F. Adjusting the Minimum Pressure Setting
1. Disconnect pressure feedback connection (if
applicable).
2. Connect a suitable pressure gauge to pipe line or to
outlet pressure tap of gas control concerned, to
measure burner pressure (measuring point must be as
near to burner as possible).
3. Disconnect electrical connection of the Moduplus®.
4. Energize operator, set control in operation and wait until
an outlet pressure is recorded on pressure gauge.
5. If minimum rate pressure needs adjustment, use an 8
mm wrench to turn adjustment screw for minimum
pressure setting (clockwise to increase or counter-
clockwise to decrease pressure), until the desired
minimum outlet pressure is obtained.
6. Check if main burner lights easily and reliably at
minimum pressure.
7. Reconnect pressure feedback connection (if applicable).
8. Close pressure tap screw.
