Important notes
VG 1.40/55/85/105 burners are
designed for the low-pollutant
combustion of natural gas and Liquefied
Petroleum Gas. The design and function
of the burners comply with standard
EN676. They are suitable for use with all
heat generators complying with EN 303
or for use with hot air generators
complying with DIN 4794, and DIN
30697 within their respective
performance range. Use for any other
application requires the approval of
ELCO. Assembly and commissioning
must be carried out only by authorised
specialists and all applicable guidelines
and directives must be observed.
Burner description
The VG 1.40/55/85/105 are single-
stage, fully automatic, monoblock type
burners. The special design of the
burner head provides low-polluting
combustion with high efficiency. In line
with testing as defined by EN676, the
values comply with emissions class 3 -
the most stringent standard - and also
fulfils the requirements of national
environmental legislation:
AT: KFA 1995, FAV 1997
CH: LRV 2005
DE: 1.BImSChV
NL: EN676, emission class 3
Emissions values may differ, depending
on combustion chamber dimensions,
combustion chamber load and the firing
system (three-pass boilers, U-fired
boilers). For specifying warranty values,
the conditions for the measuring
equipment, tolerances and humidity
must be observed.
Scope of delivery
The burner packaging also contains:
1 gas connection flange
1 compact gas train with gas filter
1 Burner flange with insulation
1 bag containing installation fittings
1 bag containing Technical
Documentation
The following standards should be
observed in order to ensure safe,
environmentally sound and energy-
efficient operation:
EN 676
Forced-draught gas burners
EN 226
Connection of vaporising oil and forced-
draught gas burners to the heat
generator
EN 60335-2
Safety of electrical equipment for
domestic use
Gas lines
When routing gas lines and trains,
observe the general installation
regulations and directives as well as
national guidelines:
CH: - SVGW gas directives G1
- EKAS Form.1942 Liquefied
Petroleum Gas- directive, part 2
- Regulations on cantonal
instances (e.g. fire department
regulations)
DE: - DVGW-TVR/TRGI
Place of installation
The burner must not be used in rooms
exposed to aggressive vapours (e.g.
hairspray, tetrachloroethylene or carbon
tetrachloride), large amounts of dust, or
high levels of air humidity (e.g. in laundry
rooms). An air inlet must be present
with:
DE: up to 50 kW: 150 cm
2
per additional kW: + 2.0 cm
2
CH: QF [kW] x 6= ...cm
2
; but at least
200 cm
2
.
Variations may arise as a result of local
regulations.
We can accept no warranty liability
whatsoever for loss, damage or injury
caused by any of the following:
- Inappropriate use.
- Incorrect assembly or repair by the
customer or any third party, including
the fitting of non-original parts.
Provision of the system and the
operating instructions
The firing system manufacturer 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, and
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
strongly recommended to take out a
service contract to guarantee regular
servicing.
