4.3
Filling up the boiler and installation with water
Filling is done using the drain tap valve (to be found on the return line close to boiler). The filling process
is done when no air is coming out. Working pressure depends on the overall height of the system and the
open expansion vessel (1 bar for each 10 m is an estimate).
After the filling process is done, it is obligatory to close the drain tap valve, close the water supply to
the water-filling pipe and detach the water-filling pipe.
Pay attention to quality of water which is used to fill the heating system.
A
n expert should be entrusted with the mounting of the heating and the initial operation. This must
be a person who will take over the responsibility and guarantee the correct operation of the boiler and
of the complete central heating system. In the case of an incorrectly planned system with manifesting
deficiencies caused by the respective person’s incorrect installation of the system, which can again lead
to an incorrect operation of the boiler, the complete liability for the material damage and potential new
costs arising in relation to it is borne exclusively by the person who was entrusted with the mounting of
the central heating system, and not by the boiler manufacturer, sales representative or seller.

Boiler operation
5.1
Firing with solid fuel
First putting into operation is performed exclusively by a skilled person. Before putting in operation
please make sure that:
• boiler is connected on central heating installation properly
• boiler is connected on electric installation properly (when using pellet or oil burner)
• there is no air in the central heating installation and pressure is within range
• proper working cycle for circulation pump is chosen.
Heating by solid fuel (manual operation) can be performed in two ways:
1. Heating from above – put coal (or wood) over the fireplace pipes (“grid”) (no ash should be present).
The draught regulator is at the maximum position. Using a tiny piece of wood or coal, light a fire on
the top. When the fire begins to burn, draught regulator is set on desired temperature / position.
