Bosch 5" B-Vent Vertical Vent Kit (H/P VVT)

The Bosch Vertical Vent Kit (H/P VVT) is a 5" Galvanized, Type B Vertical Vent Kit. This vertical vent kit includes a 5" x 12" pipe, (2) 5" flexible 90 degree elbows, a 5" fire stop support, a 5" roof flashing, a 5" storm collar, and a 5" rain cap. The HP VVT Vertical Vent Kit is manufactured by Selkirk and is used only for the Bosch Therm 520HN and 520PN naturally drafting heaters.  The H/P VVT vent kit will also work for the older retail models 1600H and 1600P.

The venting system must be designed and constructed so as to develop a positive flow adequate to remove flue gases to the outdoors.  Consult the National Fuel Gas Code if the vent will have elbows or share venting with another natural draft appliance.  The vent system must have at least a 12" rise off the top of the heater before any elbows or vent connectors.  

Selkirk 5 Inch Type B Venting Double-Walled Galvanized

GlobalTowne stocks 5" Selkirk Metalbest Type B Double-walled Galvanized vent pipe for the Bosch AquaStar 1600H and 1600P tankless water heaters.

The Selkirk Metalbestos 5" Type B vent pipe will connect up directly with the 1600H and 1600P tankless hot water heaters and will also connect up directly with the Bosch H/P VVT vertical vent kit.

The Bosch H/P VVT vertical vent kit contains all of the venting parts needed to vent the Bosch 1600H and 1600P heaters through the roof except for the straight pipe.

Our customers have found that ONLY the Selkirk Metalbest vent pipe will mate up with the H/P VVT vent kit piping, so this is the 5" Type B venting that we stock.
