Important information
The
EKEVO 6/N6-EKEVO 9/N9 G-E/
G-EU2/G-EU2N/G-EU3/G-EF3
burners
are designed for burning natural gas
(EKEVO 6-7 option for propane gas). The
design and function of the burners
comply with standard EN676. They are
intended for equipping systems that allow
burners to be used in accordance with
EN 676. Special burner components are
required in order to use the burner on
heat generators in accordance with the
Pressure Equipment Directive 97/23/EC
(not a constituent of the standard
equipment). Before using the burner with
equipment of this type, the equipment
characteristics must be checked. Burners
that comply with Pressure Equipment
Directive 97/23/EU come with a
declaration of conformity to this effect
and are labelled on the identification
plate. Any other type of application
requires the approval of ELCO. The
burner may only be used in accordance
with the instructions set out in this
documentation and the relevant technical
data. If not used properly, it could cause
damage to property and the environment
and personal injury. Furthermore, the
burner would no longer be CE-compliant.
Installation, commissioning and
maintenance must only be carried out by
authorised specialists and, during these
operations, all applicable directives and
regulations must be complied with. The
burners designed to run on propane do
not currently have any CE approval and
therefore require individual on-site
approval.
Burner description
Burners EKEVO 6/N6-EKEVO 9/N9
G-E/G-EU2/G-EU2N/G-EU3/G-EF3 are
electronically modulating, fully automatic
monoblock burners. The special design
of the burner head provides highly
efficient, low-polluting combustion. In
accordance with the certification as per
EN676 (versions in natural gas mode
only), the values obtained must respect
emission class 2 for EKEVO 6/N6-
EKEVO 9/N9 G-E, and class 3 for
EKEVO 6/N6-EKEVO 9/N9 G-EU2/G-
EU2N/G-EU3/G-EF3. Emissions rates
may differ, depending on combustion
chamber geometry, combustion chamber
load and the firing system (three-pass
boilers, boilers with reverse firing). For
specifying warranty values, the
conditions for the measuring equipment,
tolerances and humidity must be
observed.
Scope of delivery
The burner is supplied in three packaging
units:
- Burner with:
- integrated switch cabinet
- flange seal and securing screws
- operating instructions, circuit
diagram and spare parts list
- Burner head
- Compact gas train with gas filter
Before commissioning, a check must be
carried out to ensure that the product
delivered fully complies with the scope of
delivery.
The following standards should be
observed in order to ensure safe,
environmentally sound and energy-
efficient operation:
EN 226
Connection of atomising oil and gas
burners with fan to the heat generator
EN 60335-1, -2-102
Safety of electrical equipment for
domestic use
DIN EN 60204-1
Safety of machinery. Electrical
equipment of machines
DIN EN 50156-1
Electrical equipment for firing systems
Gas lines
When routing the gas lines and fittings,
the general installation instructions and
guidelines, as well as the following
national regulations, must be observed:
CH: - SVGW-Gasleitsätze G1
- Vorschriften der kantonalen
Instanzen (SVGW Gas Direc-
tives G1 - Regulations of the
Cantonal authorities) (e.g. fire
authority regulations)
DE: - DVGW-TVR/TRGI
Installation location
The burner must not be operated in
rooms with aggressive vapours (e.g. hair
spray, tetrachlorethylene, carbon
tetrachloride), high levels of dust or high
air humidity (e.g. laundry rooms). The
limitations of use set out in the technical
data must be observed.
Adequate provision must be made for the
supply of combustion air. Given standard
conditions, the combustion air
requirement may be calculated as
follows:
Vl [Nm³/h] = QF [kW] *1.25 [Nm³/(h*kW)]
We can accept no warranty for loss,
damage or injury caused by any of the
following reasons:
- inappropriate use
- incorrect installation and/or repair on
the part of the buyer or any third party,
including the fitting of non-original parts
Final delivery and instructions for use
The firing system fitter must supply the
operator of the system with operating and
maintenance instructions on or before
final delivery. These instructions should
be displayed in a prominent location at
the point of installation of the heat
generator. They should include the
address and telephone number of the
nearest customer service centre.
