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.

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).

Check the seal on the gas and water pipe connections.

Check that the appliance is correctly regulated for the type

of combustible used.

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

neutral (N) and earth 4.

To guarantee protection against the corrosion of domestic

hot water calorifiers fitted with a titanium anode (Titan

Active System® protection system), always leave the

control panel switched on. To switch off the heating or the

domestic hot water, use the Summer or Antifreeze mode.

1 Aeration

Warning:

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.

1.1 Chimney versions - Chimney condensation versions

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).

1.2 Forced flue versions (Not available in Germany)

- GTU 120 FF boilersare incompliancewiththe standardforfuel oil

boilers type C (XPD 35-430). They can be installed in all kinds of

premises whatever their volume, even if they do not include a

window or framed opening.

- TheymaybecommissionedonlyusingdevicessoldbyDeDietrich

(particularly concentric flues, connecting parts, terminals).

3 Maintenance

- The servicing and cleaning of the boiler and the sweeping of the

flue gas pipe and the bleed pot must be done at least once a year

by a qualified professional.

-Oil-fired condensation boiler: The condenser and the

condensates neutralisation station must serviced at least once a

year by a qualified professional.

To ensure safe operation of the boiler: The siphon and the

condensates evacuation conduit must imperatively be

checked and cleaned at least once a year.

Without an annual service, the siphon is in danger of becoming

blockedandthecondensateswillnolongerbeabletoflowoffandwill

fill the flue gas discharge pipe causing the boiler to malfunction.

- Regularly check the level of water in the installation. Top it up, if

needbe,avoidingtheabruptinputofcoldwaterintothehotboiler.

If this operation is repeated several times per season, locate the

leak and repair it.

- We recommend taking out a maintenance contract.

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

necessity.

For example: Several months' absence with the risk of ice

in the building.

Commissionning

Initial commissioning must be done by a qualified

professional.

1. Check the water pressure in the installation. Top up with more

water if necessary.

2. If using an oil-fired boiler, check the oil level in the tank.

3. Open the fuel oil inlet or the gas valve.

4. Control panel B / B2:

- Set the Summer/Winter swtich to

Control panel E / E1 / D:

-Setswitch

AUTO/

to the

AUTO

position.

5. Set the On/Off switch to 8.

Stopping the boiler

Set the On/Off switch to 7.

On the Off position 7, the domestic hot water calorifier

fitted with a titanium anode is not protected against

corrosion.

Precautions to take if there is a danger of frost

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.

- Closethe dooroftheboilertopreventtheinternalcirculationof air. - Removethepipeconnectingtheboilertothechimneyandplugthe

nozzle.

Troubleshooting

Checks to make before calling your fitter:

The burner will not start.

ZRefer to the user instructions for the burner.

The burner is operating but the radiators are cold.

- Bleed the radiators.

- Top up the primary circuit with water.

- Check that the heating pump is operating correctly.

- Ifitisoftennecessary to top up the installation with water, contact

your fitter.

Before informing the fitter of a fault, make a note of the following

information:

- Product type

- Serial number

- Type of combustible

This information can be found on the rating plate stuck to the

side panel of the boiler.
