Important Information:
- These are an Extremely Important Safety feature found on heaters. 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. Dirty threads, or over-tightening can break the shaft. This is not covered by warranty.
