The user who has a service contract with an organization can request the elimination of incorrect heating functioning.

The following goals are pursued by the procedure:

  • Monitoring the control system of the device;
  • check the operation of the burners;
  • Determination of the condition of internal heating parts in the used device.

These elements contribute to preserving the unit’s initial efficiency level and extending its lifespan.

What is included in the list of services

The list of tasks completed by the service is determined by the type of boiler room and is governed by the boiler’s manufacturer’s instructions.

On the list are:

  • inspection of the equipment;
  • installation of the input panel;
  • Check the expansion tank;
  • Detecting the operability of safety devices;
  • control of power supply, exhaust and supply ventilation, as well as the chimney;
  • replacement of filter cartridges and nozzles;
  • Cleaning of the dirt filter elements;
  • Examination of the functioning of actuators, gate valves and circulation pump.

The master examines the burner operation algorithm, automation settings, and the device’s internal and external conditions.

Execution of the process

You must understand how to fix the device’s different parts so as not to damage it. There are various steps involved in routine maintenance, such as inspection, cleaning, and adjustments. It is essential to turn off the gas supply source and the system before beginning any work. Next, give the disconnected system some time to cool down.

Inspection of important components

To determine the equipment’s condition, this step is essential. In order to ascertain whether the installation conforms with the Building Regulations and the rules of use, the documentation is first examined, and the warranty seal is created. The boiler needs gas and electricity to operate, so make sure to check the electrical components as well.

The unit’s protective casing is first removed, and each component is then inspected individually to determine how worn it is.

The purpose of the inspection is to ascertain:

  • faulty operation of the emergency circuit breakers;
  • The presence of pressure in the gas valve;
  • condition of the ignition electrodes, if any;
  • the integrity of the construction;
  • functioning of the electronics;
  • The electrode responsible for ignition of the air-gas mixture.

Following the regulation and inflation of the expansion tank, which safeguards system components and balances the pressure generated during the heating medium’s expansion. The unit, safety components, and gas lines are examined using specialized equipment. There will be 1.1–1.3 bar of average cold water pressure. The precise amount varies based on the kind of machinery. The value should not exceed the number given in the boiler documents after heating.

Cleaning of contaminants

The apparatus must first be emptied, and the gas burner must be examined to ascertain the direction and quality of the flame.

Parts that need to be taken out and cleaned in order are as follows:

  1. Support washer. A device that controls the position of the flare in relation to the installed heat exchanger.
  2. Air sensor, which regulates the ratio of gas and air mixture.
  3. A flame signaling device that is triggered when the draught decreases.
  4. The electrode responsible for igniting the air-gas mixture.

Metal structures deform due to high temperatures and carbon deposits settling. Since the burner is regarded as a crucial component of the device, scale buildup should not occur in it. Special brushes are used to clean the component. When the flame is blue in color, the burner functions normally. If the element’s color has turned yellow, contaminants need to be eliminated.

The flue gas in the boiler must be measured and examined in order to evaluate the burner’s settings and ensure that it is operating properly. A soft brush and vacuum cleaner are used to clean the combustion chamber and every piece of equipment that comes into contact with the flame. The nozzles should not be cleaned using a metal tool with stiff bristles. The pipe that is meant to supply the burner with gas needs to be taken out, disassembled, and blown under pressure.

The heating system has two filtering components, one on the cold water supply tap and one in the hydraulic section. These filters get deposits of salt, which must be cleaned. All malfunctions are fixed during inspection, and damaged parts are changed out for new ones.

Functionality check

The mechanism of automatic regulation, which can vary in complexity, allows the unit to operate unsupervised. There are frequently voltage fluctuations with this technique. It is advised to fix electronic problems right away and make necessary system adjustments.

Every year, the boiler that supplies the DHW system through the gas boiler connection needs to be inspected.

An annual inspection is required of the boiler that supplies the DHW equipment and is connected to the gas boiler. A simulated accident is required to determine the safety unit’s condition and to pinpoint the device’s weak points. Following such an incident, keep an eye on the alarms’ speed, the tightness of the valves, and other details.

Should the device malfunction, disassembly and replacement of the diaphragms are necessary. Additionally examined is the gas connection’s inlet portion. The pressure level is ascertained and the entire gas pipeline is inspected, paying particular attention to the outside pipe connections. Should a fitting adjustment be necessary, it is made. The product is painted when the paint on the pipes cracks.

Following completion of the work, the equipment needs to be inspected and the manufacturer’s indicators need to be set as per the documentation. The paperwork needs to be completed by the foreman, who also needs to note the date of the next service.

Short about the repair of boilers

Repairs are made, replacing any damaged parts, to get the device back in working order.

Apart from diagnostics, the service consists of:

  • flushing of the heat exchanger;
  • Inspection and cleaning of the closed areas of the unit.

Scale builds up inside the heat exchanger, decreasing the device’s efficiency. Every two to five years, it is cleaned. By flushing the device, you can solve the issue before it even arises. This requires taking the device’s casing off and disassembling its components in order to perform a thorough cleaning of the area.

After being disassembled individually, the heat exchanger needs to be chemically cleaned. Following the completion of these steps, assemble the boiler and add coolant to the system. Chimneys must be regularly inspected, either by cleaning them yourself or by hiring a chimney sweep.

Check for leaks and corrosion Inspect and clean combustion chamber
Test safety controls and pressure relief valves Flush and refill system with inhibitor
Inspect and clean flue and vents Check and adjust burner settings if necessary
