2.1 Installation on the hydraulic system
During the connecting to the hydraulic installations, the boiler has to be
adequately secured so that the maximal temperature and pressure is not exceeded.
Central heating fitter is responsible for adequate installation and
connecting of the boiler to the hydraulic system.
Radijator Inženjering, as the manufacturer of the boiler, does
not take any
responsibility for the damage caused by inadequate installation of the boiler.
2.2 Measures and safety devices
For safe operation of boiler it is necessary to assemble and maintain the following elements in
working condition:
Pressure Safety valve (figure 2),
The valve of thermal safety by swelling (Figure 4).
Figure 2. Figure 3.
Pressure safety valve must be of nominal diameter of 1/2 inch calibrated to a maximum
of 3 bars.
This security element which belongs to the group of pressure limiters must be of such
construction to withstand short-term overdrafts and temperatures and pressure as well as
the content in the liquid glycol for heating.
Usually in the same place the vent (Figure 3) and the pressure gauge are connected so
that these three elements together constitute a security group and can be mounted over T''
connector.
This safety element must be subjected to periodic re-calibration , of which the investor,
i.e. the user of the boiler must have valid documentation.
