Introduction
As all burners covered by this standard come under the scope of EU directive 98/37/EC ; all requirements of
this standard and annex L shall apply.
This document is a type C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.

EN 676:2003/prA1:2005 (E)
L.1 Scope
according to clause 1 and addition:
Burners according to this standard are machines or components covered by the scope of EU directive
98/37/EC.
The risk philosophy adopted in this standard is based on the analysis of hazards on account of the application
of burners as machinery according to EU directive 98/37/EC.
This standard together with Annex L deals with all significant hazards, hazardous situations and events
relevant to burners, when they are used as intended and under the conditions foreseen by the manufacturer.
Any residual hazards are identified and communicated to the user where appropriate.
Depending on the installation situation additional requirements may apply to cover the risks arising from traffic,
wind, earthquake loading and external fire.
This standard specifies the requirements to be met by the manufacturer to ensure the safety of persons and
property during commissioning, start-up, operation, shut-down and maintenance, as well as in the event of
foreseeable faults or malfunctions. It specifies the safety requirements at stages in the life of the equipment,
and its design, ordering, construction and use.
This document is not applicable to burners which are manufactured before the date of publication of this
document by CEN.
L.4 Constructional and operational requirements
L 4.2.1 Design
according to clause 4.2.1 and addition:
The design of the burner shall be such that it can be handled safely. It must be designed and packaged so
that it can be stored safely and without damage.
Where the weight, size or shape of the burner or its components prevents them from being moved by hand,
they must be fitted with means to lift them easily.
The design and the construction of the burner shall be for automatic on/off or automatic operation without the
need of manual interaction.
L4.2.1 Accessibility for maintenance and use
according to clause 4.2.1 and addition
The moving parts of burners must be designed, built and laid out to avoid hazards or, where hazards persist,
fixed with guards or protective devices in such a way as to prevent all risk of contact which could lead to
accidents.
All necessary steps must be taken to prevent accidental blockage of moving parts involved in the work. In
cases where, despite the precautions taken, a blockage is likely to occur, manufacturers instructions and
possibly a sign on the burner should be provided by the manufacturer to enable the equipment to be safely
unblocked.

L.4.3.2 Electrical safety
Comprehensive instruction shall be given by the manufacturer about the requirements for the electrical
equipment and connection of the burner and which standard of pr EN 50156-1 or EN 60 335-1 is applicable.
NOTE EN 60335-1 stands for household application and similar use which includes appliances not intended for
normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be
used by laymen in shops, in light industry and on farms.
L.4.4 Functional and operational requirements
L.4.4.2 Operational requirements
L4.4.2.5 surface temperatures
Surface temperatures of burner parts reachable for the user shall not exceed 60 K above the ambient
temperature. If the temperature exceeds these limits caused by application conditions warnings or protection
measures shall be provided.
L4.4.10 Automatic operation
Prior to the automatic operation of the burner it shall be commissioned as declared in 6.4 by the manufacturer.
L.6.3 Other marking
The burner shall be marked with:
name and address of the manufacturer;
the CE-mark;
designation series or type;
serial number, if any;
year of construction.
L.6.4 Instructions for installation, adjustment, maintenance
according to clause 6.4 and addition:
The instruction shall include the information about the electrical safety of the equipment, handling, packaging
and transportation.
If there are different operation modes possible, they shall be clearly identified and described in the instructions.
