The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instructions. Refer to the furnace installation instructions for intake/vent pipe sizing information. NOTE: The Concentric Vent reduces the allowable intake/vent piping length by 5 feet from that listed in the basic furnace installation instructions. Do not use the Concentric Vent kit for anything other than a Category IV furnace. sku CVENT-2 weight (in lbs) 10.000000 brand/manufacturer Online Supply additional information Length of Termination Kit: 33 1/2" safety information PROPOSITION 65 WARNINGThis product and many products on our site may contain a chemical know to the state of California to cause cancer or birth defects or other reproductive harm.
