6.22 Sound insulation
Braces
To avoid the transmission of structure-borne noise during the opera-
tion of the fuel transportation equipment, the braces and the anchors
of the relevant conveyor device are placed on high quality Sylomer
bases (plastic anti-vibration mounts for noise attenuation) or anchored
with a Sylomer support and a fixing plate in the building structure. The
anchors with heavy load anchors are separated from the braces with
Sylomer washers.
Standard delivery:
■ Sylomer washer
■ Sylomer support
■ Sylomer base
■ Fixing plate for the braces of the relevant equipment

Note
■ For each different means of fuel transportation, the sound insulation
article should be used once. Example: 1 AH + 1 sound insulation
AH-AS.
■ Installation room characteristics relating to the physical building
structure largely determine the transmission of structure-borne noise
in the building. It is important to note that the specified measures do
not offer full sound insulation.
■ Building related measures (brick openings, fire barriers, floating
screeds, etc.) must be coordinated with structural engineers and
architects and are not part of standard delivery and therefore not
within our area of responsibility.
Appendix
7.1 Sizing the expansion vessel
In accordance with EN 12828, water heating systems must be equip-
ped with a diaphragm expansion vessel. The size of the expansion
vessel is subject to the heating system specification and should be
checked in each case.
