Arietta Dekor Glass Island Range Hood - Stainless Steel Island Range Hood
If I have trouble during installation, whom can I contact?

The Elica/Arietta instruction manuals contain all the information you need for proper installation. If your instruction manual is not present, you can download one for your specific product by navigating to that product’s page on this website.

If you want to find a specialized installer or purchase the extended Arietta warranty, please fill out the form in the contact section.

It seems like my hood is vibrating. How can I check?

It’s essential to understand whether the vibration is mechanical or electronic.

In most cases, the cause is an installation error. If checking the installation doesn’t solve the problem, you’ll want to contact the support center by phone or email in your area for additional analysis.

I need a measurement that’s not shown in the catalog.

If you can’t find a measurement in the products section of the Arietta website,  please fill out the form in the contact section located here.

A light is flashing. Do I need to call support?

Most Arietta products feature a system that alerts users when the filters are saturated (40 hours of use for grease filters and 160 hours of service for carbon filters).

When the alert is on (the LED is flashing), the filters need to be cleaned and reset as described in the instruction manual. If you clean the filters but don’t reset the alert, the button panel will continue to flash the LED.

When this happens, check the instruction booklet to perform the reset.

Why does my hood produce drops that fall onto the cooking surface?

If the cooking surface is electric or induction, it’s normal for condensation to drip. This phenomenon does not generally occur on gas cooking surfaces because the gas heats the pan and the surrounding air.

Consequently, the hood heats up as well, and as the steam rises and encounters a hot surface, it evaporates.

Induction surfaces heat the pan but not the surrounding air, and consequently, when the steam rises and meets a cold surface, the moisture turns to droplets that fall back onto the cooking surface.

I’ve had a hood for years and can’t find a replacement part.

We recommend filling out the form in the contact section located here.  Include in your message the information shown on the silver label inside the product.

If the label has deteriorated or is illegible, you can send a photo of the product describing the spare parts you need to

I need a reducer or one-way no-return valve.

We only recommend the one-way no-return valve for ducted versions vented into a shared chimney to prevent odors from other homes from flowing back through the hood.

If possible, the hood should always have dedicated ducting and not be vented into a shared chimney. If you would like to request a reducer or a one-way no-return valve, you can contact the support center in your area.

What should I do if my hood has no suction?

First, determine whether your hood is ducted or recirculating.

If it is recirculating, the hood scrubs out the odors produced by cooking, while most of the vapors are returned to the room.

If the hood is ducted, odors and vapors are expelled outside your home.

The following conditions are required for the hood to function correctly:

  • The diameter of the outlet duct should never neck down more than 20% from the original diameter.
  • The ducts must have the fewest possible curves.
  • Avoid reduced-length ducting if possible.
  • If the conduit terminates in the wall and not the roof, a mesh screen must be positioned over its outlet.
  • Avoid using a decorative grill with fixed slats, which can reduce performance by up to 50%.
How are suction tests performed?

Section tests are done by checking the outflow of air in the upper part of the hood by simply removing the tube, leaving the vent open, and turning on the hood.

If air comes out, the hood works, so a decline in performance has to be found by investigating any problems with the installation.

What ducting should I use for the best performance?

The choice of ducting depends on the configuration required in your kitchen.

We recommend:

  • Flexible ducting for direct venting.
  • Rigid ducting in cases of a decrease in cross-section involving one or more curves. In this case, the ducting will also decrease the noise generally created by extendable corrugated tubing.
I have an 80-mm hole. Can I still neck down the outlet tube?

The diameter of the outlet duct should never neck down more than 20% of the original diameter.

For example, if the vent is 150 mm, the cross-section should not be reduced beyond a maximum of 120 mm. If starting from 120 mm, you can reduce down to 100 mm; if starting from 100 mm, you can reduce down to 80 mm.

A reduction of more than 20% significantly decreases performance and increases noise.

Do you recommend using a recirculating or ducted range hood?

If it is recirculating, the hood scrubs out the odors produced by cooking, while most of the vapors are returned to the room.

If the hood is ducted, odors and vapors are expelled outside your home.

Where possible, a ducted hood is always the better-performing option and is preferable.

What should I do if my aluminum filters are discolored after going through the dishwasher?

The instruction manual will indicate whether or not your hood filter is dishwasher safe.

The type of washing can dull the filter without altering its filtering capacities.

I have purchased an island hood. Can I vent the exhaust laterally?

In this case, in part to achieve an attractive look, you will need to modify your installation by creating a false ceiling that will allow for partial travel of the upper flue.

What should I do if I can’t install the charcoal filter?

The Arietta range hood instruction manual provides images that show you how to install the filter correctly.

How can I clean the hood to achieve the best results?

The hood must be cleaned using neutral products (pH 7) that are neither alkaline nor acidic.  You must check that the product does not contain harmful components such as sodium carbonate, acids, ammonia, or chlorine.

If your hood is steel, you must pay careful attention to the cleaning product you purchase since the substances listed above can deteriorate the steel, leading to stains or spots of rust.

This is why Elica/Arietta has created a special cleaning line: E-Clean. The E-Clean range includes special cleaning products for steel and glass hoods and a multipurpose cleaning cloth. All products in the E-Clean line are available for purchase on

I am using a ducted hood. Do I need to arrange a ventilation hole in the upper part of the room?

The ventilation hole is not required for the ducted version since the hood’s channeling provides the hole’s service required by the standard.

If the hood features a one-way no-return valve, then the hole is necessary because the standard requires that there always be an external vent to prevent the accumulation of harmful dioxides.

Will my hood be damaged if I don’t change the carbon filter regularly?

The carbon filter guarantees regular cleaning of dirty air when cooking in the kitchen.

The carbon filter has a certain lifecycle: with time, the grease particles that accumulate on it will obstruct the passage of air, leading to ineffective filtration and will increase motor noise.

We recommend you change the carbon filter every three months.

How can I identify which hood I have in my home?

The model of each kitchen hood is shown on the silver label inside the product.

It will have a 12-digit code starting with  “208”.

This code is crucial for identifying the model of the technical filter and other accessories and requesting technical service on the product.

What should I do if the specification label is no longer legible?

If the label has deteriorated or is illegible, you can send a photo of the product describing the spare parts you need to

Do all models come with a drilling template?

Not all Arietta range hood models are sold with a drilling template.

If you want to know whether a particular model provides one, please write to, indicating the 12-digit code starting with “208” on the silver label inside the product.

I have purchased a hood that hasn’t arrived yet and would like to get started on the fastening holes. Can I request a drilling template?

If your model includes a drilling template, it’s already included in the hood packaging.

If a particular model does not have a template, we recommend contacting to inquire if a drilling template is available for the product you purchased. 

I have lost my instruction booklet. How can I get a new one?

The booklets for our hoods are available in PDF format on the specific product pages on this website.
