Installation notes
- 1Ensure mortar completely seals the annular gap between porous plug and well block
- 2Connect argon line, test gas flow before tapping first heat
- 3After each campaign: inspect and measure plug erosion, replace if worn beyond safe limit
- 4Monitor gas pressure during heat, sudden pressure increase indicates plug clogging
