position. This position is marked by a line for an easy orientation – see Picture C. The power output
of the boiler can be increased by making the opening gradually bigger.

The mouthpiece for adding water as well as the smoke hub are located on the center axis of the rear
part of the boiler. The mouthpiece for water output is moved sideways from the center axis by 140
mm. The upper part includes a G3/4" mouthpiece for attaching the regulator of combustion air and a
G1/2" mouthpiece for attaching a sensor of the overheating fuse device. The bottom part has a
G1/2" mouthpiece for the discharging and feeding valve.
Boiler walls are thermally insulated by a 40-mm layer of mineral wool and covered with treated
cover plates. The stoking, cleaning and ash doors are made of sheet-metal, surface-treated parts and
they are thermally insulated as well. The front cover plate is furnished by the following informative
measurement devices for monitoring temperature and pressure of the heating water inside of the
boiler:
Capillary thermometer TCS 48
(technical data – scale range: 0 to 120 °C; measuring range: 20 to
100 °C; accuracy: ±4% of the scale range)
Manometer MCS 48
(technical data - scale range: 0-4 bars; scale divisions: 0.1 bars; accuracy:
±2.5% of the scale range)
