Fresh Air Intake Kits for Wood Stoves

Fresh air intake kits and insulated flex pipe for Drolet, Englander and other SBI-built wood stoves and inserts — with no sales tax in any state and free shipping on orders over $250.

Which kit fits your stove?

Every kit here is 5", so the diameter is never the decision — the mounting is. Find your model below. A stove on a pedestal takes a different kit from the same stove on legs, and inserts take a different kit again.

A dash in the Base column means SBI lists a single kit for that model rather than separate pedestal and leg versions. The Escape 1800 appears twice because it is sold both ways — check which base you have before ordering. Every kit needs 4' insulated 5" flex pipe ($33) to reach the wall, and the airtight register with damper ($285) is the sealed termination for the outside end. Linked models are stoves we stock; Osburn, Enerzone and Century appliances are built by SBI on the same chassis, and we sell the parts for them but not those stoves.

When you actually need one

A wood stove burns a surprising volume of air every hour and it has to come from somewhere. In an older, draughty house it leaks in through the building itself. In a tight modern build — or any house with a powerful range hood, bathroom fans, a dryer, or a basement install — the stove ends up competing for that air, and the result is a lazy fire, smoke rolling out of the door on reload, and cold draughts pulled in through every gap in the house. An outside air kit gives the firebox its own supply so it stops taking the room's. An intake kit feeds the firebox with combustion air from outside instead of out of the room, so the stove stops competing with range hoods, bath fans and the dryer for air in a tight house.

Mobile home installs are the clear-cut case: an outside air connection is required, not optional. Basement stoves are next most common, because the stack effect works against them.

What you'll need for installation

The kit attaches at the stove. To reach the outside wall you need insulated 5" flex pipe — insulated matters, because uninsulated duct carrying cold outside air will sweat in a warm room — and a sealed termination outside. The airtight register with damper closes the intake off when the stove isn't running. Keep the run as short and straight as the layout allows, and terminate it away from anything that could draw exhaust back in. The rest of the install is covered in our clearances guide and the fresh air intake guide. Floor protection is a separate requirement — see hearth pads.

Fresh air intake FAQs

Do I actually need a fresh air kit?

It is required for mobile home installs. It is strongly recommended for tight, well-sealed houses, for basement installs, and for any home where running a range hood or bath fan makes the fire misbehave. An older leaky house with the stove on the main floor often runs fine without one.

How do I know which kit fits my stove?

Match your model in the table above. If your stove is sold both on a pedestal and on legs, the two take different kits — the Escape 1800 is the model this catches out most often.

Are these all 5 inch?

Yes. Every kit here is 5" and they all use the same 5" insulated flex pipe to reach the wall, so diameter is never the decision — only the mounting.

Can I run the intake through the floor instead of the wall?

Often yes, if the floor gives onto a vented crawlspace or the outside. The requirement is that the air comes from outdoors, not from a sealed basement, garage or attic. Your stove's manual gives the permitted routes.

Will an outside air kit make the stove burn hotter?

It makes it burn consistently. The gain is a fire that lights readily, holds its draft and doesn't spill smoke when you open the door — not a higher heat output figure.

Do these fit Osburn, Enerzone or Century stoves?

Yes. Those are SBI brands built on the same chassis as the Drolet models listed, so these are the correct factory intake kits for them. We sell the part, not those appliances.

Do you charge sales tax on fresh air intake kits?

No. StoveSource charges no sales tax in any state, and orders over $250 ship free to the lower 48.
