What it is

The Johnson & Starley 1000-0301900 is an air vent cap intended for the manual air vent on Johnson & Starley Reno boilers. It caps the manual air vent point on the appliance, sealing the vent once air has been released from the system. It is a small service component supplied by Johnson & Starley for use on the Reno range.

Signs this part needs replacing

  • The cap is missing from the manual air vent, leaving the vent open
  • Water weeps or drips from the manual air vent with the cap fitted
  • The cap is cracked, split or deformed
  • The cap will not seat or tighten correctly on the vent body
  • Air cannot be held in the system after venting because the vent does not seal

Before you order

  • Confirm the appliance model against the fit list above
  • Check whether the manual air vent itself is damaged as well as the cap
  • Verify the part number 1000-0301900 matches the item being replaced
