Clean the surface with some light abrasive material. Put the insulation-sheet in place.
Take the sensor in one hand and put the insulation ring in the sensor. Now place the screw into the ring. Use your index finger to keep the cable facing upwards so you can actually reach the screw.
Take the small flathead screwdriver and carefully move the sensor into place. Never remove the sensor from the cable: bend the cable a bit upwards when mounting.
Fasten the sensor firm but light.
Be careful not to bend the terminals of the temperature-sensor towards the boiler : no connection to the boiler surface is allowed!
