Schluter Kerdi Line Linear Drain
Schluter-KERDI-LINE is a low profile linear shower drain specifically designed for bonded waterproofing assemblies. KERDI-LINE can be installed adjacent to walls or at intermediate locations. The floor can be sloped on a single plane to KERDI-LINE, which enables the use of large-format tiles and creates interesting design opportunities.
KERDI-LINE consists of a formed stainless steel channel body and grate assembly or covering support to which tile is applied. The channel body features a standard 2″ (50 mm) no-hub outlet and is attached to the pipe using an appropriate mechanical (e.g., flexible or no-hub) coupling. The simple connection to standard drain outlets makes KERDI-LINE suitable for new construction and renovation. KERDI-LINE is available with both center and off-set outlets. The off-set outlet is located 8″ (20.3 cm) from the edge of the channel body and provides flexibility when obstacles (e.g., floor joists) are encountered during installation. KERDILINE includes a corresponding polystyrene foam channel support to set the drain elevation to the corresponding KERDI-SHOWER-LT/-LTS shower trays. The perimeter of the channel body consists of a bonding flange laminated with a collar made of KERDI. It ensures a simple and secure connection to the bonded waterproofing assembly, both in the floor area and on adjacent walls. KERDI-LINE is available in channel lengths from 20″ to 72″ (50 cm to 180 cm) in 4″ (10 cm) increments. The bonding flange extends approximately 1″ (2.5 cm) beyond the channel on all sides.
The KERDI-LINE grate assembly consists of a stainless steel frame that can be seamlessly adjusted to the thickness of the ceramic tile or stone covering – 1/8″ to 1″ (3 mm to 25 mm) for standard grate assemblies and 1/4″ to 23/32″ (6 mm to 18 mm) for KERDI-LINE-STYLE grate assemblies – and stainless steel grates that are placed within the frame. The standard grate assembly frame features a 3/8″ (10 mm) wide reveal after installation and can be combined with one of two grate options: SOLID (A) or SQUARE (B). Each standard assembly is available in a brushed, chrome, or textured color-coated finish. The SQUARE (B) option is also available with a locking mechanism (brushed stainless steel, 3/4″ – 19 mm frame only) for applications where tamper resistance is desired or required (e.g., healthcare and education facilities, etc.). The KERDI-LINE-STYLE grate assembly frame features a minimal reveal after installation and can be combined with one of three grate options: FLORAL (E), CURVE (F), or PURE (G). Each STYLE assembly is available in a brushed finish. The TILE grate (D) consists of a frameless, tileable covering support that is placed flush with the top of the channel body and can therefore accommodate any thickness tile covering. If KERDI-LINE is placed at shower entrance, it is recommended that grate assembly A or the TILE grate is chosen and that the drainage openings span the maximum width of the entrance to limit potential overflow; secondary drainage (e.g., KERDI-DRAIN-F) may be required in the drying area.
How to Install Your Kerdi Drain
The installation instructions below represent the use of Schluter-KERDI-LINE in floor applications.
Preparation
When installing KERDI-LINE against a wall, be sure to factor in wall board thickness before cutting the hole in the substrate.
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
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 Schluter SET, Schluter ALL-SET, Schluter FAST-SET, or 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 Schluter SET, Schluter ALL-SET, Schluter FAST-SET, or 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.
