General Standards, Design, Assembly 1 General information C A U T I O N Assembly and installation by untrained personnel. Danger: Personal injury and damage to property. The instructions and information provided in the instructions should be observed! Only allow trained staff (heating installers or licensed electricians) to perform set-up and installation! 1.1 Notes on standards The boiler must be installed and started up in compliance with local fire...
General Standards, Design, Assembly 1.2 Design Information It is forbidden to carry out modifications to the boiler or to change or deactivate safety equipment. In addition to the operating instructions and the applicable regulations for the country in which the boiler will be operated for installation and operation of the boiler system, all fire, police, and electrical regulations must be observed.
General Standards, Design, Assembly 1.2.3 Ventilation of boiler room The openings for the supply air and the exhaust air should be arranged as nearly opposite each other as possible to achieve a good thermal draught effect. The supply air must be drawn in directly from outside. The exhaust air must be discharged directly outside.
General Standards, Design, Assembly 1.2.6 Chimney connection / chimney system EN 303-5 specifies that the entire flue gas system must be designed to prevent, wherever possible, damage caused by seepage, insufficient feed pressure and condensation. It should be noted here that flue gas temperatures of less than 160 K above room temperature can occur within the permitted operating range of the boiler.
General Standards, Design, Assembly 1.3 Installation Information Water lines should not be located in close proximity to the storage area or the feeder units due to the dangers posed by condensation and bursting water pipes! Check the delivered items for foreign objects in the individual components.
General Standards, Design, Assembly Potential equalisation When connecting the hose lines to the individual connection pipes, ensure there is potential equalization throughout the line! Expose approximately 3 cm of the earth conductor at the end of the hose line TIP: Slit the insulation open along the wire with a knife Bend the earth wire inwards in a loop This prevents the earth wire from being damaged by the feed of pellets.

Installation Install delivery system Sloping floor Fig.1: Store for a delivery unit with a suction probe Fig.2: Store for a delivery unit with a screw The under-floor structure should be dimensioned so that the sloping floor is not deformed when subjected to static load. You should ensure that the pellets can slide down smoothly.
Installation Connect pellet boiler 3.5 Electrical Connection R I S K Working on electrical components. Danger: Serious injuries from electric shocks. Work on electrical components should only be carried out by authorised technicians Flexible sheath conductors should be used for the wiring which should be measured in compliance with the applicable regional standards and guidelines The supply line (mains connection) must be fitted with a max.
Installation Connect pellet boiler 3.5.1 Connecting the Comfort pellet box The connection of the Comfort pellet box to the pellet module board is established using a flexible cable (5x0.75mm², e.g. YMM as per ÖVE- K41-5 or H05VV-F as per DIN VDE 0281-5). This is a 24V control line.
Initial startup 4 Initial startup 4.1 Configuring the boiler The boiler must be configured to the heating system on initial start-up. N O T E Optimum efficiency and consequently efficient operation with low emissions can only be guaranteed if the system is adjusted by qualified technicians and the specified factory settings are observed.
