Possible errors and their elimination

Explanation of errors
The manufacturer's instructions will tell you how to start the equipment correctly. It will function properly only if there is protection from voltage fluctuations and a ground line. Special mechanical filters are also required, because... remove solid impurities from water. If installation technologies are violated and there are breakdowns on the line, boilers may produce errors.

Using the self-diagnosis system

All Baxi devices have a self-diagnosis function. Failure data is displayed, the user deciphers the error code according to the instructions and takes action. The following may appear on the monitor:

• Index E and numbers 01 – no ignition. The sensor connection and gas supply are checked. Press R and hold for 2-3 seconds.
• E02 - the thermostat has tripped.
• E03 – normal traction has disappeared.
• E05 – temperature sensor is broken.
• E10 – decrease in pressure, loss of board contacts, breakdown of the relay or pump sensor. The malfunction can only be diagnosed and repaired by a specialist.
• Errors E96, 97 and 98 – failure of the electronic board. It needs to be replaced.

Blocking information may also appear on the display. It occurs when overheating or loss of traction. The user will need to reset the boiler.

Other breakdowns

In addition to errors, equipment failures are observed:

• The burner does not operate at maximum power. The pressure is set incorrectly or the gas valve modulator is broken. To fix the problem, the owner must configure the settings according to the instructions.
• The device turns on, but immediately turns off. The reason is low gas pipeline pressure. It is necessary to make adjustments to 5 mbar.
• The coolant practically does not heat up. The problem can be resolved by testing the gas valve pressure.
• Popping sounds when igniting. There is not enough pressure, the distance from the igniter to the gas supply has changed. To eliminate damage, the gap is adjusted to 4-5 mm.
• Modulation doesn't work. The valve is being replaced.

The concept of liquefied gas

In Russia, liquefied petroleum gas is usually called hydrocarbon gases (LPG) based on a mixture of light hydrocarbons liquefied under pressure with a boiling point from -50 to 0 °C. The composition of such gas can vary significantly; the main components are propane, propylene, isobutane, isobutylene, n-butane and butylene. Today, for autonomous gas supply systems, mixtures of liquefied technical propane and butane (SPBT, petroleum gas, corresponds to GOST 20448-90) are used, rather than liquefied natural gas (methane). The latter is stored at low temperatures in special cryogenic vessels, requires additional evaporators and is economically justified only for heating a large group of houses.

Liquefied hydrocarbon gas (LPG) turns into a liquid state with a slight increase in pressure. Then it can be easily transported and stored. With a decrease in pressure or a slight increase in temperature, the “liquid” gas begins to evaporate and enters the gas phase, ending in saturation. The saturated vapor pressure depends only on the ambient temperature and does not depend on the amount of liquid.

One liter of LPG produces about 0.25 m3 of gas phase. In winter, gas pressure decreases and gas phase supply performance decreases. If vapors are taken intensively (for example, turn on the boiler at 100% power), then accelerated evaporation of the liquid will lead to its cooling and, therefore, to a decrease in productivity. To obtain the required volumes of gases, the number of LPG containers is increased. Propane has an optimal set of necessary properties. It steadily supplies the gas phase even in frosty conditions, but is relatively expensive and good only in winter. In the summer, when it’s hot, its vapor pressure reaches the maximum value permissible for the walls of the vessel (1.6 MPa), so propane is diluted with cheaper and less intense butane.

LPG is not recommended to be placed in basements and even basements if the window area in them is less than 1 m2. Since complete combustion of SPBT requires a lot of air, good ventilation must be provided in boiler rooms. In addition, it is necessary to organize natural lighting in the room, as well as install a gas leak detection sensor and an automatic shut-off valve with self-powered power.

Types of Baxi gas boilers

The manufacturer has several classifications of units: by type of combustion chamber, by the number of circuits, by placement and type of operation.

