Hi All,


I am converting an old building into a Maple Sugar house. It will have a wood-fired evaporator (with blower) vented with 10" stainless steel single wall stove pipe. I expect some pretty darn high flue gas temps. The roof of the building is framed with trusses, 24" o.c. The nature of this setup makes it so that the stovepipe passes about 6" from the 2x4 truss members in a few spots, which is too close for my comfort. Any suggestions on a solution?


- Attach ceramic fiber insulation to the trusses where the pipe passes closely by?
- Fab up small heat shields to attached to the trusses at the questionable points?
- Combination of the above too?
- I already have all the single-wall pipe, but should I buy a few short pieces of double-wall pipe for the trouble spots? Can I go back and forth from single to double-wall? I'd say this is my least preferred choice, but I'd obviously do it if it means not burning the place down.

Thank you for any thoughts.
