When and how often it is necessary to clean

Every 1-2 years, all reputable manufacturers advise performing routine preventive maintenance. In actuality, cleaning requirements vary depending on model and operating circumstances. The heat exchanger for two to three seasons is greatly overloaded when used as a coolant during a hard, fluctuating water season. More soot is produced by atmospheric burner boilers, and the dusty environment hastens the clogging of the primary burner and litter.

For each of the three heating seasons, we advise cleaning the gas boiler at least once. If not, it’s important to watch out for any indications that one or more of the boiler unit’s components are clogged:

• slower heating and lower temperature of the room at the previous power settings;
• an increase in gas consumption;
• the appearance of extraneous noise during operation (increased noise when the water moves in a heat exchanger or strong pops during ignition, indicating the clogging of a litter or burner);
• the presence of previously not characteristic odors in the boiler room;
• Problems with ignition, when the fiber does not reach the main burner or is absent at all;
• reverse traction is observed, the boiler goes out for no apparent reason.

If at least one of the aforementioned issues is present, it is imperative to examine and, if required, clean the affected individuals as well as, ideally, all potential components as outlined in the instructions below.

Cleaning wall gas boiler: step -by -step instructions

Prior to taking any further action, it is advisable to block the gas supply crane (or ensure that it is blocked), turn off the boiler’s main supply, block the boiler’s supplier and reverse lines, and, if available, block the feeding and dowel contours.

Despite having a more intricate and dense layout, cleaning the wall gas boiler is quicker and easier. The front panel must be removed in order to access all nodes and elements; it is typically fastened with two self-tapping screws from below. Certain models have the option of an additional internal protective lid.

Turbine

Since not every model has a turbine, you can move on to the next section if your model does not have one. It is situated immediately before exiting the chimney, above the combustion chamber. A higher uneven noise is an indication that it has clogged.

1. Remove the turbine by unscrewing the appropriate screws and disconnecting the condensate assembly (there is no need to disassemble it).
2. On the back there is a fan, the blades of which need to be cleaned of dust and dirt with any brush.
3. If necessary, lubricate its bearings.

Heat exchanger

Reduced boiler heat production, increased gas consumption, extraneous noise when the coolant moves, and increased circulation pump operation are all signs that the heat exchanger is clogged.

1. To access the heat exchanger, we remove the front of the combustion chamber, some models may require dismantling and upper cover.
2. Using the brush, clean the ribs of the heat exchanger, first longitudinally, then across. Be careful with the force of pressure so as not to bend and not break the plates.
3. If the boiler is double -circuit, it is necessary to clean the heat exchanger of the hot water, which is usually located in the lower part of the case. Some budget dual -circuit models are equipped with a bitter (double) heat exchanger, externally – this is one element, as in single -circuit models.

It is required to flush (internally clean the heat exchanger of scale and other deposits) at least once every three to four years when using hard water in every season. every five years, with a variable softened coolant.

A gas boiler’s heat exchanger must always be removed in order to be cleaned, with the exception of the most efficient method, hydrodynamic flushing. Although it is not advised to do it alone and requires an expensive booster, it can be completed at home by a team of experts without the need to transport a heat exchanger.

For easier chemical cleaning:

1. Drain the water from the boiler through the corresponding crane.
2. Strail the pressure.
3. Typically, on the heat exchanger nozzles are located sensors of the duct and temperature to remove the heat exchanger, they need to be disconnected.
4. Disconnect the fasteners, disconnect the pipes and remove the heat exchanger. Be careful because water is pouring from it, do not allow it to get on the electronics of the boiler. It is better to cover it with any waterproof material.
5. Having removed the heat exchanger, place it in a container with a solution of citric or hydrochloric acid (100-200 grams per bucket of water is enough). Leave it in the solution for 30-40 minutes.
6. Clean the remains of the scale and dirt on the outside, rinse the coil inside with a special brush inside. Bittermic (double) heat exchangers of double -circuit models in view of the structures are not subject to internal mechanical cleaning.

Following the conclusion of all steps, thoroughly dry the heat exchanger and rinse it with clean water before reinstalling it. Please be aware that chemical internal cleaning is not advised to occur more frequently than every two to three years. We have previously covered the steps involved in cleaning the heat exchanger in one of our earlier articles.

Burner and electrodes

In hinged models, the main burner is instantly set on fire by the ignition electrode, eliminating the need for traditional fabrics (pilot burners), making the system easier to clean. An unreliable ignition, an ignition containing a lot of cotton, or even the inability to ignite at all are indications of clogging. errors related to the ionization sensor (also known as the flame control sensor) on models with self-diagnostics.

The ignition electrode and flame control sensor may be shared or integrated, depending on the model. Certain models come with an ionization sensor and two electrodes. Nevertheless, it is not hard to identify them; just follow the example in the picture below.

Use a brass or auspicious brush to clean the burner on a gas boiler; the most important thing is that the brush be sufficiently soft so as not to scratch the boiler’s exterior. Electrodes can also be used to clean the same brushes; some people also use wool-milestones or rubber gasket erasers. You can use alcohol and cotton wool.

The only thing that needs to be checked is that the electrodes and burner are free of dust, soot, or precipitation from the heat exchanger, as well as any kind of damage or scratches that could exacerbate future soot accumulation.

Consequently, it is advised that you clean the combustion chamber’s inner surfaces entirely before gathering the boiler as a whole.

Gas filter

It is positioned in front of the gas supply line’s locking reinforcement and is essential for removing potential contaminants and impurities from fuel that could accelerate the formation of soot and contaminate the combustion chamber and chimney. Gas filters are not always installed, despite their advantages. Regarding the cleaning:

1. Unscrew and remove the roof.
2. Remove the plug from the flange.
3. Pull the hair cassette or metal mesh, depending on the type of filter.
4. Shake well and blow it to get rid of pollution, you can also rinse it with benzene or other solvents. Collect and install the filter in the reverse order.

All the components that are susceptible to pollution are now cleaned. Verify that you have accurately gathered every component of the boiler unit (if you lack experience, it is preferable to snap a picture prior to disassembly) and get going.
