COMBUSTION HEAD ADJUSTMENT
The pressurisation ring can be moved forward or backward by rotating the screw
“D” on the cover.
Note: Combustion head on model EM 12 cannot be adjusted.
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.
