Learn how to install and maintain the Hawu roll chimney for your tent stove. Get practical steps, common mistakes, and care tips to extend its life.

Quick answer

Install the Hawu roll chimney by aligning the embossed surface outward for maximum heat radiation, and maintain it by cleaning soot after each trip and inspecting for creases or punctures before storage.

Why the embossed surface matters

The Hawu roll chimney’s embossed surface isn’t just for looks — it increases the heat emissive area, which directly improves the fuel-to-effect ratio of your stove. That means more warmth from less wood. During installation, always face the embossed side outward so it can radiate heat into the tent rather than back into the pipe.

Common installation mistakes

A frequent error is forcing the chimney into a tight stove collar without first checking the fit. The Hawu roll chimney is designed to be lightweight and packable, but it can crease if bent too sharply. Another mistake is using it without a spark arrestor in dry conditions — though the chimney itself is durable, hot embers can escape if the top isn’t secured properly.

Installation and maintenance steps

Check compatibility before assembly: Ensure the Hawu roll chimney fits snugly into your stove collar. The pipe is designed for the Hawu tent system and wood stove, but always verify the diameter and collar type. A loose fit can leak smoke and reduce draft. A mismatch in diameter is the top cause of poor draft.
Position the embossed side outward: Unroll the chimney and identify the embossed surface. Face that side away from the pipe interior — toward the tent. This directs radiant heat into the living space instead of back into the stovepipe. Wrong orientation cuts heat output by up to half.
Secure the chimney at both ends: Attach the base to the stove collar and the top to the tent’s chimney port (if used). Use the provided fasteners or a snug friction fit. For hot tent setups, a spark arrestor at the top is recommended to prevent embers from escaping. An unsecured top can shift in wind and create a fire risk.
Clean soot after each trip: Once the chimney is cool, wipe the interior with a dry cloth or brush to remove creosote and soot buildup. Avoid water, which can cause rust on steel components. Regular cleaning maintains draft and reduces fire hazard. Soot buildup narrows the pipe and increases the chance of chimney fires.
Inspect for damage before storage: Check the entire length for creases, punctures, or flattened sections. The lightweight design is durable but can be damaged if packed while wet or stored under heavy gear. Store it loosely rolled in a dry place. A small puncture can grow into a tear during use.

Product facts

Hawu roll chimney: The Hawu roll chimney has an embossed surface that increases heat emissive area, improving the fuel-to-effect ratio of the stove it’s used with. Orienting the embossed side outward during installation maximizes heat radiation into your tent, making your stove more efficient.
