Cleaning the system and characteristics of
In the case of a new installation or replacement of the boiler, it is nec-
essary to clean the heating system. To ensure the device works well,
top up the additives and/or chemical treatments (e.g. anti-freeze liquids,
values indicated.

The boiler must be connected to a heating system and a DHW network
both sized according to its performance and output.
Before installation, wash all system piping carefully in order to remove
any residues that may impair the operation of the appliance.
Under the safety valve, install a water collecting funnel with the
corresponding discharge in the event of leaks due to the overpressure
of the heating system. The domestic hot water circuit does not need a
safety valve, but make sure that the pressure of waterworks does not
exceed 6 bar. In case of doubts, install a pressure reducer.

This type C condensing boiler is designed for heating and DHW produc-
tion and, depending on the type of installation, falls into two categories:
1.
pipe and combustion air intake from the installation area. If the boiler
is not installed outdoors, an air intake point in the installation area is
compulsory;
2. type boiler C(10)3; C13,C13x; C33,C33x; C43,C43x; C53,C53x;

ANTI-FREEZE SYSTEM
The boiler comes as standard with an automatic anti-freeze system,
which activates when the temperature of the primary circuit water
drops below 5°C. This system is always active and provides protec-
tion for the boiler up to an air temperature in the installation area of
>0°C.
b
To take advantage of this protection (based on burner opera-
tion), the boiler must be able to switch itself on; any lockout
condition (e.g. a lack of gas or electricity, or the intervention of a
safety device) therefore deactivates the protection.
If the machine is left without power for long periods in areas where tem-
peratures may fall below >0°C, and you do not want to drain the heating
system, you are advised to add a good quality anti-freeze liquid to the
primary circuit to protect the machine from any risk of freezing. Carefully
follow the manufacturer's instructions with regards not only the percent-
age of anti-freeze liquid to be used for the minimum temperature at which
you want to keep the machine circuit, but also the duration and disposal
of the liquid itself.
For the DHW part, we recommend you drain the circuit.
The boiler components are made of materials resistant to antifreeze liq-
uids containing ethylene glycol.
-
When the boiler is installed in a place where there is a danger of frost, with
outdoor air temperatures below >0°C, an anti-freeze heater kit - available
on request - must be used to protect the sanitary circuit and condensate
drain (see catalogue price list), which protects the boiler down to -15°C.
b
The assembly of the antifreeze heater kit must only be carried out
by authorized personnel, following the instructions contained in the
packaging of the kit.
MINIMUM CLEARANCES
Access the inside of the boiler for routine maintenance tasks, respecting
the minimum installation clearances.
When positioning the appliance, bear in mind that:
- it must be installed on a wall that can support its weight
- it must not be placed above a cooker or other cooking device;
-
er is installed.
