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.
Reference
Z
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
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.

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.
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:
Model CBB 20 CBB 30
mm 500 500
- 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.

3
(1 m x 1 m x 2 m)

(Drying of freshly cut wood)
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
- 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.

Used to read the return temperature. Stays off if the return temperature is lower than
60°C.
Used to prevent the return of water colder than 60°C into the boiler.
The natural energy of wood is converted into heat by combustion in the Bioenergy
boiler.
Used for storing hot water extracted from the biofuel boiler (max. 85°C).
Compensates for any differences between heat production and needs.

minutes.
- Thoroughly clean the heating surfaces in the boiler.
Precautions to take if there is a danger of frost
6. Stopping the boiler
Heating circuit:
Use a correctly dosed antifreeze to prevent the heating water
freezing. If this cannot be done, drain the system completely. In all
cases, consult the fitter.
Domestic hot water circuit:
Drain the domestic water tank and pipes.
Precautions to take in the event of prolonged
shutdown (one year or more)
- The boiler and the chimney must be swept carefully.
- Close the door of the boiler to prevent the internal circulation of air.
