boilers can also be
installed in B23 open configurations using suitable
piping in compliance with applicable laws and stan-
dards.
b
Even if the flue pipes pass through combustible
walls, it is not necessary to respect a minimum
installation distance (between the flue and the
walls), since flue gas temperature is below the
maximum permitted temperature for the flue pipes
(according to EN 15035). You should nevertheless
always respect the specifications given in the tech-
nical data sheets for the materials used in the walls.

boilers derive their
comburent air from the room in which they are installed.
Suitable air vents must therefore be provided in com-
pliance with applicable laws and standards.
a
Never obstruct or restrict the air vents in the room
where the appliance is installed.
