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. Pay attention also to the information in the operating instruc-
tions for your Comfort ventilation system.
䡲 When carrying out maintenance work on the appliance, including replacing
light bulbs, 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.
