Operation:

  • The PTR valve is designed to relieve excess pressure caused by water expanding during the heating cycle.
  • It is NORMAL for the PTR valve to release drips of hot water during the heating cycle if no Expansion Control Valve is fitted.
  • If the water heater thermostat fails to operate correctly, the PTR valve will discharge hot water when the temperature reaches 99ºC.
  • Fitting an Expansion Control Valve to a hot water system will prolong the life of the PTR valve and the water heater.
  • It is recommended to flush the PTR valve every six months to clear deposits from around the valve seat.
  • The date of manufacture can be found on the Indicator Disc. See warranty statement for further information.
  • Never expose valves to a torch-flame or heat. Heat will destroy the seals and sealing parts.

Installation:

  • NEFA valves should always be installed by a licensed plumber in accordance with National Plumbing and Drainage Code AS/NZ3500.4.
  • The installation must also comply with any Local Authority requirements and the water heater manufacturer’s requirements.
  • Don’t install valve if temperature probe is damaged or bent.
  • Ensure flushing handle is accessible.
  • Check the inlet water pressure does not exceed the maximum stated in the table below.
  • Ensure that sealing materials, e.g. thread tape or thread sealing paste, do not intrude into flow passages as this could cause obstruction to flow and failure of the valve.
  • Install PLV and/or ECV, if required, as stated in the table below.
  • Install drain line in accordance with AS/NZ3500.4
