2.1 Safety and warning information
When installing the systems, observe the general safety
instructions and warnings which appear before the instructions for each operation.
2.1.1 Classification of warnings
The warnings are classified according to the severity of the
potential danger using the following danger signs and signal words:
Danger sign Signal word Explanation
Immediate risk of death or
Danger!
a
Danger!
e
Warning.
a
Caution.
b
2.1 Meaning of danger signs and signal words
risk of severe personal
injury
Risk of death from electric
shock
Risk of minor personal
injury
Risk of material or environmental damage
Qualification of technical staff
The installation of the boiler and its flue must be carried
out by a competent person approved at the time by the
Health and Safety Executive.
> Furthermore, the requirements, rules and regulations
specified in the installation instructions for the appliances must be followed.
Risk of fatal poisoning from escaping flue gases
All openings in the flue ducting that can be opened for
inspection purposes must be closed before commissioning
and while the system is in operation.
> Make sure that the openings in the flue duct system are
only opened by a competent person.
Flue gas can escape from leaking pipes or damaged seals.
> When installing the flue system, use only flue pipes of
the same material.
Mineral oil-based lubricants may damage the seals.
> On no account should mineral-oil based grease be used
for installation.
> Only use water or commercially available soft soap, if
necessary, to assist with installation.
Mortar residues, shavings, etc. in the flue ducts can restrict
the outward flow of the flue gas. Flue gas may escape into
the room.
> After installation, remove all mortar residues, shavings,
etc. from the flue ducts.
Extensions that are not fixed to a 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 bracket. The distance between two
pipe brackets must not be greater than the length of the
extension.
2.1.2 Structure of warnings
Warnings signs are identified by an upper and lower separating line and are laid out according to the following basic
principle:
Signal word!
Type and source of danger!
a
2.2 General safety information
> Observe the following safety instructions and require-
ments at all times.
4 Installation Manual air/flue gas system for ecoTEC 834449_16
Explanation of the type and source of
danger.
> Measures for averting the danger.
Unsecured joints on the air/flue gas ducting may become
disconnected.
> Secure each air-pipe joint by screwing the air-pipe collars
with the air-pipe ends or the boiler flue connection.
Condensate that collects in a particular place can damage
the flue pipe seals.
> Install a horizontal flue pipe with a gradient of 3° 1°
sloping downwards to the appliance. That equates to a
drop of approx. 50 mm 20 mm per metre of pipe run.
Requirements for the air/flue pipe outlet
> Observe the requirements for the air/flue pipe outlet
specified in the installation instructions for the boiler.
Fire risk from lightning strike
> Make sure that the flue system is incorporated in the
building's lightning conductor circuit if the building has
one.

Risk of corrosion in the flue system
Sprays, solvents or cleaning agents, paints and adhesives
may contain substances which, if the boiler is operating
under the most unfavourable conditions, can cause corrosion in the flue system.
> Use only the appropriate Vaillant components when
installing the flue system.
> Keep the combustion air that is drawn into the boiler
free of chemicals that contain substances such as fluo-
rine, chlorine or sulphur.
Use of tools
Unsuitable tools and/or improper use of tools can cause
damage (e.g. to casing panels or system components).
Always use screwdrivers and spanners (open-ended) of the
correct size when undoing or tightening screws, nuts and
bolts. Do not use pipe wrenches, extensions, etc.
Distance from adjacent components
The air/flue pipe operates at a very low temperature, which
means that there is no minimum clearance required
between the air pipe and adjacent supply lines.
2.3 Regulations
Installation of the gas-fired wall-hung boiler and its air/flue
pipe must conform to the Gas Safety Regulations (Installation and Use) 1998, the Building Regulations and BS 5440
Part 1.
2.5 Certified air/flue gas systems
The Vaillant ecoTEC gas-fired wall-hung boilers are certified
in accordance with the EC Gas Appliance Directive 90/396/
EEC or 2009/142/EC as heating boiler systems with associated flue systems. This Installation Manual is a component
of the certification and is cited in the type approval certificate. Subject to compliance with the requirements for carrying out installation set out in this Installation Manual, the
usability of the air/flue pipe system products identified by
Vaillant article numbers is certified.
Danger!
Vaillant appliances are certified only for
a
use with genuine Vaillant flue pipes.
Malfunctions can occur if you use other
accessories. These may result in damage
and injury. You will find a list of genuine
flue pipes in the Vaillant installation manual
for flue pipes. The CE mark is valid only if
the appliance is operated with Vaillant flue
pipes.
> Only use genuine
Vaillant flue pipes.
2.4 Intended use
Vaillant air/flue pipe systems are constructed using stateof-the-art technology in accordance with recognised safety
regulations. Nevertheless, there is still a risk of injury or
death to the system operator 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 Vaillant air/flue pipe systems described in this manual
may only be used in conjunction with the appliance types
specified in this manual.
Any use other than or beyond that specified constitutes
improper use and nullifies any responsibility or liability
whatsoever on the part of the manufacturer/supplier for
resulting loss or damage. In such cases, the risk is borne
solely by the person carrying out the work and the
user.
Intended use includes the following:
– observing the operating, installation and maintenance
instructions supplied for the Vaillant product and any
other parts and components of the system
– installing and fitting the product in accordance with the
appliance and system approval
– complying with all of the inspection and maintenance
conditions listed in the instructions.

