A spacious gazebo is a great place to gather a noisy company in the summer season, and a barbecue is an integral attribute of such a structure. It is perfect for cooking meat and vegetables, but for the most hassle-free use it should provide good ventilation with a quality hood. Some summer residents prefer to buy it ready-made, but actually making such a design with your own hands is not as difficult as it might seem at first glance. Whether such a hood is really needed in the gazebo and how you can create it from improvised tools yourself - this will be discussed later.

Functions and benefits of a homemade hood

Many summer residents mistakenly believe that an exhaust hood above the barbecue is needed exclusively to remove smoke from the arbor and to comfortably find people in it.

• However, this product also performs a number of other important functions:
• controls the power of fire in the grill;
• prevents the appearance of soot;
• prevents the negative effects of wind and the attenuation of the fire;
• gives the brazier a more complete, more attractive appearance.

Did you know? According to archaeological data, the first arbors served as protection from the sun 20 thousand years ago, and they were built on the territory of Ancient Egypt. Large monumental structures of this type appeared a bit later in Ancient Greece and Rome, where they were decorated with expensive marble and granite.

With the presence of the hood, you can not worry about accidentally igniting objects in the gazebo, and there will be much less cleaning work (soot will not settle on the floor and objects located next to the barbecue). Among the other advantages of using such a device, they also highlight the increased rate of kindling of coal (provided by the presence of directional traction), so you do not have to wait too long to cook the selected dishes.

On the modern market there are a variety of models of exhaust systems for gazebos, but home-made designs have a number of advantages over them.

First of all, these are:

1. More affordable cost of construction. The average price of a finished smoke collector varies between 12–20 thousand rubles, and the creation of a construction with your own hands will cost an average of 5,000 rubles.
2. The ability to take into account the individual characteristics and wishes of the owners. Pavilions with barbecue can be called objects of personal creativity, and therefore the hood should harmoniously fit into the overall picture, taking into account the size of the hearth and design idea when designing the entire recreation area. Of course, independent work is fraught with certain difficulties, because it requires special knowledge and skills, but most often with moderate financial costs it is possible to achieve a worthy, exclusive result.

Types of smoke exhaust structures

Both purchased and home-made chimneys can be divided into types, based on their specific characteristics: material of manufacture, type and form of placement in the gazebo and the availability of additional equipment.

Based on the first criterion, metal and brick structures can be distinguished, each of which has its own advantages. In the first case, this is versatility and the possibility of combining it with a wide variety of devices, ease of installation and further maintenance, attractive appearance, and in the second case, the possibility of combining the frypot and hood, durability, greater safety of use, due to less heating of the bricks in the furnace process.

Important! Sometimes brick hoods are decorated with wooden or plastic elements, which gives them a more interesting and solid look. In the case of metal chimneys, this option is inappropriate, since without special heat-resistant gaskets flammable material can ignite.

Based on the shape and type of arrangement of the chimney, the current “wall” U-shaped structures installed near one of the walls of the arbor, or island structures located in the center or in any other part of the building, separated from the main structure, will be relevant today. You can also find corner options, on one side of which there is a barbecue itself and a chimney, and near it there is enough space to prepare products for baking.

How to make a metal hood with your own hands

Making a metal hood is a simpler task than creating a brick system, so most summer residents choose it. In order to carry out the plan and to achieve the maximum functionality of a homemade chimney, it is necessary to choose the right materials, calculate the most suitable dimensions of the structure and adhere to a clear sequence of assembly. Each of these stages always has certain features.

Necessary materials and tools

To organize a metal hood over the barbecue, most of the components can be found at home, however, like the tools used in the work.

In this case, you will need:

• sheet of metal, 3 mm thick;
• metal corners (profile), dimensions 20 × 20 × 3 mm (height / width / thickness);
• rivets, screws and heat-resistant paint (it is advisable to choose products with a maximum level of heat resistance, for example, up to + 600 ° C);
• welding device, electrodes to it and a mask.
• drill with nozzles for working with concrete;
• riveter.

Drawing creation

The metal exhaust system includes several main components, the dimensions of which depend on the parameters of the barbecue itself. For example, for standard designs with parameters 105 × 60 cm, the distance to the top of the hood should be at least 2 m, while the width of the umbrella is determined by the size of the grill. If in your case the indicated values ​​of the base differ, then it is worth adjusting the dimensions of the hood under them. This applies not only to the frame (attached directly to the barbecue), but also to the dome located on it with an internal jumper and a chimney.

Did you know? According to the ancient Chinese teaching of Feng Shui, the best place to install a gazebo on the site is the southwestern part of the territory, where according to beliefs there is a marriage and family zone. If you plant any yellow flowers next to the arbor (for example, sunflowers, yellow-orange irises), then they will bring even more positive energy, protecting from the "evil eye".

Step-by-step manufacturing

The process of manufacturing a metal hood for the barbecue consists of three main stages: the construction of the frame base, wall cladding and the installation of the upper "umbrella". Before starting work, it is advisable to wipe the prepared metal parts with a rag from the factory grease and, if necessary, go through the grinder, removing burrs and sharp edges formed when cutting metal sheets.

