1 Safety
1.1 Action-related warnings
Classification of action-related warnings The action-related warnings are classified in accordance with the severity of the possible danger using the following warning symbols and signal words:
Warning symbols and signal words Danger! Imminent danger to life or risk of severe personal injury
Danger! Risk of death from electric shock
Warning. Risk of minor personal injury
Caution. Risk of material or environmental damage
1.2 Intended use
The air/flue pipes described here are constructed using state-of-the-art technology in accordance with the recognised safety rules and regulations. Nevertheless, there is still a risk of injury or death to the system’s end user or others or of damage to the products and other property in the event of improper use or use for which the products are not intended.
The air/flue pipes mentioned in these instructions must only be used in conjunction with the product types mentioned in these instructions.
Any other use that is not specified in these instructions, or use beyond that specified in this document, shall be considered improper use.
Intended use includes the following:
­ observance of accompanying operating, installation and maintenance instructions for all system components
­ installing and setting up the product in accordance with the product and system approval
­ compliance with all inspection and maintenance conditions listed in the instructions.

1.3 General safety information
1.3.1 Risk caused by inadequate qualifications
The following work must only be carried out by competent persons who are sufficiently qualified to do so:
­ Set-up ­ Dismantling ­ Installation ­ Start-up ­ Inspection and maintenance ­ Repair ­ Decommissioning
Proceed in accordance with current technology.
1.3.2 Risk of poisoning due to escaping flue gas
Improperly installed flue pipework may cause flue gas to escape.
Before starting up the product, check that the whole air/flue pipe is securely fastened and check it for tightness.
The flue pipework may become damaged by unforeseeable external influences.
As part of the annual maintenance, inspect the flue system in terms of: ­ external faults such as brittleness and damage ­ safe pipe connections and secure fastenings
1.3.3 Risk of death from escaping flue gas
Ensure that all openings in the air/flue pipe that are within the building and can be opened are always closed for start-up and during operation.
Flue gas may escape from leaking pipes or damaged seals. Mineral-oil-based greases can damage the seals.
When installing the flue system, use only flue pipes of the same material.
Do not install any damaged pipes. File off sharp burrs and chamfer the ends
of the pipes before installing them, and dispose of the shavings. Never use mineral-oil-based grease for the installation.

3

To facilitate the installation, use only water, standard commercial soft soap or, if required, the enclosed lubricant.
Mortar residues, shavings, etc., in the flue gas route may restrict the outward flow of the flue gas, meaning that flue gas can escape.

can be guaranteed that the air supply is sufficient.
For mutual interlocking of the fan and the product, install the Vaillant accessory VR 40 multi-functional module (article number 0020017744).

After installation, remove all mortar residues, shavings, etc., from the air/flue pipe.
Extensions that are not fixed to the wall or ceiling may become disconnected due to sagging or thermal expansion.
Ensure that every extension is fixed to the wall or ceiling by means of a pipe clamp. The distance between two pipe clamps must not be greater than the length of the extension.

1.3.5 Risk of fire and damage to electronics caused by lightning
If the building is equipped with a lightning protection system, incorporate the air/flue pipe into the lightning protection.
If the flue pipework (parts of the air/flue pipe situated outside the building) contains metal materials, incorporate it into the potential equalisation system.
1.3.6 Risk of injury from ice formation

Condensate that collects inside the flue in certain areas can damage the flue pipework seals.
Route the horizontal flue pipe to the product with a downward gradient. ­ Downward gradient to the product: 3° ­ 3° corresponds to a downward gradient of approx. 50 mm per metre of pipe length.
Sharp edges in the shaft may damage the flexible flue gas duct.
Two people are needed to guide the flue pipework through the shaft.
Never attempt to pull the flexible flue gas duct through the shaft without using the installation aid.

Where air/flue pipes penetrate the roof, the water vapour contained in flue gas may precipitate as ice on the roof or the roof structures.
Ensure that this ice formation does not slide from the roof.
1.3.7 Risk of corrosion caused by sooted chimneys
Chimneys that previously discharged the flue gas from oil- or solid-fuel-fired heat generators are unsuitable for combustion air supply. Chemical deposits in the chimney may pollute the combustion air and cause corrosion in the product.
Ensure that the combustion air supply is free from corrosive materials.

