If you are installing a wood stove into an existing fireplace opening, the answer is almost always yes. A liner is not an upgrade. It is the part that keeps the stove safe and working.
Why a stove needs its own liner
A wood stove burns hotter and smokes less than an open fireplace, and it connects to a much smaller flue. If that stove vents into a wide, unlined masonry chimney, smoke cools quickly, drops creosote on the walls and drafts poorly. A properly sized liner keeps the exhaust hot and moving.
What a liner does
- Keeps exhaust gases and heat inside the flue instead of the masonry
- Improves draft so the stove burns cleanly
- Reduces creosote buildup
- Protects old mortar joints from acidic condensation
Choosing a liner
| Type | Best for |
|---|---|
| Stainless steel flexible | Wood stoves and inserts in standard chimneys |
| Cast in place | Damaged or irregular flues needing structural help |
| Clay tile | Open fireplaces only, not stoves |
| Insulated stainless | Exterior chimneys and cold climates |
What the installation involves
- Inspect the existing flue with a camera.
- Choose the liner size from the stove manufacturer specifications.
- Lower the liner from the top, connect it to the stove adapter and seal the top plate.
- Add a cap and test the draft.
The EPA Burn Wise program also lists certified stoves that burn cleaner, which pairs well with a new liner. Our liner installation team sizes everything to your exact stove.
Common questions
How long does a stainless liner last? Many carry lifetime warranties when installed properly.
Do I need a permit? Often yes in Connecticut. Your installer can confirm with your town.
