Frequently asked questions

With a every cooker hood delivery there usually comes a kit of installation screws. Don’t use any other screws than the original ones, especially for the ones that will be installed to the cooker hood body. All the screws that are meant to be installed in the cooker hood body, are usually short and flat nose type, like the ones used with Savo mounting brackets or the plastic air stopper to be installed behind the cooker hood. Using wrong type of screws can damage the internal cabling of the cooker hood, leading to a risk of an electric shock. If you have any doubts about the screw suitability, please don’t hesitate to contact the Savo customer care.

It is forbidden to install the Cooker Hood above a wood burning stove. This is due to the reason that the heat coming from the stove can be so strong, that it is too much for the plastics parts or electronics.

Liesikuvun tai -tuulettimen asentaminen puuhellan tai -kaminan yläpuolelle on kielletty. Tämä siksi, että puulämmityksen tuottama lämpökuorma voi olla niin suuri, että liesikuvun muoviset osat tai elektroniikka eivät kestä sitä vahingoittumatta.

The manual is located in the package with the installation supplies. In some models, it is in the unit behind the grease filters. The manual is located on the website also in the product information attachments.

Chimney extensions are available for some models. Chimney extensions are stated in the order instructions.

The water condensation problem may be caused by the following:

• room air humidity level exceptionally high
• insufficient thermal insulation on the exit duct
• chimney too narrow, pressure condenses the humidity to the inside wall of the chimney
• insufficient use of fan after cooking
• non-return valve missing or malfunctioning
• insufficient make-up air supply
• missing rain guard on top of chimney above rooftop or another source of rain water entering the chimney
• one or more of the above

The operation of the hood and fan are affected by:

1) cleanliness of grease and carbon filters:
the user guides state or the units notify automatically the cleaning and replacement intervals of filters

2) the premises and kitchen must have sufficient supply of make-up air:
if necessary, open a ventilation window when operating the range hood

3) select an exhaust duct sufficiently large in diameter:
recommendation Ø 160mm (minimum Ø 125mm)

4) exhaust duct length and bends:
avoid unnecessary bends or use rounded exhaust duct angles

5) upon installation, verify the cleanliness of the exhaust duct

The wanted result can be taken by dividing the m3/h with 3.6. Example: Savo C-52 has capability to move air 700 m3/s. This would be about 195 l / s.

The sound levels (dB values) of cooker hoods equipped with their own fans are stated in the product brochures and the energy label, in accordance with the EU directive. The values are stated in the minimum and maximum speeds (not high-power operation mode). The values are usually between 50–65 dB. If the solution is one equipped with a powered roof ventilator, it is possible to install a silencer in the chimney, which reduces the sound emitted from the ventilator motor above.

Planning the piping of the exhaust air is important for the freshness of indoor air. The diameter of the chimney is very important, as it affects how much air can be drawn or circulated through the pipes. T-piece dividers should be avoided. The number of 90-degree angles and narrow sections should be limited. Savo’s model brochure states the recommended chimney sizes (125mm, 160mm). When using a powered roof ventilator, the diameter of the chimney of the ventilator should match the exhaust duct of the cooker hood.

The most effective ventilation is achieved when the diameter is ∅ 160mm. The minimum for the exhaust duct is ∅ 125mm.

A cooker hood is equipped with its own motor. A cooker hood is connected to the exhaust duct or equipped with an efficient carbon filter, which allows it to recirculate the air to the room.

If you have a situation, that you have a cooker hood which is electrically incompatible with the roof top fan, Savo offers additional converter kits (from AC to EC and from EC to AC) to solve the situation. Please contact the Savo’s technical support.

When selecting a cooker hood, it is first mandatory to find out whether the roof top fan or ventilation machine is of type AC or EC.  A cooker hood of EC type can’t drive a roof top fan of AC type and vice versa. In the Savo portfolio all the EC cooker hood names start with a small letter e (e.g. eGH-56).

With apartment buildings and row houses, it is typical that the HOA defines and approves the suitable hoods for the property. Prior to starting the planning work, instructions should be obtained from the property manager. Savo also has a solution where the requirements include fire prevention technology.

When selecting a range hood for an application, where an existing remote fan is already installed, it is important to ensure the hood and the remote blower are compatible. Sufficient vacuum is not established with a weak or malfunctioning old remote blower, which results in insufficient removal of odors and smoke. A compatibility table with instructions is available here.

Prior to starting the planning work, instructions should be obtained from the property manager.

The total input power of the lights (W) cannot exceed the value stated on the power source. Ensure that they are mutually compatible, 12V or 24V.
