Description of burner

The burners VECTRON
G 03.240/300 DUO PLUS are 2-stage
progressive/modulating burners in a
monoblock configuration. Within their
corresponding power range, they are
suitable for use with all heat generators
designed to conform to EN303.
For any other use, the agreement of
ELCO must be asked for.
The special design of the burner head,
with internal fume recirculation, permits
highly efficient combustion - while
ensuring minimum emissions of
nitrogen oxide.

Important notes

The design and function of this burner
both conform to EN 676 standards.
All installation, initial-startup and
maintenance work must be carried out
by authorised service engineers, who
should observe all relevant guidelines,
directives and specifications.
The installation of the gas conduits and
valve assemblies should likewise be
carried out in conformity with the
applicable directives and regulations
(e.g. DVGW-TRGI 1986/96 ; TRF 1988 ;
DIN 4756).
All seals and sealing material used
must be DVGW tested and approved.
Check seals and connection points for
possible leaks with a suitable
non-corrosive foam product.
Bleed the gas conduit before using for
the first time. DO NOT bleed via the
furnace. Servicing work on switches,
limiting devices and control units - along
with other safety devices - MUST be
carried out by the supplier of each
individual item, or by its authorised
service engineers. Original parts may
only be replaced by an authorised
service engineer.
