I have a general question regarding exhaust pipe clearances for an install of a Breckwell Big E. The owner's manual states 3" inch pipe clearance from combustible materials, which coincides with Simpson's Pelletvent pipe literature.  But Simpson also offers Pelletvent Pro, which is UL listed for 1" clearance to combustibles.
Could I go with the Pelletvent Pro, and be closer than the Breckwell manual requires?
Thanks-
Tim
