… Safety precautions

䡲 If another appliance – fuelled by gas or other fuels – is being used at the
same time, ensure that there is a sufficient supply of fresh air. This does
not apply to air recirculation units.
䡲
With the simultaneous operation of firing (e.g. wood, gas, oil or coal-fired
heating systems), safe operation is only possible providing a room nega-
tive pressure of 4 Pa (0.04 mbar) is not exceeded at the location of the ap-
pliance. Risk of toxic fumes! An adequate flow of fresh air must be
guaranteed, e.g. via non-closable openings in doors and windows and
combined with ventilation wall bricks for incoming and exhaust air or by
other technical means.
䡲
When carrying out maintenance work on the appliance, including replacing
the light bulb, cut off the electricity supply to the appliance (remove the
screw fuse from the holder or switch the circuit breaker off, or disconnect
from the mains supply).
䡲 When cleaning the appliance make sure no water gets inside the appli-
ance. Use a moderately damp cloth. Do not spray the inside or outside of
the appliance with water. Do not use a steam cleaner. If water gets inside
the appliance, it can cause damage.
