4.10 BEFORE COMMISSIONING
To avoid the risk of contamination of dirt and foreign bodies in the
boiler, the entire heating network must be completely fl ushed before
the boiler is connected, then again after the heating circuit has
been heated for the fi rst time and either still hot. This is particularly
important when the boiler is used with an existing heating
installation.
IMPORTANT
:
For optimal performance after installation, this boiler
and its associated heating circuit must be emptied in accordance
with the guidelines given for water treatment in hot water central
heating systems. This involves the use of a heating circuit cleaner.
After cleaning, it is extremely important that all traces of the
cleaning agent are carefully removed from the circuit (abundant
rinsing).
For long-term protection against corrosion and scale, it is
recommended, after washing, to use an inhibitor in accordance with
the recommendations.
If the boiler is installed in a garage or outside, if frost protection
conditions are not guaranteed or if the boiler is left off during the
heating period (holiday home, etc.) in order to provide additional
protection in in the event of a power failure in cold weather, an
antifreeze and a corrosion inhibitor must be combined (MGP
Neutragard type, Sentinelle X500 or equivalent, it must include
inhibitors).
Failure to follow these guidelines will void the warranty.
4.11 END OF THE WORKS
1. Please make sure that the BOILER PASSPORT - report
commissioning the installation supplied with the boiler - is
completely fi lled.
2. Leave a copy for the user
3.Keep a copy.
4. Make sure that the user manual (supplied with the boiler) is given
to the owner or user of the boiler.
5. Inform the user of the operation of the boiler, boiler controls,
heating controls and safety devices.
6. Make sign at the bottom of the last page of the User manual to
validate that the user training has been carried out.
If several heating starts, the use of a primary boiler circulator
associated with a separating bottle is highly recommended add.
4-way hydraulic modules are recommended by GRANT.
Refer to chapter 2.5 for the size and type of the connections and to
chapter 5 for the position of the connections.
4.12 HEATING CIRCUITS WITH
UNDERFLOOR HEATING
In heating circuits with fl oor heating transmitters, it is essential
that the boiler return temperature is maintained above 40 ° C to
avoid internal corrosion of the boiler’s heating body. (see pdf:
REGULATION GRANT 850i4)
4.13 UNDERFLOOR PIPING
If PER BAO or MULTI-LAYER plastic pipes can be used for
underfl oor heating, copper pipes must be used for at least the fi rst
fl ow meter return from the primary piping between the boiler and
the underfl oor mixing valves.
Grant IRL strongly recommends installing a
Grant Mag One magnetic fi lter (or equivalent
*) in the piping of the heating installation. This
must be installed and regularly maintained
in accordance with the fi lter manufacturer’s
instructions.
* As measured by Gauss. The MagOne
magnetic fi lter has a Gauss value of 12000.
The boiler must not be allowed to operate with
return temperatures below 40 ° C when the
heating circuit is in normal operating mode
(after ignition and T ° rise of the boiler with
heating of the circuits)
The fi rst meter of piping connected to both the
boiler heating fl ow / return circuit must be
made of copper on all types of circuits - with
closed vessel or open vessel.
