Modification of the specified operating values will affect the heating
system’s control programme and could lead to malfunctions. Only
trained maintenance and operating personnel may undertake modi-
fications to the operating values.
2.2 Residual risks
Despite all precautions, the following residual risks remain:
For more information on fuel, see chapter “3 Mode of operation”,
section “3.4 Fuel quality requirements”.
Caution!
Hot surfaces
Contact with the hot surfaces of the boiler (e.g. inside doors, flue
pipe, etc.) can result in burns. Even after the boiler is switched off,
the surfaces only cool down slowly.
Wait until the boiler has cooled down before touching non-insu-
lated components.
Danger!
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 has finished burning. Do not leave them open any longer
than necessary and never leave them open unattended.
Warning!
Danger of fire
When the heating system is in operation, open doors and lids con-
stitute a fire hazard. Furthermore, combustion residue (ash, char-
coal etc.) can reignite after being removed from the boiler.
Always keep the doors and lids closed. Only open them when the
boiler has finished burning. Do not leave them open any longer
than necessary and never leave them open unattended. Put the an-
nealed combustion residue in the ash pan of a non-flammable and
closable container.
