8.1
Inspection and maintenance intervals
Danger!
Risk of injury and risk of damage to property
due to neglected inspection and maintenance!
Neglected inspection and maintenance works or
not observing the stated inspection and
maintenance intervals can interfere 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 demanded inspection and
maintenance intervals as a minimum.
• Carry out proper regular inspections once a
year.
• Carry out regular maintenance as dictated by
findings during the inspection process.
The frequency of maintenance must not be
longer than every 5 years.
Danger!
Danger of life and limb due to improper
inspection/maintenance!
Inspections/Maintenance work carried out
improperly can result in leakages and explosion.
• The boiler may only be inspected/maintained
by a competent 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 6798: 2009 “Specification for installation
and maintenance of gas-fired boilers of rated input not
exceeding 70 kW net” 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
manufacturers’ requirements.
- Competence can be demonstrated by satisfactory
completion of the relevant ACS standard assessment,
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 setting.
We recommend the conclusion of an inspection and
maintenance contract with an approved company or installer.
The inspection serves to determine the actual condition of the
respective boiler and compare it with the specified condition.
This is done by measuring, checking and observing.
Maintenance is required in order to eliminate any deviations
of the actual condition from the specified condition.
This normally is done by cleaning, adjustment and, if
neces-sary, replacing individual components that are subject
to wear.
You must carry out an annual inspection of the
Vaillant ecoTEC.
It is possible to perform a quick, accurate inspection
without removing components by requesting data from
the DIA system, carrying out the simple visual checks
indicated in Table 8.2 and performing a flue gas
measurement.
The maintenance intervals (at least once every 5 years)
and their scope are determined by the heating engineer
based on the condition of the boiler found during the
inspection.
All inspection and maintenance work should be performed in
the order specified in Table 8.2.
d
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 air/flue gas
duct
- with an opened air/flue gas duct
- with internal leakages and an opened front
casing.
• Operate the boiler
- for commissioning
- for testing purposes
- in continuous mode
only with closed front casing and completely
mounted and closed air/flue gas duct.

> If you require spare parts for maintenance or repair
work, use only Vaillant genuine spare parts .
During any inspection and 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 installation
instructions enclosed.
