Nuway Gas Pressure Switch GW 10/50

The Dungs GW 10/50 is a gas pressure switch used to monitor gas pressure within the gas train of a combustion appliance. It is listed here under Nuway SKU C50048X and is fitted to Nuway MDFL gas trains and NGN gas burners. The switch provides a pressure signal to the appliance control sequence, allowing the burner to prove gas pressure at the relevant point in the start-up and running cycle.

• The burner locks out or fails to complete its start-up sequence when gas pressure proving is required
• Intermittent lockouts that clear on reset and recur without an obvious cause elsewhere in the gas train
• The appliance will not fire despite gas being present at the train
• The switch shows physical damage, contamination or a disturbed electrical connection
• Pressure proving behaves inconsistently between start-up attempts

• Confirm the appliance model against the fits list above before ordering
• Check the type reference on the existing switch matches Dungs GW 10/50
• Verify the SKU C50048X against the current part fitted to the gas train
• Gas train and burner work must be carried out by a competent person
