cleaning and
upkeep
HINT!
In order to maintain appropriate combustion
efficiency, keep the convection ducts and
sheet metal inside the grid chamber
appropriately clean. Soot, dust and ash from
combustion shall reduce effectiveness and
capacity of the combustion process.

In order to clean the heater,
shut it down and
wait out the time necessary for the heat
exchanger to cool down.

procedure. Use
gloves, safety goggles and
head protection when servicing the heater.
In the grid chamber of the heater, pay particular
attention to the precise removal of ash and slag
from the grid grooves and chamber walls. Such
cleaning should be carried out each time the
heater is started up. Before cleaning, shut off the
heater with its main switch, and wait out the
period necessary for the heat exchanger to cool
down.
The exhaust ducts, in which volatile ashes
gather, should be carried out through the
inspection openings every seven to fourteen
days, depending on the fuel quality and humidity.
