2. PRODUCT DESCRIPTION
WBS-A Magna heating boilers are designed mainly for burning solid fuels - wood,
wood briquettes class B and coal. Designated for indoor climate heating of large
premises - residential and public buildings, industry workshops, etc. They can be
either connected to open- or closed central heating installation circuit.
These impressive-sized renewable energy heating devices combine state-of-the-art
engineering solutions and high-grade materials. Nevertheless, they are easy for
transportation and installation.
WBS-A 450 Magna boilers are designed and manufactured in accordance with EN
303-5.
• Design. Boiler body is made of high-quality boiler steel sheets with thickness of
8mm for the combustion chamber and 5mm for the water mantle.
• Automatic control (Controller).
The automatic control is regulating the functions of the intake air fans and the
circulating pumps of the central heating(CH) and the domestic hot water (DHW)
circuits upon constant temperature indication signals. The power of the intake fans
can be regulated in a broad range depending on the used type and condition of the
fuel and also the chimney draught.
• Efficient. The flue gases make a three-pass movement on their way to the chimney.
This way the gas is cool when it leaves the boiler and its energy has been transferred
to the water in the mantle. The water mantle fully embraces the combustion
chamber to utilize the emitted heat most efficiently. To prevent from losing heat into
the ambience, the boiler is insulated on the outside by 100 mm high temperature
effective mineral wool.
• Versatile. Designed for burning solid fuels. The boiler has an option to adapt to
other fuel sources: by mounting a pellet burner BURNiT PELL 300 Mega or PELL 500
Mega. The mounting is performed by a specially designed opening on the lower door
with the help of special mounting kit for each burner.
• Fuel loading door
• Cleaning doors
• Two blower fans with safety valves for intake air control
• Draft regulating valve, mounted on flue end
• Safety devices of the boiler - a complex of safety devices provide for the safety of
the appliance
