Plumbing system connection
The connection of the stove to the
plumbing system must be made ONLY by
specialized personnel who are capable of
carrying out installation properly, in compliance
with current standards in the country of installation.
The manufacturer will not be held responsible for
damage to persons or things in the event of failed
operation if the aforementioned warning is not
complied with.
There are 2 different types of systems:
- Closed vessel system
- Open vessel system.
Closed vessel system
This product has been designed and built to work with
closed vessel systems. In general, the closed vessel
system has the following expansion as the expansion
vessel pre-loaded. In addition to the expansion device,
the closed vessel system must be provided in accordance
with current Italian UNI 10412-2 (2009) by:
•
safety valve
•
thermostat control of the circulator
•
device alarm sounds
•
temperature Indicator
•
pressure indicator
•
audio alarm
•
automatic adjustment
•
safety thermostat with manual reset
•
circulation system
Open vessel system
The open vessel system is a more secure system that
does not require the addition of further securities.
The fireplace stoves, wood boilers and stoves necessarily
require use of an open vessel system.
A plant run open vessel, connected to a thermoproduct,
may provide for circulator mounted on the return, in this
way the system would work at lower temperatures to the
advantage of a longer life.
While working under optimal conditions, the pump
mounted on the back can push the water through the tube
pan on safety and can make it back in the system through
the inlet pipe causing a phenomenon of oxygen that is
highly damaging to life of the boiler.
To prevent this phenomenon, it is possible to apply the
following
measures:
•
lower the speed of the pump so as to reduce the
prevalence
•
hold, if possible, the tray a little lower and raise the
maximum allowed the safety tube
•
perform the separation between the safety pipe and the
discharge pipe, not at an angle of 90 ° but with a curved
connection.
