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 delivery 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 maximum delivery required is set and controlled by both the stabilizer and
the gas valve.