Frame assembly

After preparing all the elements necessary for the frame, the further process of creating a support base involves the following actions:

1. First, weld from the metal corners and profile 2 the side parts of the base of the future hood, and then weld to them even parts for attaching the rear surface of the grill base (a U-shaped connection should be obtained).
2. Gather from the corners the lower part of the dome for the future hood hood, welding 4 parts (profiles) to each other to make a frame 1 m long and 55 cm wide (suitable for the brazier 105 × 60). Weld 11-cm pieces from the same profile to the corners of the resulting part, and on top of them, install another frame, still using welding for fastening.
3. To the corners of the obtained frame parallelepiped of a rectangular shape, weld a profile for attaching the back of the barbecue dome. New angles of 63.5 cm should be located under a slight slope in relation to each other, forming a narrowing of the dome. The height from the middle of the parallelepiped to the end of the protruding part of the profile should be 51.5 cm.
4. With the same slope of the corners, weld two other supporting profiles, so that 2 trapezes are already formed on the frame.
5. Make a 31 × 31 cm square frame from the remaining corner and weld it to the upper parts of the trapezoid, thereby fastening the entire structure.
6. Attach 4 more vertical sections of the profile, 56 cm long each, to the corners of the resulting square part, and then fix them together with the second square frame 31 × 31 cm. This will result in an exhaust pipe of the ventilation system.

Having put together all the details of the frame structure, well clean all the seams with a grinder and treat the metal with heat-resistant paint.

Sheathing and installation

As soon as the metal frame is ready, it remains only to sheathe it with sheet metal.

Important! It is better to check the strength of the welds already at the first stage of design, because in the case of low-quality welding, you will have to spend much more time correcting all the errors at all points of the profile connection.

You can do this by following these steps:

1. Mark sheet metal first to cover the sides of the bottom. The length of this segment should be 214 cm (55 cm lateral parts, 100 cm rear wall and 2 cm for fastening on the front sections of the profile). The width of this sheet is selected taking into account the width of the base of the future design, that is, 11 cm.
2. Fold the edges along the marked bending lines, which is most convenient to do by fixing the metal on the edge of the workbench.
3. Beat the base of the hood with a prepared metal sheet, fixing it to the frame profile with rivets and a special tool for fixing them.
4. Before covering the domed part of the chimney, install a metal plate diagonally on the inside to provide better traction. Its dimensions for the product with the above parameters are 99 × 34 cm and 2 cm along the edges, with the help of which it is mounted in the lower part of the dome.
5. Following the example of the marking of the first sheet for sheathing the base of the hood, open the part for fixing on the central trapezoidal section, that is, the dome. These should be 4 separate parts, with which you need to close all the free space between the profiles. The sheets are fastened using the same rivets and the installation tool.
6. Lastly, sheathe the pipe of the exhaust hood of the barbecue hood, performing all the steps according to the already established scheme: first, the sheet of metal is marked on suitable bending points, and then riveted to the frame base. The total dimensions of this part should be 40 × 126 cm (width / length).
7. At the end of the process, paint the finished hood walls with heat-resistant paint and install the structure on the brazier, fixing the base with self-tapping screws for concrete (relevant if the brazier is made of brick).

Features of the structure of the chimney made of brick

The construction of a brick chimney in many respects resembles the process of manufacturing a metal one, except that brick is used as a sheathing material for the construction. As in the first case, the base of the dome is an iron frame, welded from a durable metal corner, pre-treated with a primer and refractory paint. Refractory bricks are placed in a stepped manner on top of it, so that the upper part of the trapezoid is much narrower.

The chimney in such a structure can be made of fireclay or brick for the stove, which largely depends on the location of the barbecue. If it is located in an open area, drainage slopes are made on the walls of the smoke collector from heat-resistant roofing material so that moisture does not damage the entire structure during heavy rainfall. The umbrella above the pipe is often made of metal: steel (stainless steel is used) or created from sheet metal, but with a protective two- or three-millimeter coating.

Umbrella installation is performed in one of several possible ways:

1. From the ground with the use of racks, when metal pipes are welded to the corners of the smoke box on one side and dug into the ground and concreted on the other. Do not forget that in its widest part it must exceed the size of the grill.
2. On racks to a brazier (usually used for portable barbecue).
3. On cables or chains attached to the gazebo roof.

Important! All the components of the exhaust system of the brazier (base, dome and chimney) are fastened together using the same rivets, but for the convenience of performing all actions, it is better to connect the individual elements together during installation on the brazier, that is, at the last stage of its construction.

Alternatively, you can use the combined method of installing the umbrella, the essence of which is its combination with the barbecue in one structural element. This solution is relevant for the independent manufacture of a metal exhaust system, and it will work no worse than a brick one.

In general, despite the possible difficulties during the work, with a responsible approach to the construction of the hood for the gazebo and a clear calculation of the sizes of all the required elements, the creation of a functional product is quite possible. The main thing that is required from a summer resident is the presence of patience and a suitable tool, then there is every chance to save a decent amount of money on buying a finished hood.
