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.