1.3.4 Risk of death from escaping flue gas due to negative pressure
For open-flued operation, the product must not be placed in rooms from which the air is extracted using fans (e.g. ventilation systems, extraction hoods, tumble dryer ventilation). These systems create negative pressure in the room. This negative pressure can, for example, cause flue gas to be sucked into the installation room from the terminal through the annular gap between the flue pipework and the shaft or from a multi-configuration flue system through a heat generator that is not in operation. The product must only be operated open-flued if simultaneous operation of the product and fan is not possible or it

1.3.8 Moisture damage caused by incorrect installation position of the inspection elbow
An incorrect installation position leads to condensate leaking from the inspection-opening cover and may lead to corrosion damage.

2 Smoke gas

Extremely damp extract air escapes from the channel vents. This may condense in the air pipe and cause damage to the product.
Observe the requirements for minimum clearances in accordance with the figure.
1.3.10 Risk of material damage caused by flue gases or dirt particles that have been sucked in
If the terminal for the air/flue system is adjacent to a chimney, flue gases or dirt particles may then be sucked in. Sucked-in flue gases or dirt particles may damage the product.
If the adjacent chimney feeds flue gas with an extremely high temperature or soot starts to burn, the terminal for the air/flue system may be damaged by the heat effect.
Take suitable measures to protect the air/flue system by raising the chimney, for example.

The height of the attachment depends on the diameter of the other flue system and must be determined in accordance with the illustration.
If the other flue system cannot be raised, you must operate the product as an open-flued system.
Note Attachments for raising flue systems are available from various chimney sweep companies.
If the adjacent flue system has to be resistant to soot fires, the terminal for the flue pipework may become damaged by the heat effect of the adjacent chimney (chimneys are flue systems that are resistant to soot fires and suitable for solid-fuel fireplaces).
The terminal must then be designed based on the following three versions. In doing so, the thickness of the wall between the shafts must be at least 115 mm.

1.4 UKCA/CE certification
The heat generators are certified as gas-fired boilers with associated flue systems in accordance with the Gas Appliances Regulation (EU) 2016/426. This set-up instructions are a component of the certification and are cited in the type test certificate. In compliance with the regulatory statutes of these setup instructions, the proof of usability of the elements identified by Vaillant article numbers that are designed for the air/flue pipe is provided. If you do not use certified Vaillant air/flue pipe elements when installing the heat generators, this voids the UKCA/CE conformity of the heat generator. We therefore strongly recommend that you fit Vaillant air/flue systems.

5.3 Technical properties of the air/flue systems from Vaillant for condensing products
The air/flue systems from Vaillant have the following technical properties:

Technical feature Temperature resistance
Leak-tightness Condensate resistance Corrosion resistance Clearance from combustible materials
Installation site Resistance to fire
Fire resistance duration

Description
Adapted to the maximum flue gas temperature of the product. The limit value of the flue gas temperature is 125 °C.
Adapted to the product for use in buildings and outdoors
For gas and oil fuels
Adapted to the gas and oil condensing boiler
­ Concentric air/flue pipework: No clearance required
­ Non-concentric flue pipework: 5 cm
In accordance with the installation instructions
Normal level of flame resistance (in accordance with EN 13501-1 Class E)
None: The external pipes of the concentric system are not flammable. A required fire resistance duration is provided by shafts within the building.

5.5 Route of the air/flue pipe in buildings
The air/flue pipe should be as short as possible and run as straight as possible.
Do not install several elbows or inspection elements im-
mediately after each other.
As a result of standards relating to the hygiene of potable water, potable water lines must be protected against impermissible heating.
Lay the air/flue pipe separately from the potable water
lines.
It must be possible to check and, if required, clean the entire length of the flue gas route.
It should be possible to remove the air/flue pipe again with a minimal amount of effort (preferably no time-consuming mortising work in the living area, but screwed-in casing instead). If they are arranged in shafts, they are usually easy to remove.
5.6 Location of the terminal
The location of the flue system terminal must comply with the relevant applicable international, national and/or local regulations.
Align the terminal of the flue system in such a way that
ensures a secure outward flow and distribution of the flue gases and prevents these gases from re-entering the building through openings (windows, supply air openings and balconies).
Observe the existing regulations with regard to the clear-
ances to windows and ventilation openings.

5.4 Requirements for the shaft for the air/flue pipe
Air/flue pipes from Vaillant do not have any fire resistance (direction of operation from the outside to the inside).
If the air/flue pipe is guided through parts of a building that require a level of fire resistance, a shaft must be installed. The shaft must ensure the fire resistance (direction of operation from the outside to the inside) that is required for the building parts through which the flue system is guided. The required fire resistance must demonstrate a suitable classification (brick partition and heat insulation) and be sufficient for the building’s requirements.
Observe the national ordinances, regulations and standards.
An existing chimney that was used for the flue system usually meets these requirements and can be used as a shaft for the air/flue pipe.
The gas tightness of the shaft must comply with the test pressure class N2 in accordance with EN 1443. An existing chimney that was used for the flue system usually meets these requirements and can be used as a shaft for the air pipe.
If the shaft is used for combustion air supply, this must be designed and, in particular, insulated in such a way that no moisture (caused by the cooling of the shaft by cold combustion air penetrating from the outside) can penetrate the exterior of the shaft.An existing chimney that was used for the flue system usually meets these requirements and can be used as a shaft for combustion air supply without the need for additional heat insulation.

