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 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. In order to ensure correct
operation of the boiler, manufacturer recommends installation of a four-way
mixing valve or a heat accumulation tank.
Boilers have G3 (ø80) flange connections. Weld counter flanges be to
installation (supply and return) pipes then install seals and bolt the joint together
using screws (enclosed with the boiler). In order to properly connect the boiler,
it is necessary to install all accessories presented on Figure 1.
If the boiler is equipped with a thermal safety valve, install the valve
sensor on the G½ muff (item 13 on fig. 1). Install the safety valve.
Connect water supply pipe through the valve installed in the G¾ muff
(item 17, on fig. 1) using a flexible hose, which shall be disconnected after water
change is filled. When filling open all venting valves in the installation and
slowly close them until water overflows in the overflow pipe of the expansion
vessel (in case of open systems). Lossless installations may be supplied with raw
water, as long as its hardness is less than 10n. Otherwise the water shall be pre-
treated.
Install boiler accessories (handles and bakelite knobs).
