Safety Permitted Uses 2 Safety 2.1 Safety Information D A N G E R Non-permitted use! Incorrect use of the boiler can cause severe injuries and damage! The instructions and information provided in the instructions should be observed! Details on procedure for operation, maintenance and cleaning, as well as troubleshooting for the boiler are included in the individual instructions.
Ensure that any faults, which might impair safety, are rectified immediately. The Fröling S3 Turbo is intended exclusively for heating up central heating water. Use only the fuels specified under 2.2.1. The manufacturer or supplier is not liable for any damages resulting from non-permitted uses.
Safety Design Information 2.3 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.
Safety Design Information 2.3.3 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.
We recommend that a draught limiter is fitted (1) Install the draught limiter directly under the mouth of the flue line, as there is always low pressure there.
