wool layer.
When installing the smoke breeching in the chimney, one shall pay
attention to the chimney damper lever (it is necessary to provide a space needed
for its easy opening and closing).
Remember that combustion gases entering the chimney are hot,
therefore the chimney damper lever will heat up. To operate the
chimney damper, always wear protective gloves.

2.5. Boiler connection to the central heating system
The boiler is manufactured as an all-round unit that facilitates of various
types of connections.
Please make sure that all unused holes and outlets are
plugged.
The Boiler will operate correctly if the temperature inside the combustion
chamber will be sufficiently high, which means that the supply water (on the
boiler output ) shall have the temperature in the range of 70 to 80
O
C, and that
the water on return, not less than 55
O
C. Such operating parameters will protect
the boiler against low-temperature material corrosion.
Boilers have connections in the form of threaded G1½ stub pipes.
Connecting stub pipes with the installation shall be performed using appropriate
connectors. In order to properly connect the boiler, it is necessary to install all
accessories presented on Figures 1a and 1b.
If the boiler is fitted with a thermal safety valve, the valve’s sensor
shall be installed in the dedicated G½ muff (item 13 on fig.1a,b), then
install the safety valve.
