The first start-up of a pellet boiler should be performed by a specialist. The process, although seemingly simple, is a complex procedure in which you need to remember to perform the next steps. Why is it worth using the help of a specialist and what does the start-up look like step by step?

Is it worth starting a pellet boiler for the first time on your own?
In theory, starting the boiler yourself is possible, but it is associated with certain consequences. Manufacturers stipulate that during the first start-up of the boiler, the next steps should be performed by a specialist who has the appropriate knowledge and experience to properly carry out the process. Otherwise, if mistakes are made, you can even lose the warranty on the boiler. What is more, manufacturers impose the obligation of installation and start-up by an authorized installer or service technician. Such people have the appropriate training, which minimizes the risk of making mistakes.
Another issue that speaks in favor of entrusting the installation and start-up of the boiler to specialists is safety. These are advanced solutions, especially if the device is to be connected to the electrical and gas installations. If the pellet boiler is not configured properly during the first start-up, many problems may occur during use, including, among others, overheating of the device and leaks.
This in turn is associated with an increased risk of fire. During the first start-up of the pellet boiler, specialists will take care of its proper calibration and adjust all important parameters so that the whole thing works smoothly and efficiently. The settings include combustion parameters, fuel dose and air flow. Adjusting it yourself would be difficult, especially since professional tools will be necessary to set the right parameters.
Incorrect parameter settings can lead to numerous problems during use. Examples include inefficient pellet combustion or failure to achieve maximum energy efficiency of the stove.
How to check if the pellet boiler is properly connected before starting it?
To ensure maximum safety, before starting the pellet boiler for the first time, check that the entire installation has been carried out safely. First, check the tightness of the hydraulic system and the connection of the pellet boiler to the central heating system. It is very important to properly connect the supply and return pipes. In systems where the installation of an expansion tank is mandatory, check that it has been properly attached. If it is a closed system, an expansion tank will be necessary. In turn, in open systems, an open tank must be installed.
When checking the correct assembly of subsequent elements, it is necessary to pay attention to the shut-off valves. They are necessary not only for safety, but also for performing necessary service and maintenance work in the future. A similar check should be carried out in the context of safety valves and filters. If there are circulation pumps in the system, it will be necessary to check their operation and verify that they have been installed in the right places.
Pellet boilers require a proper connection to the chimney before starting the heating system. The pipe responsible for the discharge of exhaust gases must be very tightly connected to the chimney flue. The chimney itself must be unobstructed. Safety regulations specify the requirements that are imposed on devices dedicated to burning pellets. In order for the combustion process to be effective and safe, proper chimney draft must be ensured. The exhaust gas discharge system should also be checked.
The first start-up also requires checking the electrical installation - correct connection of the power supply and safety devices. Then, the control system should also be checked. If the thermostats and sensors, as well as the boiler control itself, are not set correctly, inefficient combustion will be observed during the pellet combustion process. It is equally important to connect the feeder, and before starting, measure the feeder's efficiency, which helps to optimize the boiler's operation. Before starting the boiler, the specialist will also assess the ventilation in the boiler room and perform a pressure test.
The process of starting a pellet boiler: Step by step
Starting up pellet boilers requires appropriate procedures. A pellet stove should be started after checking all elements that affect the correct operation and safety of the user. Hydraulic and electrical installation, connection to the chimney, proper ventilation and connection of the tank, which provides access to hot utility water not only in winter but also in summer.
The next step is to fill the system with water and bleed it. Removing air from the system is necessary for the correct and optimal operation of the radiators and ensuring thermal comfort for users. Then you can start the furnace and configure the controller.
In the last stage, you should load the feeder and light the boiler. It is very important to observe the combustion process, because the pellet should burn cleanly and evenly. When the operating temperature stabilizes, you still need to adjust the power of the device and perform combustion regulation.
