6.3.1 Screed drying
The combustion chamber must be slowly screed dried as described below when heating
up for the first time to dry out the fireclay.
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:
r
Screed dry the boiler in accordance with the following points:
r
Set the boiler to user level “Service technician” and activate “Baking mode” in the
quick selection menu.
r
Fill combustion chamber with approx. 1/3 of the firewood provided.
r
Ignite firewood and allow to burn away with the combustion chamber door half open.
Once the first load has burned out, add another approx. 1/3 of the firewood provided.
NOTICE! The combustion chamber temperature should continuously rise but must
not exceed 500°C. REMEDY: Only keep the combustion chamber door open a
fraction!
After adding the last batch of firewood:
r
Allow the fire on the grate to burn out.
r
Close the combustion chamber door.
r
Leave the boiler in this state for a few hours (ideally overnight).
The boiler can then be used in accordance with the operating instructions ("Operating the
