One of the aspects of installation is shown on fig. 6.
At this system, starting guide is to be installed with safety distribution guide of
expansion vessel and valve of boiler, and on starting guide valve of boiler is to be
installed, as well as pump and valve. Directly below open expansion vessel there
must be short connection of safety distribution guide and safety return guide, which
in winter prevents freezing of water in expansion vessel.
On safety distribution and safety returning guide there may not be any fixture.
Expansion vessel itself must have overflow duct as shown on diagram 7. Volume of
expansion vessel is to be determined by the pattern:
V = 0,07x V water, (l), where V water is water volume and entire power plant.
Open expansion vessel is to be installed vertically above the highest heating body.
At open heating system, gravitaion system of heating is possible.
Note:
Mounting of heating and putting into operation of entire system should be
exclusively carried out by expert who guarantees proper work of entire heating
system. In case of weakly designed system and eventual omissions upon works by
mentioned person, complete material responsibility shall be borne exclusively by
person who carreid out installation of heating system,not manufacturer,
representative or retailer of the boiler.
Important
• Installation of cooker should be carried out by expert according to appropriate
project design. Cooker construction enables connection to open or closed heating
system. All connections must be well sealed and tightened. Prior to operation,
complete installation should be inspected with water under pressure of 3 bar.
• upon installation of safety valve, pay attention to direct connection with aqueduct
and sewage, and if valves (taps) are always open.
• If reinforced hose is used for connection with drainage opening, it must be removed
from back side of cooker.
At the first firing up,
it is necessary to inspect accuracy of valve by short-term
overheating up to 100°C, and then inspect accuracy of air flow regulator and
installation for distribution of hot water to radiators, as well as radiators themselves.
