FAQ

General questions about BORA

Steam and vapours rise at a maximum speed of one metre per second. The BORA cooktop extracts with cross flow suction that is higher than the speed at which cooking vapours rise. In this way, the cooking vapours and odours are effectively extracted on the cooktop.

At BORA you can choose between the modular systems BORA Professional and BORA Classic, and the compact systems BORA X Pure, BORA Pure, BORA Basic and BORA GP4 (only available from nobilia retailers). Our product finder will help you, and your BORA retailer will be happy to advise you so that you can find the system that best suits your cooking style and design requirements.
The modular systems give you optimum design freedom and flexibility when choosing your cooktops (induction, surface induction, gas, Tepan). BORA Professional boasts extra-deep cooktops and operation via a control knob (like in professional kitchens). All functions are easily, conveniently and intuitively activated by turning the knob and tapping the central touch-operated surface. BORA Classic is operated on the cooktop itself using the intuitive sControl+ touch controls.
The compact systems also combine a cooktop with four cooking zones and an effective extractor: BORA X Pure: surface induction; BORA Pure: induction, BORA Basic: Hyper. The compact appliances have intuitive touch controls on the cooktop. With standard dimensions and the combined design, they can be installed quickly and easily.

Depending on the system, up to 300 ml of liquid can collect in the cooktop extractor and be washed away without issue. If more liquid than this gets into the cooktop extractor, this cannot damage the electronics as the air flow does not pass through the electronics.
With BORA X Pure, BORA Pure and BORA Basic models, larger volumes of up to 3 litres of liquid can also be caught. The housing base can be removed for simple cleaning.

Objects that fall into the cooktop extractor land in the collection dish and can be removed easily. The stainless steel grease filter prevents objects from being drawn into the airflow.

All removable parts such as the grease filter, drip tray, air inlet nozzle/cover can be removed easily by hand and cleaned in the dishwasher.

In contrast to traditional extractor hoods with a high noise level at head height, BORA is quieter when cooking than normal noises that occur during roasting. The volume level largely depends on the BORA system used, the individual installation situation and the room conditions.

Cooking vapour, evaporated grease and the odours that go with them are completely extracted where they arise – directly on the cooktop. The cook stands in fresh air, while their clothes and hair remain unaffected by cooking vapours.

Cooking vapour is easily absorbed even from a pot with a height of 20 cm. We recommend that for pots with a height of approx. 21 cm and over, you position the pot lid diagonally to conduct the vapours in the direction of the extractor.

The normal manufacturer's warranty is 2 years. In addition to this, we offer you the chance to extend your warranty.

Yes, BORA offers an extended warranty for any BORA cooktop extractor system. Extending the warranty by 1 year to 3 years is free of charge.The warranty can be registered at any time within the two-year manufacturer’s warranty period. The 10-year warranty can be purchased at a price of €249.90 (including statutory VAT). Being able to obtain a 10-year warranty depends on the place where the BORA system is installed. You will find the registration code on the sticker on the cooktop extractor and on a supplementary sheet. You can enter the registration code or alternatively the FD number (product number) at bora.com/registration.

Go to www.bora.com/registration. To register your system, you need the registration code or the FD number. This can be found on your appliance’s sticker, nameplate or product insert. 

The warranty can be extended within the two-year manufacturer's warranty period. The manufacturer's warranty comes into effect when your BORA system is installed. Specify the installation date when registering your system.

Yes, the warranty extension applies to all BORA product lines that are registered within two years of installation.

No, you only need to register one of the cooktop extractors. The warranty then covers the whole system  (cooktop extractor/cooktops through to the pipes and wall sleeve. For further details, please see the warranty conditions).

You can find the warranty conditions under the following link: https://www.mybora.com/warranty2plus1

Start the warranty registration for your BORA system as normal by entering the registration code (found in your system’s product documents). You can then enter the voucher code during the payment stage. Click ‘Buy and activate’ to complete the process and activate the warranty.

Either from your local BORA retail partner in store or in our online shop.

No, BORA products are only intended for use in private households.

Thanks to the central operating panel and optimally placed cooking zones, the cooktop provides enough room for up to four 24 cm (diameter) pots. Link.

Yes – in the case of BORA Classic and BORA Basic, the air inlet nozzle simply needs to be replaced to do this. In the case of BORA Professional, both the control knobs and the cover flap and cover frame must be replaced. To do this, please contact your local BORA retail partner.

Questions about humidity

Relative humidity gives the saturation level of the air at the current temperature. Warm air can take up more water, cold air can take up less water. I.e. cold air is saturated more quickly. For a comfortable heat, the relative humidity lies between 25 and 60% at a room temperature of 20 to 25 degrees Celsius.

During normal cooking, say cooking for approx. 30 minutes e.g. vegetables, fish or meat, the increase in relative humidity in the exhaust air is barely measurable. If water is boiled vigorously for 30 minutes, the relative humidity increases by approx. 10%.

Watch the video "How humidity develops during cooking” here.

In compliance with current building standards and the German Energy Saving Ordinance (EnEV and DIN 4108), mould formation is excluded when using BORA air circulation or exhaust systems in old and new buildings, and in a normal indoor climate. Wood and kitchen components, as well as other components, are not damaged.

In general: Observe the general instructions in BORA’s assembly documentation for air circulation and exhaust operation!

Questions about the exhaust solution

In the case of BORA Professional and BORA Classic, using different fan modules and the BORA Ecotube duct system, exhaust ducting measuring at least 16 metres can be realised, or 6 metres in the case of X Pure, Pure and Basic. Bends reduce the potential duct length. In the case of BORA Basic with surface induction BFIA, exhaust ducting stretching 10 metres can be fitted if using the additional duct fan ULIE.
For BORA X Pure, BORA Pure and BORA Basic, the exhaust channel should not exceed the maximum length of 6 metres. It generally applies that bends can be replaced in certain circumstances and so the duct length can be shortened.  Your local BORA partner is available to help you with your customised planning requirements.

