5.3.5 GAS PRESSURE/HEAT INPUT GRAPHICS – MODELS CF
1. To check the minimum power loosen screw “2” (fig.B) and insert
the pressure gauge fitting pipe in the pressure intake.
2. Disconnect the compensation pipe of the air chamber (fig.B).
3. Have the boiler work on minimum power and disconnect a cable
from the modulator (fig.D). The supply pressure must correspond with
the one foreseen for the type of gas for which the boiler has been
prearranged (refer to table below). If it does not correspond, act on
adjusting screw “4” (fig.D) while holding the hexagon nut steady
“3”(fig.C).
4. After checking tighten screw “2” and check sealing.
5. Reconnect the cable of the modulator.
6. Reconnect the compensation pipe
Regulation carried out on parameter 2 20
1. To check the slow ignition power, loosen screw “2” (fig.B) and
insert the pipe of the pressure gauge in the pressure intake.
2. Disconnect the air chamber compensation pipe (fig.B)(sealed
chamber).
3. Open the tap of the hot water, the burner turns on, disconnect the
detection electrode in order to have the slow ignition pressure for 8
seconds before safety block.
4. Change parameter 2 20 (see paragraph 6.2 and 6.3).
