Needing some guidance

[CMullis]

I recently bought a Country Hearth stove (2000 Model) and have some questions about clearances. I am wanting to build a non-combustible wall out of 29 gauge sheet metal and 1 inch spacers over my current wall, as I see that you can reduce clearances up to 67% using this method. However, I am confused by the fact that for double wall pipe you only need a 6 inch clearance, but in the manual it is saying I need 16.5 to 21 inches of clearance for the double wall pipe. Why is this?

This is because the stove clearance requirements are larger. Regrettably, the manual's documentation does not permit clearance reduction with wall shielding. There should be a sentence in the manual allowing this. If it did have this statement, then the minimal clearance with a proper NFPA 211 wall shield would be 12". Contact the manufacturer and see if you can get this exception in writing.
