I think you did the right thing; better safe than sorry. If the wood is cedar, even small amounts can be fairly toxic to reptiles (pine not as much). Cedar has a very strong odor so you should be able to tell.
I use pro product RHP in my neodeshas, visions, crescent moon creations, and habitat system cages and have never had to construct things to lower the heat panels closer to the floor; particularly in Vision cages since most of the models are fairly low.

>>I recently built a wooden structure to support a lowered RHP in my Vision 632 to bring the RHP closer to the surface for my desired temps. After building and mounting the thing, it occurred to me that cedar and pine are supposed to be toxic to reptiles when used as a substrate. Im not even sure what type of wood it is. Im not sure if having a few pieces of wood in the cage, assuming its one of these woods mentioned, provides enough toxicity to be harmful. To be safe, I removed it until I receive further information.
