8 Inspection and maintenance

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

necessary, 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.

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.

8.1.1 General inspection and maintenance

instructions

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

series status only genuine Vaillant spare parts must be

used when carrying out inspection, maintenance and

repair work.

For an overview of the available original Vaillant spare

parts, contact the Vaillant sales office on

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.

- Visual, the integrity of the boiler combustion circuit

and relevant seals.

- The gas inlet working pressure at maximum rate as

described in Section 6.2.3.
