INSTALLATIoN
chImney connectIon
- The chimney connections must comply with the NBN D51-003
standard and in accordance with current regulations.
- Thanks to its built-in gas/air ratio regulator, the
Prestige
is, to
a large extent, independent of pressure drops in the air intake
and flue-gas exhaust systems. However, the maximum pressure
drop of this system may not be exceeded; otherwise, the
pressure would diminish, and in the case of the Prestige 120,
the air pressure switch would lock out the boiler. However, the
gas/air ratio regulator always guarantees optimal combustion
with very low emissions.
- The horizontal flue gas exhaust ducts must be installed with a
sufficient degree of slope towards the boiler: 3° of slope = 5 mm
per meter of duct.
- There must be no obstructions or inlets to other appliances within
a radius of 0.5 meters around the terminal of the
Prestige
.
-
The maximum pressure drop of the chimney is 150 Pascal.
You can calculate this value using the following table:
(please see
sample calculation as well).
- The C33s configuration enables airtight operation in a
pre-existing chimney. The combustion air crosses the space
between the tubing and the pre-existing chimney. Make sure to
clean the pre-existing chimney thoroughly prior to installation,
especially if there is soot or tar residue. Make sure that there
is a clearance area for the combustion air at least equivalent to
the area that would have been provided by separate concentric
ducts or air intake ducts.

Sample calculation
Prestige Solo 50/75:
The diagram below consists of the
following parts: pipe with a moni-
toring s 2 90° pipe bends
+ 2 meters of horizontal pipe +
2 45° pipe bends + (2 + 1 + 1)
meters of vertical and sloped pipe
+ one vertical terminal unit.
The resistance of this system is
as follows:
3 + (2 x 12) + (2 x 6) +
(2 x 5,5) + (4 x 6) + 25 = 99 Pa.
As this value is lower
than the maximum
authorised resistance,
this installation is com-
pliant.
