Frequently asked questions

  • Tips on choosing a cooker hood
    • How do I choose the correct cooker hood?
    • How wide should my cooker hood be?
      • Cooking vapours do not rise straight up but fan out over an angle of between 10 and 15 degrees. Choose a wider model so that cooking fumes are extracted effectively. 

        For a good result the cooker hood must be at least the full width of the hob. The maximum height of your cooker hood also plays a role.

    • What are the elements on the energy label for cooker hoods
      • Since 1 January 2015 cooker hoods have an energy label, with the exception of recirculation cooker hoods and cooker hoods without a motor. Novy adds extra criteria, which are even more important when choosing the right kitchen ventilation solution.


        Novy introduces EcoSmart: a series of models that use energy even more efficiently.

        As a specialist, Novy supports the trend towards appliances that use less energy. As a manufacturer we have pushed back the boundaries to achieve this, without sacrificing the basic requirements for a cooker hood: it must remove all odours and cooking fumes effectively and quietly. 

        With the EcoSmart label Novy has introduced a wide range of products that use up to 85% less energy. With an energy-saving motor which is also extra quiet and LED lighting, the level of energy consumption when the cooker hood is in operation has fallen drastically. All products with an EcoSmart label score A or A+ for energy efficiency.


    • How does peripheral extraction work?
      • The cooker hood is fitted with a peripheral extraction system. This means that extraction is concentrated at the edges of the cooker hood. This results in a faster air flow and improves the extraction output.



  • How to use cooker hoods
    • My cooker hood suddenly turns on or off
      • The remote control is pre-programmed and linked to your cooker hood. Sometimes it may happen that there is interference on your frequency from other broadcasters (for example the neighbour’s cooker hood, the garage door etc.) If this happens, you need to set the remote control to a different code. There are 10 codes available in all. View the demonstration video below or follow the instructions provided below. 

        Step-by-step instructions to change the code on the remote control

        1. Determine which code is used:

        Simultaneously press on/off and illumination button . The light on
        the remote control will flash as many times as the
        selected code.

        2. To change the code:

        • Simultaneously press the on/off and illumination buttons on the remote control (for about 3 seconds).
        • The green light on the remote control will flash
          as many times as the selected code. If you want a different
          code, repeat this step again (1x flashes
          for code 1, 2x flashes means code 2 etc. There
          are 10 codes available all.
        • Simultaneously press the extractor hood and (about 10
          The second green indicator light on the extractor hood
          flashes (release the buttons when it does so).
        • Within 10 seconds press the
          button on the remote control to set the confirmation.
    • How do I reprogram the InTouch connection between my cooker hood and hob?
      • It is important to link the remote control to the cooker hood first. The step-by-step instructions for this can be found here

        You can view the method for reprogramming the InTouch connection on the instruction video below or by following the step-by-step instructions below:


        Step-by-step instructions for reprogramming the InTouch connection:

        1. Connect the hob to the mains.
        2. Simultaneously touch the on/off and lighting buttons on the induction hob until you hear a beep. The hob will now automatically search for a code. Wait until the light on the cooker hood flashes OR you hear about eight beeps from the cooker hood.
        3. Touch the lighting button on the induction hob until you hear a beep to confirm the link between the two appliances.
        4. You can now operate your cooker hood from your Novy induction hob. 



    • What should I do if all the lights on my control panel are flashing?
      • This is the filter indicator. You can reset it by pressing the minus button for 5 seconds.

  • Maintenance of cooker hoods
    • What is the best way to clean my cooker hood?
      • A Novy cooker hood is easy to maintain if you remember the following:

        1. For regular maintenance:
        • Use a damp and dry cloth to clean surfaces.
        • Use warm water and a mild cleaning product.
        • Do not use aggressive, abrasive or chlorinated products.
        • Dry the surface afterwards with a dry cloth.
        1. Once every two to three months:
        • After step 1 we recommend a Novy stainless steel cleaner for optimum cleaning of the stainless steel cooker hood.
        • This is a soft nourishing mousse that leaves no traces of grease and is easy to use.
        • It is recommended to apply the mousse to a damp cloth and then wipe the whole surface being cleaned using a circular motion.
        • Afterwards, shine with a dry cloth. 

        If you use another stainless steel cleaner, we recommend testing it on the inside first and leaving for 24 hours. If there is no reaction, you can clean your cooker hood using this product.


    • How should I maintain my recirculation cooker hood?
      • Most Novy recirculation cooker hoods are fitted with (a) monoblock filter(s). Salsa, 828, 829, 650 and 655 are fitted with cartridges containing granules of active carbon.

