Ideal Governor J78R 1in 13-19MB 113204

The Ideal 113204 is a gas governor used on Ideal Commercial Concord appliances. It is listed under part type GOVERNORS and carries the designation J78R 1in 13-19MB. The governor sits in the gas train and holds the pressure delivered downstream to the burner steady, so the appliance fires at the pressure its commissioning data calls for.

• Burner pressure reads outside the figure given in the appliance commissioning data and cannot be adjusted back into range.
• The flame becomes unstable, lifts off the burner or produces sooting at the heat exchanger.
• Pressure at the burner drifts as the appliance modulates or as other gas appliances on the same supply are used.
• Repeated ignition lockouts or flame-failure faults traced to the gas train rather than the ignition components.
• Debris or contamination found in the gas line upstream of the governor, with the governor no longer holding a steady outlet pressure.

• Match the GC number and the appliance model against the compatibility list before ordering, as several Concord variants share this gas train layout.
• Check the number marked on the governor already fitted; 1175730 may appear in place of 113204.
• Confirm whether the appliance uses a separate sealing washer or joint gasket at the governor connection, and order it if the existing one is disturbed.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