If you wish to install the air/flue pipe to the side of the
boiler, you can determine the position of the wall penetration by carefully transposing the centre line of the wall penetration marked on the mounting template (¬ fig. 3.8).
The position of the wall penetration must allow for installation of the flue pipe with a slight rise of roughly 3°1° (that
equates to 50 mm 20 mm per metre of pipe length).
> Calculate the required rise according to the length of the
flue pipe and then mark the position for the wall penetration.
> If possible drill the hole in the wall with a core drill, diam-
eter 125 mm.
If the desired position for the wall penetration is
accessible from the outside of the building, you
i
can drill the hole with a 107 mm diameter core
drill and insert the external wall seal from the
outside of the building.

3.7 Fitting the variable terminal kit ( VTK)
Minimum clearances for flue terminal
The minimum clearances for the flue terminal as defined in
BS 5440 must be observed unless the boiler manufacturer
is permitted to use smaller clearances that are not considered safety-critical.
Vaillant has reduced the minimum clearances for the flue
terminal and specifies them in the boiler installation
instructions. Those clearances are minimum distances applicable to all types of installation except to installation of the
variable terminal kit (VTK).
If a VTK is connected to a horizontal flue pipe, the terminal
clearances for the air inlet are smaller. The terminal clearances for the "new" flue outlet at the end of the VTK are
unchanged.

For the VTK, the minimum clearance of air inlets A, B and C
from openings such as a window have been reduced to
150 mm. That means that the terminal on the horizontal
flue pipe becomes an air inlet when a VTK is connected and
thus can be installed at a distance of less than 300 mm
from a window opening or ventilation brick.

The boiler flue connection is attached to the boiler by a
bayonet fitting.
> Insert a screwdriver of a suitable size into the slot
between the testing ports.
> Carefully press the screwdriver downwards to release the
boiler flue connection from the catch.
> Turn the boiler flue connection anticlockwise as far as
the stop and then remove it by pulling it upwards.

4.4 Fitting the sliding sleeve
If there is sufficient space available, you can use
a sliding sleeve (art. no. 303215) to connect the
i
flue pipe to the boiler flue connection. This consists of a sliding sleeve for the inner flue and an
over centred clip for the outer air duct which
can facilitate easy disconnection of the boiler
from the flue system.
When using the sliding sleeve, you must shorten
the last extension pipe by an additional 85 mm.

> Drill two holes 3 mm in diameter through the air-pipe
collar and the air pipe. The hole centres should be 6 mm
from the edge of the air-pipe collar.

supplied.

> Install the horizontal flue pipe with a gra-
dient of 3° 1° sloping downwards to the
appliance. That equates to a drop of
approx. 50 mm 20 mm per metre of
pipe run.
The air/flue pipes of the horizontal wall penetra-
tion are not concentric. With the wall penetration fitted horizontally, the flue pipe slopes
downwards at 1.5° towards the inside.

4.5 Fitting the sliding sleeve
> Slide the sliding sleeve (1) onto the extension flue pipe
(2) as far as the stop.
> Push the sliding sleeve back until it locates into the
socket (3) of the boiler flue pipe (4).
> Make sure that both ends of the sliding sleeve overlap
the flue pipes by at least 20 mm.
> Fit the air-pipe collar (7) around the air pipes (5 and 6).
> Close the catch on the air-pipe collar.

the seals. The seals should therefore not be
lubricated.
> Only use water or commercially available
soft soap, if necessary, to assist with
installation.
> Do not fit any damaged seals.
> When fitting the pipes, make absolutely
sure the seals are correctly seated.
> File off sharp burrs and chamfer the
ends of the pipes before assembling
them so that the seals are not damaged,
and dispose of the shavings.
> Do not fit any pipes that are dented or
damaged in any other way.
Danger!
Risk of poisoning due to escaping flue
gas.
> Secure the flue pipe with the bracket so
that it is correctly centred relative to the
air pipe.
