Requirements For Proper Installation; Eliminating The Air From The Heating Circuit And Boiler; Cleaning The System / Characteristics Of The Heating Circuit Water - Beretta POWER X 35 Manual Del Instalador

Frost protection
The electronic devices that manage the heating unit come
with an anti-freeze function. When the delivery temperature
drops below a certain minimum value, the burners are acti-
vated at the minimum power level, based on the operating
parameters.
b
In order for the anti-freeze system to function prop-
erly, however, the electrical power and gas supplies
must be present, and the water circuit must be prop-
erly pressurized.
If deemed necessary by the designer, glycol can be added
to the circuit (up to a maximum of 50%), keeping in mind
that this will result in significant losses in efficiency, as it
alters the specific heat of the fluid itself.
Furthermore several parts of the system could be dam-
aged by altering the pH.
3 2 Requirements for proper
installation
The POWER X boiler's particular characteristics guarantee
significant advantages during both the installation and op-
erating phases, provided that certain measures are taken
beforehand.
In order to facilitate the entire installation procedure and
avoid the need for future changes or adjustments, the fol-
lowing pages illustrate all the recommendations to be re-
spected for the POWER X boiler's proper installation, which
must be carried out by a professional installer, in order to
ensure the user's complete satisfaction.
System cleaning
This preventive measure is rendered absolutely necessary
when replacing a heat generator on a pre-existing system,
but is nevertheless also recommended to be performed on
new systems in order to remove any waste, impurities, pro-
cessing residues, etc.
To clean the system, if the old generator is still present in
the system:
- add a descaling additive (e.g. FERNOX Superfloc) to
the system's water;
- Have the system operate with the generator ON for
approximately 7 days;
- Discharge the system's dirty water and wash the sys-
tem once or several times using clean water.
- If the system is very dirty, repeat the last procedure
one more time.
If the old generator is not present or not available, use a
pump to circulate the water with the additive within the sys-
tem for approximately 10 days, and then perform the final
washing procedure, as described under the previous point.
Once the cleaning operation has been completed, it is rec-
ommended to add a protective liquid (e.g. FERNOX MB-1)
to the system's water before installing the boiler.
The warranty slip endorsed during the course of commis-
sioning will have to be produced for any servicing required
during the guarantee period. The manufacturer shall not
be held liable for any damages caused by mishandling,
improper use or errors in installation, use and maintenance
work on the appliance. In the event of breakdown or mal-
function switch off the appliance, avoiding to make any
attempt to repair it and contact the Technical Assistance
Centre.
3 3 Eliminating the air from the
heating circuit and boiler
During the initial installation phase, or in the event of ex-
traordinary maintenance, you are advised to perform the
following sequence of operations:
1 Use a CH11 spanner to open the air vent valve (A) lo-
cated on the delivery pipe. Connect the tube (supplied
with the boiler) to the valve, so the water can be drained
into an external container.
2 Open the valve to fill the system, and wait until water
begins to seep out of the valve.
3 Switch on the electricity supply to the boiler, leaving the
gas valve closed.
4 Activate a heat request via the ambient thermostat or
the remote control panel, so that the 3-way valve goes
into heating mode.
5 Activate a hot water request using the storage tank's
thermostat.
In the case of a cascade configuration, activate a heat
request from the control unit.
6 Carry on with the sequence until only water comes out
of the air vent valve, and the air flow has stopped. Close
the air vent valve.
7 Check the system pressure level is correct (the ideal
level is 2 bar).
8 Close the system filling valve.
9 Open the gas valve and ignite the boiler.
3 4 Cleaning the system /
characteristics of the heating
circuit water
In the case of a new installation or replacement of the boil-
er, it is necessary to clean the heating system.
It is recommended to equip the system with a filter for col-
lecting and separating any impurities that may be present
within the system itself (sludge remover filter)
To ensure the device works well, top up the additives and/
or chemical treatments (e.g. anti-freeze liquids, filming
agents, etc.) and check the parameters in the table are
within the values indicated.
