Changing the fuel to one other than the one recommended by the manufacturer is not allowed and the responsibility for such action lies solely with the User. The consequences of incorrect operation of the boiler resulting from the above do not constitute grounds for considering the incorrect operation of the boiler as a physical defect of the product. -
Page 10: Basic Information On Combustion Of Wood-Based Fuel
Altereco B1 type wood chips are delivered to the customer in plastic bags weighing about 14 kg and transported on pallets (fig. 15), the packaging method protects them from excessive moisture, but does not release them from storage under a roof, in order to avoid the direct impact of adverse weather conditions that may reduce fuel quality. -
Page 11: Basic Information On Burning Wood Chips
Relationship between water content and fuel humidity The amount of water in fuels is given as either water content or fuel humidity. The water content (in %) refers to the moisture content of the fuel or the fresh matter (LSD) and the moisture content of the fuel to the completely dry matter (SS). -
Page 12: Basic Information On The Combustion Of Wood Pellets
Definition of size classes of wood chips according to EN ISO 17225-4 (a) The number in the size class refers to the maximum particle size in the main fraction. The particles must fit into a round mesh sieve (ISO 17827-1) of the size determined for that class in mm. The lowest possible property class must be given. (b) The length and area of the section should be determined only for particles in the coarse fraction. -

i.e. pressed into a cylindrical shape. The raw material is stored and transported in perfectly dry conditions. The plant operator must also store the pellets in a perfectly dry place. This is the only way to guarantee correct and efficient combustion. Requirements for wood pellets For combustion in the boiler, wood pellets with a diameter of 6 mm and a length of 3.15... -

3. construction and technical data of the boiler Boilers of GHT series are welded steel sheet structures. Fuel combustion takes place in the combustion chamber . Above the chamber there are ceramic catalysts (picture 14), whose task is to afterburning the gases and other volatile compounds that escape during combustion, reducing their emission outside (they help in more accurate afterburning of fuel). - Page 16 Drawing 3. basic overall dimensions of the GHT 22 kW boiler - front view.

Before setting up and connecting the boiler, it is necessary to check that all components are operational and that the boiler is fully equipped for operation. 4.3. Installation of the boiler in the boiler room The boiler doesn't need a foundation. It is placed directly on the floor. It should be exactly levelled! The strength of the floor as well as fire protection conditions must be taken into account. -

equipped with a factory supply, control or fuel feeder system (for automatic boilers) in a closed type installation, provided that a safety valve, diaphragm vessel, control and measurement fittings (pressure gauge, thermometer, etc.) are installed, and that the requirements for boiler operation are met, in particular the recommended operating temperature of 45-75°C, maximum permitted temperature of 85°C, maximum permitted operating pressure 1.5 bar. - Page 23 Solid fuel boilers can also operate in closed heating systems. Specially adapted boilers are used for this purpose, which are equipped with devices for receiving excess heat, protecting the system against overheating. ● In this system, a closed diaphragm pressure vessel is installed on the site of the expansion vessel overflow.
