Cracks in the bricks/vermiculite plates may happen due to bumps from the wood. There is no need to replace the bricks even though they are cracked. They do still insulate the fire chamber.
The purpose of the bricks is to insulate the fire chamber to increase the combustion temperature. However, if they start crumbling, the insulation disappears. This may damage the cast iron and they do in this case have to be replaced.
Cleaning & Maintenance

In addition to Morsø's 10-year product warranty, Morsø supplies spare parts for our wood-burning stoves for up to 10 years after a stove type has been discontinued.
The warranty period is calculated from the date of sale.
The warranty does not cover:
- Wear parts, i.e. parts that wear out during normal use (e.g. smoke deflector plates, grates, refractory stones/plates as well as glass and sealing materials). The provisions of the Sales Act on liability for defects apply to these parts.
- In the event of lack of maintenance and breakage of the product's surface treatment, corrosion can occur. The warranty does not cover such occurrences. The provisions of the Sales Act on liability for defects also apply here.
- Damage caused by incorrect installation and use, including in relation to applicable public regulations and Morsø's assembly and firing instructions.
- Malfunctions caused by local conditions, draft problems or damage/faults to the chimney.
- Damage caused by overheating and firing with the wrong fuel.
There is soot in my chimney. how did that happen?
If the temperature is too low you might experience tarry soot in your chimney. The combustion temperature will be too low if not enough air is supplied, compared to the amount of wood. Tarry soot is easily recognised as a brown sticky coat. Supply more secondary air to increase the temperature.
A stove flue thermometer placed on the lower part of the flue pipe will indicate if the air supply is correct. The flue gas temperature must be approx. 250°C. If the flue gas temperature is considerably lower, tarry soot may be created in the chimney. If the flue gas temperature exceeds 250 – 300°C, the inside parts might be superheated.
You can expect a slight ticking noise while the stove heats up or cools down.
You can clean the glass using Morsø Glass Cleanser. This must be done when the stove is cold. If heavy soot build-ups appear, use treble ammonia water to clean the glass. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. The secondary air controls must be open and the primary air controls closed. The primary air either from the riddling grate or air control are only to be used during the lighting period or when dry wood is put into the stove. Morsø recommends a moisture content in the wood of 16-20%. If you wan to be sure that wood is dry enough, a moisture meter can be purchased from your local Morsø Dealer.
If there are marks on the stove or it simply needs painting to freshen it up, you must clean the surface first. Rust can be removed using fine steel wool, then painted using Morsø Senotherm spray paint (for black Morsø stoves use coke spray). Please note that MORSO stoves are dark grey in colour not black.
The sealing rope in the door becomes worn after it has been in use for some time, and can start coming away.
The seal is fitted using Morsø ceramic adhesive.
When replacing the seal, the surface must be cleaned thoroughly with steel wool or a steel brush. Seal kits with adhesive can be bought from your local Morsø Dealer. Ensure you use MORSO sealing rope.
The baffle is a consumable item that should be changed as needed. Morsø cast iron stoves have very long life if wearing parts are replaced when they are worn. When letting too much primary air through the grate shaker, the temperature in the combustion chamber becomes very high, and this can shorten the life of the baffle. Another reason may be that there are ashes and soot on top of the baffle. Soot and ash on top of the baffle should be removed 1-2 times a year, this can be done with a brush or Morsø ash tool.
How do I remove dirt from the door glass?
The glass can be cleaned by using an approved glass cleaner. Alternatively warm soapy water and newspaper can be used but only when the stove is cold.
How often should the stove be cleaned for soot and ashes?
The stove needs to be cleaned and serviced fully at least once a year. But naturally depending on how much the stove is used. The baffle is removed from the stove and cleaned up – using a nozzle or a Ash Cleaner. A Ash Cleaner is also suitable for cleaning the rest of the stove. Note that the stove must be cold when cleaned. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. The secondary air controls must be open and the primary air controls closed. The primary air either from the riddling grate or air control are only to be used during the lighting period or when dry wood is put into the stove. Morsø recommends a moisture content in the wood of 16-20%. If you wan to be sure that wood is dry enough, a moisture meter can be purchased from your local Morsø Dealer.
Can I use stove blacking on Morsø stoves?
No, do not use stove blacking on Morsø stoves.
Stove blacking cannot stick to enamelled Morsø stoves; the surface becomes blotched and may flake when the stove is heated.The surface of painted stoves will also become discoloured and blotched if you use stove blacking. Stove blacking should only be used on old stoves that have been ground or sandblasted.
Painted stoves must be painted with Morsø Senotherm paint, and enamelled stoves only have to be washed with hot, distilled water and brown soap.
You can obtain maintenance products and more helpful advice about stove maintenance from your local Morsø dealer.
Your Morsø dealer stocks original Morsø installation and maintenance materials – fireplace mortar, ceramic insulation string, gasket kit for doors, paint, stove kit, glass cleaner, stove blacking etc.
Please ensure that you use the correct spares and maintenance products.
