accordance with the law of every country in which the boiler is assembled. Always keep the
written documentation of the last calibration data for the safety valve.
•
On the return line assemble at least another pressure safety valve.

The valve of thermal safety by swelling (Figure 6)

This safety element also has a role of a limitator of temperature. Below it will be marked
with the abbreviation VTO.
In some extremely dangerous situations in the transformation of water into vapor is such
that the pressure safety valves are not sufficient to ensure the safety of the hydraulic
system. For this reason, the installation of VTO is mandatory. Depending on the
regulations of the countries in which the boiler is assembled, it is necessary to install
theVTO only for the determined higher powers or for each power of a boiler it is the
obligatory to instal the VTO.
Place the installation is shown in the Assembly diagram of boiler onto the installation in
Figure 7
The boiler is supplied with a copper coil so it is necessary to use the VTO with trhe
exchanger, as shown in Figure 6. Cold sanitary water is brought to the VTO. When the
VTO-probe has the information that the temperature is over 95 degrees the VTO is
opened and water flows through copper coil. After some time the temperature of water in
boiler returns to its normal state.
One connection of coil is used for VTO and the other for draining of water that has
passed through the coil. The choice of either connection; for VTO or for the discharge is
irrelevant. It is necessary to follow the installation instructions provided by the
manufacturer of the VTO.
Be sure to check up, in certain periods of time, the functioning of the VTO.
