What it is

The ASD pilot assembly with gauze is a Johnson & Starley pilot burner component for the Eljan, Janus and Superjan families of water heaters and circulators. It provides the standing pilot flame that lights the main burner, and the assembly incorporates a gauze element at the pilot head. It is supplied under part number 1000-0704265.

Signs this part needs replacing

  • The pilot will not light, or lights and then goes out
  • The pilot flame is weak, unstable or noticeably yellow rather than a steady blue
  • Soot, dust or debris is visible on the gauze at the pilot head
  • The appliance repeatedly locks out or fails to establish a flame
  • The pilot assembly shows corrosion, cracking or mechanical damage

Before you order

  • Read the model and GC number from the appliance data badge and check it against the fit list above
  • Confirm the existing pilot assembly matches the layout and connections of this part
  • Note that fitment varies between Eljan, Janus and Superjan variants, so check the exact model rather than the range name alone
