Operation and maintenance manual for the KSP Spark series boilers equipped with feeders. The producer reserves the right to introduce technical modifications.
4.6. Cleaning and maintenance
4.6.1. Cleaning ash drawer
Check ash container every two days and empty it if necessary.
Ash drawer should be emptied on regular basis to ensure that
combustion residues are not reaching the base of the furnace.
Ash should be stored in a metal container with tight cover. The
container should be placed on the non-combustible substrate or
directly on the ground, in suitable distance from the combustible
materials, until the ash is completely quenched.
NOTE: Hot glow remains in the ash for a long time!
4.6.2. Furnace cleaning
If the flame if reddish or weak, and the smoke is emitted, it
can indicate that there are ash residues or formed deposits in
the furnace, preventing correct operation of the boiler and they
should be removed.
Remove furnace every two days. Lift it slightly and then
clean from ash and possible deposits. Pay special attention to
unclogging the holes using the sharpened tool. This operation is
particularly important if the pellet of unknown quality is used.
The frequency of this operation depends on the frequency of
boiler operation and type of fuel.
It is recommended to inspect the base of the furnace, clean-
ing it from possible ash.
NOTE: before start-up of the boiler you should check
whether the furnace is tightly moved to the rear towards
the flap and igniter tube is inserted to the opening in the
furnace.
