3. FUELS
The heating boiler can utilize only natural and
untreated wood. Log length should be up to 330mm.
(for the PB18 model) and up to 500 mm (for the
PB25 and PB40 models). Pressed fuels and briquettes
containing only wood may also be used. 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.

value and water content.

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, suitable safety devices should 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 safely secured by means of anchor
fittingstoawoodenpalletofsizesА,B,C.Ithasthen
been stretch-wrapped to protect the housing from
scratching and dust buildup. The last element of the
packing is a height D cardboard box. The cardboard
box protects the boiler from ambient conditions
during transport.
*
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.

6. ASSEMBLY OF THE HEATING BOILER
*
The assembly, installation and set-up of the
boiler must be performed by a technician
authorized for such operations.
Installer must indicate to the user of the
installation the minimum clearances from
flammable materials and liquids.
6.1. Requirements:
- Boiler room must be frost-proof;
- Boiler room must allow for continuous access of air
necessary to maintain combustion;
- Boilers must not be placed in inhabitable rooms;
- All boiler rooms must have correctly calculated vent
depending on the boiler output. The vent must be
protected by means of a net or grate.
The size of the vent is calculated according to the
formula:
А = 6,02
*
Q - where:
А – area of the vent in cm,
Q – boiler output in kW
- Remove the packaging without polluting the
environment;
- Observe building supervision instructions, in
particular the existing Ordinance on combustion
devices and storage of combustion materials, on
building requirements applicable to installation sites
and on ventilation;
- The boiler must be placed on a foundation whose
surface area is larger than the base of the heating
boiler according to diagram 1;
- The boiler must be placed in a position which allows
for the easiest possible cleaning and servicing;
- Installation must be carried out according to
installation diagram 1 which shows the boiler
housing;
- No objects made of flammable materials or liquids
may be placed on/near the boiler;
