Cleaning your catalytic combustor is easy with the right tools! You will need 7/16” and ½” wrenches and a 5/32” Allen wrench. Gloves and eye protection are recommended.

Access the combustor by removing the 4 Allen bolts in the top or rear flue cover plate using the Allen wrench. Always be sure the stove is cool before starting!

Once the plate is off, use a 7/16” wrench or nut driver to remove the bolt holding up the combustor shield.

Remove the shield carefully as the edges may be sharp. Wear gloves if you have them.

If they were not removed during installation, you may need to remove the shipping bolts with the ½ inch wrench. They would be located at the two ends of the combustor box.

Lift the front edge of the combustor box and rotate it 90 degrees to bring it out of the stove.

After about 6 weeks of burning, or after each cord of wood, your combustor may have some fly-ash accumulation.

Use a household vacuum, a shop vac, or a soft bristled clean paintbrush to gently clean both the top and bottom of the combustor. Hold the combustor up to the light to be sure the cells are clean.

While the combustor box is out of the stove, vacuum or brush the area below where the combustor sits. Clean off the cast iron plate and the metal screen.

Put the combustor box back in and rotate it 90 Degrees to sit back on it’s gasketed opening. Be sure the side of the combustor box with the bolt hole for the shield is facing toward you.

You do not need to re-install the shipping bolts. Re-install shield and tighten the 7/16” bolt.

Replace the flue cover plate and tighten the 4 Allen bolts with the 5/32” Allen wrench.

Cleaning your combustor every 6 weeks, or after every cord of wood, will keep your stove running at peak efficiency and extend the life of your catalytic combustor.
