INSTALLATION
CONNECTION TO THE CHIMNEY
- The chimney connections must comply with the applicable
standards (in Belgium: NBN D51-003), the local energy
supplier’s instructions, the fire regulation and neighbourhood
good practices.
- The Prestige has an in built gas/air ratio regulator, which makes
it largely independent of the pressure drop in the air intake and
flue gas extraction system. However, the maximum pressure
drop for this system may not be exceeded, or the pressure will
diminish. Nevertheless, the gas/air ratio regulator continuously
guarantees optimum combustion with very low emission levels.
- The horizontal flue gas pipes must always be installed with a
min. slope of 5 mm per meter, upwards from the boiler side.
- There must be no obstruction or openings for any other
appliances within a radius of 0.5 metres around the flue
terminal of the
Prestige .
- The maximum flue resistance is 150 Pascal. You can use the
following table as the basis for calculating this value
(please also
refer to the specimen calculation presented under the table).

Sample calculation:
The diagram below consists
of the following parts: pipe with
monitoring s 2 * 90°
pipe bends + 2 metres of
horizontal pipe + 2 * 45° pipe
bends + (2 + 1 + 1) metres of
vertical pipe and fall back +
discharge.
Therefore, 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.
This value is less
than the maximum
authorised resistance,
therefore the
installation is
compliant.
