TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL

2. PRODUCT DESCRIPTION

The WBS Active boiler is with built-up controller and
electric fan for forced air feed, designed for firing solid fuel
- firewood, Class B wood briquettes or coal.
Designed to satisfy the heating demands of medium to
large sized spaces. They are engineered for burning solid
fuel only and provide the option for fitting pellet, oil or gas-
fired burners.
This appliance complies with EN 303-5.
• Design. Boiler body is made of high-quality boiler steel
sheets with thickness of 5 mm for the combustion
chamber and 3 mm for the water mantle.
•Built-up controller. The electronic control unit controls
the operation of the flue fan, the circulation pump of
the central heating and the pump of the domestic hot
water system (DHW). The power of the fan is regulated
in relation to the fuel consumed and the momentary
chimney draft.
• Efficient. The flue gas makes a three-pass movement
around three water-filled barriers in the combustion
chamber on its 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
embraces the combustion chamber in full to utilize the
emitted heat most efficiently. To keep from losing heat
into the ambience, the boiler is insulated on the outside
by 50 mm high-temperature wool.
• Reliable and safe. The heat exchanging tubular grill is
protected by a replaceable metal grate. A complex of
safety devices provide for the safety of the appliance.
• Versatile. Designed for firing wood with option for
adapting to other fuel types by mounting a gas-, oil- or
pellet-fired burner on the specially designated flange
located on the lower door.
• Fuel loading door
• Cleaning door (combustion chamber)
• Air flaps for feed-in air adjustment
• Draft regulating flap, mounted on flue end
• Safety heat exchanger
• Safety devices of the boiler
The heating boiler can utilize only natural and untreated
wood, or coal. Pressed fuels and briquettes containing only
wood may also be used . Log length should be up to 330 mm
÷ 500 mm. Fuel moisture content must not exceed 20%.
For maximum utilization of the wood heating value we
recommend to use wood which has dried over a period of
1,5-2 years. High moisture content of the wood decreases
its heating value which in turn reduces boiler output.

4. TRANSPORTATION OF THE BOILER

We recommend to transport the heating boiler to the
installation site in its packaging placed on the pallet.
During transport and installation, depending on the weight,
appropriate safety equipment must be used in accordance
with Directive 2006/42/EC.
When transporting items weighing more than 30 kg, the use
of pallet jack, fork truck or other hoisting devices is a must.
The boiler is securely fastened with fasteners to a wooden
pallet.
Important: When installing the boiler, the wooden
*
pallet onto which the boiler is placed must be
removed by unscrewing the bolted connections
using flat ring wrench S13.
