Boiler description
Condexa HPR 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;
C93,C93x.
In configuration B23P (when installed indoors), the ap-
pliance cannot 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 requirements for
the installation of the flue, the gas piping and for venti-
lating 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).

WARNING: it is impossible to create modular gener-
ators simultaneously 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
All the appliance functions are electronically controlled
by a board that has been type-approved for safety func-
tions.
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:
− Temperature probes on the delivery and return
lines, to continuously measure the temperature
difference (∆t) between input and output fluid,
and allow the control to intervene.
− Pressure transducer with a minimum pressure
function, to inhibit burner ignition below 0.8 bar.
The following are installed on the combustion circuit:
− Ignition electrode and detection electrode
− Flue gas temperature probe
− Safety thermostat
− Gas valve
− The intervention of the safety devices indicates a
potentially hazardous boiler malfunction, there-
fore immediately contact the Technical Assistance
Service immediately. After a brief pause, it is pos-
sible to try to restart the appliance (see "3.1 Pre-
liminary checks").

Safety devices must be replaced by the Technical
Assistance Centre, using only original parts. Refer
to the spare parts catalogue. After carrying out re-
pairs, check that the appliance is working properly.
The appliance must not be started, not even tem-
porarily, when safety devices are not working or
have been tampered with.
