What is the difference between the basic and professional model?

The basic model chimney fan has an 8-year warranty and resists up to 300 degrees.

The professional model resists up to 700 degrees (so, even in case of flue fire) and is recommended if you have a flue shorter than 3 meters. In addition, it has a 15-year warranty and sucks up 3800 m³/h instead of 2500 m³/h. It is also fully painted, even at the base.

In addition, we have the professional top-of-the-range copper model, which resists up to 700°, has a 15-year warranty and sucks 3800 m³/h. It has a stainless steel fan and has even more resistance over time. It is entirely painted externally (even at the base) and is, therefore, suitable for those who are looking for more aesthetics.

Does the chimney fan also suck up heat?

Our electric chimney fan has a 6-speed regulator, just put it at the first or second speed to facilitate the suction of smoke in a natural way, but not of heat.

In short, with the first two speeds, we are not going to alter in any way the normal operation of a chimney, which normally loses a very small amount of heat in the smoke that goes up the flue.

Gemi chimney fan sucks up the smoke that would otherwise go into the house and, therefore, would not produce any heat source for the interior.

It is clear that if the chimney fan was operated at the sixth speed (usually used for the exchange of air in rooms or to facilitate the ignition of the fire or to suck up the ash) with its 2500m³/h (basic) - 3800m³/h (pro), it would be so powerful to suck up even the heat, because it would increase firewood combustion speed and, consequently, reduce the heat partially.

Scientific research has shown that a chimney without a fan disperses more heat than a chimney with a fan, as thanks to mechanical control, the Gemi extractor fan is able to control heat loss.

On the other hand, without the use of a mechanical fan, it is not possible to control the loss of heat. As a result, we have some ups and downs in terms of suction. Studies show that a chimney without the use of a fan loses 30% more heat.

What stated above can be witnessed in the millions of satisfied customers all over the world since 1983 , the year in which the first Gemi chimney fan was created.

What size is the chimney fan?

The base of the electric smoke extractor has a standard size of 43x43 cm, the height is 43cm, without base. With the base, the total height is 60 cm. For more specific sizes, you will find all size details by clicking here:

How many years warranty does the chimney fan have?

The basic model of the chimney fan has a 8-year warranty, while the professional model and the copper one have a 15-year warranty.

I have a flue larger than 43 cm, can I still install the chimney fan?

Yes, the electric chimney fan with square base is equipped with adjustable brackets, in square or rectangular shape, with sizes ranging from a minimum of 20x20 cm to a maximum of 43x43 cm. If the outlet of the flue is more than 43x43 cm, it will be enough to place the fan on the masonry and fix it on the 4 corners with 4 Fischer screws vertically on the masonry. Here are some installations made by our customers in case of installations on flues larger than 43 cm:

How can I choose the right chimney fan according to the diameter of my round flue?

We provide adapters for round flues, from 10 cm to 43 cm maximum. To order the adapter, simply select the fan with round base and choose in the drop-down menu the size of the adapter you wish to purchase.

You have to consider the outside diameter because our flue adapter fits outside of its outlet. If the flue has an external diameter of 25 cm, you will have to select the 25 cm chimney adapter in the drop-down menu.

We will provide you with a slightly wider adapter so that it will fit perfectly.

I have a square flue with a pipe inside, which model do you advise me to buy?

If you have a square flue with a pipe of the same height as the masonry, you must first close the gap between pipe and masonry and then install the chimney fan directly on the masonry.

If the pipe is only a few cm high, you have to bring the pipe flush with the masonry.

In this situation, you have to buy the model of chimney fan with square base, also adjustable for rectangular flue.

Can I install the fan inside a chimney pot?

Yes, you can, but you have to consider the size of the chimney fan. The installation of the chimney fan can be carried out 2 ways:

removing the chimney pot hat and then installing the chimney fan

inserting the chimney fan inside the chimney pot, ordering the fan without hat (asking directly by phone to our specialized technicians calling +39 0287165556 or by e-mail at [email protected])

Where should the fan regulator be installed?

The chimney fan regulator should be connected to the 220 V power supply and can be installed in any area. It is important that it is not placed near heat sources.

Indeed, inside the fan regulator, there is a transformer that works at high temperatures.

Is it possible to run the cable through the flue?

Yes, using our special cable resistant to high temperatures. (cable covered with flexible steel sheath with silicone insulated cable inside, certified to work at very high temperatures) You can buy it directly by clicking here:

How long can I leave the chimney fan on?

There is no time limit. The chimney fan can work even all day, without any problem. It is designed to work without any problem even for consecutive days.

At what distance from the flame should the fan be placed?

The professional chimney fan can be installed at any height, even on 1 m high flues. On the other hand, the basic model of the chimney fan is recommended for flues higher than 3 meters (due to the high temperatures reached under 3 meters).

If the power is out, and the chimney fan cuts out, does it block the smoke outlet?

No, the chimney fan, when off, does not obstruct the normal smoke escape. For this reason, it is possible to start up the chimney fan even in certain situations, for example when the stove door is raised or in case of strong winds

If it rains, does water seep inside the fan?

No, the base of the chimney fan has a mount to prevent water seepage in the event of rain.

I recently purchased the chimney fan, when I turn it on at 1 speed it does not work, why?

Don't worry, your chimney fan is working regularly. The chimney fan is designed in this way to ensure the normal running-in of the internal bearings. Initially, once assembled, to turn on the chimney fan, you have to position the regulator at high speed, after a few minutes you can adjust it, bringing it to low speed.

This mode of use must be followed only for the first month, afterwards it will turn on at lower speeds.

Does the chimney fan solve the problem even in case of strong wind?

Of course, our chimney fan is very suitable in case of strong wind and can solve the problem of smoke without any doubt. Here is a video review of one of our customers:

Can it be installed on a round flue?

Yes, we provide adapters for round flues, from 10 cm to 43 cm maximum. To order the adapter, simply select the fan with round base and choose in the drop-down menu the size of the adapter you wish to purchase.

You have to consider the outside diameter because our flue adapter fits outside of its outlet. If the flue has an external diameter of 25 cm, you will have to select the 25 cm chimney adapter in the drop-down menu.

We will provide you with a slightly wider adapter so that it will fit perfectly.

How should the electrical connection from the cable coming out of the fan to the speed regulator (supplied with the fan) be made?

The electrical connection can be made in two ways: with a simple FG7 3 x 1.5 rubberized outdoor cable (to be routed outside the flue to the speed regulator) in order to extend the first meter attached to the chimney fan.

Otherwise, you can run the cable inside the flue, using our high temperature resistant cable.

Is the chimney fan noisy?

No. The chimney fan is silent at any speed. Obviously, when set to speed 6, the fan performs more than 1300 revolutions per minute, so there is a slight noise. However, to solve the issue of smoke, the fan should be used at low speeds, from speed 1 to speed 3 maximum. At these speeds, the sound pressure does not exceed 38 Db, i.e. zero noise.

How much electricity does a chimney fan use?

The consumption is really minimal, maximum 10 € per year. This is thanks to a particular study on the motor of the chimney fan, designed by Gemi Elettronica technicians, which allows a minimum absorption.

How much does the chimney fan weigh?

The weight of the chimney fan, excluding the speed regulator, is about 20 kg.
