Please note that no additional items shall be connected to the open expansion vessel – espe-
cially not valves.
The size of expansion vessel is deducted from the following equation:

is the water volume in the entire installation. Diameter for the pipework of the expansion vessle
line should be round 25 mm.
Open expansion vessel is to be positioned vertically above the highest heating element.

Boiler operation
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
•
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.
2. Heating from below – put small amount of solid fuel over the fireplace pipes (“grid”) (no ash should
be present) and set up a fire. The draught regulator is at the maximum position. When the
fire begins to burn, add larger amount of fuel and set draught regulator on desired temperature /
position.
Make sure that lower boiler doors are closed during boiler use.
In case of an uncontrolled increase of pressure and temperature of the water in the boiler, due
to various reasons (such as power failure causing interruption of the circulation pump operation, circu-
lation pump defect, uncontrolled entry of air into system) close all air supply to the boiler or eventually
take the fire out if the safety conditions allow that (there are no inflammable materials in the area). In
case of power failure put the draught regulator in the zero position and the flap on the boiler chimney
take-up in the closed position.
It is obligatory to pay special attention that the pressure inside the installation is within
range (> 1,5 bar for closed systems). If the pressure is below the critical value, stop the boiler operation
and refill the system when the boiler is cold.
