Ensure that the hydraulic pressure measured after the reduction valve on the supply pipe does not exceed
the operating
pressure specified on the rating plate of the component
(boiler, heater etc.).
As the water contained in the heating system increases in pressure during operation, ensure that its
maximum value does not exceed the maximum hydraulic pressure specified on the component rating
plate.
Ensure that the safety valve outlets of the boiler and hot water tank, if any, have been connected to drain
in order to prevent the valves from
flooding the room
if they open
.
Ensure that the pipes of the water and heating system
are not used as an earth connection
for the
electrical system as this can seriously and very rapidly damage the pipes, boiler, heater and radiators.
Once the heating system has been filled, you are advised to close the supply cock and keep it closed so
that
any leaks from the system
will be identified by a drop in hydraulic pressure indicated on the system
pressure gauge.
IMPORTANT!
If the boiler is not supplied with acid condense neutralizer, a siphon must be fitted on
the condensate drain in order to avoid flue gas leakage.
NOTE: IF ONLY ONE RETURN IS REQUIRED, ALWAYS USE THE LOW TEMPERATURE ONE
