of potential burns from hot boiler parts and systems. You must never leave unattended children near
boiler that is in operation. During the operation of solid fuel boilers it is prohibited to use any flam

during operation (overheating).
You must not put flammable objects on the boiler and near the
fuel feeding and ash pan openings and ash must be stored in non-flammable containers with a
lid.
When handling fuel and ash, wear protective equipment (gloves, dust mask). Boilers in operation
must be under occasional supervision of the operator. The user may only carry out repair consisting
in simple replacement of a spare part (e.g. a sealing cord, etc.). During the operation check the doors
and cleaning openings for tightness and always tighten them properly. The user must not alter the
structure and electric installation of boilers. The boiler must always be cleaned properly and in time
so that free passage of all the ways can be guaranteed. Cleaning doors must always be properly closed.

any non-standard behavior of the boiler shut down the boiler from operation and call the
service.
