Approval of the project for the installation of a gas convector in Minskoblgaz. Installation of a gas convector

D. Sytov

From a technical point of view, a gas convector is a fairly simple device. Accordingly, its installation may seem a simple matter. However, there are a number of rules and nuances, the neglect of which can lead to incorrect operation of the device or even to an accident. Consider the basic rules for installing a gas convector

Installation of a gas convector is regulated by the following documents: DBN V.2.5-20-2001 "Gas supply"; DNAOP 0.00-1.20-98 "Rules for the safety of gas supply systems in Ukraine"; NAPB A. 01.001-2004 "Rules of fire safety in Ukraine".

Mounting the gas convector on the wall

The installation of the convector should be carried out in the place of the greatest heat loss in the room, ideally under the window. But here one important nuance arises: there should not be flammable objects and structures near the device. It is strictly forbidden to hang it with curtains, curtains, etc., since the body of the device heats up significantly during operation.

Included with the convector, some manufacturers include wiring diagram(template), which shows the places for fixing the device to the wall and the exit point coaxial chimney. When choosing a mounting location, it is important to ensure that the distance along the outer wall between the coaxial chimney and the ground level is at least 0.5 m, and from the nearest window - at least 0.25 m. It is also necessary to take into account the possibility of snow drift, which can block the outlet combustion products. Indoors, the device must be installed in such a way that the distance between the lowest part of the convector (usually the rear wall) and the floor is at least 0.10 m; for the best quality convection, this distance should be 0.20-0.25 m. The distance between the device and the side wall should be at least 0.18 m. 10 m (Fig. 1).

Rice. 1. Placement of the gas convector

coaxial chimney

Installation of a coaxial chimney is carried out in a pre-punched (drilled) hole in the wall. Here problems of a purely technical nature may arise, because the removal of combustion products and the intake of combustion air in gas convectors occur naturally, and therefore the outer diameter of the chimney is large enough. Basically, the diameter of the hole in the wall, depending on the requirements of the manufacturer, should be 0.16-0.20 m. daunting task if the wall is made of durable material.

The length of the coaxial chimney in most models is a maximum of 0.59 m, i.e. the thickness of the wall on which the device is installed should not exceed this value. The minimum wall thickness may be less than 0.20 m, but the manufacturer does not guarantee normal the operation of the convector and the achievement of the parameters specified in the technical data sheet, due to the large heat losses of the building. The chimney must be mounted in such a way that the air intake pipe is located flush with the plane outer wall and protruded 0.035 m into the room. In addition, in order to avoid moisture entering the apparatus, the slope of the coaxial chimney by 2-3 degrees should be taken into account. Outside, a protective cap is attached to the chimney, which, firstly, prevents the ingress of foreign objects, secondly, it serves as protection against wind blowing and knocking down the burner flame.

Gas convector installation errors

a coaxial chimney protrudes from the wall (fig. 2). This installation option leads to frequent shutdown of the device due to the increased likelihood of wind blowing. V winter period in severe frosts, the combustion products will be strongly cooled, which will lead to the formation and subsequent freezing of condensate inside the chimney;
the coaxial chimney is not installed tightly. The consequences may be frequent malfunctions of the device;
incorrect slope of the chimney. In addition to incorrect operation of the device, this leads to moisture ingress and, as a result, to corrosion and destruction of the heat exchanger;
narrowing the diameter of the gas supply. For stable operation of the convector, gas must be connected by a pipe, the diameter of which is indicated in the passport. Reducing this size can lead to the loss of the pilot burner flame, non-ignition of the main burner, spontaneous shutdown of the convector, and a decrease in power.

It is important that the gas convector be mounted on a non-combustible surface in accordance with DBN standards (insulation with roofing steel over asbestos sheet at least 3 mm thick, plaster, etc.) at a distance of at least 30 mm from the wall. The insulation must protrude beyond the dimensions of the enclosure. Violation of these standards may lead to damage to the material of the walls or
even to the fire.

From the author: welcome, dear friends! We offer to talk about how to do the installation of a gas convector with your own hands . These heaters are less popular among consumers than their electrical counterparts. The fact is that this type of heaters implies the presence of a centralized gas supply or a gas cylinder. But such models are much cheaper to operate. They are usually installed in cottages or in country cottages- that is, in those locations that do not need constant heating.

Device device and principle of operation

Let's start with the definition of a gas convector. This heater is not an analogue of a gas boiler. It works on a completely different principle - it does not heat the coolant, but the air. installed in relatively small rooms, as they heat the air locally.