Yes, each of the cooktop extractors needs separate exhaust ducting with separate wall sleeves or, optionally, its own recirculation unit.

 

Ecotube is BORA’s own customised exhaust air duct system, which is easy to install and perfectly designed for BORA cooktop extractor systems to ensure optimum air flow with a 100% functional guarantee.

Questions about air circulation

Yes, all BORA cooktop extraction systems can be planned both as air circulation and as exhaust air variants.

The recirculation filter unit ULBF must be replaced every 1.5 years (300 operating hours), recirculation unit UUE1 once a year and recirculation unit ULB3X every three years or every 600 operating hours. The integrated filter (PUAKF) on the BORA X Pure and BORA Pure cooktop extractor systems and on the BORA Basic (BAKFS) and BORA GP4 (BAKFS) should also be replaced on a yearly basis or every 150 operating hours. The integrated filter indicator notifies you when this period has passed.
This link will take you to mybora shop, where you can easily order your replacement filter. You can find more information on changing the filter at https://www.bora.com/int/en/service/filter-replacement/

The recirculation unit ULBF is the follow-up model for ULB1 with Ecotube connection. For all Naber duct connections, ULBF is supplied with an adapter.

The purified air is fed into the plinth area from where it is released back into the room through a return flow aperture measuring at least 500 cm² per recirculation unit. Gas cooktops require a return flow aperture measuring at least 1000 cm² per recirculation unit.

In a normal indoor climate and with proper installation, there is no risk of condensation or mould. With regard to this, please take note of the operating instructions.

To guarantee optimal performance from the odour-neutralising activated charcoal filter, we always recommend the automatic after-run function. This runs for 20 minutes and adjusts itself automatically as soon as the ventilation is turned off. Basically, you should ensure that there is sufficient ventilation (e.g. an open window) when cooking in recirculation mode.

The filter change depends on the chosen BORA product line (and the recirculation model respectively) and the recirculation filter used. For details, please refer to the operating instructions. You can find these in digital format here. Info about changing the filter can be found here.

Questions about cooktops and accessories

Yes, a large range of modular cooktops is available from the BORA Professional and BORA Classic product series. Here you can choose between induction cooktops and HiLight or Hyper cooktops – the classic models with radiant heating elements. The gas cooktop and Tepan stainless steel grill complete the assortments. BORA Basic cooktops are available as Hyper and surface induction models. BORA Pure and BORA GP4 are induction cooktops, BORA X Pure is a surface induction cooktop. BORA Basic is available in Hyper and surface induction models (while stocks last). You can find further information on our product range here.

BORA cooktop extractors are only available in combination with BORA cooktops and vice-versa.

In the case of BORA Classic, X Pure, Pure and Basic, this is not possible. In the case of BORA Professional, the cooktops can be ordered and operated independently from the cooktop extractor.

The cooktops are developed together with the extractors. Alongside optimum functionality, their dimensions make optimum installation conditions possible (cooktop extractor + cooktops).

All BORA product lines can be installed flush and surface-mounted. For Classic, there is also the option of installing the standard combination with 2 cooktops virtually flush on worktops made of any kind of material with the help of the BORA Classic CER frame.

No, the product lines cannot be combined with each other.

The BORA Basic brushed stainless steel cooktop frame is an accessory for surface mounting.They are available in two sizes: BKR830 for BORA Basic BFIA/BFIU and X Pure with a width of 830 mm, and BKR760 for the 760 mm wide BORA Basic cooktops BHA/BHU, for BORA Pure and BORA GP4.

The trim, made from 100% stainless steel, provides protection for the sides of all BORA cooktops with a depth of 515 mm. The trim can be retrofitted in the case of surface-mounted systems. The All Black model comes with our tried-and-tested diamond-like carbon coating.

The standard delivery includes the black PUED air inlet nozzle. The colour versions greige (PUEDG), blue (PUEDB), jade green (PUEDJ), red (PUEDR), orange (PUEDO) can be ordered separately as accessories.

No, despite having the same outer diameter of 173 mm, the removal technology (tilt mechanism) prevents the X Pure air inlet nozzle from being inserted flush into the BORA Pure. The same applies vice versa, i.e. the colourful Pure air inlet nozzles do not fit the X Pure.

Questions about planning and assembly

Yes, but you may need to shorten the depth of the drawers, depending on the installation.

Basically, this is not recommended, as the BORA system will not be accessible to service engineers when the appliance needs to be serviced. In addition, the cooktops could overheat. 

This varies depending on the selected product, the position and the number of cooktops and cooktop extractors. With a standard arrangement involving two cooktops and one cooktop extractor, you need a floor unit with a width of at least 900 mm for the BORA Professional and BORA Classic ranges. With three cooktops and two cooktop extractors, a width of 1,400 mm is required. This can be created by installing a single front cover across multiple floor units arranged in any format.
With BORA Basic BFIA/BFIU and BORA X Pure, the floor unit must have a width of 900 mm. With BORA Basic BHA/BHU and BORA Pure, the floor unit must have a width of 800 mm.

From the front edge of the front cover, a depth of at least 600 mm must be available (plus worktop overhang, if present) for the installation of BORA Classic, BORA X Pure, BORA Pure and BORA Basic.

The installation depth of BORA Professional varies according to the type of installation. We recommend a minimum depth of 700 mm (plus worktop overhang, if present).

For all four BORA cooktop extractor systems, we need a worktop with a thickness of between 10 and 40 mm, including base. The base needs to be notched accordingly for thicker worktops.
