by at least 300 mm before the opening - at the other sides by at least 100 mm. As non-flammable, heat
insulation pads you can use all materials of the A flammability class.

flooring (Industrial, Super)
C3- high flammability
Fibreboard panels (Hobra, Sololak, Sololit), cellulose materials,
polyurethane, polystyrene, polyethylene, lightened PVC
WARNING - In circumstances leading to the danger of transient ingress of flammable gases
or vapours and during work that might result in a temporary risk of a fire or explosion (e.g.
gluing of linoleum, PVC, etc.) the boilers must be put out of operation in time before the
occurrence of the danger. No objects of flammable substances may be put on the burner
and boiler in a smaller distance than the safe distance from them (more - see ČSN EN
13501-1).
11. Connection of boilers to the electric mains
The boilers are connected to 230 V, 50 Hz mains with a mains cable without a plug. The mains
supply cable is of the M type and in case of repair it must be replaced with the same type by the ser-
vicing organization. Boilers must be connected to the mains by a qualified person in accordance with
valid regulations of the particular country.
CAUTION - The mains cable must not be equipped with a plug (designed to be connected
to a socket). It must be connected in a fixed way to a switchboard or junction box to avoid
confusion of the conductors.
