4" Innoflue flex vent - sold by 2ft long increments. Indicate 1/2 of the total (continuous) length required in the Qty field (i.e. Qty 20 is 20 x 2ft = 40ft length). Max continuous length is 80ft.
Why 2ft? While most of the Innoflue 4" flex pipe is corrugated, it has smooth sections about every 2ft (24"), which have the same diameter as the 4" SW (Single Wall) pipe. This eliminates the need for transition adapters (couplers) and allows for direct connection of Flex pipe to a female (hub) oulet of a SW pipe or fitting.
For a chimney installation, consider purchasing together with IFCKC03 kit.
