ECCO 448VP 4X48 B Vent Pipe 200450

The ECCO 200450 is a 4 inch diameter by 48 inch long section of double wall Type B vent pipe.

At 48 inches, this length covers a substantial vertical rise in a single piece, which reduces the number of joints in the run. Fewer joints means fewer opportunities for misalignment and fewer points where the assembly could be compromised, and it shortens installation time in the awkward positions where vent work is usually performed.

The double wall construction is what distinguishes Type B vent from single wall connector pipe. An inner liner carries the flue gases, an outer wall provides the exterior surface, and the insulating air space between them keeps the outer surface cool enough for the reduced clearance to combustibles specified in the listing, commonly one inch. Single wall connector pipe, by contrast, requires a six inch clearance, which is why B vent is used wherever a vent passes through framing, insulation, or an enclosed space.

That clearance must be maintained continuously. Insulation packed against a vent, framing that closes in against the pipe, or storage stacked around a chase all defeat the clearance the listing depends on.

Install male end down and female end up so condensate drains toward the appliance, and engage each twist lock joint fully.

Applications include residential and light commercial gas furnace, boiler, and water heater venting.
