Safety of life and property
In practice, situations may occur
in which the users must apply
necessary precautions:
• Preventing the boiler from switching on
(also accidental) when inspecting the
chimney, flue-gas duct, water and gas
piping – i.e., electricity supply to the boiler
must be stopped (e.g., by unplugging) in
addition to using the boiler switch;
• Stopping the boiler whenever flammable
or explosive vapours appear (even if
temporarily) – such as vapours of flooring
glue, paints when surface finishing, gas
leaks, etc.);
• If it is necessary to discharge water
from the heating system, it must not be
dangerously hot;
• If water has leaked from the boiler
exchanger, or if the exchanger is filled
with ice, no attempts to start the boiler
should be made until normal operating
conditions prevail.
• If there is a (whether confirmed or
suspected) gas leak or stoppage in the gas
supply, switching off the boiler, shutting
down the gas supply and calling gasworks
or a specialised service centre
