On the conventional setups, use 30-pound mono and 40-pound braid with the spinning gear. Top bait is the largest live menhaden in the well. For lure color, Burge is a big fan of chartreuse. Worthy Catch: Little fishing pressure and fish happy to bite mean Burge has the opportunity to hook plenty of tarpon.
First the furnace: The 1/4 slope is for the intake, not the exaust pipe. There is no mention of specific slope requirements for the exaust pipe, other then sloping upwards (there is a drain for the exaust blower comparment in the furnace).
If you have a vent pipe (most likely you do), you should have ordered an appropriate sized pipe boot with a metal/rubber flexible adjustable bottom, designed for corrugated sheet and standing seam metal roofs. I hope you aligned your panels so that the stink pipe lands between the ribs.
