Boiler should be connected by hot and return water pipes not
smaller than 1.5’’ in diameter
•
Boiler may be connected to the heating system with the expansion
tank, where operating pressure does not exceed 0,15 MPa (1,5
kgf/cm2);
•
If system pipes have valves, that disconnect boiler from the
system, mounted, they have to be fully opened. To avoid break
down due to inadvertence, valve handles should be removed.
•
It is necessary to mount the protection valve that keeps the
operating pressure in the system not greater than 0,15 MPa (1,5
kgf/cm2).
Notice:
To avoid appearance of the condensate, which may shorten
the service time of the boiler several times, 3-way valve,
controlled by the AKR controller should be mounted in the
system. That enables keeping the return water temperature
not lower than 60 degrees.
