Logano plus SB315, SB615, SB745 - Buderus

9 Installation9.6.3 Boiler supports to prevent the transmission of structure-borne noise, and sound insulation stripsBoiler supports to attenuate structure-borne noiseprevent the transmission of structure-borne noise to thefoundation and the building, and are used in combinationwith the Logano plus SB315 and SB615. They arechannel sections, into which Ω-shaped longitudinalattenuation brackets are inserted ( fig. 56). Thelongitudinal attenuation brackets are made of spring steeland are coated with an anti-drumming mass to prevent theradiation of air-borne noise. When a load is applied, theyare compressed by approx. 5 mm.When designing boiler supports to attenuate structurebornenoise, bear in mind that the installation height of theboiler and therefore the position of the pipeworkconnections can vary. To compensate for the springdeflection of the longitudinal attenuation brackets and tofurther minimise sound transmission via the waterconnections, we also recommend installing pipecompensators in the heating water lines.L GR1234B GR5B SB B442(39) 1) 6 720 642 881-39.1ilFig. 56Boiler support to attenuate structure-borne noise for the Logano plus SB315, SB615 and SB745 floorstanding condensing boilers (dim. in mm)1 Boiler2 Channel section3 Longitudinal attenuation bracket4 Foundation5 Side catch1) When subject to a loadThe standard delivery of the Logano plus SB745 includesspecial sound insulation strips to attenuate structurebornenoise which are made from 12 mm thickpolyurethane ( Fig. 57).3Fig. 571Positioning the sound insulation strips with theLogano plus SB7451 Position of the sound insulation strips116 720 648 053-26.2T86Technical guide Floor standing gas/oil condensing boilers Logano plus SB315, SB615, SB745 – 6 720 802 589 (2012/01)
