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.
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.
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
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.
If the boiler and/or peripheral equipment are corroded by such
chloride or fluoride compounds, the contractual guarantee
Position the air inlets in relation to the high ventilation vents in order
that the air is refreshed throughout the boiler room.
1.2Forced flue versions (Not available in Germany)
- GTU120FF boilers are in compliance with the standard for fuel 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.
2Burner
Refer to the user instructions for the burner.
Z
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).
- They may be commissioned only using devices sold by De Dietrich
(particularly concentric flues, connecting parts, terminals).
- 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
blocked and the condensates will no longer be able to flow off and will
fill the flue gas discharge pipe causing the boiler to malfunction.
- Regularly check the level of water in the installation. Top it up, if
need be, avoiding the abrupt input of cold water into the hot boiler.
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.
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.
4. Control panel B / B2:
- Set the Summer/Winter swtich to
Control panel E / E1 / D:
