General information

The EK4...L-ZA series of ELCO light oil
burners, featuring monobloc design and
fully automatic two-stage operation, are
suitable for the combustion of extra­light fuel oil. Design and performance of
the burners comply with currently appli

­cable guidelines and regulations.
Burner installation and start-up must be
performed by a qualified expert who is
responsible for the proper execution of
these tasks.
The burner complies with the standards

EN 267
DIN 4787

Observe the following standards to
ensure safe, environmentally friendly
and energy-saving operation of the
burner.

DIN 4755

Oil-burning installations in heating
systems.

DIN 4789

Connection of atomizing oil burners and
blower gas burners to heat generators.

EN 60335-1

Safety of electrical appliances for
domestic use

Site of installation

The burner must not be operated in
rooms with aggressive fumes (e.g.
hairspray, tetrachloroethylene, carbon
