Setting the maximum heating circuit power

1. To set the maximum heating circuit power, turn the On/Off knob

o the “ON” position and set the time clock and any external

controls to the “ON” position. Turn the knob of the heating

hermostat clockwise to maximum.

2. Remove the inspection panel of the P.C.B. and fit a small cross-

head screwdriver in to the right hand potentiometer.

Turn clockwise to increase the pressure or anti-clockwise to

reduce the pressure. Adjust the setting to the required heating

pressure value (displayed on the pressure gauge), as indicated

Table B shown on Page 38 .

3. Turn off the boiler by placing the main switch to the "OFF"

position.

Setting the pressure for soft-light ignition.

1. Disconnect the detection electrode connection close to the

P.C.B.

(FIG. 4.1);

2. Start the boiler and during the ignition sequence adjust the left

hand potentiometer until the gas pressure reads the required

gas pressure (see the table on page 38 and 39);

3. Once the gas pressure is set turn off the boiler and re-connect

the detection electrode to the P.C.B.

NB.: It may be necessary to reset the flame failure reset a

number of times during this operation;

4. Remove the pipe from the test point and tighten the screw “C”

and test for tightness;

5. Carefully check the pressure test points for gas leaks (both inlet

and outlet).
