Stûv · Wood Inserts

Small spaces, generous fire.

A wood-burning insert “suited to small spaces while offering a generous view of the fire.”

I

A patented view

“The combustion chamber widens toward the front to reach the streamlined door frame” — a shape “unique to Stûv 6-in” (Pat. D898,173) that makes the fire the focus.

II

Made for masonry

“It is perfect for masonry hearths and for wood-fire enthusiasts” — the insert slides into the fireplace you already have. Three sizes, all Black.

III

Canada only

The maker’s own badge: “Available in Canada only.” UL · ULC · EPA · CSA B415.1-22 certified, 68% EPA efficiency across all three sizes.

Quick answers

The three things everyone asks.

Do I need a chimney?

Yes — wood needs one, and you already have it. The 6-in goes into an existing masonry fireplace with a stainless liner sized per Stûv’s installation instructions. We sweep it, line it and install it — WETT-certified.

Will it fit my fireplace?

Three sizes (66/50, 76/55, 76/60) cover most masonry openings. Send us a photo and three measurements — we’ll fit-check it against the maker’s install charts before you spend a dollar.

What’s the upkeep?

Ash out, glass wiped, and an annual sweep — which is our trade. Chase N’ Chimneys is a chimney company first: the crew that installs your 6-in is the crew that sweeps it every fall.

What it costs

Priced to your home — not from a chart.

Every wall is different — framing, venting, gas line — so your price is real, not a guess.
