How to properly install a flow hood over a gas stove?

The hood is one of the most important elements of kitchen appliances. The comfort of being in the kitchen, the safety of the wall covering, ceilings and furniture, the aesthetic appearance of the kitchen depend on its choice and placement - a modern hood has long been an important element of decor.

The exhaust system is especially relevant in a kitchen with gas stoves - unlike other types of hobs, gas heats up the air to a great height, releases harmful decay products during its combustion, and burns out oxygen.

With intensive cooking, air purification is a must in the room

When deciding how to install a hood over a gas stove, you should be especially careful about the type of exhaust system, not every design provides optimal operation in rooms with gas.

Primary requirements

Functionality

The flow hood will remove the polluted air, the circular hood will purify the polluted air with filters and return it to the room

All hoods are divided into two large groups: circular and flow, in the first, the air is passed through filters and returned back. At the same time, high humidity will remain in the room, many harmful decomposition products during gas combustion, air with a low oxygen content - the norms for the content of harmful substances can be exceeded.

When using flow types, polluted air is removed outside the kitchen and replaced with fresh air - this type of exhaust system for gas hobs is preferable.

Aesthetics

The exhaust system should optimally fit into the interior without disturbing the appearance of the kitchen. To do this, hoods are built into furniture (cabinets above the stove), the color of the work surface, case, or design is selected to match the style of the kitchen.

A lot of people forget about this, installing especially popular lately modern high-tech inclined models made of glass and metal, with black glossy surfaces, in any kitchen, often reminiscent of a classic or Provence style with light wood-like furniture.

Efficiency

The exhaust system in the kitchen should eliminate as much as possible all the negative consequences of cooking food: extraneous odors, water vapor with tiny droplets of fat, soot and soot particles in the air, high humidity. The hood for the gas stove must be correctly installed above the hob, have the appropriate power and performance.

Classification

By design, all existing hoods can be divided into several groups.

flat

Flat options have a minimalist design and will not stand out from the rest of the kitchen elements.

A very common type, a flat worktop is parallel to the hob. They take up little space, mainly the design is used in circular forms.

Dome

Such models capture more air when cooking.

One of the most common designs, in appearance they resemble a dome, lowered over the hob along a square tube in the upper part. In almost all designs, this pipe is part of the duct, and dome hoods are built into a flow-through exhaust system - such designs are very rarely used in circular types.

Retractable

Retractable models are practical, but have a short length, so they capture less air during operation.

To increase the service area, the working surface of the hoods is often increased by a retractable module. Typically, such models are built into the lower part of a wall-mounted kitchen cabinet, in which an air duct can be hidden or in the case of circular ones - there is space for placing kitchen accessories. Retractable - a very convenient design when installing an exhaust system in small kitchens.

corner

Corner models are not so widely used, so the choice of design and functionality may differ from the standard options.

Placed in the corner of the kitchen, designed for a gas stove, turned at an angle of 45 degrees to the main wall. The working surface of the hood has the shape of a square with a truncated corner.

Island

Island options become exclusively in islands in the kitchen

Designed for placement in large kitchens, if the hob is located in the center of the room. Typically, the hood is lowered over the hob on a square duct.

Inclined

Inclined models have a stylish appearance and standard functionality.

A modern solution for kitchen exhaust systems, in which the working panel is located at an angle to the hob. This allows an inclined model, with the same area as a flat horizontal one, to occupy less free space in the kitchen. The design looks most aesthetically pleasing in modern high-tech kitchens.

Desktop

More recently, a new type of hoods has appeared, saving space for wall cabinets or shelves

The device is mounted in the table next to the hob. During operation, its suction working panel extends vertically upwards and air is pumped out.

Hoods are classified according to the installation method as follows:

• Suspended. It is fixed directly above the stove with cables or on the air duct.
• Embedded. Are established in kitchen furniture from below hanging lockers.
• Wall. Attached to the wall above the hob.

Installation height

Installation height depends on the average height of a person in the family

The main parameter during installation is the distance between the hood and the gas stove, it should not be less than 750 mm. and not more than 900 mm.

This distance is selected taking into account the ergonomic indicators of the hostess, it depends on the power of the hood - more powerful structures can be placed higher. Also, the installation height of the hood above the gas stove in many cases directly depends on the manufacturer's recommendations, which must be observed in the first place (these requirements are described in the instructions for the device).

Size

The second main parameter, the width should not be greater than the width of the hob. If structurally it rises to a height higher than recommended, its overall dimensions or suction power must be increased.

When deciding how to properly install the hood over a gas stove in the case of using an inclined model, they usually focus on the lower edge of the air intake - the minimum distance to the stove should be 550 mm.

Another important parameter of the hood is its depth, usually this parameter corresponds to the dimensions of the hob and is typical for its width.

Installation of exhaust systems

Installation may vary depending on the type of systems

Installing a kitchen hood with your own hands is quite simple if you follow the instructions and work procedure. Often the manufacturer produces kitchen hoods that combine two modes of operation - circular and flow.

Installation of a circular hood

Using the circular mode in kitchens with a gas hob is not a very good solution. An autonomous circular hood over a gas stove will not be able to provide the necessary comfort in the kitchen, its carbon filters, unlike electric stoves, will be clogged with gas combustion products faster, which will lead to additional economic costs.

Installing a circular cooker hood usually does not cause big problems: it can be attached directly to a straight wall or in a corner, built into furniture, lowered over the hob through a pipe or on cables. The sequence of work when installing it on the wall is as follows:

• The connection point is preliminarily determined, if the socket next to it does not fit too well or it is located far away, the point is transferred. In this case, it may be necessary to shred the walls and install a new outlet with wiring for connection.
• Attachment points are marked in the wall at the desired height, specifying the location of the hood, holes are drilled with a puncher and dowels are driven in. It is important to control the correct installation using the building level - the working surface of the hood must be located strictly horizontally above the stove.
• The hood is screwed to the wall with screws through the mounting holes, if the gas pipe interferes, it is removed from the wall and attached to long studs with nuts. Also, between the wall and the hood, you can put a bar of the appropriate thickness and attach the hood to it or the wall with dowels with long screws through the bar.

Flow hood installation

When deciding how to hang a hood over a stove, you should be aware that a flow hood will require the installation of an air duct system to connect it to the vent of a common house shaft, or an external outlet for air in a wall, window or ceiling.

Installation of air ducts with the installation of an exhaust hood is easy to do with your own hands, if you follow a certain order of work.

Necessary tools and materials

Choice of air ducts. For the installation of flow systems in everyday life, two types of air ducts are most often used: corrugated aluminum or plastic square or round.
