Failures of the Beretta gas boiler occur for various reasons. To make it easier for you to fix the breakdown, the manufacturer has provided a self-diagnosis system. It includes monitoring sensors that detect problems in the nodes, sending a signal to the control module. After that, the operation of the device is blocked, and an error code appears on the display. To eliminate the characters, it is necessary to find and eliminate the malfunction.
Features of Beretta boilers
Gas boilers of the well-known company "Beretta" are represented by floor and wall models. Among them there are convection and condensation options. Consider the features of each of them.
Most Popular wall units: Beretta City 24 CSI, Beretta Super Exclusive. Some models include the useful Winter-Summer mode. It allows you to switch the heating temperature to save fuel.
Management is mechanical with regulators and electronic with a display. It is possible to connect a remote control. Double-circuit boilers are equipped with a plate-type secondary heat exchanger. A pressure gauge is available to monitor pressure.
A closed combustion chamber takes air from the street, it is considered safer to operate. Coaxial chimney can be connected both in the apartment and in a private house.
Novella and Fabula rulers present outdoor appliances. The control panel is hidden behind a sliding cover. In the presence of temperature regulation, thermometer, protection sensors. Burner with two adjustment steps. Novella series is equipped with two radiators that work on different circuits.
Condensing units use combustion energy more efficiently. To the usual efficiency of 90–95%, another 5–10% is added due to the energy of combustion of gases. These are the lines of Minute Green, Exclusive Green. Among them, you can choose options with one and two circuits.
The modulation burner automatically mixes gas and air in equal proportions. Switching to liquefied fuel is possible. Read more on the Beretta Gas Boilers Overview page.
Errors and malfunctions
If this is the first time you see a trouble code on the screen, try resetting it by rebooting the boiler. If the code does not disappear after switching on, then check its decryption.

Other malfunctions
Not all problems are indicated by an error code. If you notice deviations in the operation of the Beretta gas boiler, our recommendations will help.
The smell of gas in the room. Close the shut-off valves, ventilate the room, contact the gas service.
The smell of smoke, carbon monoxide. Clean the chimney from soot and debris. Check that there are no foreign objects from the street above the shaft opening.
The burner ignites late. Inspect the gas valve. Clean the burner and nozzles from dust. Adjust flame settings (modulation).
The boiler is operating normally, but the batteries are cold.. Vent excess air from the system using Mayevsky taps. Check pump operation, set a different speed. Inspect the expansion tank for serviceability. Replace if there is a problem.
Now you know how to restore the equipment. In some cases, an appeal to the master is required. For example, if there is a gas leak or to replace the control board.
