Caution!
Hot surfaces
Contact with the hot surfaces of the boiler can lead to burns.
Wait until the boiler has cooled down before touching non-insu-
lated components.
Danger!
Danger of asphyxiation and explosion from carbon monoxide
When the boiler is in operation, carbon monoxide escaping from
open cleaning or inspection hatches can cause asphyxiation or ex-
plosions.
Do not leave these open any longer than necessary.
Warning!
Danger of fire
Opening doors and lids to hot combustion residues can pose the
danger of fires.
Keep the openings closed during operation, and when performing
cleaning work, allow the combustion residues to cool down before
you place them in a fireproof container.
Warning!
Danger from suspended loads
The boiler weighs over 700 kg. If the boiler is dropped during trans-
port, persons can be seriously injured and the boiler can be dam-
aged.
Make sure that you use appropriate lifting gear when placing the
boiler.
