Important information
N6 and N7 G-V burners are designed for the
low-polluant combustion of natural gas. The
design and function of the burners meet
standard EN 676. They are suitable for use
with all heat generators complying with
standard within their respective performance
range. Any other type of application requires
the approval of ELCO.
Installation, start-up and maintenance must
only be carried out by authorised specialists
and all applicable guidelines and regulations
must be complied with.
Burner description
N6 and N7 G-V burners are modulating
pneumatic fully automatic monoblock
devices. Emissions values may differ,
depending on combustion chamber
dimensions, 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.
Packaging
The burner is supplied packaged in three
boxes on a pallet:
- Burner body with:
- integrated switch cabinet
- flange seal and securing screws
- operating instructions, circuit diagram
and spare parts list
- Combustion head
- Compact gas train with integrated or
external filter
The following standards should be observed
in order to ensure safe, environmentally
sound and energy-efficient operation:
EN 226
Connection of fuel oil and forced-draught gas
burners to a heat generator
EN 60335-1, -2-102
Specification for safety of household and
similar electrical appliances, particular
requirements for gas burning appliances
Gas lines
When installing the gas lines and trains, the
general directives and guidelines, as well as
the following national regulations, must be
observed:
CH: - G1 instruction text from SSIGE
- EKAS form no. 1942,
liquefied gas directive, part 2
- Cantonal authority guidelines
(e.g. directives for the pilot valve)
DE: - DVGW-TVR/TRGI
Installation location
The burner must not be used in rooms with
aggressive vapours (e.g. hair spray,
tetrachloroethylene, carbon tetrachloride),
high levels of dust or high air humidity (e.g.
laundry rooms).
If no connection to an air exhaust system is
provided for the air supply, there must be a
supply air inlet measuring:
DE: up to 50 kW: 150 cm2
per additional kW: : + 2.0 cm2
CH: QF [kW] x 6= ...cm2; but at least
200cm2.
Variations may arise as a result of local
regulations.
We accept no responsibility for damage
arising from:
- 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. Depending on
the type of installation, shorter maintenance
intervals may be necessary! It is advisable to
take out a maintenance contract to guarantee
regular servicing.
