Kerdi-Line Grate Assy KLAR 19 EB 80 Solid 32"

The KERDI-LINE channel body is formed using stainless steel 304 (1.4301 = V2A) and features a bonding flange with a KERDI collar laminated on the surface. KERDI is a bonded waterproof membrane made of soft polyethylene, which is covered on both sides with a special fleece webbing to anchor the membrane in the thin-set mortar. The frame and grates are made of stainless steel 304 (1.4301 = V2A) . The channel support is made of pressure resistant, expanded polystyrene (EPS). KERDI-LINE is suitable for use in residential and commercial applications, including areas subject to foot and wheelchair traffic, such as showers and wet rooms in homes, hotels, schools, healthcare facilities, etc. The KERDI-LINE-FC is roll-formed using stainless steel 316 L (1.4404 = V4A).  Stainless steel can sustain high mechanical stresses and is particularly suitable for applications requiring resistance against chemicals and acids. However, even stainless steel is not resistant to all chemical stresses, and may be affected by hydrochloric and hydrofluoric acid or certain chloride and brine concentrations, which may be present in detergents or swimming pools. In special cases, the suitability of the selected floor drainage system must be verified based on the anticipated chemical, mechanical, and/or other stresses. Anodized aluminum retains a uniform appearance during normal use. The surface, however, is susceptible to scratching and wear and may be damaged by grout or setting material. Therefore, these materials must be removed immediately.

The installation instructions below represent the use of KERDI-LINE in floor applications.

Preparation

1. Any leveling of the floor must be done prior to the installation of the channel body. For installation adjacent to the wall, the channel body must be aligned in accordance with the thickness of the wall covering. For intermediate installation, use the supplied filling strip with peel-and-stick adhesive layer to make the channel support symmetrical.
2. KERDI-LINE can be installed in conjunction with the provided channel support as described below or set in loose mortar. KERDI-LINE is connected to the waste line with the appropriate mechanical no-hub coupling in accordance with the coupling manufacturer’s instructions.

Channel body installation

Access to plumbing from below 
When there is access to the plumbing from below and the waste line can be connected after installing KERDI-LINE, the channel body may be set without making a connection to the waste line simultaneously.

1. Apply unmodified thin-set mortar to the substrate where the drain is to be placed with a notched trowel and solidly embed the channel support in the mortar.
2. Apply unmodified thin-set mortar to the top of the channel support with a notched trowel and press the channel body firmly into the mortar, ensuring full support of the bonding flange. Check to make sure the KERDI-LINE is level.

No access to plumbing from below
When there is no access to the plumbing from below, the channel body must be set and connected to the waste line simultaneously.

1. Begin the drain installation by dry fitting the components. Measure and cut a section of pipe to connect the coupling to the odor trap below the floor, using the channel support as a spacer.
2. Apply unmodified thin-set mortar to the top of the channel support with a notched trowel and press the channel support firmly onto the underside of the channel body. Attach the mechanical coupling to the drain outlet and the cut section of the pipe per the coupling manufacturer’s instructions.
3. Apply unmodified thin-set mortar to the substrate where the drain is to be placed with a notched trowel. Prepare the cut section of pipe and odor trap with cleaner, primer and ABS or PVC cement per the solvent cement manufacturer’s instructions.
4. Solidly embed the channel support and KERDI-LINE into the mortar on the floor and connect the cut section of pipe to the odor trap. Check to make sure the KERDI-LINE is level.
5. The screed is then placed flush with the top of the bonding flange of the KERDILINE. Slope the mortar bed using the bonding flange and mortar screeds as guides.

Note: KERDI-FIX or other adhesives that are compatible with EPS foam can be used to install the channel support and channel body as an alternative to thin-set mortar.

Apply a generous bead of KERDI-FIX to the top and bottom of the channel support. The use of KERDI-FIX limits the ability to level KERDI-LINE. Note: Schluter®-Systems recommends a leak test be performed on the connection between the drain and the waste line prior to continuing with the remainder of the installation whenever possible.

Connection to waterproofing membranes

The KERDI or DITRA waterproofing membranes can be installed as soon as the mortar bed can be walked upon.

1. KERDI, DITRA or DITRA-XL is installed up to the outer edge of the KERDI-LINE bonding flange using unmodified thinset mortar. The thin-set mortar must be mixed to a fairly fluid consistency, but still able to hold a notch.
   1. KERDI: Apply unmodified thin-set mortar to the mortar bed surrounding KERDI-LINE with a 1/4" x 3/16" (6 x 5 mm) V-notched trowel or the KERDITROWEL, which features a 1/8" x 1/8" (3 x 3 mm) square-notched design. Embed KERDI in the bond coat with the flat side of the trowel to ensure full coverage and remove air pockets.
   2. DITRA: Apply unmodified thin-set mortar to the mortar bed surrounding KERDI-LINE with a 1/4" x 3/16" (6 x 5 mm) V-notched trowel or the DITRATROWEL, which features an 11/64" x 11/64" (4.5 x 4.5 mm) square-notched design. Solidly embed the matting into the bond coat using a float, screed trowel, or DITRA-ROLLER.
2. Apply unmodified thin-set mortar to the membrane surrounding KERDILINE with a 1/4" x 3/16" (6 x 5 mm) V-notched trowel or the KERDITROWEL, which features a 1/8" x 1/8" (3 x 3 mm) square-notched design. Embed the KERDI collar in the bond coat to ensure full coverage and remove air pockets.

