The 6" round vent pipe is used for many B vent exhaust applications. It can be used with natural gas or liquid propane, Category 1 appliances.
This vent pipe is a 6 inch round / 24 inch long rigid pipe. Additional lengths can be added for longer lengths. It can not
be cut for shorter lengths.
Some appliances that use Type B Gas Vent Systems include:
- Water Heaters
- Room Heaters
- Decorative Gas Appliances
- Unit Heaters
To calculate installed length, subtract 1 1/2" from each connection of vent. A 1" clearance to combustible materials must be maintained. To calculate Outer Dimension (OD) add 5/8".
Actual pipe length is 24".
