HOW TO…
Replace My Stove Baffle Throat Plate.

Replacing a stove baffle plate (sometimes called a throat plate) is an important maintenance task that helps your wood stove burn efficiently and safely. The baffle plate reflects heat back into the firebox, improves combustion, and protects the stove’s flue outlet from direct flame contact.
Important: Please Read Before Continuing
Before You Begin
- Make sure the stove is completely cool.
- Use safety gloves to avoid injury where possible.
- Use a dust mask if you're sensitive to ash or fine debris.
- Have your replacement baffle plate ready.
Important Tips
Be aware of the order to re-install the fire brick back into the stove!!!
What You’ll Need:
- Replacement baffle plate (make sure it’s the correct part for your stove model)
- Screwdriver or socket wrench (if fasteners are involved)
- Gloves (to protect from soot, ash, and sharp edges)
- Optional: Vacuum or brush for cleaning the stove interior
Step-by-Step Instructions:
-
1. Let the Stove Cool Completely
- Never attempt to replace the baffle plate when the stove is hot. Wait until it’s completely cool to the touch.
-
2. Open the Stove Door
- Fully open the main stove door for maximum access to the firebox area.
-
3. Remove Internal Parts (if needed)
- Take out any firebricks, grates, or other internal components that may block access to the baffle plate.
- Take note of how they’re arranged so you can put them back in the same order.
-
4. Locate and Remove the Old Baffle Plate
Most baffle plates sit on internal support ledges or brackets near the top of the firebox. Some may be screwed in, while others simply rest in place.
If yours is fastened:
- Use a screwdriver or socket wrench to remove the screws or bolts.
- Support the plate with one hand while removing fasteners—it may drop unexpectedly.
If yours is loose-fitting:
- Tilt or slide the baffle plate out carefully, usually by angling it downward and removing it from the stove at an angle.
-
5. Clean the Area
- While the baffle plate is out, it’s a great opportunity to clean soot and ash buildup from the top of the firebox or around the flue outlet.
-
6. Install the New Baffle Plate
Position the new plate the same way the original was installed:
- Slide or tilt it into place above the firebox.
- Rest it on the existing support brackets or ledges.
- If fasteners are used, tighten them gently but firmly—don’t overtighten and risk cracking the plate.
-
7. Reinstall Internal Components
- Put any firebricks, grates, or ash pans back in place in the same order you removed them.
-
8. Check the Fit
- Make sure the new baffle plate is secure, doesn’t rattle or shift, and doesn’t obstruct the flue or airflow.
Pro Tips:
- Always use the correct part: Baffle plates are model-specific—check your stove’s manual or call Stovebay.com if unsure.
- A damaged or warped baffle plate can reduce stove efficiency and cause excessive flue temperature or creosote buildup.
- Replace baffle plates as soon as they show signs of sagging, cracks, or corrosion.
