ADJUSTMENTS

The boiler exits from the factory already regulated.
Should it be necessary to adjust the minimum and maximum regulation of the gas valve for the hot water
supply, following operations should be carried out:
remove the power supply contacts from the coil (E) fed in low tension.
Power the boiler on in "SUMMER" mode and draw off hot water at max. flow-rate (10.8 l/min LAMBY 20
and 13.3 l/min LAMBY 24)
turn the adjustment screw (D) all the way down
loosen the locknut (B)
use a wrench to turn the coil screw (A) until maximum gas pressure (values are given on page 44) is
reached
tighten the locknut (B)
undo the adjustment screw (D) until minimum gas pressure (values are given on page 44) is reached
reconnect the coil (E)
This task sets the boiler so that it suits the needs of the user.
NOTE. To carry out this adjustment it is necessary to use a water-column pressure gauge, connecting it to
the pressure outlet (G).
