Measurements according to EN 3746: 2010
Alt.1 The sound level of the burner can be reduced by equipping the burner
with silencer. Installation must be done so it does not prevent air supply
to the burner.
Alt.2 The burner’s noise level can be reduced by connecting the burner’s air
intake to the air duct that opens into an appropriate location. Installation
must be done so it does not prevent air supply to the burner.