Grate assembly

Grate A and B

1. Apply unmodified thin-set mortar to the underside of the grate frame and place it in the channel body ensuring full coverage and support of the frame. Insert the foam spacers in the grate frame to reinforce it during the remainder of the installation. Note: The tape on the grate frame does not need to be removed. It is intended to help keep setting material out of the channel body during installation.
2. Insert the plastic height adjustment spacers with threaded bolts under the tabs along the inside of the grate frame to adjust the elevation of the frame such that the surface of the frame will be flush with the surface of the tile covering. The spacers may be adjusted simply by turning the bolts by hand.
3. Apply unmodified thin-set mortar to the substrate and install the tiles, ensuring full coverage. Once the tile covering is set and grouted, remove the spacers from the grate frame and insert the grate. Note: Protect the visible surfaces of the grate frame and grate from contact with setting and grouting materials. Setting and grouting materials must be removed immediately.

KERDI-LINE-FC

1. Install KERDI-LINE channel bodies end-to- end and overlap the KERDI collars using unmodified thin-set mortar to ensure a waterproof connection. KERDI-LINE-FC is subsequently installed in conjunction with the KERDILINE grate assembly and adjacent tiles. Note: KERDI-LINE-FC may be used with tiles that are 1/4" (6 mm) thick or greater.
2. Apply a sufficient amount of thin-set mortar to the substrate and/or the back of KERDI-LINE-FC and press the profile into the mortar until its surface is flush with the adjacent tile and grate assembly.
3. Leave a space of approximately 1/16" – 1/8" (1.5 – 3 mm).
4. Fill the joints completely with grout or setting material.

Grate D Wall Installation

1. Peel protective foil off the cover strip and adhere the strip to the bonding flange adjacent to the wall(s). Position the strip along the edge of the channel. The cover strip hides and protects the KERDI surface under the tile.
2. Insert the tile spacers into the channel body. Install the surrounding tile on the adjoining walls and mortar bed up to the spacers using unmodified thin-set mortar, ensuring full coverage. Remove all excess setting material.
3. Apply tile to the top of the covering support using unmodified thin-set mortar. The tile is installed flush with the front side of the covering support to provide the drainage opening and overhanging the back side of the covering support to cover the bonding flange along the wall. Measure and cut the tile such that an approximate 1/16" (1 mm) gap is left at the wall. When the ends of the channel body are located adjacent to walls, the tile is installed overhanging the end of the plate to cover the bonding flange along the walls. Measure and cut the tile such that an approximate 1/16" (1 mm) gap is left at the walls. Note: When the mortar bed is tiled beyond the ends of the channel, the tile on the ends of the covering support can be cut to either match the grout joints of the surrounding floor covering or to provide a perimeter drainage opening.

Intermediate Installation

1. When the ends of the channel body are located adjacent to walls, peel protective foil off the cover strip and adhere the strip to the bonding flange adjacent to the walls. Position the strip along the edge of the channel. The cover strip hides and protects the KERDI surface under the tile. When the mortar bed will be tiled beyond the ends of the channel, the cover strip is not required.
2. Insert the tile spacers into the channel body. Install the surrounding tile on the adjoining walls (if applicable) and mortar bed up to the spacers using unmodified thin-set mortar, ensuring full coverage. Remove all excess setting material.
3. Apply tile to the top of the covering support using thin-set mortar. The tile is installed flush with the front and back of the covering support to provide the drainage openings. When the ends of the channel body are located adjacent to walls, the tile is installed overhanging the end of the plate to cover the bonding flange along the wall. Measure and cut the tile such that an approximate 1/16" (1 mm) gap is left at the wall. Note: When the mortar bed is tiled beyond the ends of the channel, the tile on the ends of the covering support can be cut to either match the grout joints of the surrounding floor covering or to provide perimeter drainage openings.

Note: For acid-resistant coverings, use an epoxy adhesive to set and grout the tile.

KERDI-LINE requires no special maintenance and are resistant to mold and fungi. The grate may be removed to clean the drain housing and the drain pipes. Clean the grates and profiles using common household cleaning agents. Stainless steel exposed to the environment or aggressive substances should be cleaned periodically using a mild household cleaner. Regular cleaning maintains the neat appearance of stainless steel and reduces the risk of corrosion. All cleaning agents must be free of hydrochloric and hydrofluoric acid. Stainless steel surfaces develop a sheen when treated with a chrome-polishing agent. Do not use abrasive or alkaline cleaning agents.

Note: There are multiple selections to be made for this product. Start by selecting the appropriate flange length then proceed to grate selection accordingly, keeping in mind there are two frame heights with two grate options (A or B), and a frameless option (D).
