Ideal 171441 Honeywell VR4601A1036 240v Gas Valve

The Ideal 171441 is a gas valve kit intended for use in Ideal domestic boilers from the Classic, British Gas, Classic Slimline and Optia ranges. The gas valve regulates the flow of gas into the burner, opening and modulating supply in response to the boiler's demand signal, so it sits at the centre of safe combustion control. This kit is supplied as an assembly rather than a single component, allowing the valve to be replaced as a unit during servicing or repair.

• The boiler fails to light, or lights and then drops out shortly afterwards
• Repeated lockouts on the gas valve or ignition fault codes
• The burner flame is weak, unstable or noticeably different in appearance
• Heating and hot water become intermittent, with the boiler responding poorly to demand
• A smell of gas around the appliance, which requires the boiler to be isolated and an engineer called immediately

• Confirm the boiler model and GC number against the compatibility list, as the same appliance name can cover several build variants
• Check the existing valve and any associated seals or gaskets before fitting, and replace worn items as part of the job
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
