Fuel-oil connection
Electrical connection
Fuel oil connection
Enclosed diagrams provide required
pipe diameters.
There are two following possibilities:
- Direct suction:
According to length L and suction or
load height H and chance mishaps ;
These lengths include the presence of
a quarter-turn hand-operated valve, a
check valve and four elbows.
Maximum negative pressure 0.4bar.
- Transfer loop:
According to the type of facility,
booster pump characteristics will have
to meet several criteria, notably:
- hourly flow,
- fluid flow speed,
- maximum boosting pressure.
Preference should be given to this
type of installation, in order to obtain
long spray pump life.
In both cases, it is compulsory to fit a
120µm filter and quarter-turn
hand-operated valve on the suction or
booster (not supplied).
Important:
Suction:
• Totally fill suction pipe between spray
pump and tank down-pipe with fuel oil.
Transfer loop:
• Fill, boost, drain and set pressure in
circuit at 2bar max. It is advisable to
install a pressure switch to limit burner
operation to boost pressure.
• Check for possible leaks.

Combustion head settings
Head setting values (space between
nozzle and turbulator - dimension B,
space between nozzle and ignition
electrodes - dimension C) can be
checked with enclosed drawing. The two
dimensions are set in the factory.
Dimension B was set thanks to adjust
ring 5. While reassembling the turbulator
for a nozzle replacement, it is not
necessary to re-adjust dimension B, as
far as the turbulator is re-assembled on
the stop on ring 5.

Secondary air
This is the flow of air admitted between
the turbulator diameter and then
blast tube.
The position of the turbulator
(dimension Y) can be read from the
scale graduated from 0 to 35mm.
Maximum secondary air is indicated by
the 35 mark and minimum secondary air
by 0.
It can be adjusted according to:
- ignition quality (shock, vibration,
chatter, delay),
- combustion efficiency.

Safety units characteristics
FUEL-OIL control and safety units
- SH 113 (one stage),
- SH 213 (two stages),
are appliances of which the programme
is managed by a microcontroller. They
also integrate the defect analysis
through coded luminous signals.
When the unit is defective, button R
lights on. The defect code appears every
ten seconds until the resetting of the
unit.
Further investigations are possible by
reading the microcontroller non volatile
memory.
The unit ceases to function when the
voltage falls below the required
minimum value. It restarts automatically
when the normal voltage is restored.
A thermostatically controlled switching
off is compulsory every twenty four
hours.
The removal and setting up of the
unit take place with the unit de-
energised. The unit must be
neither opened nor repaired.