Notes for the operator
The system should be inspected by a
specialist at least once a year. It is
advisable to take out a maintenance
contract to guarantee regular servicing.
Please note:
When in operation, the burner produces
an electromagnetic field. In certain
circumstances, this field could affect
medical implants (e.g. pacemakers).
Before working with the machine, anyone
who has a medical implant should consult
their doctor and the manufacturer of the
medical implant in order to reduce the
risk of serious or fatal injury.
Attention:
During operation the burners produce an
electromagnetic field that may, under
certain circumstances, cause medical
implants (e.g. pacemakers) to
deteriorate. In order to minimise any risk
of serious or fatal injury, anyone who has
a medical implant should seek medical
advice and ask the implant manufacturer
before approaching their workplace.
Transport \ packaging \ storage
Safety measures
The burner and accessories must be
transported and stored using suitable
lifting equipment, means of transport and
tools. The safety instructions must be
complied with.
Transportation
Depending on the size and weight of
packaging, burners and accessories
must be transported manually or with the
use of suitable aids. The transport
instructions on the packaging must be
complied with. The burner must be
properly secured for transport. If
measures to secure the burner have not
been taken at the factory, suitable
measures to secure it during
transportation must be taken.
Packaging
The burner and accessories are packed
on a wooden pallet and shrink-wrapped.
When unpacking the product, suitable
lifting equipment and tools must be used
to remove the screw connections and
clamping devices between the burner
and the packaging. Suitable protective
clothing must be worn (gloves, safety
shoes).
Storage
In order to protect the burner from
environmental influences, it must be
placed in a dry, locked room when stored
temporarily. For the maximum storage
temperatures, please refer to the
technical data sheet.
Disposal
Local and currently
applicable legislation
must always be
observed.

Boiler lining
The burner lining must be installed at a
right angle to the burner tube. Possible
trimming work (bevelling, rounding) as
required for reverse boilers, for example,
should done at a diameter not below
70% of the combustion chamber
diameter. The space between the flame
tube of the burner and the boiler lining
should be lined with heat resistant
material, such as Cerafelt.
This space must not be lined with
brickwork

Burner installation
• Attach boiler front gasket to the burner
(see section entitled Burner front
gasket)
• Lift burner using hoisting eyes 19 (see
page 4 N6/7/8/9, see page 5 EKEVO
6/7/8/9) and fasten to the boiler.*
• Tighten the 4 fastening screws S2
(check the tightening torques).
* Alternatively a forklift truck may be
used for fixing it if the burner is fixed
to the transport pallet supplied with it.
Provision must be made for adequate
transportation safety. Suitable
transportation materials must be
used if necessary (lashing straps).
The leaktightness of the connection
between the burner and the boiler must
be tested during operation. It must be
ensured that exhaust cannot escape in
harmful quantities. Poorly sealed burner
boiler connections may result in
combustion problems.
Installation
Burner installation
The surface of the
entire circumference
must be sealed
Seal corners with
sealing tape
Burner flange seal (option 1)
The sealing tape in the accessories kit
must be affixed to the burner as shown
in the drawing below. The sealing tape
should be affixed without gaps in order
to prevent exhaust from escaping during
burner operation.
Please note:
Depending on the fibre diameter, the
mineral fibre sealing thermocord may
cause reversible mechanical irritation to
the eyes and skin. In the event of high
dust concentrations, risk of mechanical
irritation to upper respiratory tract.
When working with the sealing
thermocord, the operator should wear
loose-fitting, long-sleeved clothing. In
the event of high fibre dust
concentrations, the operator should
wear an FFP1 mask and well-sealed
protective goggles (also when carrying
out overhead work).
Burner flange seal (option 2)
• Check whether the gasket 1 is fitted
and in the correct position.
• Remove KB fixing clamps prior to
installation.
