2 Safety information
EMERGENCY OFF switch
–
The EMERGENCY OFF switch is a manually ope-
rated safety device. The burner and the fuel supply
to the boiler are stopped. Circulation pumps remain
in operation to dissipate heat and cool the boiler.
–
The switch must be installed outside the heating
room in a safe place that is easy to access.

Install EMERGENCY OFF switch
Temperature monitor in the fuel storage
room (TM)
–
Required according to guideline TRVB 118 H for
wood chips, depending on system design, heating
capacity and fuel storage quantity.
–
Functioning: On the channel of the fuel delivery
auger, a temperature sensor of a protected design
must be installed in the area of the wall penetration
(inside the storage room). When a temperature of
about 70°C is exceeded, the warning device is
(optically or acoustically)triggered.

device (ATED)

1 Pocket sleeve for temperature sensor
2 Connection for water discharge
–
Functioning: If at the temperature sensor
1
the
temperature exceeds 50°C (direct extraction) or 95
°C (downpipe extraction), the valve
2
opens and
floods the feeder channel with water.
–
This extinguishing device serves to automatically
suppress burn-back within the feeder. Due to the
proper nature and location of the fire detection
element, burn-back must be reliably detected and
the extinguishing device must be triggered instanta-
neously and automatically (this must be ensured
even in the event of a power failure).
–
The extinguishing device must be connected either
directly to a pressurised water supply or to a water
reservoir (Note: Domestic waterworks may also be
affected in case of power failure).
–
The water supply must be equal to three times the
volume of the feeder equipment, but at least 20
litres. The container must be equipped with a fill
level monitor, including connection to the warning
device (temperature monitor
). The extinguis-
hing water inlet opening in the feeder is to be
arranged and executed so that blockage by
delivery operation is not possible and this can
easily be checked at any time. The routing of the
extinguishing system must be made as a non-
combustible version.

–
This extinguishing device is used to combat a fire
source in the fuel storage room, or fuel storage in
the area of the extraction/delivery line. The trig-
gering must be done manually.
