  • Page 15 Boiler room In Austria, no more than a week's supply of wood may be stored next to the boiler. For pellets, a separate storeroom EI90 (F90) with a EI30 (T30) door is required. As a result of amendments to building laws, up to 10 tonnes of pellets may be stored in the boiler room in some states.

  • Page 17 Safety Safety devices Heat dissipation is limited by the selected maximum flow temperature in the heating circuits and the target hot water temperature. Safety shutdown by safety temperature limiter For additional safety against boiler overheating, a safety temperature limiter is built into the boiler. When a boiler temperature of 100 °C (tolerance +0°/-6 °C) is reached, the power supply to the draught fan and the fuel intake is interrupted.
