Due to the intense heat that is generated by the burner ignitor boxes can prove to be quite difficult to remove. Over time the nut that holds the ignitor box in can become corroded and hermetically sealed to your bottom casting. Below are a some recommended steps to assist in successfully removing your GGIB.
- First, soak the nuts on both the underside and inside of your bottom casting with a penetrating oil like WD-40 or Liquid Wrench. Let this soak for several hours and you may want to give these areas a couple of doses of the penetrating oil.
- If you have not been to remove the ignitor box after soaking with penetrating oil you can try tapping or chiseling it out.
- Another suggestion to remove a stubborn ignitor box is to drill it out once the majority of the part has been removed. Below is a photo of what should be left before attempting to drill this out.
