb will arrive in four pre-cut sections: vertical doorjamb (2 pieces), horizontal doorjamb, and threshold. The horizontal and vertical jambs are miter-cut at 45-degrees and will be joined together with two "L"
brackets per corner. Use a mallet to press-fit the "L" brackets on the horizontal doorjamb. Mate the vertical
doorjambs with the horizontal pieces until they form a tight seam at their juncture (Figure 15.2).
15A-2. Adding a Female Extrusion Above the Doorjamb or Sliding Door
A female extrusion will be used for the transition between the top doorjamb and the transom. Measure the width
of the assembled doorjamb. Deduct 3/4" from this length and cut a section of female extrusion to this length.
Center this female on the top of the doorjamb. Do not fasten the female yet.
15A-3. Installing the Threshold
Note: in extreme circumstances (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 off legs of the bottom track. The bump-out on the threshold must be notched on both ends to accept the bump-outs on the vertical door jambs (Figure 15.3). Place the bottom threshold over the bottom track, make sure it is level, and fasten it to the bottom track with the provided fasteners.
15A-4. Installing the First Utility Mullion
A complete utility mullion will be secured to each side of the doorframe. Determine the location of the doorframe on the C-Thru room 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 electrical header and the bottom track. Insert the assembled doorframe into the
opening.
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 female utility mullion to the other side to complete the utility mullion. See the C-Thru room layout sheet for proper UM and UF locations.
15A-5. Completing the Transom
Please refer to the appropriate side wall section of this manual to place glass transoms, glass trapezoids, or solid fill above the doorframe.
15A-6. Installing the Second Utility Mullion and Securing the Doorframe
Place the second utility mullion on the opposite side and slide the doorframe into the opening. Make sure it is level. Fasten the utility mullion to the header beam and the bottom track. Making sure that the doorframe is level, secure it to the utility mullions with Pop rivets or #8 x 1/2" tek screws spaced every 16".
15A-7. Installing the Roton Hinge
Measure the height of the doorjamb and deduct 3/8". Cut the hinge to this length. Center the hinge on the doorjamb and fasten it with #10 x 1-1/2" tek screws provided in the door kit.
15A-8. Installing the Door Hinge Channel
Cut the hinge channel to the length of the door, and attach it to the doorjamb using #12 x 1/2" tek screws.
15A-9. Installing the Beauty Cap
The door with the locking hardware will have a beauty cap to cover the channel of the door. Snap this cover into place (Figure 15.5). This piece will generally be longer that the door and will need to be centered and trimmed.
15A-10. Installing the Door(s)
Note: Make sure to install the door in the proper direction direction. The glazing clips on the glass must always be on the outside of the room.
Slide the door into the hinge channel, and placed the door in the "closed" position. Make sure the gap around sides and the top of the door is even. Place shims underneath the door until the top of the door is spacedapproximately 3/8" from the door jamb. For French doors, leave a gap to account for the astragal that will beplaced on the non-operable door. Secure the hinge channel to the door on both sides with Pop rivets or #8 x1/2" tek screws spaced every 16". Repeat this process for the other door, if necessary for double pedestriandoor installations. See Figure 15.6 for the completed door attachment.
15A-11. Installing the Bottom Adjustment Channel
Measure from the edge of the door to the edge of the hinge channel, and cut a section of hinge channel to thislength. Place it onto the bottom of the door. This will be the bottom adjustment channel. Close the door, andslide this channel down until there is a 3/8" gap between the bottom adjustment channel and the threshold(Figure 15.7). Fasten this channel into place.
15A-12. Installing the Locking Astragal (French Doors Only)
The astragal is the unit that locks the fixed door in place with a set of pins. It is secured to the locked side of thetwo doors. Remove the rubber cap s from both ends. Cut out a 1" tall by 1-1/4” deep notch on the back sectionof the astragal on both the top and tthe bottom so it will fit around the raised section of the doorjamb and thethreshold when the door is closed (Figure 15.8). Attach the astragal to the door with #8 x 3/4" tek screws every
16". With the door in the "closed" position, slide the locking pins up to the door jamb and down to the threshold.
Mark these two locations and drill a 1/4" hole where the pins will slide into place.
