4" Gas Chimney liner 316
4" (101mm) Gas Chimney Liner – Class 2 – 316 Grade Stainless Steel
Available to buy in increments of 2
This 4" flexible gas chimney liner is designed for use with gas and 28 sec oil appliances, offering safe and reliable flue lining for masonry and brick chimney stacks. Made from 316 grade stainless steel, the liner provides excellent corrosion resistance and durability for long-term performance.
Installation can be carried out from either the top or bottom of the chimney stack. Care must be taken to ensure clearance around the liner during installation to avoid snagging on internal brickwork. A nose cone and drawstring are required for installation (sold separately), and two-person handling is recommended for safe and smooth fitting.
