1 1st/2nd stage delivery adjustment lock screw
2 Stabilizer adjustment
3 Protective cover for initial fast-start adjustment device
4 2nd stage delivery adjustment
5 1st stage delivery adjustment
To adjust the 1st/2nd stage delivery loosen screw 1. Turning 4 and 5 anti-
clockwise increases the delivery. Turning clockwise reduces the delivery. Once
you have carried out the necessary adjustments re-tighten screw 1. To adjust
the initial fast-start mechanism remove the cover 3 and, using the rear of the
cover as a tool, rotate the pin.
GAS VALVE ADJUSTMENT
The maximum delivery and the start up delivery must be set.
MAXIMUM DELIVERY ADJUSTMENT
- Assemble a gauge to measure the gas pressure at the burner head.
- Open the gas valve to the maximum.
- While the burner is working, act on the stabilizer until the required delive-
ry is reached (read the meter): read the pressure value on the gauge.
- Act on the valve adjustment by turning the valve towards off until the
pressure on the gauge just hints at decreasing. At this point the maxi-
mum delivery required is set and controlled by both the stabilizer and the
gas valve.
CHECKING THE QUANTITY OF GAS AT IGNITION
To check the quantity of gas at ignition, apply the following formula:
Ts x Qs 100
where Ts = Safety time in seconds
Qs = Energy freed in safety time expressed in kW
The Qs value is obtained from:
where Q1 = delivery expressed in liters freed in no. 10 startups in safety time.
Ts1 = total safety time of 10 startups
Qn = Rated output
To obtain Q1, proceed as follows:
- Detach the lead from the control electrode (ionization electrode).
- Read the gas meter before the test.
- Perform 10 burner startups; these correspond to 10 safety lock-outs. Read the gas meter again; by subtracting the first
reading, the Q1 value is obtained.
