The 5" round adjustable vent pipe is used with straight B vent pipe lengths in many exhaust applications. It can be used with natural gas or liquid propane, Category 1 appliances.
An adjustable pipe is used to add length to a straight length of Type B vent pipe. This 5" round, 12" adjustable pipe can add 3-1/2" to 10-1/2" to your straight pipe. A 2" overlap is required.
Some appliances that use Type B Gas Vent Systems include:
- Furnaces
- Water Heaters
- Boilers
- 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".
