Concentric Vent Insulation. Follow guidelines set by local regulatory authorities or local build

Follow guidelines set by local regulatory authorities or local building codes with regard to framing, boot or flashing requirements for ceiling, floor or roof penetrations made by the Concentric Vent kit and associated vent piping. The problem is that leaves get in and make it all the way to the burner. But I could imagine that concentric vents may cause more condensation in the flue gas, since the combustion air flows in around the center flue pipe. This is an alternative to the standard two pipe intake/vent shown in the basic furnace The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. Partially assemble the concentric vent termination kit per Figures 1 and 2. WARNING Do not tamper with the System 636 vent components. No need to uncoil flex, insulate a majority of the pipe, or protect the insulation when installing. Required for installations that pass through an attic to prevent insulation from accumulating near the vent. It is the only factory-insulated product with zero/zero clearance for high heat wood-burning appliances. Cement Y concentric vent fitting to larger diam-eter kit pipe. 4quozyrtbf
