INSTALLATION
Feeding and suction line for light oil
SUCTION LINE LENGTHS FOR PIPE SYSTEMS
• Two-pipe siphon feed system
• Two-pipe lift system
WARNING: To calculate the length of the pipework all the straight parts, curves, up and down pipes must be taken into consideration.
The static suction height is the distance between the standing valve and the axis of the burner pump.
Negative pressure must not exceed 0,45 bar; if negative pressure is greater pump operation may become faulty, leading to an increase
in mechanical noise and perhaps even breakage.
All oil ring installations must comply with the local safety rules existing in the country of installation
The pumps that are used can be installed both into single-pipe and
double-pipe systems:
Single-pipe system: a single pipe drives the oil from the tank to the pump's
inlet that deliver the pressurized oil to the nozzle and part of the oil not used
goes back to the pump. With this single pipe the by-pass plug must be
removed and the return port must be sealed with steel plug and washer.
Double-pipe system: this is the default solution from the factory.
The return pipe send the excess oil from the pump to the tank. Depending
on the type of pump used to change from a 1-pipe system to a 2-pipe-
system, insert the by-pass plug (as for ccw-rotation referring to the pump
shaft).
Note for commissioning: during commissioning, the filter, pipelines and
pumps must be pre-filled with fuel oil and vented.
The direction of rotation of the motor should be checked. When
commissioning it must be ensured that pump never run dry.
NOZZLE SELECTION
Please refer to diagram to select Ecoflam recommended nozzle for the
output that is required given the output necessary in the installation.
Regular maintenance is highly recommended.
Nozzle has to be cleaned in petrol or paraffin and if filter or other parts are
defective or
damaged the nozzle must be replaced.

The burner is equipped with a self-priming pump which is capable of feeding
itself within the limits listed in the table at the side.
