DESCRIPTION

Conditions to be checked before installation

Install the pellet unit in a place where abduction of the exhaust gas and the noise of the unit will not cause

any inconvenience to the users of the equipment and the residents of the surrounding area.

Do not install the unit near any place where there is frequent access to people such as stairs or emergency

exit.

Provide adequate space for the operation of the unit, its inspection and repair (1 m or more from the top, left

and right side).

Do not install the unit in an area that does not have enough ventilation. The lack of oxygen causes

incomplete combustion.

Never install the unit outside in the open space exposed to the weather conditions, it will create problems in

its operation and its lifetime.

Installing the unit directly on the floor the base of the unit can corrode reducing its lifetime.

Place the unit on surfaces of uninflammable material, 50 mm above the floor like concrete blocks.

The installation of the unit should be executed by a qualified technician according to instructions provided by

the user manual.

Install a fire extinguisher in the boiler room.

Do not store wood and do not place the unit near combustible materials. Keep the surroundings clean.

Contact customer service when the unit needs repair.

INSTALLATION

Plumbing installation of the boiler to the heating network

The water supply to the heating network

and the domestic water should be derived

from the water supply network.

The presence of calcium and salts in water

can cause premature corrosion in the

boiler and other problems.

Ensure to keep hot the boiler pipes.

The pipes should not be exposed to frost.

The pipes should be insulated with an

insulation thickness of more than 25 mm

in order to be protected against frost

(50mm in cold areas).

In case of frost occurring on the plumbing

of the heating network, the antifreeze

protection available within the unit, in the

area controlled by the thermostat will not

function adequately.

In order to select the size of the expansion

tank estimate that for every thousand

calories of boiler is required at least a liter

in the tank.

The expansion tank and the safety valve

shall be checked regularly to ensure good

operation and long lifetime of the boiler.

If the safety valve opens often then it is

due to increase of the pressure of the

network.

Check the automatic water filler of the

heating network and the pressure in the

expansion tank and fill with air (1 bar) if it

is deemed necessary.

Connect the safety valve outlet with a tube

in the drainage to drain of the water.

The backflow valve is positioned to prevent the natural flow of

water to the radiators when we ask for hot domestic water during

the summer months.

INSTALLATION

WRONG POSITIONING OF VALVES

The valves should never be

placed:

• between the boiler and the

safety valve

• between the boiler and the

expansion tank

In this case, if the burner is

activated with closed valves the

boiler will be destroyed.

Before connecting the domestic water in the boiler measure the pressure of the water supply.

Then adjust the expansion tank of the water supply at the same bar and insert a corresponding

security valve. E.g. assume the water supply is 4 bar, then choose a safety valve of 6 bar and

adjust the expansion tank at 4 bar.

INSTALLATION

Chimney installation

Install the chimney in such a way that the

exhaust gases come out unaffected by

pressure, rain, winds.

Draining

Install the chimney from the exit of the boiler to the vertical part of the

chimney inclined 5 degrees downwards.

1m or longer

Drainage device

1m or longer

Install the chimney component that accompanies the unit for drainage.

The vertical part of chimney be more than 3 meters of high from the

boiler and at the end of the chimney insert a T to prevent incomplete

combustion due to winds.

It may be caused increased exhaust heat, do not store flammable

materials near the chimney.

Install the chimney by taking into account the appropriate measures and

adequate distances. You should ensure that there are no flammable

materials around the chimney in the minimum distance of 30 cm.

ATTENTION:Installation of additional chimney

If there is a high building or an obstruction within 1 m next to the

evacuation of combustion gases, exceed the chimney 1 m higher than

the top of the building.

The height of the vertical piece of the chimney should be 3 times or longer

than the horizontal piece.

If the abduction of the exhaust gases is executed in a zone of pressure

winds, this can lead in causing excessive soot from incomplete

combustion resulting in reduced performance of the boiler or create some

damage and the unit will not work normally. To prevent this, the

abduction of the exhaust gases should be executed off pressure winds

zones.

