I've gotten a lot of help from everyone here so I figured I'd throw this one on you too. I'm planning on using the PelletVent Pro Wall Thimble Air Intake Kit part #4PVP-WTI. Looking at the diagram in the catalog it looks to only have 4" in between the end plates. The other thimble kits are adjustable from 4"-8". Is this one adjustable also and they just didn't put it in the diagram or is it fixed like it shows in the picture? It seems to me that most exterior walls would need more than 4".
Thanks in advance for any help.
