Data for sizing type C air/fumes installation pipes.
Examples of the two principal type C configurations:
▶
C13 - using a concentric DN60/100 90°C curve, the maximum permitted extension with concentric DN60/100 straight pipe sec-
tions is 5.75 m, while the minimum permitted extensions is 0.75 m.
▶
C33 - the maximum permitted extension with concentric DN60/100 straight pipe sections is 6.25 m.
Exhaust pipes exposed to atmospheric agents must be made of black polypropylene or an equivalent weather resistant
material. For sizing, refer to the established regulations and the manufacturer’s instructions.
The following table gives a brief description of the possible installation configurations.
Table 5�6 – Installation configuration (types B and C)
TYPE
CONFIGURATION
B23P
The combustion products are exhausted outside, from the wall or roof, while the combustion air is drawn directly from the room in which the appliance is
installed. This configuration can ONLY be installed in open areas or areas sufficiently well ventilated and free of combustible powders.
B33
Evacuation of combusted gas into the flue, combustion air drawn directly from the room in which the appliance is installed. This configuration can ONLY be
installed in open areas or areas sufficiently well ventilated and free of combustible powders.
B53P
Boiler designed for connection, via its own pipe, to a dedicated combustion product evacuation terminal. The air is drawn from the installation room and the
combustion products are evacuated outside the room. This configuration can ONLY be installed in open areas or areas sufficiently well ventilated and free of
combustible powders.
C13
Type C boiler connected, via its own pipes, to a terminal installed horizontally on the wall or roof. The outlets of the pipes are concentric or sufficiently close to
each other to be exposed to analogous wind conditions.
C33
Type C boiler connected, with its pipes, to a vertical terminal. The outlets of the pipes are concentric or sufficiently close to each other to be exposed to
analogous wind conditions.
C43
Type C boiler connected, via its pipes and optionally with a fitting, to a collective piping system composed of a pipe for combustion air supply and a pipe for
combustion product evacuation. The outlets of the system of collective pipes are concentric or sufficiently close to each other to be exposed to analogous
wind conditions.
C53
Type C boiler connected, via its separate pipes, to two terminals which can be installed in zones at different pressures.
C63
Type C boiler designed for connection to a system for combustion air supply and combustion product evacuation which is approved and sold separately.
C83
Type C boiler connected, via its pipes, and optionally via a fitting, to an air supply terminal and connected to a dedicated or collective flue.

PROGRAMMING OF HYDRAULIC PARAMETERS
The hydraulic parameters can be set according to the procedure described in this paragraph only when the appliance is not
connected to a DDC.
If the appliance is connected to a DDC, follow the instructions given in the DDC manuals exclusively.
To configure the hydraulic parameters, access menu 3 of the controller.
For the use of the controller, refer to procedure "HOW TO ACCESS THE MENUS" in Paragraph 4.2

14.
Table 5.7

29 gives the three parameters used for hydraulic configuration.

Description of parameters
▶
Hot water
thermostat control: parameter "160". This parameter takes two values: "0" and "1". Value "0" indicates that the appli-
ance's "activation/deactivation" temperature is to be read by the water probe at the appliance’s INTAKE. Value "1" indicates that
the appliance’s "activation/deactivation" temperature is to be read by the water probe at the appliance’s OUTLET.
