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 factory
installed on left side of the boiler (wood), and thermal safety valve (7) should be installed according to
Scheme 2. On right side of the boiler (wood pellet) is also factory installed heat exchanger with factory
installed thermal safety valve. 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 public 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:
Left side of the boiler (wood):
Thermal protection for left side of the boiler BioTec Plus consists of a
heat exchanger
which is factory
built in boiler, and
thermal safety valve (7
) (such as CALEFFI 543 513) (see Scheme 2).
Thermical valve (
7
) is installed into prepared connector (male thread 3/4") in the upper part of left
lateral side of the boiler casing.
Right side of the boiler (wood pellets):
Thermal protection for right side of the boiler BioTec Plus consists of a
heat exchanger
which is
factory built in boiler, and
thermal safety valve
(11)
which is also factory built in boiler.
INSTALLATION (according to Scheme 1.):
Left side of the boiler (wood):
- 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 city plumbing cold water
inlet and the connection
(5)
(inner thread 3/4") 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").
Right side of the boiler (wood pellets):
- fix the connection
(9)
(inner thread 3/4") to the city plumbing cold water inlet.
- fix the tube connected to the sewage outlet at the connecting point
(10)
(outer thread1/2").
