Bosch Greentherm 9000 series venting options

Global Pro Tankless Supply is now carrying the Bosch Greentherm 9000 series condensing tankless water heaters.  The new 9000 series heaters can be vented with PVC, CPVC, PP and also ABS-DWV.  The maximum flue temperature is limited to 145 degrees.  Global Protankless Supply is a Z-Flex distributor and we carry the Polypropylene venting and PP venting kits for vertical and horizontal installations.  There is a 1' minimum on the venting.  An external condensate drain T is not required as the heater has a down fired heat exchanger.  There is a condensate drain on the bottom of the heater and needs to be drained in accordance with the installation manual and per local codes.

Below are different options for venting the 9000 series tankless:

1.  Single exhaust vent going vertical or horizontal and intake air taken from the room installed.  This option is for warm climate areas where there is not a problem with cold air coming back down through the exhaust vent.

2.  Twin pipe exhaust and intake for vertical or horizontal installation.  It is recommended that the intake and exhaust be terminated out the same sidewall or roof area.

3.  Concentric vent termination using 3" PVC concentric vent system #196016.  This concentric vent system can be used for horizontal or vertical termination.  All other 3" PVC pictured is sold separately.

4.  Vertical venting system into a chimney using flexible PP.  Please note that the maximum length for the flexible PP is greatly reduced by 60%.  Example: 10 feet of flex PP is equivalent to 25 feet of rigid PP.

5.  Horizontal venting using the Z-Flex Z-Dens 2" Concentric Horizontal Kit (2ZDHK2).  The Z-Flex Z-Dens 2" Concentric Horizontal Kit 2ZDHK2 comes with a concentric termination horizontal, adaptor collinear to concentric, 2 locking clamps & 2 Adaptors CPVC / PVC Coupling to PP.  The Z-Dens 2"/4" Concentric Horizontal Vent Kit (2ZDHK2) is also available in 3"/4" (2ZDHK3) and 4"/6" (2ZDHK4).

6.  Vertical venting using the Z-Flex Z-Dens 2" Concentric Vertical Kit (2ZDVK2).  The Z-Flex Z-Dens 2" Concentric Vertical Kit 2ZDVK2 comes with a concentric termination vertical, adaptor collinear to concentric, 2 locking clamps & 2 Adaptors CPVC / PVC Coupling to PP.  The Z-Dens 2"/4" Concentric Vertical Vent Kit (2ZDVK2) is also available in 3"/4" (2ZDVK3) and 4"/6" (2ZDVK4).
