5" double wall DSP like oil flue pipe (not low temp)
Who makes a smoke pipe similar to the Selkirk DS(P) series double wall connector pipe in a 5" ID? This is for my ordered Thermo Pride OH6, which requires 5" pipe, rather than the 6" my current furnace uses. TP says is should be rated for at least 1000 degree F maximum temperature. It will be tough to get the 18" clearance local code requires for single wall pipe, even though TP only requires a 7" flue clearance, due to a low basement ceiling. Everything I've seen so far is for low temperature venting. Anybody aware of such a product? I don't have room for an expander right at the furnace, and would prefer to avoid venting out the side of the furnace if I can. A double wall 90 deg elbow in 5" would be perfect! I could then expand to my current 6" double wall after that.
Is anybody aware of such a 5" pipe?
