F CALCULATION TABLE FLUE GAS REDUCTION
The calculation table shows when you need to place a flue gas
ristrictor
Result Action
√ No ristrictor required
R Position the resitrictor
X No good operation guaranteed *
F.1 Horizontal terminal flue diameter F.2 Vertical terminal flue diameter 200/130
For a vertical terminal the minimal starting length is 0,5 meter
and the minimal vertical section is 1 meter.
* Perhaps the powerfan is a good solution here.