The design of this heater is relatively simple. The gas convector consists of the following parts:

heat exchanger in which air is heated;
programmer- a device responsible for maintaining a certain temperature in the room;
control panel, on which the indicators are displayed;
gas valve, controlling the gas supply;
fan #1 responsible for supplying air to the heat exchanger and valve;
fan number 2, dispersing the heated air around the room.

How does a gas convector work? Everything is quite simple: it functions on the principle gas burner. Cold air from the outside, obeying the laws of physics, enters from below, heats up and exits through the hole at the top of the device. Note that gas models can function due to natural or forced convection. In the second case, air is blown by fan No. 1.

Pros and cons of individual gas heating

Please note that the quality of the device, as well as the duration of its successful operation, directly depend on the price of the gas convector. Is it possible to buy a cheap unit and connect it in the house? Yes, but keep in mind that an inexpensive model will last you no more than a year. At the same time, it is unlikely that such a convector will be repaired if it fails.

Consider the advantages of gas heaters, based on the fact that you did not save money when buying and purchased a quality unit.

Advantages of gas convectors:

the room heats up quickly;
economical use of fuel;
the device can be easily installed indoors by yourself;
democratic price;
the gas convector does not need to install a heating system;
does not destroy oxygen in the room;
the heater can be mounted to gas cylinder;
the device works offline;
if the convector works according to the principle natural circulation, then it does not depend on the power supply.

Important: gas convectors with a closed combustion chamber can be installed safely in any room, including the bedroom .

Cons of gas convectors:

in order to properly install a gas convector with connection to a centralized system, it is necessary to obtain permission from the relevant municipal authorities;
gas convector connection diagram requires punching through hole in the outer wall of the building, in the place where the device is planned to be installed;
impressive size;
if you plan to use several gas convectors for heating an apartment or house, then each of them will have to be individually supplied with gas outside the building.

Important: experts insist on choosing models with a built-in fan. They are more efficient than similar natural convection appliances.

Necessary tools and installation diagram

The next step after purchasing the device is preparation for installation. Make sure you have the following materials and tools on hand:

pipe cutter;
drill;
drill;
wrench;
spanners;
screwdrivers;
perforator;
scapula;
silicone (sanitary, high-temperature);
self-tapping screws and dowels;
gas cock.

Now you can proceed to the next step - choosing the installation site.

It is important to act according to GOST! Before you proceed with the installation, carefully measure, mark and "fit" the convector. Please note that the room in which you plan to install the heater must be prepared. Remove the furniture from the room or cover the furnishings with plastic, as punching can be quite a dusty business.

Installation of a gas convector is carried out according to the following scheme.

Decide where the opening for the gas pipe will be.
Make a hole in the wall with a puncher, focus on the diameter of the future pipe. This stage is the most laborious.
The next step is to drill holes for the heater mounts, hammer in the dowels.
Connect the convector to the exhaust pipe. Be sure to seal the joint with silicone that can withstand high temperatures.
The heater is attached to the wall with self-tapping screws. At this stage, you will need help, because the unit has an impressive weight.
The final stage of installation - blow holes and cracks with foam to avoid cold air entering the room.

We bring to your attention an educational video dedicated to installation.

Gas connection

Friends, at this stage it is important to be extremely careful! Let's say that you do not have the skills to work with gas appliances - then it is better to contact specialists to perform the following work.

Installation of a gas heater to a gas supply source is carried out according to the following algorithm.

Let's imagine that there is a special branch with a thread on a gas pipe. Then you just need to screw a gas valve onto this pipe. If there is no special withdrawal, then it will need to be done!
The next step is to bring the gas pipe to the convector and connect them with a fitting. This process is not rushed.
Fix the connected pipe with special clips. The distance between them is 1 meter. To do this, it will be necessary to drill holes on the outer wall of the building.
Treat fittings and pipe joints with silicone to ensure tightness.
Be sure to call a gas service representative so that he can verify that the installation and connections are correct.

Starting the equipment and checking the functionality

Before you start using your new heater, it is important to carry out a trial run. You should act according to this scheme.

Open the gas cock and check the system joints for leaks.
After checking, you can turn on the convector. For the first time, the start button must be fixed for 1 minute and wait until the gas enters the combustion chamber.
See that the burner is lit? Now you can adjust the operation of the convector.

Important: installation of a gas convector in wooden house absolutely safe, because the fire hazardous parts are located in the inside of the heater.

Summing up, we note that although gas heater- this is not a very popular device for heating, it can be used to create a comfortable temperature in summer cottages and in country houses. The unit quickly and efficiently heats the air in the room, and at the same time is much more economical than an electric radiator. Another obvious plus is the ability to connect to a gas cylinder. One dubious circumstance can be considered that it heats only one room, and not the whole house, in contrast to a gas boiler connected to the heating system.

