WARNING: Risk of injury from inadequately secured

the boiler sections safely.
The boiler block is always installed starting from the rear with the rear
section (Fig. 7, [4]) and working towards the front. The front section
(Fig. 7, [10]) is always fitted last.
Observe the directional arrows (Fig. 7, [9]) during assembly and carry
