3.2.5. Ventilation of the premises
The sealed room condensing boilers does not pollute the environment in which is installed, therefore, it does not require any special rec-
ommendation on ventilation spouts as regards air combustion; same applies to the room where it is to be installed.
The boiler must be installed in an appropriate room, in accordance with UNI 7129 and UNI 7131, herein fully
applied.
3.2.6. Air suction / fumes exhaust system
As regards fumes emission into the atmosphere and the air suction / fumes exhaust systems, follow the laws and regulations in force,
herein integrally applied.
On the boiler are installed safety devices for the combustion products evacuation control.
In the event of air suction / fumes exhaust system, these devices set the boiler in safety and the LCD display
shows the flashing code E14.
It is strictly forbidden to tamper with and/or to remove these safety devices.
In the event of repeated shut-downs of the boiler, check the air suction / fumes exhaust pipes inlet, which
might be obstructed or inappropriate for fumes discharging into the atmosphere.
For the air suction / fumes exhaust system must be used the original pipes and specific systems for conden-
sation boilers envisaged by the manufacturer, resistant to the corrosion caused by the acids in the conden-
sate.
The drain pipes must be installed with a slope toward the boiler so as to ensure the reflux of the condensate
toward the combustion chamber, which is designed to collect and discharge the condensate.
In case doing so it is not possible, install, at the condensate stagnation points, systems able to collect and
convey the condensate toward the draining system.
Avoid condensation stagnation points inside the combustion products evacuation system, except for the liq-
uid head of the possible siphon connected to the combustion products evacuation system.
The manufacturer declines any liability for damages caused by wrong installation, use, processing of the appliance or failure to
comply with the instructions provided by the manufacturer or by the standards in force on the installation of such appliances.