We hope that the article was useful and helped to solve the problem!

Installing a gas convector in a wooden house has both pros and cons.

Features of use

First of all, people are concerned about the issue of safety, because wood is a rapidly flammable material, which means that when installing such equipment there are risks of fire, and the positive action coefficient of gas converters leaves much to be desired.

On the other hand, the installation process is much simpler than batteries filled hot water, for the supply of which it is necessary to mount a bulky heating system.

There are not rare cases when the original project of a wooden house did not provide for any heating at all, but during the operation the owner changed his mind, and installation of heating devices is required after the fact. Many gas convectors can quite satisfy such needs, because they are able to work on gas supplied from a cylinder, and not from a mains.

In order to obtain permission to install a gas convector in a wooden house, you need to make a visit to the gas or fire service, depending on the source of the gas, but first things first.

Requirements for the premises

Requirements of gas services for premises:

Ceilings should be at least two and a half meters, which is important, because many wooden houses built with low ceilings, and this is with the most low-power equipment;
The ventilation channel must be equal to or greater than 100 mm in diameter, the material from which it is made must comply with SNIP, and the lower part ventilation duct must be at least 200 mm below the ceiling;
The bottom gaps interior doors must be at least 25 mm;
Each room should have windows that allow ventilation;
The boiler room must be equipped with a door to the adjacent non-residential premises, and when installing a boiler with a power of over 150 kW, a separate entrance door;
The internal space of the boiler room must be at least 7.5 m3 in volume, for new houses this requirement has been doubled;
Chimney - must be equipped with two walls, its diameter must exceed or be equal to the inlet pipe of the equipment;
Lighting in the boiler room must be safe; for this, open light bulbs without shades are not allowed;
In the case of external wiring, it must be placed in specialized cable channels;
The indoor gas control system must be installed in a wooden house if the boiler is located in the basement.

Installation of a gas stove and convectors

It is forbidden to install the convector at a distance of less than 4 meters from open sources of fire, including gas stove. The hose suitable for the convector must have a dielectric insert, this will prevent a fire in the event of a short circuit in the wiring in a wooden house.

An important factor is the grounding of sockets located near the gas stove and convectors, although in a wooden house they must be grounded a priori.

There are three types of supply hoses that are allowed to a gas stove in a wooden house, namely:

Rubber fabric - its plus is that it does not conduct electric current, but it is more susceptible to mechanical damage compared to analogues;
Metal sleeve - when using it, a dielectric insert is necessarily inserted from the gas stove to the main, and otherwise it has the best performance among analogues. In addition, it is recommended by the latest approved standards. Its only disadvantage is the price, it bites;
Rubber with a metal braid - it is more able to withstand severe shocks, and also, thanks to the rubber core, does not conduct current.

When buying a hose, pay attention to the colors, on its sheath there are characteristic yellow colors used only for marking gas equipment.

When buying a metal hose, you should pay attention to its coating, some manufacturers oriented to other markets, with other standards, use yellow insulation, which does not fulfill its main functions. Always ask for supporting documents when purchasing, and keep them in a safe place.

The main advantages of gas convectors for wooden houses

All the complex nuances that needed to be clarified before choosing this equipment dismantled, it remains to list advantages of gas convectors for wooden houses:

Profitability - if a wooden house is assembled in accordance with the rules and does not have shrinkage crevices, then a very small amount of gas will be required to heat it;
The smallest boiler allows you to heat the room with total area up to 350 m3, and this is the size of a huge house, but subject to ceilings at the level of 2.5 meters;
Exists double-circuit boilers, which will supply your wooden house not only with heat, but also with hot water, the price for them is slightly higher, but the pluses are on the face;
Both automatic and manual ignition can be used to supply heat to the convector;
Provided that the ventilation standards are met, the natural outflow of gas is carried out without difficulty, and the danger of their accumulation is not observed.

The process of installing a gas convector in a wooden house

There is nothing easier than fixing the converter to wooden wall, for this you will need:

self-tapping screws;
Crosshead screwdriver;
Mounts (comes with the converter);
Building level;
Pencil.

First you need to check how far apart the loops are, for which the gas convector is hung. Most often, they are wide enough, which allows you to move it to the left and right already on the mounts, at a distance of about 5 cm.

Measure the distance between the centers of the seats, for the upper and lower loops it will be the same. Transfer these dimensions to the wall, observing the height you need from the floor, most often it ranges from 10 to 20 cm.

