The maintenance schedule for the gas boiler. List: what is included in the maintenance of gas equipment. Check of automatic regulation

That is why scheduled inspections of boiler houses should be carried out. Maintenance is carried out by special certified organizations. In this case, the inspection includes a visual assessment of the parts and, if necessary, their repair.

The objectives of servicing gas boiler houses by a service company

Everyone wants a gas boiler house to last for many years. But its performance depends on many factors. Bad work provokes rapid wear of parts or their breakage.

Warn the problem can be regular checks, which are possible for warranty and post-warranty service.

After the end of the warranty period of work must pass six months before the first inspection. The regularity of such inspections and repairs is prescribed in the contract between the client and the representative of the organization. If there are problems between the checks, you should contact the organization, which will carry out repairs on request.

Objectives of service:

Control of automation parts;
Determination of the correct functioning of the burner;
Checking the operability of all parts.

Each goal affects the maintenance of quality work device. In addition, special attention should be paid to the gas supply and discharge pipes. It is necessary to evaluate the state of ventilation and chimney. Also, certain tests will be required to adjust the burners. Sealing of joints is checked with a gas trap and soap solution. All faults should be eliminated here. When the element can not be repaired, replace it.

Types of service of gas boilers during operation

Allocate 3 types of service: scheduled, current and major repairs. The first type is carried out with a certain periodicity. A schedule is made which should be observed.

Scheduled service tasks:

Maintenance of high-quality operation of the equipment by regular cleaning and lubrication.
Finding breakdowns and their elimination. When replacing obsolete parts, serious emergencies can be envisaged.
Replace elements that are not designed for long work. These include gaskets.

Current repair is performed when the system unexpectedly failed. Then the master is called, which eliminates the breakdown. Major repairs are carried out periodically at a certain time, which is indicated in the graph.

As a rule, major repairs are carried out every few years.

During the procedure, the critical elements of the boiler are changed or restored. An in-depth check is in progress to detect problems. At the same time, tests are carried out to check the performance of the parts.

List: What is included in the maintenance of gas equipment

In the operation manual, you can meet service requirements gas boiler. At the same time, the description of the work is quite extensive. To understand the need for such work, you should study the instruction in detail.

Maintenance operations:

Visual inspection of the boiler. Check the condition of the burner.
Certain parts of the system must be cleaned. These include ignition electrodes, fire sensors, a retaining washer.
Air sensors should be purged.
Purify, and if necessary replace, filters.
Elements of the boiler, which interact with fire, should also be cleaned. It is important to clean the gas burner itself. In addition, the system needs adjustment.
From the chimney it is necessary to remove the deposit. But this operation is not included in the service maintenance, it should be ordered and paid separately.
The electrical component of the boiler is checked and repaired if necessary.
Adjustment of the gas burner and other elements. Its adjustment takes place after determining the composition of the combustion products.
Adjustment of boiler operation, if it is connected to the system.
Checking the security system. This is an obligatory measure. The security team does not work constantly, so it is not possible to make sure that it is not faulty. But its correct work directly affects the safety of the whole family. The examiner creates an imitation of accidents, and checks.
Check the tightness of the solenoid valve, which blocks the supply of gas.
Check the quality of all gas supply connections. The elements should be evaluated for corrosion and tightness.

When performing a major overhaul, the heat exchanger needs to be cleaned. All operations should be done regularly. The quality of the equipment depends on the life of the whole family. Every detail must be serviceable.

Sequence of maintenance of gas boilers

Scheduled maintenance consists of cleaning, inspection and adjustment. Before operation, shut off the gas supply. After that, the system is given time to cool down. Further evaluate the state of the system by the appearance of the parts. The documentation and the guarantee seal are checked. Then they pay attention to all the elements of the system. Next proceed to cleaning, after cleaning the boiler.

Elements that need to be removed and cleaned:

Retainer washer. Determines the location of the burner relative to the heat exchanger.
The air sensor. Mixes air and gas.
Flame indicator. Tells you when traction worsens.
Electrodes of ignition. A mixture of oxygen and gas is ignited.

Any metal under the influence of fumes and soot is spoiled. During normal burner operation, the fire is blue. A yellow shade indicates the need for cleaning equipment.

The burner is cleaned with a special brush. In this case, the event should be held regularly.

