Setting minimum / maximum gas levels
The maximum pressure setting must first be adjusted to ensure that burner will safely light
up, then the minimum pressure setting can be adjusted. Any adjustment of maximum
pressure setting influences minimum pressure setting, thus a minimum pressure setting
should always be re-adjusted after changing maximum value.

Adjusting the maximum pressure setting (see fig 7.3.)
Methode 1:
• Disconnect pressure feedback connection (if applicable).
• 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).
• Disconnect electrical connection of Moduplus®.
• Energize operator, set control in operation and wait until an outlet pressure is recorded
on pressure gauge.
• Push shaft gently downwards by means of a suitable pin through the hole on the top of
the Moduplus® to the bottom and hold it on.
• If maximum rate pressure needs adjustment then use an 8 mm wrench to turn
adjustment screw for maximum pressure setting clockwise to increase or
counterclockwise to decrease pressure, until the desired maximum outlet pressure is
obtained. Release shaft.
• Check minimum pressure setting and readjust if necessary.(according instructions
below) • Mount cap and reconnect pressure feedback connection (if applicable).
• If minimum and maximum pressures are set, wire the Moduplus® in circuit.
• Close pressure tap screw
Methode 2:
• Disconnect pressure feedback connection (if applicable).
• 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).
• Make sure that the appliance is in operation and the Moduplus® coil is energized with
maximum current.
• If maximum rate pressure needs adjustment then use an 8 mm wrench to turn
adjustment screw for maximum pressure setting clockwise to increase or counterclockwise
to decrease pressure, until the desired maximum outlet pressure is obtained. • Disconnect
electrical connection of Moduplus®
