Installation
The valve should be installed high on the wall, preferably close to a heat source.
1.
Hole making
The fall outwards should be around 1°.
For Ø100 and Ø125 it is recommended to use a hole making tool to obtain clean edges (Fig. 1 page 21). For Ø160
and sound absorption valves it is recommended to use a compass saw on account of the high torque in the drill
(Fig. 2 page 21).
Recommended hole dimensions in accordance with the table:

** It is possible to install the valve without cover plates but the holes must then be made very precisely.
