Schlüter®-Kerdi-Line

Installation

The following steps explain the Installation of the linear drainage systems. For detailed descriptions please refer to the Installation instructions for the following products:

  • Schlüter®-KERDI-LINE-H
  • Schlüter®-KERDI-LINE-H 50 G2
  • Schlüter®-KERDI-LINE-F
  • Schlüter®-KERDI-LINE-V
  • Schlüter®-KERDI-LINE-V 50 G2
  • Schlüter®-KERDI-LINE-D (covering support)

 
Installation with low construction height:
Schlüter®-KERDI-LINE-H, -H 50 G2 and -F are designed for horizontal drainage to a floor level. Schlüter®-KERDI-LINE-F is particularly well suited for renovation projects due to its low assembly height of just 60 mm. If drainage through a floor level is a possibility, an installation height of ≥ 24 mm can be achieved with Schlüter®-KERDI-LINE-V.


Schlüter®-KERDI-LINE-H
Horizontal drain

  1. The channel support is installed on a level substrate with the appropriate height. To offset uneven sections or for height adjustment, the channel support may also be installed and aligned over several, sufficiently spaced spots of adhesive or on a full layer of levelling screed. For wall installation, the channel body must be aligned in accordance with the thickness of the wall covering. For intermediate installation, use the supplied filling strip to create symmetrical dimension for the channel support.
    Note: To improve sound insulation in shower areas, install the insulating membrane Schlüter®-KERDI-LINE-SR and place a perimeter insulation strip along the edge area. Install the sound insulation membranes loosely on the level, solid ceiling with abutting joints. The printed side must be facing up. To avoid sound bridges, the joints can be covered with the jointing tape Schlüter®-DITRA-SOUND-KB. See the planning basis for further installation details of certified system assemblies – in accordance with noise insulation requirements of the corresponding standards and regulations.
  2. Fit the channel body into the channel support together with a custom cut drain pipe for connecting to the drainage system of the building. Perform a leak test.
  3. Next, abut the sloped tray Schlüter®-KERDI-SHOWER-L to the precisely installed Schlüter®-KERDI-LINE drainage channel at the proper height on a sufficiently weight-bearing levelling layer of screed or a bound fill, flush with the upper edge of the channel support (see product data sheet 8.8). As an alternative, you can also install a sloped screed at the correct height that is flush with the upper edge of the channel support.
  4. To integrate the Schlüter®-KERDI collar, apply the sealing adhesive Schlüter®-KERDI-COLL-L (see product data sheet 8.4) to the adjoining waterproofing assembly with a 3 x 3 mm or 4 x 4 mm notched trowel and completely embed the Schlüter®-KERDI collar in this assembly. Observe the curing times of all materials. Use Schlüter®-KERDI-COLL-L to tightly seal the wall connections with Schlüter®-KERDI-KEBA. Installation with low construction height: Schlüter®-KERDI-LINE-H is designed for horizontal drainage on the floor level. If drainage is to go through at floor level, an installation height of ≥ 22 mm can be achieved with Schlüter®-KERDI-LINE-V.

 

Schlüter®-KERDI-LINE-H 50 G2
Horizontal drain with water trap height of 50 mm

  1. To achieve the minimum assembly height of 120 mm, shorten the adapter (maximum insertion depth 90 mm) up to a minimum insertion depth of 15 mm.
  2. Reattach the adapter to the channel body and screw it firmly into place.
  3. Place the drain casing on the adapter and firmly push it in.
  4. Apply thin-set adhesive to create a level substrate in the area of the channel support. Place the channel body with the channel support on the drain body and firmly push it in. If necessary, apply spots of adhesive for height adjustment. Secure the drainbody against adapter slippage. For wall installation, the channel body must be aligned in accordance with the distance from the wall and thickness of the wall covering (see installation examples 4a and 4b).
  5. Connect and align the on-site drain pipe.
  6. Now apply the sloped screed (2%) of the shower area, over a suitable insulation layer if applicable.
  7. Apply thin-bed adhesive to the screed. A notched trowel size of 3 x 3 or 4 x 4 mm is recommended for installing Schlüter®-DITRA 25. Use size 6 x 6 mm for installing Schlüter®-DITRA-HEAT.
  8. Now adhere Schlüter®-DITRA 25 or -DITRA-HEAT, sealing joints with Schlüter®-BAND and Schlüter®-KERDI-COLL-L (see product data sheet 6.1 and 6.4).

Fire protection solution for KERDI-LINE-V 50 G2 with Schlüter®-KERDI-LINE-BS / -ZBS

The system components prevent the spread of fire to other floor levels according to approval number Z-19.17-1719. The fire protection insert (Art. no.: KL BS) is positioned in the drain body of the linear drainage set Schlüter®-KERDI-LINE-V 50 G2.

To install the fire protection insert KL BS:

  1. Position the fire protection insert KL BS.
  2. Attach the clamping ring, using the supplied lubricant.

In conjunction with the optional conduit gasket (Art. no. KD ZBS) inserted into the core hole (diameter 160 mm), see Fig. 6, the source material contained in the fire protection insert expands when a temperature of approx. 150 °C is exceeded to safely prevent the penetration of heat, fire and smoke for a fire resistance period of R120, R90, R60, R30 (depending on the ceiling).

Note: The fire protection function of the conduit gasket KD ZBS only applies in conjunction with the fire protection insert KL BS! Alternatively, the drain body can be embedded in concrete or subsequently covered with a class MG III cement mortar in the floor slab.

 

Installation at upright lateral wall

  1. Cut the Schlüter®-KERDI collar to size for the corner area.
  2. Tightly seal the Schlüter-KERDI collar with Schlüter®-KERDI-COLL. Then cut the supplied Schlüter®-KERECK internal corner to size…
  3. …and adhere it with Schlüter®-KERDI-COLL-L.

 

Installation of frame and grate

  1. Insert the frame with the spacer strip.
  2. Use the height adjustment aid to match the frame to the covering thickness – see drawing for details.
  3. Fill thin-bed adhesive underneath the frame on all sides and fully embed the covering.
  4. Remove the spacer strip and height adjustment aid after curing. Now install the grate.
     

Note: When installing a profile frame with polished finish, remove the protective foil prior to grouting. Residue of adhesive and tile adhesive should be removed immediately.

 

Installation of Schlüter®-KERDI-LINE-D frameless covering support

  1. For wall installation, remove the protective foil of the cover strip as shown, and adhere the unit facing the wall.
  2. Now place to spacers into the channel body...
  3. ...and connect it flush with the covering of the shower area. Remove any excess thin-bed adhesive and completely close any exposed areas in the adhesive bed (see note).
  4. Against wall installation, the width (W) of the covering equals the clear distance from the wall to the inside edge of the spacer less 1 mm. For intermediate installation, the width of the covering equals the inside dimension of the spacer (= 50 mm). On the front sides, the cover may be adjusted to the joint width of the overall covering or be installed as a circumferential drainage gap if applicable.
  5. Once the covering has cured, remove the spacers and apply thin-bed adhesive to the covering support.
  6. Adhere and align the covering. Leave the area of the covering support open when applying grout.
     

Note: Remove any excess thin-set mortar and completely close any open areas in the adhesive bed.

Note: The use of acetic-crosslinking silicone is not permitted on channels, frames and grates.
