How To Change Your Outdoor Furnace Door Rope Gasket

How To Change Your Outdoor Furnace Door Rope Gasket

Supplies needed:

All outdoor wood furnace door seals should be replaced every 2-3 years so we want you to know how it's done.

If you do not change your door rope gasket, you risk the following problems:

- Reduced efficiency

- Waste your precious wood fuel

- Increase your workload

- Possible furnace overheating

- Possible loss of furnace water (and outdoor boiler water treatment!) that must be replaced

- In rare cases, damage to overheated steel, particularly the door frame

Changing the outdoor wood stove door seal gasket should be very easy. When it is time to change your outdoor boiler door seal, follow these simple steps.

1. Let your fire burn down completely. Leaving the door open too long can ruin your outdoor wood boiler and may void your warranty, not to mention that the heat would create an unsafe and uncomfortable working environment.

2. Strip out the old door rope. Using pliers, screwdrivers or other tools as necessary, remove the old door rope and clean the channel where the rope seats. Use acetone or other products to clean the channel. Use caution with any cleaning product.

If the product is flammable, like acetone, the fire should be completely removed from the firebox. Safety first. Be sure the channel is dry before continuing to the next step.

3. Glue in the new rope gasket. Outdoor Wood Burning Boilers use a highly specialized rope gasket available only from - You can find it at our online store HERE. Place a thick bead of silicone inside the channel of the door.

Push the new rope gasket into place all the way around the door. When you get to the end, use a sharp knife to trim the rope to length. The ends of the rope should touch to keep the gasket tight.

4. Close the door. You may need to adjust it to fit properly. Keeping the door closed will hold the gasket in place while the silicone or glue set up.

You can start burning again right away. Just be sure the door gasket stays in place while you build your fire back up.

If you have any other questions about door gaskets or anything else to do with your outdoor wood burner consult your Owner's Manual or feel free to contact us for technical support at this link HERE:

Remember to keep your fire and coals 6 to 8 inches back from the shelf of the door chute. This will extend the life of your door seal. Also remember that the fire rope gasket is permeable and some smoke escaping is normal.

Free Water Testing

One of the most important steps in prolonging the life of your outdoor boiler is to ensure that the water in your boiler is not corroding the steel. Water starts to eat holes in steel immediately upon contact (through rust corrosion) UNLESS the water is properly treated with a special corrosion inhibitor chemical that has been formulated to protect the exact grade of steel in your furnace - Liquid Armor Water Treatment.

But because water quality is very different in different parts of the country, the exact amount of water treatment you will need in your furnace will depend upon many factors - this is why you need to submit your water sample for FREE water testing. We test your outdoor boiler water for free!