        1. Once every five to six months:

        Almost all cooker hoods have a cleaning indicator, to tell you when the monoblock filter needs to be regenerated or the cartridge containing active carbon granules requires replacement. For a monoblock filter the indicator will light up after 200 cooking hours. The filter can be cleaned up to 12 times, which ensures a long service life of the filter. To regenerate the filter, place it in the oven at 120°C for 1 hour.

        2. Once every two months:
        In the case of active carbon granules the indicator lights up after 120 hours and the cartridge must be replaced.

        3. After approximately 3 years:

        After approximately 3 years (depending on the intensity of the cooking) the monoblock filter needs replacing.




    • How should I maintain my grease filter(s)?
      • The extraction capacity falls when the grease filters are saturated and do not allow as much air through.

        • It is best to clean the grease filter once a month. Cooker hoods with an electronic switch indicate that the grease filter has to be cleaned after 20 hours of cooking
        • Novy filters consist of multiple layers of metal mesh and are dishwasher safe.
        • You can also soak the filter in hot water with soda or detergent.
        • We recommend replacing the filter after about 5 years to maintain optimum results.
  • How to install cooker hoods
    • I do not have any option to create an external outlet. What are the possible solutions?
      • In some homes, a cooker hood with an external air outlet is not possible or not allowed for architectural reasons. In these cases a cooker hood with recirculation is recommended.

        A recirculation cooker hood is one that returns filtered cooking fumes back into the space. 
        Particles of grease are filtered out of the cooking fumes by the grease filter and odours are absorbed by the monoblock carbon filter.
        The cooker hood does not remove the moist air, but this can be removed from the space by means of the ventilation system. It is important to remember this.

    • How long can my outlet duct be?
      • We recommend keeping ducts as short as possible. However, the longer the outlet duct, the more resistance it creates and this has a greater impact on the efficiency of the appliance. 

        If the outlet duct is too long, you can always opt for a recirculation cooker hood or a recirculation kit for your cooker hood. This technology allows you to get rid of odours and no outlet to the outside is needed.

        We have good reasons for our saying at Novy that it all starts with a cooker hood. The proper functioning of a cooker hood is partly determined by the correct installation of the appliance and it is important that you think about this at an early stage in the construction process. Well-kept outlet ducts play a crucial role in this. In order to be able to adapt the installation to your specific situation we offer a wide range of outlet ducts and other accessories.





    • Where is the best place to locate the motor for my ceiling unit?
      • For ventilation purposes it does not matter whether the motor is installed on the cooker hood, in the duct or at the end of the duct. The location mainly depends on the installation space available.
        If the maximum installation height is 35 cm, you can keep the motor on the cooker hood. If you do not have this much installation height you can opt for the Pure'line Compact or the cubic remote motor.




    • Where is the best place to install the non-return valve?
      • You only need the non-return valve with a roof louvre; it is already incorporated in external louvres. For roof louvres you should locate the non-return valve as close as possible to the roof louvre.  

    • How can I make sure my cooker hood is working optimally?
      • One important function of the cooker hood is removing cooking fumes and odours as efficiently as possible. For optimum functioning, it is important to remember the following when installing the cooker hood:


        When using a circular outlet duct:

        • Use smooth, non-inflammable ducts with an internal diameter equal to the external diameter of the outlet connector on the cooker hood. The cooker hood requires an outlet duct measuring Ø150 mm. Extend flexible ducts to the maximum and cut them to size.
        • Do not reduce the outlet diameter. This will reduce the capacity and increase the noise level.
        • When connecting to a short outlet duct it may be preferable to fit a non-return valve in the duct to prevent draughts.
        • Use a hose clip or aluminium tape for an airtight seal.
        • When passing a duct through the outside wall, use the external louvre.


        When using a flat outlet duct:

        • Use flat ducts with rounded corners and air guides in the corners. These ducts are available from Novy.



        • Keep the duct as short as possible with as few corners as possible along its route to the outlet.
        • Avoid sharp corners. Ensure corners are rounded for good air movement.
        • When passing a duct through an outside wall which is a cavity wall, make sure the outlet duct completely crosses the cavity and protrudes slightly outside.
        • When passing an outlet through the roof, use a double-walled roof outlet with an adequate capacity.
        • Never connect to a smoke flue.
        • Ensure adequate ventilation. Fresh air can be allowed in by opening a window or external door slightly or by fitting a ventilation louvre.

        Incorrect installation can result in poor extraction, more noise, condensation and other undesirable effects.

    • Do I need ventilation in my room?
      • Insufficient ventilationresults in a loss of efficiency. A cooker hood with an external outlet will only work optimally if the air that is vented externally is replaced by fresh air (via a louvre in the window, an open door or window, or from another room).

