What it is

The Ideal 003987 is a gas valve flange used on Ideal Elan RS series appliances. It forms the mounting and sealing joint between the gas valve and the appliance gas train, holding the valve squarely against its seat so gas is delivered at the correct pressure. The flange is supplied as an individual component and is identified by part number 003987.

Signs this part needs replacing

  • A smell of gas or a leak detected at the gas valve joint during a tightness test
  • Corrosion, pitting or staining across the flange face
  • Weeping or discolouration where the flange meets the gas valve body
  • Inlet or burner pressure that will not hold steady after the gas valve has been disturbed
  • A scored, distorted or flattened flange face found when the valve is removed for service

Before you order

  • Check the appliance GC number against the compatibility list before ordering, as several Elan RS variants share this flange.
  • Compare the alternative number 1170154 with any markings still legible on the old flange.
  • Inspect the mating face and any seal or gasket at the joint, and replace them if they show damage.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
