For B-type installation, combustion air is taken from the
environment and goes through the openings (shutters) on
the rear panel of the device that must be located in a suita-
ble and ventilated technical room.
9
Read the requirements, instructions and prohibitions de-
tailed below carefully, since non-compliance with them
may be result in a safety hazard or the appliance's malfunc-
tion.
9
Condensation appliances described in this handbook must
be installed with flue gas pipes compliant with applicable
legislation and expressly manufactured for this specific use.
9
Check that pipes and joints are not damaged.
9
Joint seals must be executed with materials that withstand
the condensate's acidity and the temperatures of the appli-
ance's flue gases.
9
When installing flue pipes, always bear in mind the direc-
tion of the flue gases and of possible condensate flows.
9
Inadequate or incorrectly sized flue gas pipes may increase
combustion noise, create condensate extraction issues and
negatively impact on combustion parameters.

Check that pipes are suitably far (min. 500 mm) from flam-
mable or heat-sensitive construction elements.
9
Make sure that condensation is not built up along the duct.
For this purpose, provide a sloping duct of at least 3 degrees
towards the appliance in case there is an a horizontal sec-
tion. If the horizontal or vertical section is longer than 4 me-
ters, a condensate siphon drainage must be provided at the
base of the pipe. The useful height of the siphon must be at
least equal to the value "H" (see figure below). The siphon
discharge must then be connected to the sewerage system
(see paragraph "Preparation for the condensate drain" on
page 26).
0
It is prohibited to block or section the flue gas extraction
pipe or the combustion air suction pipe, if any.
0
It is prohibited to use pipes that not designed for this ap-
plication, because the condensate's action would damage
them quickly.
Maximum equivalent lengths are provided below.
