Ideal Gas Valve HE C24 173925

This gas valve, part number 173925, is manufactured by Ideal for use in their Excel HE range of boilers. It is compatible with the C24, C28 and C32 models, and is responsible for controlling the flow of gas to the burner. The valve opens and closes in response to signals from the boiler's control system, ensuring safe and efficient combustion. This part is supplied in used condition and comes with a 6-month warranty.

• Boiler fails to fire or ignite: When the gas valve fails, the boiler may attempt to start but not produce a flame. This often results in a lockout or error code on the boiler's display.
• Intermittent or no gas supply: The valve may stick or fail to open fully, leading to reduced gas flow. This can cause poor combustion, sooting, or the boiler cutting out during operation.
• Flame failure or lockout errors: The boiler's flame detection system may not sense a flame, causing repeated lockouts. This is a common symptom of a faulty gas valve.
• Unusual noises: A failing gas valve may produce clicking, buzzing, or humming noises when the boiler tries to ignite. These noises can indicate internal wear or solenoid failure.
• Visible damage or corrosion: Inspect the valve for signs of corrosion, leaks, or physical damage. Any of these indicate the valve should be replaced.

• Check the GC number on your boiler matches one of the listed models: 47-348-35, 47-348-36, or 47-348-37. The GC number is usually found on the boiler's data plate.
• Confirm the part number 173925 or the alternative number 1179717. This ensures you receive the correct valve for your appliance.
• Consider whether a new gasket or seal kit is required for the gas valve connection. Reusing old seals can lead to gas leaks.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
