Ideal Gas Valve W45/60 174879

The Ideal 174879 is a gas valve supplied for the Ideal Commercial Imax range of boilers, covering the W45, W45P, W60 and W60P models. It sits on the gas train and regulates the flow of gas to the burner, opening and closing on demand from the appliance's control sequence. The valve is matched to the W45/60 chassis, so it is the correct fitment for these commercial units rather than a generic replacement.

• The boiler fails to light, or lights and then drops out shortly after ignition.
• The burner will not hold a stable flame, with repeated lockouts on the control panel.
• Gas pressure readings at the valve outlet fall outside the values given in the appliance manual.
• The valve body shows signs of leakage, corrosion or a sticking solenoid.
• The appliance runs erratically or shuts down during a demand for heat.

• Confirm the appliance model and GC number against the compatibility list, as the W45, W45P, W60 and W60P variants are listed separately.
• Check the valve currently fitted against the part number 174879 and the alternative number 1780522.
• Inspect the gas train seals and gaskets at the same time, as these are disturbed when the valve is removed.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
