Components
2.2. PELLET BURNER CPPL-14, CPPL-35, CPPL-50 I CPPL-90
Pellet burner CPPL-14 (nominal power is 14 kW, for the boiler EKO-CK (B) P 20 + Cm Pelet-
set_Touch 14), CPPL-35 (nominal power is 20-35 kW, for boilers (EKO-CK (B) P 25/30/35/40 +
Cm Pelet-set_Touch 35), CPPL-50 (nominal power is 40-50 kW) for boilers EKO-CK P 50/60 +
Cm Pelet-set_Touch 50 i EKO-CKB P 50 + Cm Pelet-set_Touch 50), CPPL-90 (nominal power is
60-90 kW) for boilers EKO-CK P 70/90/110 + Cm Pelet- set_Touch 90) are composed from quality
components and made from certified construction materials. The burner has a high efficient fan
which with the help of a special designed burner grate forms the flame as the classical burners
do. In the burner also the electric heater is located which with the help of the controller when
needed automatically fires the pellets. The embedded photocell serves for the detection of the
flame in the burner. The special combustion chamber shape enables a quality mixing of air and
fuel which result is a high combustion efficiency. Depending on the burner operation phase and
the set power, the fan's rpm is changing, ie the burner air supply. The buner is designed to be
mounted on the lower boiler door CPDV on the prepared apertures. The burner is factory prewired
and it is necessary to connect it with the boiler controller CPREG-Touch.
2.3. DIGITAL BOILER CONTROLLER CPREG-Touch
Sophisticated digital boiler controller CPREG-Touch steers the burner according to the need for
heating and production of domestic hot water. The characteristics of the boiler controller CPREG
– Touch : microprocessing controller, safety thermostat, safety pressure switch, microswitch for
the lower boiler door, the controller starts and stops the burner according to the set temperatures
and operation regimes, regulates the pellet supply via the pellet feeder, operation according to
(heating and DHW) or (only DHW) regime, boiler protection from condesning, notes the current
boiler status on the screen, error writings on the screen. For a detailed operation description and
the setting mode of the individual parameters look into the technical manual Cm Pelet-set _Touch
14_90 – REGULATION– USER.
2.4. PELLET FEEDER CPPT-Touch, CPPT-50-Touch and
CPPT-90-Touch
The transport of pellets from the tank towards the burner is done with the help of the pellet feeder
CPPT / CPPT-50 / CPPT-90-Touch. In the tube (pellet feeder) an “ Archimedean “ spiral is located
which by the help of the electric gearmotor transports the pellets from the tank over the flexible
tube into the pellet burner.The electric motor is factory prewired and it is necessary to connect it
with the connector on the back side of the boiler controller CPREG-Touch.In case the power cable
is damaged , the replacement of it needs to be done by an authorized serviceman or by a trained
person in order to avoid the danger of a power (electric) stroke or damage.
2.0. COMPONENTS
2.5. PELLET CPSP / CPSP-800
The pellet tank CPSP / CPSP 800 is positioned on the right side (recommendation) or on the left
side next to the EKO-CK P or EKO-CKB P boiler. After positioning it is needed to mount the pellet
feeder. Before filling the tank it is needed to open the lid which is located on the top of the tank and
to check for possible rigid objects or other foreign bodies which may not be present here. The
pellet tank mounting mode is described in the installation manual for the pellet tank.

Figure 1a. Minimum distance from the room walls
The boiler positioning and assembly must be done by an expert. The boiler needs to be positioned on a
solid and horizontal surface. We recommend the positioning on a concrete surface / base with the
height of between 50 and 100 mm. The boilerroom must be safe from freezing and good ventilated. The
boiler must be positioned in the way to enable its correct connection with the chimney (see point 4.3.) ,
and in the same time to allow the normal work with the boiler and the additional equipment, monitoring
during the operation, boiler cleaning and its maintenance (Figure 1a and 1b).
WARNING:
Flammable objects may not be situated in the boiler and within the minimal distances shown on
the figures 1a and 1b.

4.3. CONNECTION TO CHIMNEY
4.2. OPENING FOR FRESH AIR (FRESH AIR SUPPLY)
Q - boiler output in kW
2
A - opening area in cm
A = 6,02 Q
Each boiler room must be equipped with an opening for supply of fresh air which is dimensioned
in accordance with boiler output (minimum opening area according to the below shown equation).
Such opening must be protected with a net or grate. All installation works have to be performed in
accordance with valid national and European standards. Boiler must not operate in flammable
and explosive environment.
Properly dimensioned and built chimney is a precondition for safe boiler operation and heating
efficiency. A chimney must be thermally insulated, gas-tight and smooth. Cleaning door must be
made in the lower part of a chimney. Chimney made of bricks must include 3 layers with central
insulation layer made of mineral wool. Thickness of thermal insulation should be min. 30 mm of
chimneys is built against to interior wall, and min. 50 mm if it is built on the outer side. Internal
dimensions of the chimney light diameter depend on chimney height and boiler output
and they have to be selected in accordance with diagram shown in picture 7. The chimney
usable height is the measure from connection spot of smoke pipe to the chimney top. As these
boilers can be fired with wooden pellets at any time, chimney has to be selected according to the
wooden pellets diagram. Fuel gas temperature at the chimney exist must be min. 30°C higher
than condensation temperature of combustion gases. Selection and building of a chimney must
be made by a professional. Required maximum distance from boiler to chimney is 600 mm, and
minimum distance is 300 mm. Uptake tube must be installed at an angle (min. 5°) with a gradient
from chimney to boiler (Figure 2). In order to prevent condensate from chimney to enter the boiler,
uptake tube must be placed 10 mm deeper into chimney. Connecting uptake tube between boiler
and chimney must be thermally insulated with a mineral wool layer having thickness of 30 to 50
mm. All installation works must be made in accordance with valid national and European
standards.
