CONTROLS
Set the controls to the recommended operating modes in order to achieve nominal thermal capacity and
furnace efficiency level
.
Desired water temperature is set via regulator – thermostat (Fig. 1, pos. 4). Control
switch on airflow regulator (thermostat) has following positions:
The air lid (shutter) attached to the airflow regulator (thermostat) regulates the combustion air feed entirely,
if all the other openings are closed.
The air lid (shutter) operates automatically and depends on the selected temperature as well as the boiler
temperature, which is signalled by sensitive temperature probe.

IMPORTANT:
Water temperature in the furnace when using wood, brown coal and briquettes for heating should not fall
below 70°C, in order to prevent condensation and corrosion of the furnace. Heating the area where the
furnace is located can be regulated by the furnace lid (Fig. 1, pos. 1), which has good insulating properties and
by opening/closing it, the furnace heating properties are increasing/decreasing.
