5.6. BOILER CLEANING AND MAINTENANCE
After continues operation, soot and ash accumulate on the boiler walls, which reduces the
performance of the equipment. The quantity of soot and the eventual tar depend on the
operation of the boiler, the type of fuel used, the parameters of the chimney draft and the
outlet water temperature. Cleaning of the boiler should be carried out according to need and
operating conditions, but at least once a week.
After stopping its operation, the ash from the grate should be cleaned. The smoke damper is
adjusted in the upper position and the heat-exchanger cover is taken off. Cleaning of the heat-
exchanger is done with the cleaning tools provided with the boiler (steel scraper and brush).
The soot fallen under the heat-exchanger is removed through the soot door. After cleaning the
boiler, the ash door is returned to its initial position.
During cleaning, it is recommended to check the condition of the ceramic blocks in the
combustion chamber. Damaged blocks are replaced with new ones.
Please strongly concider the timely closing of the flue gases flap of the boiler.
The ash must be stored (the ash has to be taken out by using appropriate
gloves) in fireproof reliable containers and to be transported to open space.
Other waste should not be stored in this container.
Maintenance of boilers series Bisolid Automat is done daily, periodically or annually.
In daily maintenance, the user must clean the unburned residues in the combustion chamber;
clean the ash gathered in the combustion chamber and dumps the ash-box (ash-tray).
For effective use, to prevent possible problems with the operation and for optimum life of the
boiler, it is very important that the user performs periodic maintenance of the equipment. A
periodical check on every 3 months is recommended. Such checks should be performed by
authorized service technicians and should include the following activities:
Check boiler
’
s combustion chamber and flue pipe, including the chimney. They
should be cleaned if necessary.
Check for leakages of inlet - outlet water, in and out of the boiler and water pipe
connections.
Check fittings including valves and flaps.
Check the fresh air fan of the pellet burner.
Check the circulation pimps.
Visual check of the grate.
Operation and safety control checks of the boiler hydraulic system.
Check the unloading valve.
The annual preventive maintenance of the boiler should be carried out only by authorized
technicians, before the start of the heating season. Before calling the service technicians the
user should clean the flue pipe and the chimney. The annual preventive maintenance carried
out by authorized service technicians includes the following checks and activities:
Position of the fuel hopper and the combustion chamber, insulation and insulation
ropes.
Boiler testing at operating pressure for adjustment of combustion by measuring flue
gas parameters if needed.
Checking and cleaning the boiler grate and surfaces from soot and ash.