  • Hobs
    • Do you need special pots and pans for induction?
      • To cook on an induction hob you need pots and pans with a magnetic base. When these are in contact with the hob, a magnetic field is created which generates heat. Only the pot or pan heats up, while the rest of the zone remains cold.

        If you want to know whether your pots and pans will work with induction, you can test this by holding a magnet against the base. If it sticks, your saucepan or frying pan is suitable for induction.

        Types of pots and pans:

        Pots and pans that are suitable: steel, enamelled steel, cast iron, stainless steel with magnetic base, aluminium with magnetic base

        Pots and pans that are not suitable: aluminium and stainless steel without a magnetic base, copper, brass, ceramic and porcelain

        A few tips:

        • Pots or pans that have already been used on other heat sources should be tested to ensure that the base is smooth.
        • Pots or pans that are rough or have already been damaged may damage the glass
        • Pots or pans must have a completely smooth base
        • Some pots and pans buzz when they are placed on an induction cooking zone. That does not mean the appliance is faulty, and it does not affect their functioning at all.
    • What is the best way to clean my hob?
      • The following method should be used for cleaning toughened glass:

        • Remove caked-on residues.
        • Clean the glass with water and detergent and dry carefully.
        • Use a non-abrasive sponge or cloth if the surface is very dirty.
        • If residues really cannot be removed, you can remove them with a glass scraper. 
        • Finally, you can use a glass cleaner to give the hob a glossy shine.
    • My induction hob makes a noise when cooking. Is this normal?
      • Noises can certainly occur when cooking on induction hobs. This is because the metal components in the base of the pot consist of multiple layers and vibrate. This usually occurs when using lower quality pots with glued bases. It differs from one pan to another and often reduces after cooking for a few minutes.

        Some noises are specific to the technology, while others may be caused by the pans. Here is a summary:

        Induction-related noises

        Induction technology is based on the properties of certain metals when they are exposed to electromagnetic influences. As a result so-called eddy currents occur, which make the molecules vibrate. These vibrations are converted into heat. As a result, quiet sounds are made depending on the material that is used. The sound may depend on the type of base on your pan.


        Humming sound like a transformer. This happens when you are cooking on a higher heat setting, and it is caused by the amount of energy being conveyed from the hob to the utensils. The sound will disappear or be quieter if you adjust the hob to a lower temperature. 

        Crackling sound 

        This sound occurs if the utensils are made from multiple layers of metal. The sound is caused by vibrations in the surfaces of the different layers of material that are in contact. This sound is caused by the cooking utensils and depends on their quality and the type of food being prepared. 

        Whistling sound 

        These sounds usually occur in cooking utensils made from multiple layers of material, and when two adjacent hobs are being used simultaneously on the maximum setting. The whistling sound will disappear or become quieter if you adjust the hob to a lower temperature. 

        Ventilator noise 

        To ensure that the electronics work correctly, the temperature must not rise too high. The hob is therefore fitted with a ventilator, which works on different settings depending on the temperature. After the hob has been switched off, the ventilator continues to operate if the temperature is still too high.














    • How to determine the dimensions of your pots and pans for induction
        • The cooking zones automatically adjust to the diameter of the pan to some extent.  
        • The base of the specific pot or pan must, however, have a minimum diameter (+/- 60%) in relation to the diameter of the chosen cooking zone. 
        • We recommend placing the pot or pan right in the middle of the cooking zone to get the best output from your hob. 
        • Ratio of pan diameter to element diameter
























        The ferromagnetic bottom is too far from the element:

        • Ferromagnetism= this refers to substances such as iron, nickel and other substances that can be very strongly magnetised by quite weak magnetic forces
        • This can reduce efficiency.
        • The response time may be less good.
        1.  Poor quality pots or pans:
        • Water boils poorly on one side.
        • The other side stays cold.
        • This leads to poor cooking results.
        1. Bottom of the saucepan is hollow or has a deep logo stamp:
        • Overheating occurs in areas that do come into contact with the glass.
        • Poor cooking results.
        • The temperature probe measures the wrong values.
        • The safety maximum of 240°C is not reached in the middle of the pot or pan (or only after a long time).
        • So the base can reach temperatures of 500°C and damage the electronics.















    • Other problems that occur with pots and pans for induction
        1. The ferromagnetic base is too far from the element:
        • Ferromagnetism= this refers to substances such as iron, nickel and others that can be very strongly magnetised by quite weak magnetic forces
        • This can reduce efficiency.
        • The response time may also not be as good.


        1.  Poor quality pots or pans:
        • Water does not boil well on one side.
        • The other side stays cold.
        • Gives poor cooking results.
