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 re-
quired is set and controlled by both the stabilizer and
the gas valve.