If the chimney is longer than 4 m with 2 angles, increase the diameter of

the chimney (Ø150Ø200, Ø200Ø250).

zone

Following the installation work of piping and chimney, pour into the boiler the anticorrosive liquid

accompanying the unit after you first dilute it with enough water.

Then fill with water the boiler, the pipes and the radiators.

Electrical connection of the unit

Use a power supply outlet

exclusively for the unit.

Connect the two green wires

(phase - neutral) in the circulation pump.

Installation and connection of room thermostat

Place the thermostat base on an internal wall of the room, in a distance of 1,20 - 1,50 m from the floor.

Extend and connect to the thermostat the two wires red and white expanding left of the inner control

BCX4000C2 located within the unit.

Connect the cable to the back of the thermostat.

Connect the marking wires of the room thermostat according to the polarity when you wire.

White (-), red (+) and place the thermostat in its place.

ATTENTION

• Do not place electrical cords e.g. AC120V type

because the communicating between the room

thermostat and the pellet unit may not be good.

• Do not bury under the ground or put the

thermostat wire in the same tube with the electrical

cable 230V. It can cause problems in the communi-

cation between the room thermostat and the unit

panel.

• Do not place it in a place exposed to sunlight and

high humidity.

• Do not place it in a place that can easily be reached

by children.

OPERATION

Heating mode

1. Setting the room temperature

By pressing consecutively the button select on the screen of

the thermostat the indication with the sun.

The screen displays two two digit numbers. The left two digit

indicates the temperature of the room, where the thermostat is,

at that time. The right two digit number indicates the

temperature we have chosen.

2. Setting the heating water temperature

+/-

3. At the bottom of the screen of the thermostat display rectangular

bars.

With this buttons increase or decrease the bars on the

thermostat screen to select the desired water temperature in the

boiler and the radiators. With the first bar you select 45°C, with

the second 55°C, the third 65°C, the fourth 75°C and the fifth

85°C.

Select the water temperature in the boiler depending on the

outdoor temperature. The lower the outdoor temperature, the

more high temperature you should select in the boiler water.

Heating mode via timer

1. By pressing consecutively the button select on the screen of the

thermostat the indication with the clock signal to select the

operation mode through timer. The screen of the thermostat

displays two two digit numbers.

The left two digit indicates the operation time of the boiler (10 to

90 minutes).

With the button (+) / (-) (▲) / (▼)we determine the operation time.

With the button (+) / (-) (▲) / (▼) we increase or decrease the

desired temperature

OPERATION

Heating mode via timer

2. Then press the button and the right two digit number

corresponding to 1 up to 24 pausing hours begins flashing.

So if in the first left two digit number we select No. 20 and in the right two digit number we select No. 02 the

unit will operate for 20 minutes and will stop operation for 2 hours.

When you finish setting up in this situation, the unit will initiate its operation with the adjusted pausing time.

Antifreeze mode

1. By pressing consecutively the button select on the screen of

the thermostat the indication with the suitcase sign to select

the antifreeze mode.

After selecting the antifreeze mode on the thermostat screen,

the left two digit number will indicate the temperature in the

room at that time and on the right side of the thermostat

screen will display the number 08.

If the temperature drops below 10°C in the room where the

thermostat is placed, the circulator will be activated and if the

temperature drops below 8°C the burner will be also

activated.

This will protect the boiler and heating network against frost.

Hints for the operation of antifreeze mode

The operation of the antifreeze mode during low temperatures maintains the proper temperature in the

boiler body, in order for the tubes in the house and the pipes connected to the boiler for heating to be

protected against frost.

When you are away from home during the winter, leave the power cord connected to the boiler. If you

leave the house for several hours, open a tap in the kitchen so that a very small amount of water will

drip and thus prevent freezing in the circuit of hot domestic water.

With the button (+) / (-) (▲) / (▼) we determine the hours of

pausing operation of the boiler.
