The seals on the door of your wood-burner or fireplace insert are essential if it is to function properly. They need to be replaced regularly.

What kind of seal?

The door seal: this creates an airtight seal between the door and the body of the device, and usually sits in a groove.

Unless your device is one of the exceptions specified below, you will need a round braided seal whose diameter is the same as the width of the groove. Place a small amount of adhesive at the bottom of the groove, not on the glass, and allow to dry for 2 to 3 hours before beginning to heat the device.

The glass panel seal: this is the one found around the edges of the interior side of the glass, between the door and the panel.

If there is a flat edging behind the glass panel of your stove or fireplace insert you will need a flat self-adhesive seal which you stick on to this flat edging or directly on to the glass. In most cases this is a 10 x 2mm seal, i.e. 10mm wide and 2mm thick, which is a standard size used by many stove manufacturers.
