Boiler thermal protection
5.2.1. BOILER THERMAL PROTECTION
According to European EN standards, boiler thermal protection
must be
installed in
closed heating system. Boiler is factory prepared for installation of thermal
protection. Heat exchanger is built into boiler at factory, and thermal safety valve 7
should be installed according to scheme 3. In case of any damage of boiler installed
in the closed heating system due to its overheating, and boiler or system are not
equipped with any thermal protection at all, or do not have properly installed thermal
protection, guarantee will not be applied.
IMPORTANT:
Thermal protection must be connected to the water supply installation of the
premises supplied from the water supply line and not from hydrophor. Namely, in
case of failure of power supply, boiler could be overheated, and then hydrophor is
not able to ensure required water supply.

Thermal protection for boiler Bio-Tec consists of a
heat exchanger
which is factory
built in boiler, and
thermal valve
7 (such as CALEFFI 543 513) (see Scheme 3.).
Part 7 is installed into prepared connector (male thread 3/4") in the upper part of
left lateral side of the boiler casing.
screw the thermal safety valve sensor 6 (outer thread1/2 ) into the sleeve joint 2
(inner thread1/2 ).
- fix the connection 4 (inner thread 3/4 ) of the thermal safety valve to the sanitary
cold water inlet and the connection 5 (inner thread 3/4 ) through the reduction to
the connection point of the heat exchanger 1 (outer thread1/2 ) - the arrow shows
the direction.
- fix the tube connected to the sewage outlet at the connecting point 3 (outer
thread1/2 ).

8.0. ELECTRIC CONNECTION
All electrical works must be performed by a certified professional in accordance
with valid national and European standards.
A device for switching of all power supply poles must be installed in electrical
installation in accordance with the national regulations on electrical installations.
Detailed description of connecting the sensors and operation of digital regulation is
displayed in the Technical manual "Digital boiler regulation Bio-Tec".
