Checks before commissioning
Electrical connection
The electrical installation and
connection work must only be carried
out by an authorised electrical specialist.
All applicable rules and regulations must
be observed.
This burner contains electronic
components; it is advisable to connect a
type A FI multipole switch upstream of
the system to detect error currents with
a direct current component.
• Check to ensure that the power supply
voltage is as specified (230 V, 50 Hz)
• Burner fuse: 10 A.
The burner and heat generator are
connected by a 7-pin connector
1
.
Oil connection
The oil hoses supplied are already
connected to the oil burner pump. The
supply hose is individually marked to
reduce the risk of swapping the hoses.
The oil is connected by a single pipe
system with bleed filter. The filter must
be located in such a way that the correct
hose routing cannot be impaired. The
hoses must not kink.
Cu pipe DN 4 (4x6) should be used as a
fuel-oil tube.
CH: Polyamide fuel-oil tube DN4,
DIN 16773, item no. 501183.
For threshold values for suction line
lengths and suction heights, see the
guideline for planning and dimensioning
plants with suction installations. This
guideline is an integral part of the ELCO
planning criteria. The Procal guideline
applies for CH.
The suction conduit is passed up to 5 cm
above the tank floor in cubic tanks, and
up to 10 cm above the tank floor in
cylindrical tanks.
Electrical connection for water
protection valve (CH)
• The water protection valve (installation
site) is located on connector
C
.
Oil burner pump
The oil burner pump used is a self-
priming gear pump, which must be
connected as two-line pump via a bleed
filter.
There is an intake filter and an oil
pressure regulator integrated in the
pump.
Cleaning the pump filter
The filter is located underneath screw

Checks before commissioning
Check the following points on the
system:
- Water pressure in heating circuit
- Circulation pumps in operation
- Additional air device in flue operable (if
present)
- Power supply (230 V) to the boiler
control panel is ensured
- Oil level in tank
- Oil hose connections (feed/return,
tightness)
- Open fuel-oil valves
- Burner combustion head settings
- Ignition electrode settings
- Thermostat settings
Before start-up, draw up oil with a hand
pump. Switch on the burner for start-up.
Open the bleed screw at the oil filter to
allow the oil line to bleed fully. Negative
pressure should not drop below 0.4 bar.
Close the bleed screw once the filter is
completely full of oil and the oil comes
out free of bubbles.
