Filling the condensate drain trap
On rst lighting of the boiler, ue gas
may come out the condensate drain; aer
a few minutes’ operation check that this
no longer occurs. If this is the case, the
drain trap is correctly lled with conden-
sate up to a height that does not allow the
ue gas to pass.
Type B open chamber boilers must not be
installed in places where commercial, ar-
tisan or industrial activities take place,
which use products that may develop vo-
latile vapours or substances (e.g. acid va-
pours, glues, paints, solvents, combusti-
bles, etc.), as well as dusts (e.g. dust
deriving from the working of wood, coal
nes, cement, etc.), which may be dama-
ging for the components of the appliance
and jeopardise functioning.
In conguration B22 and B52, unless lo-
cal regulations are in force, boilers must
not be installed in bedrooms, bathro-
oms, toilets or studios; ey must neither
be installed in rooms containing solid
fuel heat generators nor in rooms com-
municating with said rooms.
e installation rooms must be perma-
nently ventilated, in compliance with the
local regulations in force (at least 6 cm²
for every kW of installed heat input,
except in the event of any increases nee-
ded for electro-mechanical vacuum clea-
ners or other devices that could put the
installation room under vacuum).
Install the appliances in B22 and B52 conguration is
only recommended in places that are not lived in and
which are permanently ventilated.
Failure to comply with the above implies
personal responsibility and invalidates
the warranty.
