General Standards, Design, Assembly 1 General information CAUTION Assembly and installation by untrained personnel. Risk of personal injury and damage to property. The instructions and information provided in the manual must be observed. Assembly and installation must only be carried out by qualified personnel (heating installers or licensed electricians).
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. Always comply with all fire, building, and electrical regulations when installing or operating the boiler system, in addition to following the operating instructions and mandatory regulations that apply in the country in which the boiler is operated.
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 close to opposite each other as possible to achieve a good thermal draught effect. The supply air must be drawn in directly from outside. Exhaust air must be discharged directly outside.
General Standards, Design, Assembly Combination with storage tank In accordance with the relevant Austrian laws governing energy technology, which are based on Art. 15a B-VG “Agreement on protective measures for small furnaces” dated November 1994, no buffer storage tank is required on manually fed biomass boilers that have been positively tested at both rated load and partial load (below 50% of rated load) to ensure they adhere to the emissions limits specified in that agreement.
General Standards, Design, Assembly Other guidelines are based on tank size, e.g..In Austria: Specific subsidy guidelines for Austrian states (e.g. Styrian state government guidelines: buffer storage tanks of at least 800 L) ... In Germany: “BAFA Förderung” guidelines on measures to promote a better use of renewable energies of the Federal Office of Economics and Export Control (BAFA): buffer storage tanks of at least 55 L/kW...
