Installation on opened central heating system
One of the possible installation processes is shown in Figure 9.
With this system, on the initial line are being set safety distribution line of the expansion
vessel and boiler's valve, and on the initial line of the system are being set boiler's valve, a
pump and a valv. Directly below the open expansion vessel is set short connection between
safety distribution line and safety rebound line, which prevents water freezing on winter in an
expansion vessel.
On safety distribution line and safty rebound line, must not be any kind of fitting. Expansion
vessel must have an overflow pipe as shown on the chart in Figure 9. The volume of the
expansion vessel is calculated by the folloving formula:
V = 0,07xVwater, (l), where Vwater is volume of the water in entire system.
Open expansion vessel is placed vertically above the highest heating body. Under the open
heating system is possible having gravitational heating system.
Note: Installation of the heating system and starting up of the entire system should be
entrusted exclusively to professional service in charge that guarantees the correct operation
of the entire heating system. In case of bad design of the system and possible shortcomings
while installing it by the entity that did the work, complete material responsibility takes the
person to whom was entrusted installation of heating systems, and not a producer,
rappresentative or seller of the boiler.

• When installing the safety valve, please pay attention to the direct connection with water
pipes and sewer, and that valves (faucets) always stay open.
• If using a reinforced hose to connect to the drainage, it must be placed away from the back
side of the cooker.
With first ignition is necessary to examine the the proper functioning of the valve by doing the
following: overheating it up to 100 ° C on short-term basis, examining the proper function of
draft regulator and installing hot water distribution connection up to radiators and directly to
radiators.
