Pellet store Fire safety regulations
71
Minimum clearances for outdoor fuel stores:
• When setting up a pellet storage container
in open air, maintain clearances from buildings and
property boundaries according to state building
legislation.
Temperature monitoring system in fuel store/pellet
bin:
• In accordance with TRVB H 118, an alarm
thermostat must be installed above the conveying
hose where it exits the fuel store, or the pellet bin.
This alarm thermostat is not required for an ETA
pellet system since the ETA rotary valve with
pressure equalisation ensures that no gas can flow
in either direction between the combustion
chamber and the fuel store. This has been
confirmed by tests at the Institut für Brandschutz-
technik und Sicherheitsforschung (institute for fire
protection engineering and safety research) in
Linz.
Fire safety regulations in Germany
In Germany, the specimen ordinance on combustion
equipment (Muster-Feuerungsverordnung MFeuVO,
version dated September 2005) is the basis for fire
safety regulations. Below are the most important rules
from these regulations. Since there are minor
variations among the states, get information from
specialists such as the local master chimney sweep.
