to the system user or operator.
1.3 Instructingthesystemuser
- Instruct the system user to take out an inspection and maintenance contract with
an approved contractor.
- Inform the system use that the annual inspection and maintenance may only be
performed by an approved contractor.
- Inform the system use that repair work may only be performed by an approved
contractor.
- Inform the system user that only original spare parts may be used.

1.4 Applicabilityoftheseinstructions
These installation instructions apply to CGB-75/100 gas condensing boilers.
1.5 Acceptance
Within four weeks of commissioning of the burner the operator must notify the local
flue gas inspector accordingly. According to the Bundes-KÜO (German Federal
Sweeping and Inspection Act), tests and inspections are only required every 3 years
[Germany].
1.6 Recyclinganddisposal
- Old equipment may only be disconnected from the gas and electricity supply by a
qualiedcontractor.
- Always dispose of materials according to environmental, recycling and waste man-
agement standards.
- Old appliances, wearing parts, defective components and environmentally hazard-
ous liquids and oils must be disposed of or recycled according to applicable waste
disposal regulations without harming the environment.
Theymustnotbedisposedofashouseholdwaste.
- Disposeofpackagingmadeofcardboard,recyclableplasticsandsyntheticller
materials in an environmentally compatible manner through appropriate recycling
systems or a recycling centre.

Workingonthesystem
- Close the gas shut-off valve and secure it against uninten-
tional reopening.
- Isolate the system from the power supply (e.g. by remov-
ing a separate mains fuse or by means of a main switch
or a heating emergency stop switch) and check to ensure
there is no voltage.
- Safeguard the system against reconnection.
Inspectionandservice
- Ensure the correct operation of the gas boiler by having a
contractor carry out inspections at least once a year and
maintenance/repair when required.
- (DVGW - TRGI 2008 - G600).
We recommend arranging a suitable maintenance con-
tract.
- The operator is responsible for the safety, environmental
compatibility and energy quality of the heating system
(German Immission Control Act/Energy Saving Ordi-
nance) [Germany].
- Use only genuine WOLF spare parts.

7. Sitinginstructions
Sound insulation: Under certain critical installation conditions
(e.g. installation on a drywall), additional measures may be
necessary to soundproof the boiler. In such conditions, use
anti-vibration rawl plugs and, if necessary, rubber mounts or
insulation strips.

Electrical connection must be made on site.
Please maintain the 350 mm clearance to the ceiling to enable
inspection and maintenance work on the boiler to be carried
out, otherwise the necessary inspection and function tests
on components cannot be ensured during maintenance. The
drain hoses must be secured with the retainer above the drain
outlet (trap). The drain must be able to be easily inspected.

gauge (on site) must indicate between 1.5 and 2.5 bar
- Check the entire system for water leaks
- Open the air vent valve
- Start the condensing boiler, set the heating water temperature

20.Adjustingthemodulatingpump(accessory)
Inheatingmode:
The heating circuit pump (accessory) modulates in proportion to the burner output. This means at maximum burner output, the
pump operates at the maximum pump speed for heating mode. At minimum burner output, the pump operates at the minimum
pump speed for heating mode. In other words, the burner output and pump speed are regulated subject to the required heat load.
Modulating the pump reduces the power consumption.
In DHW mode:
The heating circuit pump will not modulate, but operates constantly at the selected pump speed.
Instandbymode:
The heating circuit pump will not modulate, but operates constantly at the selected pump speed.
Standby mode 20%

The speed limits for heating mode can be changed with the BM programming unit.

proximity to the boiler.
Thellandtop-upwatermustonlybetreatedwithadesalina-

mum permissible total hardness" table shows the degree to
which water treatment is required. The system water must not
fallbelowatotalhardnessof2°dH,whichcorrespondstocon-
ductivityof≈60μS/cm.Themax.permissibletotalhardness
andthecorrespondingmax.conductivityaresystem-specic
and must be calculated (see also "Maximum permissible

<=30 μS/cm) must not be mixed with untreated DHW. The
addition of chemicals or de-scaling using single stage ion
exchangers is not permissible, as system damage with asso-
ciated water leaks may occur.
We recommend regular emptying of the sludge lter and
keeping of a system log.
Permissible methods:
- Desalination using mixed-bed cartridges. These are multi
stage ion exchangers. We recommend, for example, using
e.g.GrünbeckorJudocartridgesfortherstll,andlater
as and when required.
- Desalination via reverse osmosis
- Topping up with distilled water

Example:
Systemoutput=170kW;
system volume VSystem=4000l;
Volume of top-up water
VTop-up =1000l
Total hardness of drinking water CDHW=18.5°dH;
Maximum permissible total hardness Cmax=8.4°dH
Systemoutput=170kW;
system volume VSystem=4.000l;
Volume of top-up water VTop-up=1000l
VAspec=4000l/170kW=23.53l/kW
Total hardness of drinking water CDHW=18.5°dH;
Maximum permissible total hardness Cmax=8.4°dH
Proportionofllingwatertobetreated:
A=100%-[(8.4-0.1)/(18.5–0.1)]x100%=54.9%
54.9%ofthellingandtop-upwatermustbedesalinated.
VTreatment=54.9%x(4.000l+1.000l)=2.746l
Whenllingthesystem,2,745lofdesalinatedwatermust
be added. The system can then be topped up to V max with
drinking water.
When topping up, it is important to check regularly that the
permissible total hardness is not exceeded.

Example:
System with a 170 kW boiler;
system volume VSystem=4000l;
VA,specic=4000l/170kW=23.5l/kW
This is greater than 10 l/kW, therefore stage 3 must be se-
lectedinsteadofstage2.Thellandtop-upwatermustbe
in the range of .2 to 8.4 °dH
If the total hardness of the untreated drinking water is too high,
someofthellandtop-upwatermustbedesalinated.
A% desalinated water should be added:
A=100%–[(Cmax–0.1°dH)/(CDHW–0.1°dH)]x100%
Cmax maximumpermissibletotalhardnessin°dH
CDrinking water total hardness of the untreated drinking water
in°dH
We recommend allowing for the expected top-up water during
therstll.Untreateddrinkingwatercanthenbeaddedlater.
VTreatment=Ax(VSystem + VTop-up)
In large systems in stage 4, the top-up water should not be
takenintoaccountduringtherstll.