5.7 Disposing of condensate
Local regulations may stipulate the minimum quality of any condensate that may enter the public waste-water system. If required, a condensate neutraliser must be used.
When disposing of the condensate into the public waste-
water system, observe the local regulations.
Only use corrosion-resistant piping material for removing
condensate discharge.
6 Set-up
6.1 Preparing for set-up and installation
6.1.1 Clearance between combustible materials and the components
For concentric air/flue pipework, it is not necessary to leave any clearance between the air/flue pipe or the corresponding extension and components made from combustible materials, because, at the nominal heat output of the product, components adjacent to the surface cannot reach temperatures higher than 85 °C.

4. If required, shorten the mounting rail (2). 5. Secure the support elbow (1) on the mounting rail in
such a way that, after installation, the flue pipework is arranged in the centre of the shaft.

Use a line (2) to lower the first flue pipe (3) down far enough until you can insert the next flue pipe (1).
In distances of max. 5 m, slide a spacer (4) onto each of the flue pipes.
­ Do not install any spacers in shafts with a diameter between 113 mm and 120 mm or with a side length between 100 mm and 110 mm.
If you have inserted an inspection opening in the rigid flue pipework, install one spacer behind and one in front of the inspection opening.
Continue joining the pipes together repeatedly until you can insert the lowest pipe into the support elbow and the uppermost pipe permits the installation of the shaft top.
­ The sleeve side of the flue pipe must always point upwards.
Remove the line from the shaft.
Install the plastic (PP) shaft top. ( Page 26)
Alternatives :

Air/flue pipe installation manual 0020261391_03

6.5 Installing the vertical roof duct 6.5.1 Installation instructions
Danger! Risk of poisoning due to escaping flue gas and risk of material damage due to the roof duct shearing off. Snow and ice sliding down pitched roofs may break off the vertical roof duct where it exits the roof.
In regions where heavy snow
falls/extensive ice formation can be expected, install the vertical roof duct close to the ridge or install a snow guard mesh above the roof duct.
The vertical roof ducts can be shortened under the roof. However, to ensure that the fixing bracket is secured tightly, the lengths must still be sufficient.
Shorten the flue pipe and the air pipe by the same
amount.

In doing so, note that the air/flue pipe
must be centred in the wall hole.
Determine the installation site for the air/flue pipe. When installing the product near a light source, point out
to the end user that they must clean the terminal regularly. Otherwise, due to the insects that the light may attract, the terminal may become dirty.

6.8.2 Installing a connection to the air/flue system
Caution. Risk of damage to the product.
There must not be any excess pressure in the vertical part of the flue system, because, in this case, the burner may pulse and the product may become damaged. The product is not suitable for this mode of operation and has not been checked.
Provide evidence of the functional reliab-
ility of the vertical flue pipework in accordance with EN-13384 using the specifications for flue gas temperature and flue gas mass flow rate from the installation instructions for the product.

Caution. Risk of damage to the structure of the building.
The static function and fire-protective function of the shaft wall may be impaired by fastenings.
Do not attach any fastenings using
screws, wall plugs, etc. directly to the shaft wall of the air/flue system.
Do not attach fastenings to primary
walling or sideways to the wall.

1. Detach the sleeve on the flue pipe so that you can slide the flue pipe into the seal.
2. When shortening the air pipe, ensure that you do not cut the end with the spacer.
3. Clamp the supplied fixing clamp around the flue pipe. ­ The fixing clamp must support the flue pipe after it is inserted into the air/flue system’s flue sleeve on the spacer for the air pipe. This prevents it from sliding into the flue gas duct.
6.8.4 Installing a connection to a metal air/flue system
Note Metal air/flue systems feature cylindrical supports on the flue-gas-side.
1. Insert the concentric flue pipe with sleeve. 2. Ensure that, during the installation, the flue pipe is
locked using the spacer in the air pipe. You do not require the pipe clamp for this. 3. For metal air/flue systems that have no sleeves, you must secure the air pipe using mortar and seal the shaft.
