3 Technical requirements
i
If this device is not used, both connections
must be sealed shut. False air will otherwise
be drawn into the burner, which will impair bur-
ner performance.
–
The extinguishing device must be connected eit-
her 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 amount 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 inlet opening in the feeder is to be configured
in such a way that blockage through 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.
–

TRVB 118 H
Manually triggered extinguishing device
(MTED)
–
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.
–
This device consists of an empty pipe with a mini-
mum nominal size of DN 20 and is to be installed
in the fuel storage as specified by the manu-
facturer of the firing system directly above the deli-
very line in front of the wall or ceiling passage in
such a way that the greatest possible success
can be achieved in extinguishing. The empty
piping must be connected directly to a pres-
surized water supply and provided with a shut-off
valve arranged in the boiler room. Mark this valve
with a sign "Extinguisher - Fuel Storage Room".
–
The execution of the extinguishing system must
be done so that damage during fuel feed or from
the extraction device is not possible. In addition,
make sure that the fuel supply to the delivery line
is not affected.

back safety, backflow of gases:
Abb. 2-6: Rotary valve
–
Complies with requirements regarding burn-back
protection devices (BPD) according to TRVB 118
H.
–
Prevents backflow of flammable products of com-
bustion into the fuel supply (according to EN 303-
5).
–
Prevents fire spreading into the fuel supply (accor-
ding to EN 303-5).
Safety switch on the trough cover
Opening the channel cover interrupts the power sup-
ply to the auger motor.

Connect the safety switch
Heating system encompassing several fire
compartments
If the boiler room and fuel storage room are located in
different fire compartments, optional equipment must
be installed in addition to the factory safety equip-
ment, e.g.
–
a temperature monitor (TM)
–
a manually triggered extinguishing device (MED)
