Page Operation and maintenance manual for the KSR Beta Pelet series boilers with feeders. The producer reserves the right to introduce technical modifications.
2.5. Fuel
Wood pellet is a primary fuel used in the KSR Beta Pelet: PN-EN
ISO 17225-2:2014 – class A1. Fuel used for combustion in the
pellet-
fi red boiler should have su ffi cient calori fi c value > 17 MJ/
kg, be dried (moisture content ~ 10%) and have size recom-
mended by the producer (6±1 mm and 8 ±1 mm). Use of moist
or too large fuel can lead to locking in the feeder and serious
failure of the boiler. Ash content should be lower than 0.5%,
the unfavourable chemical composition of the fuel can result in
sintering and formation of large amounts of dust and soot and
increased fuel consumption. Times given in the table on page 14
apply only to operation with suitable fuel.
2.6. Equipment
Prior to the boiler setting you should check the presence of addi-
tional tools and operation of the instrumentation. The complete
set should include: burner with a feeding system, fuel container, electronic controller, brush, hook, ash shovel, drain cock, fuel
swirlers.
3. BEFORE START-UP
3.1. Boiler room
• It should be a separate room with height not lower than 2.2
m in the newly constructed building (in the already existing
buildings the allowable height equals to 1.9 m).
• It should have arti fi cial lighting installed and have natural
lighting as far as practicable.
• It should have gravity ventilation in good working order,
including:
1. air-supply duct in the external wall with cross-section
not lower than 50% of chimney cross-sectional area on
height maximum 1 m over the
fl ooring or not lower than
200 cm
2
for boilers with power up to 25 kW or 400 cm
2
for boilers over 25 kW,
2. 2. separate air-exhaust duct on the internal wall with
cross-section not lower than 140x140 mm with an out-
let located under the boiler-room roof near the chimney.
NOTE! It is forbidden to use mechanical exhaust ventilation
in the room where the boiler was installed.
• Floor gully and fl oor with 1% slope towards the outlet
should be planned in the central part of the room.
• Flooring and walls in the whole room should be made of
non-combustible materials.
• The doors to the boiler room should open outwards.
3.1.1. Method for boiler setting
The boiler requires non- fl ammable fl ooring, in form of a foun-
dation, but it is allowed to place it on non- fl ammable wall base
with height not lower than 50 mm. The boiler should be placed
in a way ensuring free access to the equipment, allowing its
cleaning and maintenance. Therefore, while setting the boiler
it is recommended to maintain minimum distances from the
individual walls:
• distance from the front of the boiler to opposite boiler room
wall should not be smaller than 2 m,
• the distance of boiler side from the wall of the boiler room
should be lower than 1 m,
