3 Heating up for the first time
CAUTION
If the boiler heats up too quickly on initial start-up:
If the output during the heating-up process is too great, the combustion chamber may
be damaged as a result of drying out too rapidly!
For this reason the following applies the first time you heat up the boiler:
❒ Start the firewood boiler for the first time in accordance with the heating instruc‐
tions
Heating instructions when starting up a firewood boiler for the first time
❒ Place a piece of wood diagonally across the combustion chamber (see diagram on
left)
➥ Load the boiler with a small amount of firewood (max. 10-20% of the fuel load‐
ing chamber)
➥ Ignite it and allow it to burn slowly with the central pre-heating chamber door
open
NOTICE! Fissures are normal and do not indicate a fault
Once the material in the boiler has burnt down, the boiler can be used in accordance
with the operating instructions ("Operating the system" section).
