Z-Flex Z-Vent Stainless Steel Vent Pipe

The Bosch Therm 940ES and Bosch Therm 830ES tankless water heaters require either 3" or 4" single wall stainless steel venting.

The Bosch Therm 940ES is a 199,000 BTU heater and the Bosch Therm 830ES is a 175,000 BTU heater. Read the manual carefully as these two heaters have been approved for longer runs using 4" Z-Flex stainless steel venting.

At Pro Water Heater Supply we carry the full line up of Z-Flex Z-Vent 3" and 4" stainless steel vent pipe. This special single wall venting is rated AL29-4C and is approved for Category I (vertical only), II, III & IV applications and is designed for use with boilers, high efficiency gas and oil heaters and water heaters where cool flue gases are vented under pressure.

Z-Vent contains a built-in, fail-safe gasket and locking band connection. No sealant is required.

Z-Vent is available in up to 24" diameter and is also used to vent boilers.
