26. Maintenance of the heating system, including boilers
At least once every 2 weeks check or replenish water in the heating system. If the boilers are out
of operation in winter, there is a danger of water freezing in the system and therefore you had better
drain water from the system or fill it with an antifreeze mixture. Otherwise, only drain water in ine-
vitable cases and for the shortest possible time. After the end of the heating season thoroughly clean
the boiler and replace the damaged parts. Do not wait with the replacement of parts until the last
moment; prepare the boiler for the heating system in spring already.
27. Operation and supervision
Boiler operators must always follow the operation and maintenance instructions. Interventions
into boilers that could endanger the health of the operators or other persons in the vicinity are prohibi-
ted. Boilers may only be operated by a person that is more than 18 years old, that has been acquainted
with the instructions and operation of the equipment and that complies with the requirements of § 14
of the Directive no. 24/1984 Coll. You must never leave unattended children near boilers that are in
operation. During the operation of solid fuel boilers it is prohibited to use any flammable liquids for
lighting the fire and it is also prohibited to increase the nominal output of the boiler 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. 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 al-
ter 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.
