In order to prevent any smoke leakage when opening the stoking door and stoking fuel,
take the following procedure:
- prior to stoking, close the air supply using the choker in the ash pan door and
slightly open the stoking door by roughly 1 to 1.5 cm in the frontal part of the
stoking door Wait for about 10 seconds until the smoke gases are sucked away and
then open the stoking door fully. After replenishing fuel, open the air supply
again. In the event of good chimney draft or if the filling shaft is full, the present
procedure does not need to be taken.
8.2 Ash Removal
In order to ensure good access of the combustion air for perfect combustion, the
remnants of burnt-out wood must be removed in time – namely the ash from the grate.
This shall be done by tilting the lever provided on the side wall of the boiler. The
movement is used to shift the grate, thereby making the ash fall through into the ash pan
space. In the event that remnants of clay are formed on the grate, remove it from the
boiler in operation by prolonging the movement of the lever. As a result, the cascade
grate will move clear and the coarse remnants of fuel will fall through into the ash pan
space. If the clay remains hanging from the grate, shake it off by shifting the lever more
rapidly.
The same procedure shall be taken when cleaning the boiler after the heating has been
completed. Make sure that remnants of ash which might potentially fall through beyond
the ash pan drawer and hinder proper insertion thereof do not accumulate in the space
for the ash pan drawer.
8.3 Cleaning the Boiler
In order to arrive at the most economical and as a result the most efficient operation
of the boiler, the internal part of the boiler body must be duly cleaned from time to time,
namely once a fortnight or a month (depending on the heating intensity and the fuel
used). That shall be done by vigorously scratching off any wall deposits by means of a
spatula or a steel brush included to the boiler as part of the accessories. The boiler shall
be out of blast when subjected to the cleaning.
