high water temperature and pressure,
and be
conveyed to the sewer drain
.

Suggestions for use
If heat stove installation calls for interaction with
another pre-existing system including a heating
appliance (gas boiler, methane boiler, oil fi red
boiler etc.) contact qualifi ed personnel who
may then be responsible for system conformity,
according to the provisions of applicable laws.
System washing
In compliance with standard UNI-CTI 8065
and to protect the heating system from harmful
corrosion, scaling or deposits, it is very important
to wash the entire system before connecting
the heat stove in order to remove residues and
deposits.
After washing the system it is recommended to
use inhibitors to protect it against corrosion and
deposits.
Always install shutoff valves upstream of the boiler,
in order to isolate it from the water system, should
it be necessary to move it in order to perform
routine and/or extraordinary maintenance.
These are all the more useful on the system fl ow
and return piping if the heating system is on a
higher fl oor than the boiler.
The pressure discharge pipe must provisionally
be connected to a jug or funnel to prevent water
from leaking and wet the structure and fl oor in the
event of overpressure.
