(The maximum length corresponds to the total length from the appliance to the ue terminal)
Thecalculationwasmadetakingthepressureconditionsintoaccount(geodeticheight:325m).Thespeciedlengthsrefer
toconcentricbalanceduesandstandardues,andapplytooriginalWOLFcomponentsonly.
Where necessary, adapt the installation examples to the relevant building regulations and requirements in your country/region. Discuss any
questions relating to the installation, particularly regarding the inspection components and ventilation apertures, prior to installation with your
local ue gas inspector.
Note
Calculatingthebalanceduelength
The calculated length of the balanced ue or standard
ue is derived from the straight pipe length and the length
equivalent of any pipe bends.
Example:
Length of straight balanced ue 5.5 m
87° support bend = 2.0 m
2 x 45° bends = 2 x 1.2 m
L = 5.5 m + 1 x 2.0 m + 2 x 1.2 m
L = 9.9 m
Bend Type Calculatedlength[m]
30° Single wall 0,4
45° Single wall 0,6
87° Single wall 1,0
30° Concentric 0,7
45° Concentric 1,2
87° Concentric 2,0