Automation testing is considered the most important part of the work, since life depends on the efficiency of automation. The safety system includes a thermostat, gas valves and fittings, a controller, a pressure switch. The main thing in time to determine the presence of problems.

Choosing a boiler maintenance organization: the main rules

Not all boilers have service centers. Special organizations are licensed for this, having necessary equipment and specialists. Such a company receives a certificate for certain types of work.

Masters of the service center must be trained at the boiler manufacturer's factory. So they get the necessary knowledge to work.

To find out the qualifications of specialists, you should read all the company's documentation. There are a number of recommendations that should be followed when choosing an organization. These rules will protect you from scammers.

The location of the company should be as close as possible. Ideally, this is the same city or at least the region. So reduce the time for the arrival of specialists.
The organization must provide a certificate from the manufacturer.
It is required to draw up a contract with a detailed description of all the services and responsibilities of the parties.

Find out about the service centers on the website of the manufacturer of gas boilers. There should be a list of all organizations. This allows you to get a certain guarantee about the certification of organizations.

How the gas boilers are serviced (video)

Gas heaters need constant monitoring. It is necessary to evaluate not only the appearance of the elements, but also carry out certain checks of the system's quality performance. Servicing boilers can only companies with certain certificates from the manufacturer. Technical support will help to keep the equipment operational.

Carrying out inspections and repairs of gas units is one of the mandatory conditions safe operation heating and water heating equipment. After all, the round-the-clock operation of the boilers leads to their increased wear and tear. Prevention with the definition of existing defects can prevent emergencies. Who should carry out the maintenance of gas boilers and what kind of complex of measures it includes, consider in the article.

Each user of the gas boiler counts on its long operation. But the durability of the equipment depends on many factors.

Uninterrupted operation of the boiler leads to rapid wear of its working elements and assemblies, and unstable delivery natural gas - and at all to the premature disabling of an expensive device.

To prevent the disabling of gas boiler equipment only timely preventive measures, which are realized through warranty and post-warranty service

The first maintenance should be carried out according to the rules six months after the end of the warranty period. The frequency of technical inspections and troubleshooting is established on the basis of a contract concluded between the representative of the technical department and the owner of the equipment.

Malfunctions of gas assemblies detected during the period between ongoing maintenance operations are eliminated at the request of gas boiler owners by the employees of the organization with which the contract was concluded.

Service of the boiler is designed to solve at once three tasks:

To carry out the control of devices of automatic regulation.
Check that the burners function correctly.
Determine the current state of the internal heating elements of the equipment in operation.

Each of these aspects is of primary importance in maintaining the efficiency at the initial level and extending the life of the boiler system as a whole.

In addition, an employee of a gas facility that performs the maintenance of a gas boiler must inspect the condition of the cranes and connections of metal pipelines. He must assess the performance of ventilation and smoke channels, tightness of nodes.

During the current inspection, a visual inspection of the combustion of gas is carried out, if necessary, the burners are adjusted. Evaluation of the tightness of joints is done with a soap solution or with the help of gas detectors.

During maintenance of the gas boiler, an assessment of the technical condition of the entire system should be carried out: checking the tightness of joints, the operability of the cranes, the presence of traction in the ventilation risers and chimneys

All detected violations should be eliminated immediately after detection. The restoration of the operability of parts and mechanisms is carried out, in the event of impossibility of repair, replacement is performed. If necessary, the parts and components of the gas heating equipment are repaired in the workshop of the gas facilities with which a contract for maintenance has been concluded.

At the first sight, there is nothing complicated in carrying out preventive measures for servicing the boiler units. But it is not worthwhile to engage in independent tuning and cleaning of the gas boiler. And the question is not only in experience. Such a responsible procedure should only be performed by a qualified technician who has the exact technique necessary to diagnose malfunctions.

The quality of maintenance of boiler equipment directly depends on the professionalism of the master. Therefore, such work should be entrusted only to professionals who have special admission.

In the event of an unforeseen situation, the master will be able to respond correctly and quickly, thus preventing unjustifiably grave, sometimes catastrophic consequences

According to clause 6.2 of the current SNIP, boiler equipment maintenance services should be performed by licensed organizations that have their emergency dispatch service at their disposal.

Leading manufacturers of gas boilers, in order not to open branded service centers in each region of the country, issue licenses to organizations specializing in the field of maintenance.

