Residual Risks - HDG Euro 30 Operation Manual

2 Safety notes – Residual risks
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
modifications to the operating values.
For more information on fuel, see chapter "3 Mode of operation",
section "3.4 Fuel quality requirements".

2.2 Residual risks

Despite all precautions, the following residual risks remain:
Caution!
Hot surfaces
Contact with the hot surfaces of the boiler (such as the flue gas
pipe) 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-
insulated 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
constitute a fire hazard. Furthermore, combustion residue (ash,
charcoal 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
annealed combustion residue in the ash pan of a non-flammable
and closable container.
