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 Used symbols

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

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 open the boiler doors.

- 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 Ventilating the boiler room

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:

- 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.



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

mm 330 530 530 330

- 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.

Wall module for elevating the

return temperature

ML9

Thermostatic module for elevating

the return temperature

Logs

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.

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.

Regulation

Differential regulator Controls the domestic load pump.

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

Used for storing hot water extracted from the biofuel boiler (max. 85°C). Compensates for any differences between heat production and needs. Solar use with DC / QUADRO

Maintains a reserve of domestic hot water for the household (e.g. shower) with an electric back-up for the summer. Solar use with LIGHT / DUO / TRIO

Optimally ensures the desired temperature on the premises and saves on fuel, whatever the outside temperature.
