2. Important recommendations

Congratulations on your choice of a high quality product. We strongly advise you to read the following instructions in order to

guarantee the optimal operation of your appliance. We are sure that it will be entirely to your satisfaction and will meet with all of

your expectations.

1 Symbols used

Caution danger

Risk of injury and damage to equipment. Attention must be

paid to the warnings on safety of persons and equipment.

Specific information

Information must be kept in mind to maintain comfort.

ZReference

Refer to another manual or other pages in this instruction

manual.

2 Important recommendations

For a proper operating of the boiler, follow carefully the

instructions.

Any intervention on the appliance and heating equipment

must be carried out by a qualified technician.

The manufacturer is not liable for any improper use of the

appliance or failure to maintain or install the unit correctly

(the user shall take care to ensure that the system is

installed by a qualified fitter).

Keep children away from the boiler.

Incorrect use or unauthorised modifications to the

installation or the equipment itself invalidate any right to

claim.

Keep to the polarity shown on the terminals : phase (L),

neutral (N) and earth 4.

In the event of a power cut:

- Do not add any fuel.

Check regularly that the installation contains water and is

pressurised.

Keep the boiler doors closed during operation.

Open the boiler doors only during commissioning and

when adding fuel.

Do not burn unsuitable fuel.

2.1 Aeration

Position the air inlets in relation to the high ventilation vents in order

that the air is refreshed throughout the boiler room.

The minimum cross-sections and the positions of the fresh air inlet

and the air outlet must comply with prevailing regulations.

Do not obstruct the air inlets in the room (even partially).

Caution:

In order to avoid damage to the boiler, it is necessary to prevent the

contamination of combustion air by chlorine and/or fluoride

compounds, which are particularly corrosive. These compounds are

present, for example, in aerosol sprays, paints, solvents, cleaning

products, washing products, detergents, glues, snow clearing salts,

etc. Therefore:

- Do not suck in air evacuated from premises using such products:

hairdressing salons, dry cleaners, industrial premises (solvents),

premises containing refrigeration systems (risk of refrigerant

leakage), etc.

- Do not stock such products close to the boilers.

If the boiler and/or peripheral equipment are corroded by such

chloride or fluoride compounds, the contractual guarantee

cannot be applied.

4CBB 15/09/2008 - 300008541-001-E

2. Important recommendations

2.2 Maintenance

- The boiler must be serviced and fully cleaned and the flue gas

conduit swept by a qualified professional at least 2 times per year.

- We recommend taking out a maintenance contract.

- The boiler must be cleaned every 3 to 7 days.

- Check the seal on the boiler doors 1 time per month.

- Regularly check the level of water in the system and top up if

required, taking care that cold water is not added suddenly into the

boiler when it is hot. If this operation is repeated several times per

season, locate the leak and repair it.

Do not drain the installation, except in cases of absolute

necessity. For example: Several months' absence with the

risk of ice in the building.

2.3 Fuel

Use

- Broad-leaved hardwood (oak, beech, hornbeam, etc.)

- Broad-leaved softwood (birch, poplar, lime, etc.)

- Resinous wood (pine, fir, spruce, larch, etc.): To be used

occasionally (2 to 3 loads maximum and follow with the same

number of hardwood and softwood loads)

• Characteristics of logs that can be used

- Dry wood, stored under cover (for at least 2 years), with a low

humidity level (less than 20% of the gross mass)

- Logs with a maximum diameter of 150 mm

- Maximum length of the logs:

- For improved combustion quality, prefer shorter logs (25 - 33 cm)

split into cross-sections with a maximum diameter of 10 to 15 cm.

- For more regular combustion, better boiler autonomy and

improved annual efficiency, arrange the logs in an orderly manner

in the combustion chamber.

• Calorific power and energy content of various types of wood

• Equivalent between storage volume requirements

Do not use

- Chipboard panels

- Coated, painted or treated wood

- Wood containing pieces of metal

- Wood not stored under cover for at least 12 months

- Any fuel other than wood

3.1 Installing the heating

Depending on the heating installation, certain components can be

suppressed or added. Get your fitter to explain your installation to

you.

Désignation Fonction

CBB

Log-fired boiler with natural

draught

Burns wood in complete safety and protects the environment. Removes the heat from

the fumes given off by combustion and transfers it to the heating water.

EA108

Wall module for elevating the

return temperature

Used to read the return temperature. Stays off if the return temperature is lower than

60°C.

ML9

Thermostatic module for elevating

the return temperature

Used to prevent the return of water colder than 60°C into the boiler.

Logs The natural energy of wood is converted into heat by combustion in the Bioenergy

boiler.

Buffer tank Used for storing hot water extracted from the biofuel boiler (max. 85°C).

Compensates for any differences between heat production and needs.

Domestic hot water tank Maintains a reserve of domestic hot water for the household (e.g. shower) with an

electric back-up for the summer.

SV-matic 23 B

SV-matic 2233 BFS

Regulation

Optimally ensures the desired temperature on the premises and saves on fuel,

whatever the outside temperature.

Radiators or underfloor heating Transfers the heat from the heating water to the premises.

Heating pump Circulates the heating water from the boiler to the storage tank and from the storage

tank to the radiators and brings it back to the boiler where it is reheated.

Heating water and heating pipes Carries the heat produced in the boiler to the radiators.

3. Description

3.2 Safety

- Safety battery (delivered from the factory) to be connected to the

cold water by means of a control valve (option L33)

- Safety valve (To be installed by the fitter)

Motorised mixing valve

Adapts the outlet temperature from the boiler to the radiators in such a way as to

obtain the desired room temperature, whatever the outside temperature. This is done

by mixing the outlet water with the colder heating return water.

Pressure gauge Indicates the pressure in the heating circuit.

Air vent Ensures that there is no air in the heating pipes.

Safety valve Prevents too great an increase in pressure in the installation.

Expansion vessel Maintains a constant pressure in the installation and absorbs the water caused by

expansion.

L33

Safety exchanger control valve Use to trigger the safety battery which protects the boiler against overheating.

5. When the wood is well lit (about 20-30 minutes later), continue to

fill the combustion chamber.

Close the loading door.

4.3 Adding more logs - CBB 20

Only add more logs if the previous load has been consumed to

at least 1/4 of the original volume.

1. Open the loading door.

2. Add logs to the combustion chamber.

3. Close the loading door.
