Filling the condensate drain trap
When the appliance is switched on for the first time, combustion products come out of the con-
densate drain. After a few minutes of operation, check that combustion flue gases are no longer
coming out of the condensate drain; this means that the drain trap has filled to a correct con-
densate height that the flue gases cannot pass through.
Type B open chamber appliances must not be installed in places where commercial, artisan or
industrial activities take place, which use products that may develop volatile vapours or sub-
stances (e.g. acid vapours, glues, paints, solvents, combustibles, etc.), as well as dusts (e.g. dust
deriving from the working of wood, coal fines, cement, etc.). These may be damaging for the
components of the appliance and jeopardise functioning.
In configuration B
and B
, unless local regulations are in force, the appliances must not be

installed in bedrooms, bathrooms, toilets or studios; they must neither be installed in rooms
containing solid fuel heat generators nor in rooms communicating with said rooms.
The installation rooms must be permanently ventilated, in compliance with the local regula-
tions in force (at least 6 cm
for every kW of installed heat input, except in the event of any in-
2
creases needed for electro-mechanical vacuum cleaners or other devices that could put the in-
stallation room under vacuum).
Install the appliances in B
and B
configuration in non-residential premises and which are permanently ventilated.

Failure to comply with the above implies personal responsibility and invalidates the warranty.
