• Elbows 90° in the horizontal plane:
Horizontal bends are bends which are entirely in the horizontal plane (fig. 12.1,
12.2 and 12.3 I, K and Q).
• Bends 45° or 30° in the horizontal plane:
Horizontal bends are bends which are entirely in the horizontal plane.
• Elbows 90° vertical to horizontal plane:
These are 90° elbows, which proceed from horizontal to vertical
(fig. 12.2 and 12.3 G, O and S).
• Bends 45° or 30 °vertical to horizontal plane:
These are 30° or 45° bends with a vertical offset of less than 45° (fig.12.1 B and D).
• Pipes under a tilt angle:
These are pipes which are vertically ascending at an angle of 30° or 45° (fig. 12.1
C). Fill in only in combination with at least 2x 30 or 45° bends in the vertical part.
• Restrictor table:
See the restrictor table at the right vertical (TVH) and horizontal length (THL).
For "x" and if the values are outside the table, then the combination is not
allowed. Only then adjust the TVH or THL.
If a value is indicated, check that the calculated STL value is not lower than
indicated in the table. In this case STL must be adjusted.
The found value indicates the width of the restrictor ("0" means no restrictor).
Standard is a restrictor of 30mm installed (see fig. 1.5).
When only a vertical flue length is used, than you most install the additional air
restrictor under in the appliance (see fig. 4.1 up to 4.4).
The air restrictor comes standard with the appliance (see fig. 4.0).