In addition to the certificate for the performance of a given range of activities, such organizations receive full access to technical documentation for equipment manufactured by the manufacturer, as well as the opportunity to obtain new components for boilers for warranty replacement. A list of certified firms is usually listed on the manufacturer's website.

When choosing a service organization and drafting a contract, you should focus on two parameters:

Certification of the boiler manufacturer, which is confirmed by the availability of a license for the work.
The location of the service center in the same city or region, which will reduce the response time of the visiting master.

In most cases, the service contract is signed before the boiler is fully commissioned. It clearly specifies the list of future works and the timing of their implementation.

As a supplement to the contract, a boiler certificate is attached, in which all design features system, a complete list of its nodes and elements, as well as the timing of maintenance

The works offered by service organizations are divided into three types:

Routine maintenance - regular preventive work, conducted to assess the technical condition of the unit, identify and eliminate the maturing failures, to prepare the unit for the heating season and after its completion before the summer inactivity.
Service on the subscriber's request - includes measures to identify violations and damage to the system, diagnose the performance of the gas device or its individual parts, eliminate breakdowns and malfunctions.
Overhauling - a set of measures for the failure of the unit, conducted in the event of emergencies, provoked by external factors or as a result of equipment failure.

The regularity of preventive maintenance of equipment depends on the purpose of the installed boiler and its design.

The list of mandatory "procedures" for routine maintenance and overhaul, as well as the frequency of their execution is provided by the manufacturer to each specific model

On average, routine examinations are recommended to be performed 2 times a year. They are also carried out for devices included in the heating circuit, and for the units of DHW systems. Failure to meet the deadlines for such an important event can lead to serious consequences. Thus, the clogging of the pipeline can cause a malfunction heating system, and the depressurization of the gas pipeline - the cause of the explosion and fire.

The main stages of the current service

To fully master the situation, it is necessary to understand what works are performed when servicing various parts and assemblies. The current maintenance of the boiler operator includes three main types of work: cleaning, checking and adjustment.

Before performing service gas equipment necessarily cut off the system and gas supplies. The shutdown system should cool slightly.

Visual inspection of the heating system

At this stage, they form a general idea of the current state of the system in operation. The first thing the master performs is the verification of documents and the guarantee seal, determining the compliance of the installation of the gas appliance with the requirements of two main normative documents:

SNiPu - sanitary construction regulations and rules.
"Rules technical operation and safety requirements in the gas sector of the Russian Federation ".

Since the gas boiler is a combination of equipment for the operation of which both gas and electricity are used, electrical elements are also subject to visual testing.

For external inspection of the gas boiler from the unit, the protective housing is removed and all visible elements are sequentially examined, revealing the degree of deterioration of the parts

Checking the condition of the boiler is designed to clarify such points:

integrity of the device design;
pressure of the gas valve;
ignition electrodes in their presence;
state of the connections of the gas supply lines;
working capacity of electronics;
serviceability of emergency machines.

At this stage, you control and swap expansion tank, which is designed to protect the elements of the system and to compensate for the pressure that is created when the coolant is expanded.

During the technical inspection visually and with the help of devices, the state of the unit itself, of the protection devices and gas communications

Pressure level in the state cold water depending on the type of boiler is 1.1-1.3 bar. It is important to ensure that after heating the pressure does not exceed the recommended standard specified in the passport to the unit.

Cleaning the system elements

Before starting work, empty the boiler. After that, proceed to inspect the gas burner, determine the quality and direction of the flame. To do this, remove and consistently clean:

a retaining washer - a device that adjusts the position of the torch of the burner with respect to the installed heat exchanger;
air sensor - it is designed to regulate the air-gas mixture ratio;
the flame alarm sensor - it generates a signal when the traction indicators deteriorate;
electrode of the ignition device - responsible for igniting gas-air mixtures;

All metal constructions under the influence of high temperatures and deposition of carbon deposits can deform with time.

To ensure that the scale does not clog the burner, which is the key working element of the boiler, it must be cleaned in a timely manner, using special brushes

In the normal operation of the burner, the flame has the shape of a cone, painted in a blue hue. Yellowish color indicates its contamination. Check the operation of the key boiler operating element and assess the conformity of the burner settings with the composition of the supplied gas, as well as the completeness of its combustion, by measuring and analyzing the exhaust gases of the boiler.

