Schematic 17.2 BVTS Valve
The emergency extinguisher, that prevents from combustion of fuel in the tank, can also be
connected to the water system. In case the set temperature is exceeded, the extinguisher opens the
water valve and activated regardless of the power supply.
Due to the design of the SEG BIO series boilers, there is a very little probability that the fire gets
into the fuel tank. It is prevented by the tight construction of the feeder with a stop; levelling device
that levels the pressure in burner chamber and fuel tank.
ATTENTION!
The gas pressure in the expansion vessel should be checked before use and
properly adjusted. The vessel should be inspected once a year.
ATTENTION!
The safety valve should be installed in the heat source or its closest vicinity e.g
power cable to the system in an easily accessible spot.
ATTENTION!
The safety valve should prevent the max excessing of work pressure no more than
10%
18. Requirements for the expansion vessel
(INSTALLER)
Every open water heating installation should be equipped with an expansion vessel, which
receives excess water volume and deaerates the installation. The vessel should be installed in the
top-most point of the installation, and if possible, vertically above the boiler (boilers).
The capacity of the vessel should be calculated using the unit capacity for every kW of power at
1-2 dm
3
.
The expansion vessel is equipped in stubs to connect a riser safety tube, safety downpipe, and
a spill pipe and - connected to it - deaeration.
The diameter of the deaeration and spill pipe should be at least
[MM]
- Boiler efficiency [kW]
The most important requirements on the operation of the device are the following:
 The expansion vessel should be about 3.5% of the total water volume in the water heating
installation and boiler.

Each boiler must have a safety tube and spill-pipe.
 Installation should be equipped with a signal pipe and expansion pipe, and a stub for
deaerating the expansion vessel.
In the case of several boilers, each should have its own safety pipe in accordance with the
guidelines in PN-91/B-02413. Safety and spill pipes should not have any closing valves, and the pipes
and vessel should be protected from freezing.
19. Connecting the boiler to the power supply
(INSTALLER)
The boiler is designed for 230V/50 Hz voltage. Such connection should be carried out by a
certified specialist. The 230V/10A connection socket with grounding should be easily accessible. The
power supply to the boiler and room lighting should have own circuit.
The finishing and heating test should be noted in the Warranty Card. the Warranty Card should
then be sent over to the manufacturer in order for the user to be registered in the company system.
ATTENTION!
First start-up of the boiler must be performed solely by service personnel trained by
the manufacturer, holding a current Authorized Service Technician or Distributor
certificate issued by METAL-FACH, or by a person holding an Electrician's license up
to 1.5 kW.
ATTENTION!
All the pumps, mixers, transmitters, ignition etc. are not parts of the controller
equipment.
