1.13 INSTALLATION OF BOILER TYPE B
WITH OPEN CHAMBER AND FAN
ASSISTED (OPTIONAL).
In this configuration the relevant terminal must
be used (present in the relevant intake kit for
the installation in question) to be placed on
the intake hole above the sealed chamber (Fig.
1-10). Air intake takes place directly from the
environment and flue exhaust in individual flue
or to the outside. The boiler in this configuration,
following the assembly instructions stated on the
relative instruction sheet, is classified as type B
23
or B
53
(according to the applicable regulations).
With this configuration:
air intake takes place directly from the environ-
ment in which the boiler is installed and only
functions in permanently ventilated rooms
- the flue gas exhaust must be connected to its
own individual flue or ducted directly into the
external atmosphere;
- Type B open chamber boilers must not be
installed in places where commercial, artisan
or industrial activities take place, which use
products that may develop volatile vapours
or substances (e.g. acid vapours, glues, paints,
solvents, combustibles, etc.), as well as dusts
(e.g. dust deriving from the processing of
wood, coal dust, cement, etc.), which may be
harmful for the components of the appliance
and jeopardise operation;
- in B
23
and B
53
configuration, the boilers must
not be installed in bedrooms, bathrooms or in
studio flats;
- installation of appliances in B
23
or B
53
configura-
tion is recommended in non-residential prem-
ises and which are permanently ventilated.
The technical regulations in force must be
respected.
Max. length of exhaust duct.
The flue pipe (both
vertical or horizontal) can be extended to a max.
length of 30 linear metres
.
