2.7.2 Requirements at the installation site
▪ All walls and load-bearing elements must support the static load. The structural
requirements may need to be discussed with a structural engineer. Local fire
regulations must be respected.
▪ Water lines should not be located in close proximity to the pellet store or the feeder
units due to the dangers posed by condensation and bursting water pipes.
▪ Pipes that cannot be removed at justifiable expense and which intersect the path of
the pellets during filling should be clad to protect against the flow and prevent
breakage (e.g. deflector plate, wooden boarding). The cladding should be designed to
divert the pellets without damaging them.
▪ There must not be any electrical installations such as switches, lights, distribution
boxes or other ignition sources in the pellet store. The necessary installations must be
explosion-proof and installed according to the locally applicable regulations.
▪ Doors, windows and hatches to the pellet store must open outwards and be fitted with
a dust-proof seal all the way round, to prevent dust escaping from the store,
particularly into other rooms.
▪ The system is only suitable for interior rooms, which are frost-proof and protected
against the elements.
