feeding box and tighten the screws with enclosed nuts M8. Put a gasket onto the feeding box and
put a feeding tube onto it (faced toward the pellet tank, either on the left or on the right side and
tighten it firmly using enclosed screws M4 x 15. Connect 3-pin plug of the backfilling sensor /
temperature sensor'' the supply pipe in 3-pin connector which is attached to the feeding box. PVC
and silicone pipe, which is at its one end fixed to the pressure switch at the burner, should be
placed (and shorten if necessary) onto appropriate connector on the boiler door. Place cover onto
preinstalled screws and tighten them firmly.
Only CPPL-14: put ceramic nozzle onto holder located on the top of burner head.
Installation of the burner onto lower boiler door
c) On the top side of boiler plating, using enclosed screws 3.9 x 9.5 mm, fix boiler control unit
CPREG, insert the safety thermostat sensor and control unit sensor into the sleeve on the boiler
(on the top side on EKO-CK P (EKO-CK) boiler, and on the front side on EKO-CKB P (EKO-CKB)
boiler; sensors should run to the sleeve along lateral side of the boiler) and connect wires by 4-
poles and 6-poles connectors onto the burner and then fix the connectors to the burner body. Fix
wire cable between the control unit and burner to the boiler casing by supplied plastic cable holder
(fix cable holder onto boiler casing with tapping screws 3.9 x 16 mm).

e) Assembly the pellet tank CPSP according to technical instructions and position it next to the right
or left boiler side onto horizontal surface. Align tank bottom with the boiler bottom and align the
front tank side with the front side of boiler plating.
f) Place the feeder CPPT into tank and connect it by a transparent flexible tube with a pellet burner
CPPL. Fix one end of transparent flexible tube to the burner (onto the feeding tube) to backfilling
sensor / temperature gauge on inlet tube, and other end should be fixed to the feeder so that the
tube will not become loosen. Transparent tube between the feeder and burner must be as straight
as possible so that pellets can fall smoothly from the feeder into the burner (if pellets remain in the
tube, it should be straighten and shorten, if necessary).
g) Connect a wire for power supply to the screw feeder CPPT to the connector (2) on the back side
of the control unit CPREG.
h) If sanitary water is prepared by using the boiler control unit, or the system installed one or more
accumulation tank (CAS) a sanitary water sensor should be fixed to connector 4 instead of a
jumper wire.
h1) If the sanitary water is prepared with the help of boiler control unit, sensor should
be placed in domestic hot water tank (Figure 1a).
h2) if it is installed one or more accumulation tanks (CAS) it is necessary to set the
domestic hot water sensor at the lowest sensor sleeve on the last accumulation
tank (CAS) or in a sensor tube below the water level we want to warm up (see
Figure 1b). In this case the hot water sensor has no direct connection with the
preparation of hot water (Figure 1b).
i) If used Telecontrol or cascade manager they is connected in place of a room thermostat
(Connector 3).
j) A jumper wire is factory installed in the place of room thermostat (connector (3). If an adapter is
used for ‘’more zones’’ control (optional equipment), a jumper wire in the connector (3) must be
put.
k) Do not connect boiler control unit to power supply via a built in thermostat on the boiler (if there is
a thermostat on the upper side of EKO-CK P/CKB P (EKO-CK/B) boiler).
