2.2 Residual risk
Despite all precautions, the following residual risks remain:
Caution!
Hot surfaces!
Contact with the hot surfaces of the boiler (e.g. inside doors, flue
pipe, etc.) can lead to burns. Even after deactivation, the surfaces
only cool down slowly.
Wait until the boiler has cooled down before touching uninsulated
components.
Warning!
Danger of asphyxiation due to carbon monoxide!
If the boiler is in operation, carbon monoxide can be emitted
through the open doors or lids.
Always keep the doors and lids closed. Only open them when the
boiler is burnt out. Do not leave them open any longer than
necessary and never leave them open unsupervised.
Warning!
Danger of fire!
When the heating system is in operation, open doors and lids
constitute a fire danger. Also, combustion residues (ash,coal) can
catch fire again after being removed from the boiler.
Always keep the doors and lids closed. Only open them when the
boiler is burnt out. Do not leave them open any longer than
necessary and never leave them open unsupervised. Put the
annealed combustion residues in the ash pan in a non-flammable
and closable container.
Danger!
Danger of explosion
A concentration of carbon monoxide which is too high can lead to
an explosion.
Observed the required conveying pressure of the chimney.
