In a similar way, the ‘S’ switch can be used as an auxiliary signal switch for any actuator stroke position.
Turn the ‘S’ screw clockwise for a signal at a higher stroke or flow. Turning counterclockwise reduces stroke
or flow level to activate the switch.
To adjust the ignition flow, turn the ‘S’ screw. Turn the screw clockwise to reduce and counterclockwise to
increase the flow required for proper ignition.
Switch R
To adjust the reduced flow rate or low fire position, turn the ‘R’ (‘Reduced’) screw. Turn the screw clockwise
to reduce and counterclockwise to increase the flow for stage one.
Switch MR
The switch MR for Manual Restart stops gas from being automatically released again after a power cut.
For Manual Restart operate the red button on the terminal box cover for at least 3 seconds to drive the gas
valve to the open position, see Figure 3.
Should the button not be held long enough the gas valve will automatically return to the closed position.