The self-tapping screws used must be at least 40 mm long, this will ensure a secure fixation to the wall in a wooden house.

Screw on the screws at the indicated points, and double-check with the help of the convector whether the distances match by bringing it to the heads of the screws. If so, then you can safely fix the hooks to the wooden wall.

When the fasteners are screwed, put a level on them and check the slope relative to the horizon, it can be leveled by loosening one of the fasteners and slightly raising it. Now you can hang the gas convector on a wooden wall.

Gas supply to the convector

Close the gas valve in front of the meter.

This process requires special attention in any room, and even more so when it comes to a wooden house. The main thing here is to check whether all the gas supply elements correspond to the description of the accompanying documentation.

Ball valves with a yellow marking on the handle are screwed onto the convector. Before starting, they must be in the closed state. It is necessary to fasten a hose or sleeve to the gas cylinder or line, be sure to check for the presence of a paranitic gasket in the union nut of the hose.

The next step is to connect the other end of the hose to the tap installed on the gas convector. Here you should also check if there is a gasket. After you need to compress all connections with ring wrenches.

Calculate the force, it is important not to transfer the gaskets, otherwise the gas will pass through the damaged parts of the system.

Now you can open the gas and taps on the convector. Using a shaving brush, apply the lather solution to all joints. After making sure that there are no leaks, you can proceed to the first start-up.

The first start-up in a wooden house is made with windows open for ventilation.

How to install a gas convector with your own hands

Required Tools and materials:

Metal-plastic pipe with metal fittings;
Pipe cutter;
Wrench for threaded connections and fittings;
Silicone sanitary;
Gas valve;
Perforator with a blade-shaped crown;
Drill and drill;
Phillips screwdriver;
Mounting foam high temperature;
High temperature silicone;
Plastic dowels with self-tapping screws to them.

The first stage, one of the most important - choosing a place for installation. According to GOSTs, it must be installed under the window. To be honest, I don't know what this is about. Moreover, I have seen that convectors are installed at a sufficiently large distance from windows.

Having chosen a place for installation, you need to try on the convector to the place. It is convenient to do this with the help of a tape measure, by transferring the dimensions, or, which is more reliable, by attaching the convector to the wall and marking the holes.

The next point is also important - the location of the gas inlet. If it is located at the bottom of the convector, it is necessary to leave a sufficient distance to bring a pipe with a clamp fitting to it.

Then, based on the diameter of the exhaust pipe, we punch through a hole in the wall using a perforator. This is the most dusty and time-consuming process. You need to be well prepared for it. Cover in advance, as much as possible, with plastic wrap.

Then drill holes for fasteners and drive dowels into them. Install the exhaust pipe into the opening of the convector. Treat the joint with high temperature silicone. Holding the convector with your hands, insert the pipe into the hole in the wall. Attach the convector to the wall with dowels. This is not easy, because the convector is quite heavy. Ask someone to help hold it. Some do it differently, but this method has been tested by me many times. I find it the most convenient. The result was a convector screwed to the wall and a chimney pipe sticking out to the street.

Blow out the remaining gaps between the pipe and the wall with high temperature foam. Put on a special cap designed to protect the burner from blowing in the wind on the end of the pipe. It is included. This cap is attached with self-tapping screws, also included in the kit.

So the convector is installed, now let's connect the gas.

Gas supply to the convector

According to GOST, it is necessary that the pipe that goes to the convector pass along the street. So let's do it. If the gas pipe has a threaded connection made in advance, then you just need to screw a gas valve onto it, which cuts off the gas supply to the convector. Well, if the pipe is without a drain, it will be necessary to do it. This work can be done by a gas welder. Ideally, a specialist from Gorgaz or a similar office.

After the gas cock is installed, run metal-plastic pipe to the convector. Using a tape measure, we calculate the length of the pipe, and the number of fittings.

By the way, when buying fittings and a pipe, make sure you have a certificate of conformity required for this kind of work.

Now install the pipe, attach it with clips to the wall every meter. To install the clips, drill holes in the wall. When installing the pipe, lubricate both the pipe and fittings with silicone for additional sealing. In addition, silicone will facilitate the installation of pipes, as it will serve as a lubricant.

As a result, we get a convector that hangs on the wall, an exhaust pipe, a cap and a gas pipe fixed to the wall and connected to the convector.

We start the gas convector

Immediately before starting, we open the gas valve and go through all the joints, fittings and threaded connections with a brush moistened with a small solution. Dishwashing liquid is excellent for this purpose. If you see bubbles rising, turn off the faucet immediately and fix the leak. I forgot to say - at this moment it is better not to smoke.

