– current elimination of minor operational problems on all the installed units (for
instance, replacement of a safety fuse in the controller, cleanup of the screw feeder, fixing of
a seal "burner – boiler", cleaning of the holes forcing the air into the burner);
– carrying out of all the current activities associated with maintaining the proper
operation of the burner;
– ongoing monitoring of the controller operation as well as operation of the
measuring-and-
recording equipment.
4.3.1. Periodic Technical Maintenance
In addition to current activity, it is the user’s responsibility to perform all periodic
technical inspections of the boiler, the burner, the screw feeder, the bunker, the installed
units and the chimney.
Inspection of the boiler and the fume extraction plant shall be carried out in
accordance with the schedule
presented in the technical documentation for the boiler.
Within the framework of the periodic technical inspections it is required to perform
:
–
Monthly maintenance.
Clean the burner outlet chamber from dirt and clean the air
intake openings.
Monitor the controller operation
.
Check connections of the tank, screw
feeder,
and the burner. In
case of loose connection,
it is required to tighten.
–
Quarterly maintenance
.
Clean the internal space of the blower fans of the burner
with a vacuum cleaner
.
Check the fastening of the burner to the boiler, and in case of
detecting loose
connection, it is required to tighten. Clean
the heating elements of the
ignition
system. Check, clean, and tighten the sensor connections.
Check the fastening of
the screw feeder, clean
the feed openings, and evaluate the correct operation of these units.
Check the cooling system of the burner
.
If leakage is detected at the joints, they shall be
fixed. Clean the controller with a vacuum cleaner, and check the operation of all its working
functions.
Eliminate all reported operational problems, and make a list of the required spare
parts for replacement during the annual maintenance.
–
Annual maintenance
(best at the end of the heating season when the boiler is off

condition of the electrical installation of the entire burner complex and eliminate all the
identified problems.
Check the drives of the screw feeder and the moving grates.
Add oil to the
gearboxes, if required.
Clean all air injection holes in the trailing grates with a vacuum
cleaner
.
Unscrew the fans, clean them inside, and clean with
a vacuum cleaner. Check the
mechanical functionality of the burner and confirm the readiness of all control elements.
Paint the cover of the burner complex, if required
.
Protect all sockets from adverse factors
that might occur
in the boiler room.
CAUTION!
Immediately prior to start of the heating season, a mechanical test
shall be carried out for all the units. This should be done after completion of the
