Door Rope and seals is a consumable item on a stove and will need replacing after a period of time.
When do you need to change the door rope seal on a stove?
1 - The stove may be roaring away more than usual due to air leak.
2 - Less control over the fire
3 - You can visibly see the seal has come off or has compressed significantly
The Stove should be air tight to ensure complete control, if the seal has gone you do a simple test.
When the Stove is cold
Close the door with a piece of paper behind the door. If the paper is easy to pull it out then the seal is not working very well and it is time to replace the door rope seals. If the rope has split or frayed or is coming off the door then you should also replace it.
You can find the correct door rope seals under the spares for certain models if you can’t find the door rope seal for your stove please.
Checking the grate on your stove is important as replacing a grate or parts of a grate such as grate bars is better to do before the grate fails. Check for signs of cracks or bends.
Baffle Plates also known as Throat plates are classed as a consumable item and will need replacing after a period time once burnt out. Baffle Plate are positioned at the top position of the fire box in a stove prevent flames shooting straight up the chimney. A Baffle plate is essential for the efficient running of a stove. However due to the position of the baffle plate being the hottest part of the stove it is inevitable the plate will burn out.
Baffle Plates varies in material from Steel, Cast Iron and Vermiculite. Your Stove manual should tell you how to remove the baffle plate for cleaning.
How often you will have to replace your Baffle Plate will depend on how you use your stove such as; type of fuel you burn, the size of the fuel load and how you burn your fuel.
If you are not sure on what fuels to use you should refer to the stove manual with the list of recommend fuels for that stove.
One common reason for a Baffle Plate burning out is over firing the stove allowing continuous high temperature over long periods of time will shorten the lifespan of the throat plate. You can prevent this buy using the Stove thermometer.
Checking the Firebricks inside of your stove is also important to do on a regular basis. Firebricks & metal liners do an important job of protecting the Stove body from the direct high temperatures produced during the combustion process. Firebricks prevent the stove body from warping and cast iron stoves from cracking.
Small cracks in the firebricks are not necessarily an indication that the bricks need replacing. However if the crack is significant where part of the brick will drop off then the brick needs replacing. If the brick as crumbled away and you can see exposed metal you also need to change the brick.
