1.0. GENERAL

The hot water boiler CentroPlus has a modern design and construction. It is made out of controlled

high-quality materials, welded with the most modern technology and meets all special requirements for

connection to the central heating system.

1.1. BOILER DESCRIPTION

Steel hot water boiler CentroPlus has two separate combustion chambers inside the common boiler's

water chamber. The left combustion chamber is intended for firing with solid or liquid fuel. It has a large

heating area and small resistance, and large door which enables simple heating with big-size fuel. The

right combustion chamber is intended for firing with wooden pellets or liquid fuel and it is characterised

by 3-passes flue gas system with turbolators and large heating area which provides high boiler

efficiency. A large amount of water in the boiler enables longer pellet burner work (in that way it is

reduced the number of switching on the burner and extends the burner life time). The boiler cleaning is

very simply and can be done from the front or back side. Depending on the installed additional

equipment, there are three models of boiler use:

- solid fuel firing,

- solid fuel and wooden pellets firing,

- solid fuel and EL fuel oil firing.

The boiler is supplied without above mentioned additional equipment, which can be additionaly

ordered. The additional equipment is delivered in a separate packing and it is installed onto the boiler

after the boiler is istalled into the boiler room and connected to the central heating system.

1.2. DELIVERY OF THE BOILER CentroPlus

Due to easier transport and positioning into the boiler room, the boiler CentroPlus is not delivered with

built-in thermal insulation and casing (it is delivered separately):

- the boiler body with boiler door is delivered on a wooden pallet (with lid of the left firebox door,

lid of the right firebox register, ashtrays, left and right firebox grates and turbulators);

- the cardboard box with boiler casing, thermal insulation, themometer, draft controller ( such

as CALEFFI 543 or ESBE ATA200), back ash box, cleaning accessories (accessories holder,

brush, scraper and poker), protective box for extension for the pellet burner and set of screws

and bolts.

1.3. OBLIGATORY ADDITIONAL EQUIPMENT FOR THE BOILER CentroPlus

WHICH IS INSTALLED TO CLOSED CENTRAL HEATING SYSTEM

CentroPlus 25/35:

- thermal valve (such as CALEFFI 543) -1 piece

CentroPlus 50:

- thermal valve (such as CALEFFI 543) -2 pieces

- thermal protection exchanger Centrometal - 2 pieces

General, boiler delivery, additional equipment

Technical instructions CentroPlus

1.4. ADDITIONAL EQUIPMENT FOR THE BOILER CentroPlus 25/35

Depending on preferred boiler use it is necessary to install appropriate additional equipment to the

boiler:

1) Additional equipment for solid fuel / wooden pellet firing:

- pellet burner CPPL-35, digital boiler control unit CPREG for pellet burner CPPL-35;

- pellet tank CPSP;

- pellet feeder CPPT 14-35.

2) Additional equipment for solid fuel / EL fuel oil firing:

- boiler control unit EKO-CK/CKB for the oil burner;

- oil burner with appertaining equipment.

1.5. ADDITIONAL EQUIPMENT FOR THE BOILER CentroPlus 50

Depending on preferred boiler use it is necessary to install appropriate additional equipment to the

boiler:

1) Additional equipment for solid fuel / wooden pellet firing:

- pellet burner CPPL- 50, digital boiler control unit CPREG for pellet burner CPPL-50;

- pellet tank CPSP;

- pellet feeder CPPT 40/50.

2) Additional equipment for solid fuel / EL fuel oil firing:

- boiler control EKO-CK/CKB for the oil burner;

- oil burner with appertaining equipment.

2.0. POSITIONING AND ASSEMBLY OF THE BOILER/ADDITIONAL EQUIPMENT

The boiler body is delivered on a wooden pallet on which it is fixed with four holders. Before placing the

boiler body into the boiler room, it should be removed from pallet (Figure 1.). The boiler positioning,

assemble and installation of the additional equipment must be performed by a qualified person. We

recommend to place the boiler on a concrete base which is 50 to 100 mm higher than floor. The boiler

room has to be frost-resistant and ventilated. The boiler has to be placed in a way which enables

connection to the chimney (see point 4.0) and supervising the boiler and additional equipment,

cleaning and maintenance (see Figure 4a.). The boiler casing assemble has to be done in accordance

with the instructions (Figure 2.).

2.1. SOLID FUEL FIRED BOILER (EQUIPMENT FOR WOODEN PELLETS AND

OIL IS NOT BUILT-IN YET)

Draft controller has to be installed to the boiler left side (such as CALEFFI 543, ESBE ATA200) and

connect it by a chain to the movable lid on the boiler lower door. The electrical connector and heating

pump connect according to the electrical scheme (Scheme 5.).

2.2. SOLID FUEL/WOODEN PELLETS FIRED BOILER

To the left boiler side install draft controller (such as CALEFFI 543, ESBE ATA200) and connect it by a

chain to the movable lid on the boiler lower door. The pellet burner CPPL install onto the right lower

door. The pellet control unit CPREG install to the casing cover. Above the right lower door (on the

casing) install the microswitch. Place the pellet tank CPSP with the pellet feeder CPPT next to the

boiler, to its right side. Detailed desctiption of pellet equipment is described in “Technical instructions

for startup and setting of the Cm Pellet-set for the CentroPlus and CentroPlus-B boilers (solid fuel and

wooden pellets fired)” and in “Technical instructions for pellet tank and screw feeder which are

delivered with equipment for wooden pellet firing.”

2.3. SOLID FUEL / EL OIL FUEL FIRED BOILER

To the left boiler side install draft controller (such as CALEFFI 543, ESBE ATA200) and connect it by a

chain to the movable lid on the boiler lower door. Remove the blind plate from the lower right door from

the ceramic exstension for the oil burner. The oil burner has to be installed to the plate opening with

ceramic and connected to the fuel supply. Install the boiler control unit EKO-CK/CKB for oil burner to

the casing cover and connect it to the burner, electical connection and heating pump according to the

electrical scheme 6.
