Restore draft performance and improve flue safety with this 4‑inch flexible stainless steel chimney liner kit, engineered to reline existing masonry or factory‑built channels while providing a durable, smoke‑tight exhaust pathway. The 35‑foot continuous coil delivers adequate length for standard residential runs plus the necessary slack to navigate terminal collars, insulation wraps, and vertical offsets without creating seam junctions.
Physical Dimensions and Appliance Match
Crafted from corrugated stainless steel, the liner expands and compresses along its longitudinal axis, allowing it to snake through preexisting chase pipes and angled chimney sections that rigid conduits cannot traverse. A steady 4‑inch internal diameter aligns with common venting requirements for most certified wood inserts, pellet stoves, and gas fireplace systems. This proportion pairs the exhaust opening closely with the appliance manifold, eliminating excess void space that encourages moisture accumulation and draft stagnation.
Complete Hardware Integration
- Liner Coil: 35 feet of flexible, single‑wall stainless tube
- Mounting Hardware: Securing clamps, base brackets, and tensioning straps for stable anchoring
- Termination Fittings: Flashing plates, drip collars, and roof pipe caps for exterior sealing
Provided as a coordinated package instead of an isolated roll, this system eliminates component searching and ensures dimensional consistency between the liner and every attachment point. Installing it over damaged clay tiles or degraded aluminum baffles restores a smooth interior surface, accelerates hot‑gas draw, and extends the operational lifespan of both the vent structure and the heat‑generating unit.
