Sorry, but there is no way to convert a zero clearance gas fireplace to wood burning. The standards for these two products are like night and day. Most important is that the chimney would not support the kinds of temperatures wood fires can generate. However, your house would likely burn down long before that caused a problem.

You simply can not do it.

Thanks for telling me that. Others are just saying to simply put an insert in and that's it. I'm glad I asked in this site.
