Caution – risk of poisoning.
Isolate the appliance from the power supply prior to changing a
fuse. The mains terminals are 'live' even when the appliance is in
standby mode (OFF).
Caution – risk of electrocution.
The use of antifreeze is not permissible.
The control unit protects the gas condensing boiler against frost.
The risk of frost cannot be totally prevented, e.g. during longer
power failures. Therefore install the gas condensing boiler only
in rooms that are free from the risk of frost. Should there be a
risk of frost during longer idle periods when the heating system is
switched off, ask your local heating contractor to drain the condens-
ing boiler and the heating system to prevent pipes from bursting.
Caution – risk of water damage and faulty operation
due to freezing.
With low outside temperatures, the water vapour contained in the
flue gas may condense on the balanced flue and freeze. This ice
may fall from the roof, causing personal injury or material
losses. Prevent ice from falling by taking on-site measures, e.g.
installing a snow guard.
Caution – risk of injury.
