4.9.1 Emptying ash
Recommendation: Do not remove the ash in the combustion chamber each time you heat
up the boiler, only when the middle row of holes in the cladding plates is no longer visible.
This protects the combustion chamber and makes the heating-up process more efficient.
Carry out all other cleaning work described in the Cleaning section in the same way.
