Boiler description

1.1
POWER EVO-X is a type C wall-hung condensing boiler that can
operate as follows:
CASE A: heating only, without any external storage tank connected.
The boiler does not supply domestic hot water.
CASE B: heating only, with a thermostatically-controlled external
storage tank (accessory kit available upon request) connected:
in this condition, with every heat request from the storage tank
thermostat, the boiler supplies hot water for the preparation of the
domestic hot water.
CASE C: heating only, with the connection of an external storage
tank (accessory kit available upon request) managed by a
temperature probe, for domestic hot water preparation. Connecting
a boiler that we did not supply, make sure that the probe used has
the following characteristics: 10 kOhm at 25°C, B 3435 ±1%.
Depending on the flue gas exhaust accessory used, the boiler
is classified in categories B23P; B53P; C13,C13x; C33,C33x;
C43,C43x; C53,C53x; C63,C63x; C83,C83x; C93,C93x.
In configuration B23P (when installed indoors), the appliance can-
not be installed in bedrooms, bathrooms, showers or where there
are open fireplaces without a proper air flow. The room where the
boiler is installed must have proper ventilation. Detailed require-
ments for the installation of the flue, the gas piping and for ventilat-
ing the room, can be found in UNI 7129-7131.
This type of appliance can be installed indoors, within a suitable
room (central heating), as well as outdoors, in a partially protected
location (single boiler application).
Furthermore, with the aid of specific accessories, the boiler can be
installed in cascade configuration (up to 4 in-line boilers), or front-
and-back configuration (up to 4 boilers - 2+2).
b
WARNING: it is impossible to create modular generators si-
multaneously containing thermal elements with different heat
input values. Only cascades, with the same thermal element
version on all the thermal modules, can be created.

Safety devices

1.2
All the appliance functions are electronically controlled by a board
that has been type-approved for safety functions.
Any malfunction results in the appliance being shut down and the
automatic closure of the gas valve.
The following are installed on the water circuit:
ƒ Temperature probes on the delivery and return lines, to contin-
uously measure the temperature difference (∆t) between input
and output fluid, and allow the control to intervene.
ƒ Pressure transducer with a minimum pressure function, to inhib-
it burner ignition below 0.8 bar.
The following are installed on the combustion circuit:
ƒ Ignition electrode and detection electrode
ƒ Flue gas temperature probe
ƒ Safety thermostat
ƒ Gas valve
ƒ The intervention of the safety devices indicates a potentially
hazardous boiler malfunction, therefore immediately contact the
Technical Assistance Service immediately. After a brief pause,
it is possible to try to restart the appliance (see "3.1 Preliminary
checks").
b
Safety devices must be replaced by the Technical Assistance
Centre, using only original parts. Refer to the spare parts cat-
alogue. After carrying out repairs, check that the appliance is
working properly.
a
The appliance must not be started, not even temporarily,
when safety devices are not working or have been tampered
with.
b
Tampering, removal, lack of identification labels or anything
else which does not permit the safe identification of the
product, makes any installation and maintenance operation
difficult.
