Pre-heating the oven
It is only necessary to pre-heat the oven
in a few instances.
Most dishes can be placed in a cold
oven. They will then make use of the
heat produced during the heating-up
phase.
If the recipe requires pre-heating, place
the food in the oven once the
temperature indicator light goes out.
Pre-heat the oven when cooking the
following food with the following oven
functions:
Fan Plus 
– dark bread doughs
– beef sirloin joints and fillets
Conventional Heat 
– cakes or biscuits with a short baking
time (up to 30 minutes)
– delicate mixtures (e.g. sponges)
– dark bread doughs
– beef sirloin joints and fillets
Rapid Heat-up

phase can be shortened.
Do not use Rapid Heat-up  to
pre-heat the oven when baking
pizzas or delicate mixtures (e.g. small
baked goods with a high sugar
content, pizza, choux pastries,
sponges).
Otherwise they will brown too quickly
from the top.
