Page Operation and maintenance manual for the KSP Duo series boilers with feeders. The producer reserves the right to introduce technical modifications.
5. Check operation of the individual equipment: a) operation
of the fan, feeder, b) activation of the central heating pump,
domestic hot water pump and
fl oor pump, c) feeder (switch
for a change of revolutions on a box of the electric motor
should rotate to the right).
6. Turn o ff the fan. It feeds fuel to the feeder in manual mode.
Wait 2-3 minutes until coal appears in the feeder at the
height of air injection holes.
7. Spread the fuel aside. Place fi restarter and paper on it and
then pieces of small wood and fi re it up. After fi ring up the
chimney draught should suck fl ue gas to the convection
ducts of the boiler.
8. Start the fan and adjust air blowing to ensure uniform com-
bustions of the fuel when the wood and paper are fi red up.
9. When the stable fl ame is achieved, when heat on furnace
is generated, you should close the doors and switch the
controller to automatic mode (fan, feeder and pump/pumps
start to operate automatically). Select correct fuel from fuels
available in the controller. Flame in the furnace should have
a form of clean, intensive yellow
fl ame. Red, smoky fl ame
indicates too low supply of air, while white indicates that
supply is too large. If the boiler burner operates correctly you
should set: temperature of the central heating system (usu-
ally 60-80°C), the temperature of domestic hot water (45-
55°C), the temperature of a four-way valve and temperature
of
fl oor pump (in acc. to Controller user’s manual ).
NOTE! Charging and cleaning doors with burner should be
tightly closed during automatic operation of the controller.
NOTE! Temperature on the boiler should not be set below
57°C! It increases a risk of occurrence of a “dew point” what
considerably low-temperature corrosion in the heat below
57°C with simultaneous use of incorrect solid fuels leads to
accelerated wear and tear of the boiler and decreases its
e
ffi ciency exchanger. Maintaining temperature of feeding
water.
Whole combustion process will be controlled by the control-
ler when the boiler is fi red up (see Controller User’s Manual),
maintaining the set temperature of water in the boiler and tak-
ing into account building demand for heat.
4.3.1. Approximate output parameters
of the controller
The controller is pre-con fi gured, but its output parameters are
changed, depending on fuel used (eco-pea coal, fi ne coal, pel-
let, oats, lignite) and may require individual adjustments. They
should be adjusted depending on heat demand, type and qual-
ity (calori
fi c value) of fuel or depending on the development of
the heating system. Selecting correct parameters ensures eco-
nomical combustion of fuel.
The most important parameters for the controller, which
controls operation of the KSP Duo boiler are: feeding time and
break in fuel feeding. Parameters are selected depending on the
type of the product.
