1. OPERATING INSTRUCTIONS
1.1 Introduction
Dear Customer,
Thank you for choosing SUN G20, a twin-stage Ferroli burner featuring advanced design, cutting-edge
technology, high reliability and quality construction.
The SUN G20 is an oil burner, whose compact dimensions and original design make it ideal for use
with most of the boilers currently present on the market. The attention paid to its design and industrial
production has resulted in a product that is well-balanced with very low CO and NOx emissions and a
very silent flame.
1.2 Operating instructions
The operation of the burner, once correctly installed and adjusted, is
completely automatic and does not require any intervention by the user.
In the event of no fuel or operating anomalies, the burner stops and shu-
ts-down (the red light on the reset button turns on). It is recommended
to replete the supply of fuel before it runs out completely, to avoid the
inlet of air (irregular operation of the burner) or the loss of prime of the
pump (in which case the assistance of the service centre is required).
If the fuel tank is outside, in areas where the temperature falls below
-10 °C, the tank and fuel supply pipes must be adequately protected.
Use winter oil or add a specific anti-freeze.
Make sure that the room where the burner is installed is free of inflam-
mable objects or materials, corrosive gas or volatile substances, and is
not dusty. Dust, in fact, is sucked in by the fan and sticks to the blades of
the rotor and reduces air flow, or alternatively blocks the flame stability
disk, compromising efficiency.
Do not allow the burner to be tampered with by inexpert persons or children.
1.3 Maintenance
Make sure that maintenance is performed on the burner periodically, at least once a year. The mainte-
nance operations must be performed by qualified and specialist personnel according to the indications
contained in chapter 3.
1.4 Anomalies
If the burner does not ignite and the red light on the reset button is not on, check that there is electri-
cal power, that the heating system switch is on, that the fuses are intact and that there is an effective
request for heat from the boiler.
If the burner is still off (red light on the reset button on), wait 15 seconds and press the reset button to
reset operation. The burner will attempt to ignite. If it shuts down again, check that there is fuel in the
tank and that the manual valves located on the oil supply pipe are open. If these checks do not resolve
the problem, contact the service centre.
If noise is produced during the operation of the burner, contact the service centre.
