The door gasket is one of the consumable parts of your Dwarf stove. Door gaskets typically last many years, but will eventually need replacement. If you notice that the burn rate of your stove is becoming more difficult to control, air might be leaking into the firebox through a worn out door gasket, bypassing your air controls.
To check your gasket, perform the “dollar bill test.” Place a dollar bill* halfway in the stove’s door jam, and close and latch the door to trap the bill. Then, pull the loose end of the bill out of the stove. If you feel any resistance when you pull, then the gasket is still good in that area. If the bill slides or falls out with no resistance, then your door gasket should be replaced.
To install a new gasket, unlatch the door, lift out the door pins, and remove the door from your stove. Thoroughly remove the old gasket and scrape off any old cement from the door surface. Then, dampen the area with water and apply a thin layer of cement to the gasket channel. Starting midway on one side (not a corner), press the new gasket firmly into the cement, being sure to keep the gasket material in a relaxed state, avoiding stretching it at the corners. Trim the gasket to length as needed, and use the included tape to secure the cut ends of the gasket.
Mount the door back on your stove, and close the door to ensure a good seal. Use the included door latch washers to adjust the fit of the door latch if necessary for the door to close properly with the new gasket. Allow to air dry for 1 hour with the door open. Fire the stove within 30 days and heat to 500 degrees F to cure the cement.
*Also works with other bank notes like Euros or pounds sterling. Doesn’t work as well with coins, gold bars, or cryptocurrency.

Question
Adam –
what size or diameter is this rope? is it universal? T.Y. can an image be posted with all the components as well as the instructions so we might feel comfortable installing ourselves, as opposed to hiring a servicer available locally?

Adam- The door gasket is 7/16” diameter Round and the glass gasket is ¼” diameter round. The video on this page outlines how to change the gasket on one of our Dwarf Stoves. The gasket replacement starts at around 3:30 once Nick goes over how to test the gasket and trouble shoot other aspects. As far as components, you need gasket rope, gasket cement, and something to remove the old gasket and clean the old cement from the door (typically a wire brush or flat head screwdriver). Hope that helps!

I have one of the early dwarf stoves where the knobs and handles don’t have the heat dissapation coils. It has the 4″ chimney. I bought 3/8″ rope for it before I realized it comes in different sizes. What size will I need?
