If boilers are located on a floor of flammable materials, they must be installed on a non-flammable,
heat-insulating pad, exceeding the ground plan at the side of the feeding and ashpan opening 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.
Tab. 1
Flammability classes of build-
ing materials and products
A - no flammability
granite, sandstone, concrete, brick, ceramic tiles, mortar, fire-resist
-
ant plastering, etc.
B - difficult flammability
Akumin, Izomin, cemented fibreboard, Lignos, panels of basalt felt,
fibreglass panels, Novodur
C1- poor flammability
hardwood (oak, beech), hardboard panels, plywood, Sirkolit, Wer-
zalit, hardened paper (Formica, Ecrona)
C2- medium flammability
softwood (pine, larch, spruce), chipboard and cork panels, rubber
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 in case of repair it must be replaced with the same type by the servicing organization.
Connection, maintenance and reparation can be made only 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.
Mains cable must be regularly checked and maintained in the prescribed condition. It is forbidden
to interfere in to the safety circuits and elements for safe and reliable operation of the boiler. If any
damage of electrical equipment must be the boiler out of operation, disconnect from the mains and
ensure a qualified repair according to applicable standards and regulations.
