- Flue temperature values refer to an air inlet
temperature of 15°C.
approved with the HE 30 COMBI INTERNAL,
components 60/100 and 80/125 mm.
- The max. sound level emitted during boiler
operation is < 55dBA. The sound level value is
referred to semianechoic chamber tests with
boiler operating at max. heat output, with
extension of flue gas exhaust system according
to product standards.
