Features
- Dimensions: 3" Dia x 25' Long
- 2-ply .010" flexible liner
- Aluminum construction withstands high heat
- Protects masonry chimney from flue condensation
- Suitable for many Category I gas-fired appliances and fireplaces
The Dura-Vent DuraFlex Aluminum Chimney Liner for DirectVent Pro Co-Linear Chimney Systems is exactly what you need when converting your masonry chimney to Dura-Vent's co-linear direct vent system. Two layers of .005" aluminum create a single-wall liner that is both incredibly durable and lightweight. The high-quality construction withstands high heat while protecting the brickwork and mortar of your chimney from the condensation produced by gas fire features and appliances. The DuraFlex Aluminum Chimney Liner also works excellently with furnaces, boilers, water heaters, and more.
Please Note: DirectVent Pro, in combination with the gas appliance, has been tested and listed as a decorative gas appliance system or as a direct vent heater system by a major testing agency, such as UL, CSA, Warnock Hersey, or OMNI.

Customer Q&A with Product Specialists
Philip M.
from asked:
Can this be used in a wood-burning appliance?
Unfortunately, no. A wood-burning appliance will require a stainless steel liner system such as the DuraFlex 3 Inch Diameter x 25 Foot Long Kit of 304-Alloy Light Chimney Liner.
