Technical Description
The boiler is designed to work on burning wood pieces with a maximum length of 550 mm
(according the boiler type)and a maximum water contents of 20 %. As an alternative type of fuel wood
briquettes up to ø 50 mm and wood waste can be used. If this type of fuel is used, the fuel channels tend to
become obstructed more intensely.
The boiler shell is made from high-quality steel plates as a welded assembly. The combustion
chamber is equipped with a water grate for the passage of combustion gases. The grate is installed in the
bottom part of the chamber. Space for ash is available underneath the grate, and an ashtray.
The front face of the upper part comprises a removable door and the lower part comprises an ash
door.
The outside surface of the boiler body is thermally insulated with mineral wool inserted beneath
sheet metal covers of the boiler’s outer shell.
The boiler is connected to the heating system through threaded connection, with the size of the connecting
thread being G 1 1/2 ´´. Filler coupling unit: G ½´´.
The boiler is intended to be installed within open and closed heating systems.
D Boiler’s Strong Points :
Enables the burning of wood as well as wood waste;
The depth of the combustion space as great as 550 mm;
High heating coefficient of performance - low fuel consumption;
Thermostatic Output Regulation
Option of chimney draught control (chimney draught control system)
Maximum burning time: 12 hours (under low-output / economy mode)
24 months warranty.

Operating Regulations and Installation
Boiler Preparation for Operation
Before the boiler is put into operation, it is necessary to ensure that your heating system has been filled with
water and deaerated. (The water must meet the requirements of STN 07 7401:1992 [Slovak Technical Standard]).
In order to ensure proper and safe operation, your wood-fired boiler must be operated in accordance with the
instructions contained in this operating and maintenance manual. The boiler may only be operated by adults.
Boiler Installation
The boiler may only be installed and connected to the chimney by personnel qualified for this type of job.
A carefully prepared heating system project is a must for the user to get full satisfaction.
Placement
The boiler is intended to be installed within the basic environment (under STN 33 0300).
The boiler must be installed in such a manner that free space containing an area of approximately 1 x 1 m
remains available in front of it.
The minimum distance between the rear part of the boiler and the adjacent wall must be at least 400 mm.
The boiler should be installed on a fireproof pad overlapping the boiler’s floor plan throughout its
perimeter by at least 100 mm.
We recommend that the boiler be placed on a concrete footing with a minimum height of 50 mm.
Connecting Boiler to Heating System
The boiler is connected to the heating system through threaded connection, with the size of the connecting
thread being G 1 1/2 inch.
You may both fill and empty your heating system through the ½ ´´ spherical valve located at or near the
bottom rear of the boiler. Deaeration valves on the radiators must be open during the filling of the
heating system and the system should be filled slowly so that the air can escape easily from al the venting
points. After the heating system is fully filled, the deaeration valves must be shut off.
The quality of heating water must comply with the requirements of the applicable technical standard
(STN 07 7401).
The heating system must be equipped with a manometer.
A thermostatic draught control unit is necessary to be installed on the boiler (supplied with the boiler).
