3 Installationinformation/Maintenanceinformation
3.1 Positioning/modications
- Your oil condensing boiler should only be installed and
modied by an approved heating contractor, as only they
have the essential knowledge to carry out such work.
- Flue gas components must not be modied.
- Never modify the drain or the safety valve.
Nevercloseorrestricttheventilationaperturesindoors
orwallswhenoperatingtheboilerinopenuemode;only
starttheboilerwhentheuehasbeenfullyinstalled.
Onlyoperatetheboilerinroomsealedmode,afterthe
roomsealedsystemhasbeenfullyinstalledandthewind
protectorisnotcoveredup.
Failuretocomplywiththisresultsinariskofpoisoningor

Pleasenotebeforecommissioning
4.1 Fillingthesystem
The heating system must be completely lled with water. If
necessary, top up with water. Shut-off valves must be open
when lling the heating system. The system pressure must be
1.5 to 2.5 bar. The connection required for lling the system
between the tap water and heating water must be removed after
lling has been completed. Otherwise there is a risk that your
tap water will be contaminated by heating water.
Inhibitorsarenotpermissible.Otherwisethereisariskof
damagetotheboiler.
4.2 Fillingthetrap
Thetrapmustbettedandlled.Otherwise,thereisarisk
ofuegasleaking,andthereforeariskofpoisoningand
suffocation.
4.3 Openingtheshut-offvalves
The shut-off valves for heating ow and return must be open.
4.4 Checkingthewaterlevel
Regularly check the water level. The pressure gauge must
indicate between 1.5 and 2.5 bar. Your heating contractor will
explain how to top up your system. Never add additives to your
heating water, otherwise components may be damaged.

Energysavingtips

6 Energysavingtips
6.1 Heatingmode
Savingenergywithcutting-edgeheatingtechnology:oilredcondensing
technologysavesyourcash.
Advanced condensing technology recovers the energy that, in non-condensing
appliances, is expelled unused to the atmosphere with the ue gas, and uses it for
heating.
Useaslittleelectricalenergyaspossible.
Operate your system with multi stage heating pumps at the lowest possible level. No
adjustment is usually necessary for modulating pumps, as the adjustment is carried
out automatically.
Regularservicingofyourheatingsystempaysforitself.
A contaminated burner or poorly adjusted boiler can reduce the heating system
efciency. Having your system serviced regularly by your local contractor quickly
pays for itself.
Heatingatthelowestenergylevel
Operate your heating system, where possible, with a return temperature of less than
45 °C, to achieve maximum utilisation of the condensing technology.
Aheatingsystemcontrolunitalsoregulatesyourheatingbills
A heating system in standby mode saves energy. An advanced, weather-
compensated or room temperature-dependent heating system control unit with
automatic night-time reduction and thermostatic valves ensures that the system only
operates when heat is actually required, saving money the rest of the time.
- Fit your heating system with a weather-compensated heating controller from the
Wolf range of accessories. Your heating contractor will be happy to advise you on
optimum settings.
- Use the night setback function in conjunction with Wolf control accessories to
match the energy level to the actual demand period.
- Use the summer setting.
Neveroverheatyourhome.
Regulate the room temperature as accurately as possible. This will allow occupants
to feel comfortable and will not waste energy on delivering heating output that nobody
needs. Identify the optimum temperature for different rooms, such as living rooms
and bedrooms.
A room temperature that is one degree higher than necessary causes an additional
energy consumption of approx. 6 %.
- Use room thermostats to match the room temperature to the actual use of the
room.
- In any room where you have installed a room temperature sensor, open the
thermostatic valve fully. This enables you to achieve optimum control of your
heating system.
Ensureadequateaircirculation
Air must be able to circulate freely near radiators and room temperature sensors,
otherwise the heating system will be less effective. Long curtains or poorly positioned
furniture can absorb up to 20% of heat.

Energysavingtips
11
3062548_201802
Keeptheheatinsidetheroom–atnighttoo!
At night, closing shutters and drawing curtains noticeably reduces heat losses via the
window areas. Thermally insulated radiator recesses and light coloured paintwork
can save up to 4% on your heating bills. Airtight joints at windows and doors also
help to keep energy inside the room.
Minimiseenergylossthroughsensibleventilation
Ventilation for hours loses the heat which is stored in walls and objects. As a result,
the room will only become comfortable again after prolonged heating. Short and
thorough airing is more effective and more pleasant.
Bleedingradiators
Regularly bleed radiators in every room. This ensures that radiators and thermostats
continue to operate properly, especially in upper oor apartments of apartment
buildings. The radiator will respond quickly to changing heat demands.
IntelligentuseofDHWcirculationpumps
Always control DHW circulation pumps with time switches. Program these in
accordance with your DHW demand patterns.
6.2 DHW mode
OptimumDHWtemperature
Only ever set the DHW temperature or that of the cylinder to the temperature you
really require. Any additional heating uses additional energy.
SensiblehandlingofDHW
Showering consumes only approximately 1/3 of the amount of water required for a
bath. Repair any dripping taps immediately.
6.3 Faults/Faultcodes
If the illuminated ring of the status indicator ashes red, where possible read the fault
code on the connected control unit accessory and note the code. The boiler can be
restarted by pressing the reset button. In case of repeated faults, switch OFF the
boiler and notify your heating contractor.
Oil condensing boilers are equipped with an electronic ue gas temperature limiter.
The system automatically shuts down when the ue gas temperature exceeds
110 °C. The boiler can be restarted by pressing the reset button. If this recurs, ask
your heating contractor to check the ue system.
Keepyouroperatinginstructionssafeinaneasilyaccessibleplacenearyour
oilcondensingboiler.
