NOTE
Pay particular attention to maintain the roundness of the connection stub pipe when filling the gap with
mortar. Possible surfaces which are not round will make it impossible to set the valve.
Set the prepared valve in the connection stub pipe. If it's possible to access the space between the nozzle and the
stub pipe wall, it should be packed with mineral wool (fig. 10).
