INSTALLATION
6 - FCX/BS HYDRAULIC CONNECTION KIT (OPTION)
The FCX/BS hydraulic connection kit is used for the
hydraulic connection of the boiler to the domestic
hot water production system of the BS type)
(
section 7.4 - page 28 et section 7.6 - page 30 -
chapter IV - INSTALLATION).
Note:
- Installing this kit is mandatory when connecting to
a BS.
Refer to the kit assembly instructions.
If the chosen domestic hot water pro-
duction system is the FCX/ MODULE,
- refer to its technical data sheet.
7 - HYDRAULIC CONNECTION
When the boiler is assembled on an old
installation, make sure that the installa-
tion is rinsed with fresh water, so as to
clear any sediment stagnating in areas
where the flow is slow.
To prevent circulation noises in an ins-
tallation featuring temperature controls,
the following is recommended:
- Do not fit all the radiators with tem-
perature controls,
- Fit a differential valve,
In accordance with the installation stan-
dards, a filling system must be fitted on
the installation.
Never place an isolation valve between
the safety control box and the hot water
tank (FCX + domestic hot water produc
-
tion system) and never between the boi-
ler shell and the expansion vessel.
The boiler should be positioned so that
the connection of the combustion pro
-
ducts outlet system is possible with res-
pect to the heating outlet/return pipes
(
section 3.1 - page 13 - chapter IV - INS-
TALLATION).
- Isolation valves :
It is advisable to place isolation valves on the ins-
tallation outlet and return so that maintenance
can be performed on the boiler without draining
the installation.
- For the FCX boiler + domestic hot water produc-
tion system - See the tank technical instructions.
- Circulating pump :
Set the circulating pump to the speed that is ap-
propriate to the installation’s flow rate and pres-
sure drop (circulation noise reduction, power
consumption optimisation).
- Safety valve:
This must be connected to the used water drain
via a siphon funnel.
- Expansion vessel
If the installation capacity is over 62 litres, an ex-
tra expansion vessel to the boiler expansion ves-
sel will be added.
The correct operation of the boiler requires an
installation pressure of at least 1 bar.
If the installation is a renovation and uses an
open vessel, this must be removed and replaced
with a closed vessel (the boiler is equipped with
one originally) to seal the circuit.
The vessel should be able to support an expan-
sion of 6% of the total water capacity of the hea-
ting circuits. But it is important to note, in order to
guarantee this expansion, that the useful capacity
of a vessel does not equal its actual capacity.
