•
Clean combustion tubes and reversal chambers.
•
Clean the flue.
•
Check if the flue gate rotates freely.
After cleaning of combustion tubes clean also the ash chamber in boiler’s rear
part (exchanger) through the cleaning flap (11) located at boiler’s side.
6.2. Maintenance
After each heating season clean the boiler thoroughly. Do not drain the water
for the summer season.
However, if the boiler-room is for any reason inactive during winter and there is
risk of frost, drain the water. After cleaning complete the paint coat on the
boiler.
7.0. REPAIR AND OVERHAUL
Minor defects should be removed during current repairs. Periodical overhauls
are made once a year, when the boiler is out of use. For inspection and for
evaluation of the range of repair clean the boiler thoroughly. Overhaul consists
usually in replacement of seals, door screens etc., rarely in replacement of
water grid, which is worn due to furr deposit. After overhaul check tightness of
boiler & heating system. After replacement of side walls and grid or after repair
of breaks and leakage carry out the 0,4 MPa pressure test.
8.0. INDUSTRIAL SAFETY
Operation of the boiler is safe only if the boiler is installed and operated
according to adequate standards and present manual. Especially following
rules should be observed:
•
Fire up the boiler only if the boiler & heating system are filled with sufficient
quantity of water and if inlet and outlet valves are open.
•
To avoid intoxication with carbon monoxide the blow duct in the upper part
should be always opened a little.
•
Observe fire protection rules – keep boiler’s surroundings clean, do not
store inflammable materials near the boiler.
•
Connection to the funnel should be made very carefully, seal all connec-
tions with chamotte clay or graphite cord.
•
If temperatures are low, the heating system is cold and if there is a risk that
the system is frozen behind the boiler do not fire up the boiler before
checking that there is circulation of water in the system.
•
If there is no water in the boiler or in the heating system and the boiler is
filled with glowing fuel
IT IS PROHIBITED!:
•
to fill the system with cold water – risk of boiler’s explosion
•
to extinguish the furnace with water – risk of boiler’s break and
carbon monoxide formation.
