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 wood-
en waste left from the production of various
furniture, sawmills and others. This type of
fuel is environmentally friendly because in
the production process no agglutinate agents
(glues, resins and others) are added. Actual-
ly, 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 decrease, 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!
