8.1
Inspection and maintenance intervals
a
Danger!
Risk of injury and risk of damage to property
due to neglected maintenance!
Neglected maintenance works or not observing
the demanded maintenance intervals can inter-
fere with the operational safety of the boiler
and can result in damage to property and to
persons.
Point out to the operator that he must observe
the annual maintenance intervals as a mini-
mum.
a
Danger!
Danger of life and limb due to improper mainte-
nance!
Maintenance work carried out improperly can
result in leakages and explosion.
The boiler may only be maintained by a compe-
tent person.
All service work must be carried out by a competent
person in accordance with the Gas safety, installation
and use regulations. In the UK this is considered to be a
person approved at the time by the Health and Safety
Executive.
In addition BS 6644: 2008“Specification for installation
of gas-fired hot water boilers of rated inputs between
70 kW net and 1.8 MW (net) (2nd and 2rd family gases”
advises that:
- The person carrying out a combustion measurement
must be assessed as competent in the use of a flue
gas analyser and the interpretation of the results.
- The flue gas analyser used must be one meeting the
requirements of BS7927 or BS-EN50379-3 and be
calibrated in accordance with the analyser manufac-
turers’ requirements.
- Competence can be demonstrated by satisfactory
completion of the relevant ACS standard assess-
ment, which covers the use of electronic portable
flue gas analysers’ in accordance with BS 7967,
parts 1 to 4.
- The flue gas analyser is set to the correct fuel set-
ting.
We recommend the conclusion of a maintenance con-
tract with an approved company or installer.
Maintenance is required in order to eliminate any devia-
tions of the actual condition from the specified condi-
tion. This normally is done by cleaning, adjustment and,
if necessary, replacing individual components that are
subject to wear.
You must carry out an annual maintenance of the Vail-
lant ecoCRAFT/3.
The heating engineer must perform all maintenance
work in the order specified in table 8.2.
a
Danger!
Possible poisoning and burning by escaping hot
flue gases
It is possible that hot flue gases escape and could result
in poisoning or burning, if the boiler is operated
- without a completely installed flue gas duct
- with an opened flue gas duct
- with internal leakages.
Operate the boiler
- for commissioning
- for testing purposes
- in continuous mode
only with completely mounted and closed flue gas duct.
8.2
General inspection and maintenance instruc-
tions
To ensure the faultless operation, long term availability
of all functions and long working life of your Vaillant
boiler and to prevent modifications to the approved se-
ries status only genuine Vaillant spare parts must be
used when carrying out maintenance and repair work.
For an overview of the available original Vaillant spare
parts, please contact the Vaillant sales office on
01634 292310.
During any maintenance or after change of parts of the
combustion circuit, the following must be checked:
- The appliance has been installed in accordance with
the relevant installation instructions.
- The integrity of the flue gas installation and flue
seals is in accordance with the relevant flue installa-
tion instructions enclosed.
- Visual, the integrity of the boiler combustion circuit
and relevant seals.
- The gas inlet working pressure at maximum rate as
described in 6.5.2.
- The gas flow rates as described in 6.5.3.
- Correctness of electrical, water and gas connec-
tions.
- Correctness of the water pressure.
- The condition of the whole system, in particular the
condition of radiator valves, evidence of leakage
from the heating system and dripping taps.
• Correct any faults before proceeding.
