DuraVent 4" Diameter By 12" Length Type B Round Gas Vent Pipe -4GV12

Description: Type B double-wall air-insulated pipe is an inexpensive solution for an expensive chimney when venting gas appliances. Gas appliances produce a huge amount of water vapor during combustion that can condense inside chimneys and damaging them and leaking through walls. This insulated pipe maintains high flue temperatures and reduces condensation inside the vent. The higher flue temperatures also maintains a higher draft, which is important when carbon monoxide is involved. This Type B vent or chimney takes up a lot less space than most other chimneys, especially a brick and mortar chimney and can be closer to flammable materials, as close as 1 inch, than most other chimneys or single wall flue pipes can be to combustibles. This double-wall pipe with aluminum inner wall for corrosion resistance and galvanized steel outer pipe for strength is a Type B gas component and consists of the DuraLock system for a tight seal. This pipe can be used as a vent or chimney for venting listed natural gas or liquid propane Category I, draft hood appliances, or appliances that have been specifically tested and listed to use Type B Gas Vent. Typically, Furnaces, Water Heaters, Boilers, Room Heaters, Decorative Gas Appliances, and Unit Heaters can vent to Type B vents. These appliances can also be vented to the vent or chimney using Type B vent pipe as an insulated flue pipe, To calculate installed length, subtract 1 1/2” from each pipe to compensate for overlap with the DuraLock connection of one pipe to the next. A 1” clearance (air space) to combustible materials must be maintained around the pipe. To calculate OD add 5/8”. UL Listed. Formerly brand was Simpson Dura-Vent. Not suitable for venting oil, coal, pellet or woodburning appliances, or fumes containing grease that could ignite.After 43 years, we closed down our chimney sweep business and a year later are selling all our brand new inventory for 50% (or more) off wholesale list prices. We are much cheaper than most others on eBay, as we are not trying to make a profit, but need to clear out our inventory for good at a loss. Once one of our listings is sold out, it is gone for good. We were a service business, so we don't mind answering any technical or aesthetic questions about these products and how they work. Will do combined shipping.
