Why Choose the WM106XR / M106XR Round Dump Grate?

A damaged or worn fire grate can restrict airflow, cause uneven burning, and reduce stove efficiency. Replacing it with this 12-1/2 inch cast iron Warm Morning dump grate restores proper combustion, improves heat output, and makes ash removal easier. Built for long-term performance, this grate is an essential replacement part for keeping your Warm Morning stove operating safely and efficiently.

Installation Instructions:

Always allow the stove to cool completely before servicing. Ensure all embers are fully extinguished and remove any remaining ash from the firebox.

Open the stove door and remove any remaining fuel. Access the existing grate by opening the ash door or removing internal firebox components as required by your stove model.

If the stove uses a grate slide mechanism, disconnect the grate from the slide linkage. Carefully lift out the old dump grate. Inspect the firebox supports and clean away ash or debris before installing the new grate.

Position the new round dump grate into the firebox reminder ring or support ledge, ensuring it sits flat and centered. Reattach the grate slide linkage if applicable and confirm smooth rotation or rocking movement.

Before lighting the stove, operate the grate slide handle to verify proper movement and clearance. Once confirmed, reload fuel and resume normal operation.

Installation tip: Always confirm that the grate rotates or dumps freely without binding. For full operation, this grate must be paired with a compatible WM672R Grate Slide.
