Ideal 174789 Gas Valve Kit

The Ideal 174789 is a gas valve kit produced by Ideal for its domestic boiler range. The gas valve sits on the gas line into the appliance and controls the flow of gas to the burner, opening and closing on demand from the boiler's control board and modulating the gas rate to suit the heating or hot water load. It is catalogued under the Gas Valves & Solenoids part type and is supplied as a kit rather than as a bare valve body.

• The boiler fails to light, or lights and then drops out shortly afterwards
• Repeated lockouts or ignition fault codes logged at the control board
• The gas rate or flame picture cannot be set correctly during commissioning
• Audible clicking from the valve with no gas passing to the burner
• Intermittent heating or hot water with no other obvious cause found on the appliance

• Check the GC number and serial number on the appliance data badge against the compatibility information
• Confirm the valve currently fitted carries the same part number, as more than one gas valve has been used across Ideal's ranges
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
