Operation with permanent burning
It is possible to keep the permanent burning, i.e. the fire in the boiler for the whole night without
need to heat up during the day, but only in the winter period. For the operation with permanent
burning it is necessary to prepare the boiler in the following way:
Lay some bigger wood logs (4–6 pcs.) on a glowing layer of fuel
Close the mixing valve partly – temperature of water in the boiler achieves 80–90 °C
The regulation flap controlled by thermal regulator is automatically closed and the fan is
stopped.
After the boiler is prepared in this way, the burning is kept for more than 12 hours. When the
boiler is in the operation of permanent burning, the water temperature must be 80–90 °C.
