1. PURPOSE
The boiler is purposed to heat domestic and public premises by the means of pellets. The boiler is
equipped with a steel water jacket designed for heating systems with water temperature up to 90º
C at a maximum super pressure up to 0,15 Mpa. Tests are run at pressure of 0,3 Mpa.
The boiler is designed and manufactured to work with A-class pellets only
( DIN plus 51731 ) with the following characteristics:
What are the pellets.
The pellets are produced by compressed wooden
waste left from the production of various furniture,
sawmills and others. This type of fuel is environ-
mentally friendly because in the production pro-
cess no agglutinate agents (glues, resins and oth-
ers) are added. Actually, the integrity of the pellets
is guaranteed by the lignite – a natural ingredient
contained in the wood itself. While the wood has a
calorie capacity of 4.4 kW/kg (15% humidity at 18
months drying), the pellets have 5.2 kW/kg.
• Material 100% pure conifer or broad-leaf wood;
• Diameter Ф6/8 mm;
• Length 20-30mm;
• Calorie capacity 5.2 kW/kg;
• Ash content < 8%;
The use of pellets with characteristics different from the recommended may result in power de-
crease, unstable and inconsistent work of the boiler.
Info: To ensure the proper work of the boiler the pellets must be stored in a dry place!
Recharging of pellets can be done during work, with the following sequence:
1. Open the bunker (located at the top of the product);
2. Fill the hopper, using non-combustible container;
3. Close the lid of the bunker;
Attention!!! Use gloves! Beware of hot surfaces!
The boiler consists of a boiler body, pellet hopper and a pellet burner. The burner can be fitted
to the right of the boiler or left, upon request.
The boiler body is constructed of sheet steel, stainless steel and corrosion resistant materials
throughout the flue gas circuit as well as all parts that may be in contact with condensate. Com-
bustion chamber is cylindrical and the flue pipes are arranged around this chamber.
At the rear of the boiler there are placed hydraulic connections as well as flue gas pipe and
condensate drain. The condensate discharges through a drain at the bottom of the boiler, where
a water trap is installed.
The boiler includes an automatic cleaning system of the burner plate, which wipes ashes onto a
manually removable ash drawer. It also includes an automatic water jet system for cleaning the
heat exchanger flue gas pipes.