Cleaning is subject to the fire area on the combustion chamber of the fuel and all parts of the boiler that are in direct contact with the torch. With this task, you can easily cope with using a soft brush and a vacuum cleaner. When cleaning the nozzles, do not use a metal brush, whose bristles can damage the surface.

Separately, unscrew and blow the gas channels of the boiler with air. The nozzle leading to the burner is removed, disassembled and blown under pressure.

The heating system is equipped with two filter elements. The first is located in the hydraulic unit, and the second one is on the crane with cold water. These filters also need periodic cleaning from salt deposits by washing.

As the maintenance is carried out, all faults found by the master are eliminated without fail, replacing the failed parts and components with new elements.

Check of automatic regulation

Boilers of modern production are equipped with automatic control systems, the main purpose of which is to ensure the operation of the unit without constant human observation.

The degree of complexity of automation can be very different. But regardless of the model, its main elements are:

Thermostat is a regulating device that is responsible for maintaining the set parameters of the coolant temperature in the boiler.
Gas valves - are designed to open and close the gas supply.
Gas fittings - an actuator designed to fulfill the commands of the boiler control circuit.
Controller - an electronic device designed to implement a complex algorithm for controlling the unit, depending on the changing environmental conditions.
Minimum and maximum pressure relays - membranes acting on groups of contacts, turning off the unit in the event of a fall / increase in pressure below / above the setting value.

Such a technique "painfully" tolerates a regular drop in voltage. The task of the master is to find out in time the problems in the electronic system and possible problems with the details.

Every year, a boiler, connected to a gas boiler, designed to provide DHW supply, must also be checked and regularly adjusted

To test the safety of the boiler safety system and identify the vulnerable parts of the equipment, the master simulates the emergence of an emergency situation. After starting the system, he observes the speed of the alarms, the tightness of the shut off valve and other devices.

If the automation is not working correctly, the unit is disassembled, and the failed membranes are replaced with new ones.

Inspection is subject and introductory part gas pipe. It is studied for corrosion and other damage.

The master must ensure the integrity of the supply pipeline during the whole site laid in the house, paying special attention outer surface of pipes and joints

All connections of the gas path, including flange, threaded and prefabricated, are tested for leaks. Measure the pressure in the gas pipeline. If necessary, adjust the gas valve. Places where the paint has peeled off the surface of the pipe is stained again.

Having adjusted all knots of boiler, the master exposes the parameters recommended by the manufacturer.

At the final stage, the boiler is finally tested. The master fills in the attestation documents, confirming with his signature personal responsibility for the quality of the performed check. Finally makes a memo indicating the period of the next service.

What does the overhaul include

After the specified in the passport for the product of the operating period, the gas boiler is subject to technical diagnosis. The main task of engineering and technical measures is to determine the possibility of further safe operation of equipment.

Major repairs are carried out for the purpose of restoration technical specifications gas heating equipment. As required, the worn parts and functional components are replaced.

In addition to diagnosing within the framework of the capital service, they perform:

Rinse out the heat exchanger.
Complex inspection and cleaning of all closed units of the boiler.

Correctly carried out complex of measures is a guarantee of serviceability of gas equipment operation during the subsequent service life.

The scum formed in the coil of the heat exchanger with improper maintenance leads to a gradual deterioration in the efficiency of the equipment

Cleaning of the heat exchanger from scale is carried out after the first five years from the moment the boiler unit is put into operation. Although most service organizations prophylactic flushing recommends that every two years. A simple procedure for flushing the boiler heat exchanger eliminates the problem at the stage of scale formation.

For capital cleaning, remove the device cover and disassemble all removable parts of the unit. Separately, the heat exchanger is dismantled and pumping station thoroughly washed with chemical reagents. Such washing allows to remove all the scale, which for several years was formed in the pipelines and fins of the heat exchanger. After this, the boiler is assembled and the system is filled with a coolant.

In addition to servicing the gas boiler itself and the gas pipeline leading to it, it is important to regularly check the condition of the chimneys

Cleaning of smoke channels designed to divert combustion products from gas appliances and create traction, the list of necessary for the implementation of the master of the event is not included. This work, he can perform for an additional fee. If desired, cleaning chimneys you can do it on your own. It is desirable to wash it at least once a year.

