Keep your Savotta stove safe and efficient. Learn how to clean and replace the 85 mm spark arrestor, a simple spare part that reduces fire risk in the field.

Quick answer

Clean the 85 mm spark arrestor after every few uses to prevent clogging, and replace it if the mesh is damaged or heavily corroded to maintain safe stove operation.

Why the spark arrestor matters

The spark arrestor is a simple mesh cap that fits over the stovepipe. Its job is to catch embers and sparks before they can escape and start a wildfire. A clogged or damaged arrestor reduces airflow, makes your stove burn inefficiently, and defeats its safety purpose.

Savotta's 85 mm spark arrestor is a direct replacement part for their stove system. It's built to the same quality standards as the original, so you can swap it in minutes without modifying anything.

When to clean vs. when to replace

Clean the arrestor when you see soot buildup or reduced draft. A quick brush or tap is usually enough. Replace it if the mesh has holes, tears, or heavy rust that can't be cleaned away. A damaged arrestor won't stop sparks reliably.

Carrying a spare spark arrestor in your kit is smart field practice. It weighs almost nothing and takes up no space, but it can save you from a dangerous situation if the original fails.

How to clean and replace the 85 mm spark arrestor

1. Let the stove cool completely: Never attempt to clean or replace the spark arrestor while the stove is hot. Wait until the stove and pipe are cool to the touch to avoid burns. Checkpoint: Even a stove that feels warm can cause injury—wait an extra 10 minutes.
2. Remove the arrestor from the stovepipe: The 85 mm spark arrestor sits on top of the stovepipe. Gently lift it off. If it's stuck due to soot or resin, tap the side lightly with a tool or gloved hand to break the seal. Common mistake: Forcing the arrestor off can bend the mesh. Tap, don't pry.
3. Clean the mesh: Use a stiff brush (like a wire brush) to remove soot and debris from the mesh. Tap the arrestor against a solid surface to dislodge stubborn particles. For heavy buildup, rinse with water and dry thoroughly before reinstalling. Checkpoint: Do not use oil or solvents—they can leave residues that burn off and produce smoke.
4. Inspect for damage: Hold the arrestor up to light and look for holes, tears, or thin spots in the mesh. Check the rim for cracks or deformation. If you see any damage, replace the arrestor. Common mistake: Assuming a small hole is harmless. Even one hole can let sparks escape.
5. Install the cleaned or new arrestor: Place the arrestor back on the stovepipe, ensuring it sits evenly and snugly. If you're using a new Savotta 85 mm spark arrestor, it will fit without any modification. Checkpoint: A loose arrestor can fall off during use. Give it a gentle wiggle to confirm it's secure.
6. Test for proper fit and airflow: Light a small fire and observe the draft. The stove should draw normally, and no sparks should escape around the arrestor. If you notice smoke leaking or poor draft, re-check the fit. Common mistake: Skipping the test run. Always verify before relying on the stove in the field.
