The drain is dimensioned for small to medium volumes of water, which occur in e.g. residential buildings.

Technical information, see Technical data .

The fire protection floor drain is mounted in a drill hole or a floor opening.

The following floors are suitable for mounting:

• Concrete floors

• Reinforced concrete floors

• Cellular concrete floors

The fire protection floor drain can be used in a drill hole, or when using an empty pipe, also in a floor opening. The floor must have a fire resistance class of F30–F120 and be at least 100 mm thick. Prerequisite for this is a minimum total floor thickness, including bonded screed or floor installation panels, of 150 mm.

The drain is intended for draining waste water commonly encountered in households in constant operation, see Regulations from section: Media .

• The short-​term temperature of the wastewater may reach up to 95° C. The temperature must be considerably lower in constant operation.

• The pH value must be higher than 4 but lower than 10.

It is not permitted to introduce wastewater which would damage the product material.

Drainage capacity at an accumulation height of 10 mm above the grate: 0.7 l/s

Drainage capacity at an accumulation height of 20 mm above the grate: 0.9 l/s

The values are dependent on the total height of the drain unit.

In the case of fire, a conventional drain and a drainpipe made of plastic will melt and drip away within just a few minutes. Then there is an opening between two storeys, through which fire can spread.

The fire protection drain can resist fire for up to 120 minutes, without fire and smoke spreading through the ceiling. Because it contains a mass, which swells up at 150 °C and closes the empty areas in the lead-​in completely.

The mortar anchors hold the drain in the ceiling, even if the lower part of the casting compound breaks away.

After 4 minutes
approx. 460 °C: The plastic pipe is becoming malleable.

After 8 minutes
approx. 625 °C: The plastic pipe is melted. The mass begins to swell and to fill the entire drill hole.

After 25 minutes
approx. 800 °C: Drill hole and connection are completely closed. The water trap remains largely in tact.

The drain can be mounted in the following way:

• in a drill hole

• in a floor recess

The drain can be sealed both conventionally as well as with bonded sealing.

Depending on the type of sealing, you will require the relevant equipment set Required accessories .

The flange of the drain is intended for conventional sealing. To be able to seal the drain conventionally, you require a suitable sealing collar and a clamping ring with which the cuff is secured Required accessories .

Principle

Traditionally, sealing is made using bitumen or EPDM sealing collars. The sealing collars are laid directly onto the raw concrete or heat insulation. This process has proved itself to be particularly effective for sealing balconies, patios, floor installation panels and cellar floors. In addition, sealing collars are often used as an additional second sealing layer below the bonded seal.

The following components are required for the installation of a drain with conventional sealing:

• Drain

• Clamping ring with sealing collar for EPDM and bitumen sealing lanes

Information for processing

The sealing collar is coated with EPDM on the one side and with bitumen on the other side

Place the sealing collar on the drain and fasten it with the flange. It depends on the sealing collar used which material layer of the sealing collar is placed facing up. You can find more information in the mounting instructions of the sealing flange.

To protect against moisture penetration, apply sealing foils, which are to be processed in liquid state, directly below the tiles on screed and walls. The determination of the stress class and the underground as well as the selection of the suitable bonded sealing must be carried out in compliance with the valid standards and regulations, see: Regulations from section: Sealing .

Bonded sealing can be carried out with the help of a suitable stacking element. You have the possibility to double seal, using conventional and bonded sealing or only using bonded sealing.

Careful planning is required for professional sealing. In addition, depending on the individual dampness wear class and the type of foundation, a suitable thin bed bonded sealing with a building regulations certificate of suitability must be chosen.

Furthermore, the following factors should be taken into account:

• The drain or shower channel must be equipped with a special flange, which has an adhesive surface and a width of at least 50 mm.

• For bridging the material change from drain to screed, either a suitable sealing collar or sealing tape designed for overlapping with the thin bed bonded sealing over a width of at least 50 mm must be used.

• The screed must be laid at a minimum incline of 1–2%.

• The installation must be carried out properly in acc. with the mounting instructions and the manufacturer's information.

In connection with suitable drains, only approved bonded sealings with proof of practicability in keeping with building law may be used. See Regulations from section: Sealing .

Information regarding the procedure can be found in the instructions for use of the corresponding product.

Before assembly:

• Check if the drainage capacity of the drain is sufficient for the arising water volume Drainage capacity .

• Check if the installation height of the drain corresponds with the planned floor construction.

• Ensure that the required connection line is installed with the necessary incline to the planned installation location.

• If necessary, supply the required accessories Required accessories .

• For assembly in floor openings, supply empty pipe ⌀ 160 mm made of plastic.

During assembly:

• Observe installation dimensions.

• Decide whether or not a backflow seal is required in the insertion part of the top.

The fire protection floor drain can be employed in floors at least 100 mm thick through drill holes, if the total floor thickness including bonding screed or floor installation panels is at least 150 mm.

Thinner floor thicknesses can be increased to a thickness of 150 mm by adding mortar strengthened with non-​combustible floor installation panel (e. g. made of calcium silicate).

• Mounting is allowed on or under the floor. Fastening must be carried out using end-​to-​end threaded rods ≥ M8.

• If floor installation panels or concrete bases are to be used to reach the required fire resistance class, they must be at least 100 mm around the drill hole and laid at least 30 mm thick.

• For drill hole:
  Drill with drill bit ∅ 150–162 mmand ∅ 300 mm

• if necessary, stacking element for bonded sealing model 4925

• For floor openings:
  control panel or similar for closing the floor opening from below

• Empty pipe made of plastic, d 160

• Mortar (MG II, IIa or III)

The model can be installed in a ceiling recess or a drill hole.

The connection to the waste water system must be completed before the drain can be installed in the floor construction. Proceed as follows:

Requirements:

• A pipe to the planned drainage position is already in place for the connection to the waste water system.

• The drain pipe has an internal sealing lip.

Requirements:

• The drain is connected.

Requirements:

• A suitable sealing collar and a clamping ring are available.

• The flange is free of heavy soil.

• The complete surface of the flange is lined with material and undamaged.

Requirements:

• The flange is free of heavy soil.

• The complete surface of the flange is lined with material and undamaged.

The top with the grate must be mounted to finish off the mounting of the drain. Proceed as follows:

Normal soap or a mild cleaning agent can be used for regular maintenance and prevention of lime scale on the grate and frame. Use no scouring agent or abrasive objects.

Strong stains, even around the drain unit and the odour trap, can be removed using typical household cleaner. Rinse the detergent very thoroughly with clear water after the prescribed dwell time. There should be no residue on the components.

Use a mild cleaning agent and a washing-​up brush for cleaning.
