Product Information
About
Premium 304 Stainless Steel Built for Pellet Stove Venting: Engineered from heavy-duty 304 stainless steel at a rugged .006 inch wall thickness, this FireSafe flexible chimney liner is purpose-built to withstand the acidic moisture and creosote that pellet stove exhaust produces. The 7-ply seams and corrugated construction create a gas-tight, watertight barrier that resists chimney fires and carbon monoxide leakage for decades.
Complete Kit with Step-Down Reducer for 3 Inch Stove Collars: This all-in-one kit includes the FireSafe 4 inch flexible 304 stainless steel chimney liner, a 4 inch to 3 inch increaser/reducer adapter to bridge a 3 inch pellet stove exhaust collar to the larger 4 inch liner, a 13 inch by 13 inch heavy-duty top plate with EZ Connect collar, and a square stainless steel rain cap. No additional adapters or sealants needed.
Why Upgrade to a 4 Inch Liner on a 3 Inch Stove: A larger 4 inch flexible chimney liner improves draft performance on longer chimney runs and reduces creosote accumulation over time, even when your pellet stove uses a 3 inch exhaust collar. The included step-down reducer adapter handles the transition cleanly, giving you better long-term performance than a 3 inch liner alone.
Maximum Flexibility for Tight Offsets and Easy Install: The 4 inch FireSafe liner stays highly pliable through tight bends, offset flues, and irregular masonry chimneys while the reducer adapter seats securely on your pellet stove's 3 inch exhaust collar. The EZ Connect system simplifies installation with user-friendly collars, so DIY homeowners and chimney sweeps can complete the install without specialty tools.
Proudly Made in the USA - Lifetime Transferable Warranty: Manufactured in the USA from mill-certified stainless steel and backed by a comprehensive lifetime transferable warranty, this FireSafe pellet stove liner kit is engineered to outlast your home. An investment in quality craftsmanship designed to protect your family, your chimney, and your peace of mind for years to come.
