FULLY MODULATING
The correct setting for fully modulating operation is made by adjusting the parameters via the
Siemens LMV burner controller.
All adjustments need to be carried out by a suitably trained service engineer.
All parameter adjustments are password protected.
Setting the gas pressure switch.
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.
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)
- 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
- 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.
