4.4.4 Aligning the boiler block

Fig. 4.7 Aligning boiler block
The boiler block must be level.
Note!
Under no circumstances should there be an
incline to the side of the plug in the upper boss,
otherwise air bubbles could form in the boiler
block.
• Level the boiler block using the adjustable boiler feet
(1, SW 30) on the baseplate at the site of installation.
• Completely connect the boiler to the water supply and
check for leaks at an excess pressure of maximum 6 bar.
Use a calibrated pressure gauge since the mains water
pressure can be considerably higher.
