Found on the Outlet side of a gas pool or spa heater heater. Also called a Thermal Cutout or Thermal Safety Cutout Switch.

Part Number 71031. 

These suit all Hurlcon Astralpool HX, MX, Viron, HiNRG, JX Gas Heaters. Also suits Jacuzzi J-HN250C & J-HN400C heaters.

Failed hi limits can cause the F2 Errors found on Hurlcon and Astral Gas Heaters. Commonly fail due to condensation and leaks. Should be replaced every few years as part of preventative maintenance.

Both Inlet & Outlet hi limits should be replaced at the same time.

There are two types, threaded (Viron, HiNRG, later HX, JX, MX) which is screwed into the brass plug, and non-threaded style that is held in either by a bracket (older MX), or screws (older JX, HX).

Notes & Installation:

  • Astralpool / Hurlcon gas heaters have a brass plug this screws into. Ensure it is not leaking or corroded. Replace if necessary.

Important Information:

  • These are an Extremely Important Safety feature found on heaters, and are required by law. They must be replaced when necessary. 
  • When installing, make sure both male & female thread are clean. We recommend lightly lubricating the thread, and *gently* screwing them in, as the thread shaft is thin brass.
