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:
2.5 + (2 x 6.0) + (2 x 5.0) +
(2 x 4.0) + (4 x 5.0) + 20
= 72.5 Pa.
This value is less
than the maximum
authorised resistance,
therefore the
installation is
compliant.
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
HeatMaster
®
TC
has an inbuilt 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.
- To avoid any condensate flow through the terminal, 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
HeatMaster
®
TC
.
-
The maximum flue resistance is 130 Pascal for the
HeatMaster
®
35 TC and 150 Pascal for the HeatMaster
®
85
TC.
