Quick answer: To replace your Mr. Heater Burner tile, you’ll need to buy a replacement burner tile kit for your Mr. Heater model. Then, you can disassemble your heater, loosen the bracket holding the ceramic tile, and replace the tile and the gasket.

Steps to Replace Your Mr. Heater Ceramic Burner Tile

1. Look up the Model Number of your Mr Heater

First of all, you need to buy the necessary replacement parts. But replacement parts are often labeled using the official model number.

So, let’s first look up the model number of your Mr. Heater model:

Mr. Heater ModelModel Nr.
Mr. Heater Little BuddyMH4B
Mr. Heater BuddyMH9BX
Mr. Heater Hunting BuddyMH12B
Mr. Heater Big BuddyMH18B

If your model is not on the list, look it up directly on the back side of your Mr. Heater unit.

My Mr. Heater Buddy has the Model number MH8BXDF. I think the model number differs from the table above because I have a European model.

Or, alternatively, look up the model number on a sales page of your Mr. Heater model. On Amazon, you’ll usually find the model number in the description of the heater.

2. Get a Replacement Burner Tile and Gasket

For a complete burner tile replacement, you’ll need 

  • a fitting replacement burner tile and
  • a burner gasket (the old one is likely burnt and can’t be reused)

The burner burner gasket is a piece of felt that insulates gas leaks.

Usually, the tile and the gasket are sold together in a kit. If you can’t find a kit, you can also buy them separately.

If you live in the US, buy from the official Mr. Heater website.

Often, on the official website, replacement parts are out of stock. Or, if you live overseas, possibly you can’t order at directly

3. Disassemble your Mr. Heater unit

Once you have the replacement parts for your Mr. Heater, you’ll need to disassemble it to access the ceramic burner tile.

The disassembly varies from model to model:

4. Replace old burner tile

To replace the old burner tile, gently remove it from its bracket. Likely, you’ll need to loosen the bracket using one or two screws responsible for tightening and loosing which sit at the bottom of the contraption.

Remove the old burner tile. Scrape out the old gasket. Likely it’s burnt and falls apart.

Put the new felt gasket in place.

After that, position the new burner tile in the bracket ensuring it sits flat and snug.

Once the new burner tile is in place, tighten the bracket screw securely to hold the burner tile in place. Ensure it’s well-secured but not overly tightened to prevent any damage to the new tile, especially when it heats up.

5. Reassemble your Mr. Heater

Now, it’s time to reassemble the heater. Follow the disassembly steps in reverse to put your heater back together.

Start by securing the front panel, then reattach the handle using the screws you had removed.

Ensure all screws are tightened securely but not overly so to avoid damaging the heater.

6. Test the Heater

After you’ve successfully reassembled your Mr. Heater, it’s crucial to test it to ensure the burner tile replacement was successful and that the heater operates correctly.

Turn on your Mr. Heater and observe the flame. It should ignite smoothly and produce a clean, blue flame.

If it doesn’t, double-check your work to ensure everything has been reassembled correctly. You can cross-check with this guide: How to fix a Mr. Heater Buddy not lighting

Safety Precautions

Disconnect the propane heater before you start the disassembly for the tile replacement. An accidental punctuation of the gas hose or the gas bottle can lead to dangerous gas leaks.

Always ensure to work in a well-ventilated area when replacing the burner tile of your Mr. Heater.

It’s also advisable to have a fire extinguisher nearby for safety. Make sure the heater has cooled down completely before you start the replacement process, and ensure there is no gas leakage during the assembly or disassembly.


In conclusion, replacing the ceramic burner tile in your Mr. Heater is a straightforward task when you follow the correct steps.

With the right tools and a little patience, you can extend the life of your heater and continue enjoying warm and comfortable spaces during the cold months.
