For the Installer

2.2 Installation

2.2.1 Installation room

Basically, any room with normal air humidity and living space temperature in the living area is suitable for instal-
lation, providing it has a flue connection with an adequate draught (see technical data for flue requirements)
and satisfies the statutory regulations and directives.
Note: Due to the operating and flame noises, we do not recommend installing the device in bedrooms or quiet
rooms.
BAXI Bioflo is not allowed to be installed in rooms that are very dusty or humid (e.g. bathrooms, sanitary rooms,
etc.). The combustion air must be free from halogens and hydrocarbons (detergents, e.g. chlorine, ammonia,
fluorine, etc.) otherwise malfunctions may occur.
The installation room should not be too small otherwise the room could be overheated by the heat radiation.
The recommended rule of thumb is: The installation room should account for at least 15% of the area to be
heated.
The boiler must be installed in dry, frost-free premises!
Limits (maximum): Air humidity: 85% at 25° room temperature (noncondensing)
Room temperature +2 to 40°C

2.2.2 Heat radiation

The viewing panel of the BAXI Bioflo means it is inevitable that heat will be radiated into the installation room.
The distribution of heat between air and water heating is approx. 15 : 85 % without the heat shield and approx.
9 : 91 % with the heat shield (.
The following should be noted:
– Heating domestic water in summer:
Heat radiation always heats up the installation room when domestic water is being heated. Although the
amount of radiated heat can be significantly reduced by using the supplied atented heat shield, it can never
be totally prevented.
This means it may not be possible to rule out overheating the installation room on hot days and, above all,
during the summer months.
To remedy this, we recommend heating domestic water using an alternative system such as solar or immer-
sion heater supplementation with indirect cylinder..
– Heating surfaces/radiators in the installation room:
The heat radiation from BAXI Bioflo has been reduced to the minimum necessary, therefore a corresponding
heating surface or radiator should also be installed in the installation room. Heating surfaces in the installa-
tion room are essential when the system is combined with alternative heat generators (solar, accumulator tank
or solid fuel boiler) – Fig. 2.
We recommend using thermostat heads in the installation room.
– Minimum room size:
BAXI Bioflo very rapidly provides the necessary amount of heat at very low building heat demands or in
autumn/spring. Despite the fact that the boiler quickly reduces its output to the minimum level or actually
switches itself off entirely, there will nevertheless be a corresponding amount of heat radiation into the instal-
lation room.
This means it may not be possible to rule out overheating the installation room on hot days and, above all,
during the autumn/spring.
As a remedy, we recommend having an installation room with a minimum size of approx. 15 % of the entire
area to be heated) – Fig. 2.
