Gas Monoblocs (Non Modulating Burners); Pressure Controller - FULTON J Series Installation, Operation And Maintenance Manual

2
If the pressure control is fitted with a differential
scale: (see OEM literature in Section 5)
1. Set the main scale pressure to the maximum
pressure required (system pressure).
Do not exceed the boiler operating pressure.
2. Set the differential scale to it's minimum
pressure. If the pressure control has a fixed
differential, i.e. no adjustable differential
scale, set the main scale to the maximum
pressure required.
When multiple boilers are fitted with a
sequence control:
1. Set the main scale and differential scale as
above.
2. Set the setback pressure control to the
required set back pressure.
Note: In order to utilise the maximum flash steam capability of the boiler it is essential that the boiler is operated
at the maximum working pressure (10.34 bar) and then pressure reduced down to the required system pressure.

GAS MONOBLOCS (NON MODULATING BURNERS)

Setting the gas pressure switch. - Models 6 - 30
1. Remove the adjustable gas pressure switch cover.
2. Set the pressure switch by rotating the setting wheel to the desired pressure.
Normally set to 2.5 mbar below the normal supply pressure with the boiler running.
Setting the pressure regulator. - Models 6 - 30
1. Remove the regulator cover.
2. Using a screwdriver, set the regulator to the desired pressure:
Clockwise to increase pressure. Anticlockwise to decrease pressure.
Gas pressure can be tested at the test point on top of the gas output flange.
Setting the main gas flow (V2) - Models 6 - 30. - factory set, would not normally be altered.
1. Loosen the security screw on the setting plate.
2. Turn the setting plate: Clockwise to reduce gas flow. Anticlockwise to increase gas flow.
Rapid stroke adjustment Model 6 - 30 - factory set, to slowest possible opening,
would not normally be altered.
1. Unscrew the adjustment cap from the hydraulic brake.
2. Invert the cap and use as a tool: Clockwise = slowest opening time.
Anticlockwise = fastest opening time.