• According to the combustion chamber : there are devices with an open and closed chamber. Closed-chamber boilers have a built-in chimney to maintain the flame and keep air in the house. Open chamber boilers are used in houses with a chimney; in the presence of natural draft, the burning gas will be removed.
• By placement : wall and floor models stand out. Wall-mounted ones are more convenient to place in small spaces; floor-mounted options are large in size and require installation.
• By type of operation : there are condensation and convection models. Condensing options are expensive, rare, and have high efficiency of more than 100%. Convection models lose some of the heat to the chimney.

His device

The main components that make up the boiler design are:

• Closed gas heating pad.
• A fan for supplying air to the combustion chamber.
• Primary (copper) and secondary (stainless steel) heat exchangers.
• Circulation pump.
• Expansion tank.
• Three-way valve.
• Safety valves that relieve the pressure of the heating water or domestic hot water in the event of emergency situations.
• A control board, a system of sensors that send signals to it in a continuous mode.

The boiler operates according to the usual method characteristic of all similar designs. Using a circulation pump, the coolant is supplied to the heat exchanger, where it is heated to the highest possible temperature.

At the outlet, it is fed into a three-way valve, which dilutes the hot heating agent with a colder return flow in a given proportion, determined by the set heating mode. After this, the prepared coolant is sent to the heating circuit.

Hot water is heated in a secondary (plate) heat exchanger and supplied to the distribution points. A closed combustion chamber improves the quality of indoor air.

To organize combustion in the required mode, air is supplied using a fan, which takes the required flow from the external compartment of the coaxial chimney.

How to choose the power of a gas boiler

To select the power of a gas boiler, you can use several methods.

The simplest is to calculate 1 kW of power per 10 sq.m. premises .

This simple approach is most optimal for small buildings with good thermal insulation and double-glazed windows with low ceilings.

In private houses, you should take into account the height of the ceilings and use the formula MK = Qt * Kzap, where MK is the boiler power, Qt is the heat loss of the building, Kzap is the safety factor, which is 15-20% of the design power of the boiler.

Application area of ​​LPG

Due to its environmental friendliness (clean combustion) and relatively low production and processing costs, propane-butane gas is widely used for the industrial and economic needs of the population. The scope of application of liquefied petroleum gas is wide. For example, LPG is used as a source of heat, fuel for vehicles, raw materials for the production of aerosols, etc.

The use of LPG as a raw material for home heating retains all the advantages of autonomous heating using natural main gas, with the exception of current gas costs. But it often happens that even with a relatively close location of the main gas pipeline, the prospect of connecting to the “cherished pipe” remains far beyond the horizon. In this case, you should approach the choice of fuel with a calculator. For example, let’s consider heating a 300 m2 cottage with three types of fuel: liquid (diesel) (DT), mains electricity and LPG. On average, such a room consumes 80,000 kW of energy per year for heating. Based on this figure, we will make the following calculations:

Table 1. Economic comparison of heating costs for a cottage with an area of ​​300 m2

Prices are valid for June 2011. Average gas consumption is 0.86 kg per 10 kW.

The presented table for estimating fuel consumption and costs shows a clear feasibility study for the use of LPG. Additional advantages of bottled gas, in contrast to diesel fuel and electricity, will be: the ability to organize various options for preparing hot water (boiler or flow-through heat exchanger) and minimal emissions into the atmosphere, unlike diesel fuel. Only NOХ, CO2 and steam will be emitted with flue gases. When using condensing boilers as heat generators, harmful emissions are reduced significantly, and gas savings can reach 30%!

Prevention recommendations

Prevention for the company's boilers is of a standard type, which includes annual maintenance.

In case of malfunctions, it is worth considering several points, including the fact that repairs should be carried out by a professional, since the system requires a careful and competent approach. Another important point is the need to replace parts with original ones if they break down. Do not install homemade or clandestinely produced spare parts. This will only lead to more serious damage.

Annual maintenance includes cleaning the chimney, which is mandatory, and removing scale. These operations must be performed at least once a year. Under optimal operating conditions, cleaning should take place every six months.

It is also worth considering that the operating mode must be regulated by technical characteristics and instructions. This will avoid most problems.
