3.25 COMBUSTION PARAMETERS.
3.26 TECHNICAL DATA.
- The maximum 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.
