Cleaning of exchanger with mechanical cleaning system is recommended on regular basis, namely
with repeatedly operated manual lever. This operation shall be delivered at least once a week. To
minimize time required for boiler operation, cleaning with fuel loading is recommended at the
same time. Long downtime of manually operated cleaning system may result in permanent
stoppage.
In case of boilers fitted with exchanger automatic cleaning system driven with electric motor
instead of manually operated lever, exchanger cleaning will be provided automatically during
burner cleaning.
Quantity of ash generated during combustion depends on quality of fuel and consumption by boiler.
Additionally to ash also trace quantities of carbon black may be generated. To remove ash firstly
open ash pan chamber access door, by removing two wing bolts located on sides. You can remove
ash from ash pan chamber by emptying ash pan tray. During ash removal cleaning of ash pan
chamber is recommended, by collecting with brush ash remains and fuel into ash pan tray.
Additionally during heating season, when checking quantity of ash, clean the Lower part of heat
exchanger. Depending on the type of boiler the washout hole of exchanger lower part is located:
Smart Fire SF11, SF15, SF22, SF31, SF41 and SF COMPACT – inside the ash pan
chamber, on the rear wall- before opening firstly lower the washout hole from holders by
moving it upwards;
Smart Fire SF11/130 – on the left from ash pan chamber access door- before opening
remove 4 fixing nuts (Figure No. 7, item 21).
When closing heat exchanger lower washout hole check gaskets in respect of any sign of wear,
as well as tightness of closed washout hole!
8.5 Maintenance and cleaning
Before commencement of works related to maintenance and cleaning, firstly put out and wait
minimum 1h to allow the boiler cooling down. After cooling down safe opening of masking
grilles, access doors and washout hole will be possible for the purpose of maintenance
!
After every heating season, before long downtime, during periodical inspection and repairs of
removal of defects careful cleaning of boiler is required and maintenance. Additionally every two
months check shall be conducted regarding boiler condition works shall be provided in terms of
cleaning and maintenance, if necessary. For this purpose every Smart Fire boiler is fitted with
washout hole in:
Heat exchanger top cover;
Exchanger lower part;
Burner;
Exhaust gas breeching.
According to the general principle, always clean Smart Fire boiler from the top to the bottom of
boiler steel body. Cleaning of boiler is necessary, if exhaust temperature significantly increased
during boiler continuous operation. If exhaust temperature increased suddenly over the allowed
maximum, cleaning of boiler is necessary.
Before cleaning, go to Controller Manual Control menu, and open the grate below the burner:
