COMBUSTION CHAMBER PRESSURE - MAXIMUM OUTPUT
(two nozzles in operation)
When the burner operates with only one nozzle, the pressurization conditions are improved and no problems arise.
Minimal fuel capacity with only one nozzle: 15 kg/h - 171 kW
Note for the extended combustion head version
Apply the extensions provided as accessories for the burner withdrawing.

FUEL OIL GRAVITY FEED SYSTEMS
Gravity system (fuel oil with viscosity max. 7°E at 50°C)
Pump priming: loose the tap of the
vacuometer plug 5) (fig. 1) and wait
for the fuel flow.
H: Difference in the pipes height.
L: Length of the suction pipe.
SUCTION SYSTEM (fuel oil with viscosity max. 7°E at 50°C)
Not advised, to be used only in case of previously existing system.
Never overcome the max. de-
pression of 0.5 bar (38 cm Hg).
With higher values the fuel ema-
nates gas.
The pipes shall be perfectly
sealed. When the tank is placed
below of the burner level, the re-
turn pipe should reach the same
level of the suction pipe.
In this case the foot valve is not
required.
RING SYSTEM (for heavy oil with viscosity up to 65°E / 50°C)
1- Tank (properly heated for heavy oil) 5- Forwarding pump
2- Filter (with resistance for oil >7°E/50°C) 6- Manometer
3- Burner 7- Burner pump
4- Couple of cocks (excluding the burner) 8- Pressure adjuster
Notice: All the pipes have to be properly seized, sealed and heated (elect. resistance or hot steam or water) to
let the fuel flow.
Warning: Before to put the burner in operation verify that no obstruction exists into the pipes, any obstruction may
damage the sealing of the pump.
