point. The valve may be installed verticaly or horizontaly, but the discharge must always be facing
downwards. It must not be install upside down. The valve should be installed at the uppermost
point of the boiler.
When pellet is used as fuel, there is a risk of overheating also.
Remedy
The boiler BTA is equipped with safety thermostat, which in case of water
temperature excess above 95
0
C, interrupt the power supply of regulator. In that case the
dosing system stops, and pellet is not enter into the boiler.
Connecting the control panel of boiler to the network
When installing the boiler, power supply cord must be connected to the boiler. The power supply
is single-phase 220 V, 50 Hz. Installation must be performed by an expert because there is a
danger of electrical shock.

- the pressure in the boiler and installation,
- whether complete installation is properly vented,
- whether boiler cables do not rely on the warm (hot) portions of the boiler or the cables are not
physically damaged,
- before feeding pellets into the reservoire, check that there are no mechanical hard objects that
could impede the work of the screw conveyor.
In a closed heating system the installation of a certified expansion vessel (figure 2a,
poz.7) is requred to avoid hydraulic shock. Locking element must not be installed between
the safety valve, expansion vessel and boiler. Expansion vessel is not supply with the
boiler and must be installed in the central heating system.
Water temperature in boiler may not fall below 55
0
C not to cause condansate.
