Warning and Safety instructions
~
In order to function correctly, the oven requires an adequate
supply of cool air. Ensure that the supply of cool air is not impaired
(e.g. by heat insulation strips in the housing unit). Please also ensure
that the cool air supply is not unduly heated by other heat sources
such as a solid fuel stove.
~
If the oven is installed behind a furniture panel (e.g. a door),
ensure that the door is never closed whilst the oven is in use. Heat
and moisture can build up behind a closed furniture panel and
cause subsequent damage to the oven, the housing unit and the
floor. Do not close the door until the oven has cooled down
completely.