Operation of the boiler in case of force majeure

In case of an emergency, you must react as quickly as possible to the problem and try to return the boiler to working condition. Breakdowns, if they occur, just in the heating season. And the reason for this is most often the fact that the unit operates at maximum power without interruption for a long period.

The unit can fail at the most inopportune moment, a long period of working at the limit of possibilities, which leads to a rapid wear of the parts

To the same deplorable result often leads and low-quality fuel, which is often fed into the gas system.

Having a service contract, the owner can only call the organization. Upon receipt of the application, the repair team will arrive at the site and fix the problem.

Since in the service centers boiler records are always kept, the specialists of the visiting team arrive already with the necessary set of tools and spare parts that correspond to the specific model of the gas boiler installed in the house.

But there are situations when in the peak heating season repair brigades "on break". And the request to satisfy the master can not be as fast as one would like. Some owners in this case resort to the services of "private traders".

But it is worth considering that it is not the best option to call the first "gas man". And it's not even a round sum, which will have to lay out the owner. After all, no one guarantees that the master will be able to perform repairs at a high professional level in an emergency situation.

Therefore, in order to avoid such situations and save unnecessary expenses, it is worth not neglecting the possibility of conducting a current technical survey before the onset of cold weather.

Video: the sequence of performing the actions in the maintenance of the gas boiler:

Video guide for cleaning the burner:

The regular maintenance of the gas boiler allows us to identify the problems that have already arisen at an early stage and not bring the situation to the point where the operation of the equipment will start to pose a threat to the health and life of the household.

When choosing any technique, each homeowner prefers quality. Household gas equipment is no exception. Moreover, special requirements are imposed on him, for, for example, a gas boiler is designed for 24-hour operation. And such work invariably leads to increased wear, which can to some extent prevent the maintenance of gas boilers. But here there is another dilemma, how to understand what is included in the list of mandatory manipulations, and what will simply be the pumping out of money from the employee of the service organization? In our opinion, every landlord must understand what kind of procedures for servicing a gas boiler a qualified master must perform necessarily and in what order. In this article, we propose to understand what manipulations, by and large useless, can increase the cost of maintenance? In other words: how to avoid "hack-work" in the maintenance of gas heating equipment?

Before signing a service contract

Independently provide the service of a gas boiler is impossible - it's a fact. To do this, you need to have a special education, admission to the performance of such works, professional tools and instruments. Naturally, all these requirements will correspond to a representative of the service company. But before signing an agreement with such an organization to service a particular boiler model, it is worthwhile to find out what is included in the list of services. Then this list with a list of those works that are recommended by the manufacturer of heating equipment.

Checking the operability of the automatics responsible for safety. This is a very important moment of maintenance, implying an imitation of an emergency situation and evaluation of the operation of the corresponding devices in such conditions.
Determination of the correct operation, as well as the integrity of the shut-off valve, is another procedure that is interpreted as the maintenance of gas boilers.
Careful examination of the supplying pipeline, which is the responsibility of the owner of the house. Here, during inspection, special attention is paid to identifying corrosion of pipes, checking the tightness of existing joints (flanged, threaded, welded). If necessary, the gas pipeline is painted.

What does the capital service mean?

Approximately, after several years of full-fledged operation of the equipment, capital maintenance of the gas boiler is carried out. More specific terms are also specified by the manufacturer. Here, the primary efforts should be directed to washing the heat exchanger. It is impossible to perform this procedure without special equipment and reagents.

Operation of the gas boiler and "force majeure"

It will be relevant to describe the situation, which, unfortunately, is often found in life. So, in the street severe frosts and all gas heating appliances are exploited at the limit of possibilities. As a result, working parts and components wear out quickly. By the way, to the same result will result in poor-quality fuel, which is also often supplied to the gas system. In one word, the boiler failed at the most inopportune moment, and repair crews during this period, as usual at the break and when the consumer's application is satisfied, no one can say.

Malfunction of equipment is easier to prevent than repair

In order to somehow take the situation under control, it will be necessary to call the first "gas man" who understands the complexity of the situation and takes a tidy sum for services.

But whether to carry out repairs in an emergency situation at a high professional level, this is a big question. How to avoid such trouble? Of course, to have a contract for service with proven companies, whose specialists will perform all the work before the onset of the cold season, qualitatively and at an adequate price.
