Blower air volume control
The correct volume of air needed for combustion can be determined by
watching the colour of the flame: optimum colour is yellow. A smoking, dying
down flame requires more air. Sharp, short flame, some times lightly bluish or
transparent indicates too much air. The air volume can be modified via the
control box menu. Additionally the blower has mechanic throttle to control air
flow. The throttle is equipped with a spring preventing complete shut-off of air
supply.
Feeder maximum temperature adjustment
The flame sensor measures the temperature on the feeder. The upper
threshold of the feeder anti-overheat protection is set from the main control box.
If the feeder temperature exceeds the preset value, then the controller will stard
the feeder for a pre-programmed time of 8min. During this time air supply will
be shut off and pumps will be on. After the fuel is “pushed out”, the controller
will switch off the feeder and will no longer switch it on, even if the feeder
temperature is still high.
3.3 Burning
3.3.1. Ignition
For ignition, use dry duel with humidity content of up to 20%. Firelighters
may be used, paper (except from newspapers) or cardboard. A batch of fuel shall
be fed into the head’s combustion chamber manually, after the mode is switched
to LIGHT, on the controller, with the feeding being switched on. When the fuel
appears on the burner grate, it shall be ignited and the blower shall be started
using the blower fan switch.
After about 5 minutes the flame should stabilize. Then, one shall press
EXIT and the controller will resume operation in automatic OPERATION
mode. If the fuel batch fed puts out the flame, the procedure shall be repeated.
The activities are the same for both head types: the cast-iron head requires no
further maintenance and after ca. 1 hour may be left unattended.
In case of ceramic heads, first ignition of the boiler involves also drying
and burning-in the combustion chamber (use dry fuel with humidity content of
up to 20%). The process shall last ca. 3 days. The combustion chamber burning-
in shall be performed in such a way, so that the brick colour lightens. Having
completed with the boiler drying, it is necessary to stop and cool it down
naturally by some 12 hours. Before the next (and each successive) start of the
feeder, in order to prepare it for continuous operation under full load, it is
necessary to warm up the ceramic chamber first, then switch to continuous
burning. For burning, use fuel with moisture content of 20 to 40% (provided that
the burning process runs continuously, in appropriately preheated chamber).
Please keep in mind that if the chamber is not sufficiently heated up, wet fuel