After repacking the joints, start the convector. To do this, press the gas supply button and do not release it for about a minute so that the gas fills the pipes and enters the combustion chamber.

Now press the piezo ignition button. A spark will ignite the gas and a blue, cheerful blue flame will ignite in the combustion chamber. In case you did everything right :).

Adjust the operation of the convector to obtain a comfortable temperature.

At first, for about a few hours of operation, the presence of an unpleasant smell of burnt oil is allowed. It's not scary - the convector is new - the combustion chamber is warming up and burning. However, if the smell does not disappear for a long time, you need to turn off the gas and carefully examine the junction of the outlet of the convector and the exhaust pipe.

Attention: All of the above work is best done by a specialist. Do not forget - self-installation gas convector leaves you without the right to repair it under warranty. And of course, the convector must be accepted by Gorgaz, and for this a tie-in project is needed. As well as all the necessary permits and the conclusion of the commission for acceptance into operation of the device.

However, having gained this knowledge, you will be able to supervise the installation of a gas convector by hired contractors.

A chimney-convector, or as it is also called an economizer, is especially relevant for stoves with low efficiency. Let's look at the principle of their work, as well as how they can be made by hand.

Scope of the chimney-convector

There are three types of convectors: water, electric and gas. The installation of a chimney-convector is required only on gas heating systems and sauna stoves.

Chimneys-convectors are successfully used for an accelerated rate of heating of adjacent premises, which is carried out by taking heat flows from the gases leaving through the smoke. In addition, they serve as a protective mechanism against the infrared radiation that comes from the chimney. They are easy to install. They are also easy to operate. If the design is simple and without a fan, then the presence of electrical wiring is not required.

The chimney-convector can be mounted in two ways:

connecting the pipe to a common chimney;
arrangement of its own smoke exhaust system.

Advice! The second method will allow you to heat two rooms at the same time. For example, a convector is installed in one room, and a chimney is installed in another. Such a system is ideal for a bath with a relaxation room.

The principle of operation of the convector

It lies in the fact that heat transfer occurs by convection currents, which form convectors. In fact, this is a constant circulation of air flows through the body or a closed chamber, which occurs from the bottom up, due to the fact that cold air is heavier than hot. Combustion products are emitted into the chimney of the convector.

The chimney for the furnace is most often made of metal pipes. You can mount the structure on your own without the involvement of specialists. It is necessary to correctly calculate the length and height of the chimney, assemble the chimney and insulate it with high quality.

The coaxial design of such a chimney consists of two pipes:

In the center is a chimney pipe, around it are air pockets, passing through which the air is heated:

the first is central. It is designed to discharge combustion products into the environment;
second. It is an external circuit designed to capture cold air. It is he who prevents the system from heating up to significant temperatures.

Advice! Converter chimneys are suitable for operation even in cold winters, so it can be safely installed in the system. It is only necessary when choosing to focus on models that have a rather large clearance of the chimney.

The second design option could be:

It involves smoke from the chimney and water in the barrel, which circulates after heating through the pipes

the central pipe is made similarly to the first variant and is connected to a gas heating furnace;
the second is made in the form of a barrel surrounding it, with two pipes for water circulation. Water is heated from the chimney pipe and heats the room.

Chimney-economizers are safe for indoor installation. Since it is arranged according to the type of coaxial pipe, it can be installed in the walls of the room, the material of which is wood. Read more about and bookmark the article.

Do-it-yourself converter chimney

Gas converter chimneys have a simple device, they can be made by hand.

At its core, the convector is a large-diameter pipe with pockets welded on it, which can be made of pipes of a smaller diameter, a rectangular metal profile or metal plates.

Metal chimney converter

To make an iron converter chimney is within the power of those who know how to use a welding machine.

Step-by-step instruction:

Step 1. You should take a pipe with a diameter similar to that coming out of the furnace (usually at least 15 centimeters), and cut it to the length of the chimney. On average, it is 55 centimeters.

Step 2. You need to take a pipe with a diameter of 5-7 centimeters and cut it into 6 parts, 45 centimeters in size.

Step 3. Weld 6-8 of the resulting blanks to the main one. They should form a complete circle around it.

Step 4. The chimney convector is ready.

Step 5 Connect it to the pipes.

Advice! After the converter is ready, for better heating it should be painted black, and for an aesthetic look it can be covered with some interesting overlay made of metal or galvanized sheet.

Chimney convector made of stainless steel

Stages of creation:

Step 1. You need to purchase a stainless thick chimney pipe and a sheet.

Step 2 Using rivets, attach a stainless steel sheet to the main pipe in large waves.

Step 3. The convector is ready.
