A  Maximum supportable height above Tee piece when chimney is supported by wall support at base�
B  Maximum supportable height that can be borne by wall support�
C  Maximum distance between lateral supports i�e� wall bands and wall supports�
D  Maximum allowable free standing height above last support�
-   For non-vertical parts of flue system the maximum distance between two wall bands i�e� brackets is 2,5* m (*ø 450-600 = 3,5 m)
-  In case of a condensing application a slope of 3° upwards, starting from the appliance, has to be applied
Important: the product with the lowest load bearing capacity determines the maximum supported height�
The clearance to combustible materials, as indicated in the CE-designation, applies to flues with a nominal diameter up to and 
including 300 mm� Regarding flues with a larger nominal diameter, the clearance must be multiplied by a factor: ø 350 - ø 450 x 1�5, 
ø 500 - ø 600 x 2, > ø 700 x 4�
